NEXT ISSUE - NOVEMBER 2015 • Automotive Report • Component Cleaning • Deburring • Dust & Fume Extraction • Honing & Bore Finishing GSF SEPTEMBER 2015 Precision to one one-thousandth of a millimetre - grinding a shroud component for aircraft turbines Shroud segments are sealing elements which maintain a seal between the head of the rotor blade and the turbine housing. Because the conditions inside the high-pressure area of a turbine are extreme, shrouds are made from high-temperature nickel alloys. To reduce weight, components feature the thinnest walls possible, representing a challenge for the grinding process. Clamping, machining strategy and cooling are all factors that play a key role. Haas customers grind shroud segments in just two clamping operations. The overall processing time is just about 15 minutes with profile and shape tolerances of no more than 0.05 mm. Time and quality play an important role, as 40 to 60 shroud segments, depending on the type, are installed in the highpressure area of an aircraft turbine. Grinding has proven to be an economical manufacturing process. To ensure quality, Haas uses a high-precision coordinate measuring machine and a variety of control gauges when machining shrouds. Other measurement technologies are used for other aerospace components such as optical measurement systems and gear inspection machines. Haas engineers are currently working on integrated equipment for measuring mechanical vibration. The mechanical engineers in southern Germany are always looking for a little more precision.

The result of the integration of COMBITEC AG, manufacturer of high-precision internal grinding machines, into the Thun company in 2008, today all internal cylindrical grinding expertise is concentrated in Biel. STUDER's prime aim with this pooling of know-how is to boost the importance of internal cylindrical grinding. Specifically developed system components are applied to the basic machines built in Thun and equipped with extensive grinding know-how, in line with customer requirements. Specially developed loaders or complete automation systems round off the machines. Around 45 internal cylindrical grinding machines are built in the Internal Grinding Competence Center every year, and the plan is to increase sales to 90 machines per year over the next few years. Broad-based internal cylindrical grinding platform The STUDER internal cylindrical grinding platform consists of four areas: basic, universal, radius and production machines. While the S110 and S120 basic grinding machines and the CT750 and CT960 radius grinding machines belong to the established portfolio, the S121 (new at EMO 2015), S131, S141 and S151 universal internal cylindrical grinding machines and the S122 production internal cylindrical grinding machine are part of a completely new modular system. With four machine areas and up to four machines per area, STUDER offers a broad-based machine portfolio which allows the user to specifically access the machine size and technology as required. The S110 and S120 are basic machines which STUDER has equipped with simple technologies such as anti-friction guideways and recirculating ball screws. With the same machine concept and the integration of identical technologies, the machines are differentiated by the machinable workpiece diameters and lengths. The machines have a movable workhead, which always guarantees good accessibility and can be used as a loading axis. Because an integrated loader requires one axis less, the S110 and S120 can easily be automated. The machines can be used with up to four spindles, which are arranged in parallel. 4 The Fritz Studer management (from l to r): Fred Gaegauf, Dr. Gereon Heinemann, Gerd König, Jens Bleher Alternatively, the installation of high-frequency spindles or belt-driven spindles is possible. The S110 and S120 are targeted at users who must achieve low workpiece prices with the smallest possible investment. The S121, S131, S141 and S151 belong to a brand new series of universal internal cylindrical grinding machines from STUDER and can be used to machine workpieces of different dimensions, depending on the machine size. Equipped with up to two external grinding spindles, these internal cylindrical grinding machines can also be used for external grinding applications. The four machine models S121 to S151 are based on STUDER's latest machine technology. They feature machine beds comprising of Granitan® S103 mineral casting, as well as the StuderGuide® guideway system with linear motors or the newest generation of glass scales, technologies previously only available in STUDER's universal and external grinding areas. The Thun company is thus entering a completely new dimension in internal cylindrical grinding technology. The series is aimed at precision grinders and with them the entire spectrum of workpieces that require high-precision internal grinding. With the S141 and S151 STUDER is also particularly aiming at manufacturers of main spindles. The CT750 and CT960 radius grinding machines represent a niche in internal Grinding & Surface Finishing n SEPTEMBER 2015 cylindrical grinding and are used to machine extra hard materials such as tungsten carbide, ceramic or sapphire. Simply shaped diamond tools are generally used for grinding such materials. So that complex component geometries can also be created with these shapes, the workpiece moves around the grinding wheels. The CT750 and CT960 are therefore equipped with a swivel axis or a full-blown interpolating B-axis, which enable turning of the workpiece and the production of ground and polished radii in the oscillation grinding process. These machines, which are available in two sizes, also feature the latest STUDER technology, such as a turret with direct drive or directly driven B-axis. The area of application of the machines is the manufacturing of draw dies, piston or hydraulic components. The STUDER internal cylindrical grinding platform is completed by the S122, a pure system machine for production. This GSF SPECIAL REPORT 4-5_ES CONTENTS 4-5 21/08/2015 11:34 Page 5 SPECIAL REPORT machine was designed for the production of hydraulic and automotive components. Equipped with up to three spindles in a linear arrangement and an integrated quick loading concept, STUDER has placed the priority on minimising auxiliary times with the S122. The system machine is always application-specifically equipped, depending on the workpiece and the specified process. As the extensive know-how of the Internal Grinding Competence Center in terms of technology and process design is incorporated into the machine design, the customer gets a quick machine and an optimised grinding process. Minimised to the max The S121 from STUDER is a universal internal cylindrical grinding machine for medium-sized workpieces in individual and small batch production and will make its worldwide debut at EMO 2015. and direct measuring systems guarantee exceptional interpolation accuracies. Although the smallest machine in the universal series in terms of space requirement, larger diameters can be machined on the S121 than on an S131. This makes it a high-performance machine with an impressively compact design and excellent ergonomics. STUDER's offering of high performance in a small footprint with the customized S121 is evident in the swing diameter over the table of 400 mm and the maximum workpiece length of 300 mm, with a maximum grinding length of 175 mm for internal and 100 mm for external diameters. This large range of workpiece dimensions is made possible by optimal arrangement of the machine components. Tailored to the perfect size The configuration of the S121 as a tailor-made machine is above all made possible by the fact that the machine can be equipped with a fixed spindle or a spindle turret with two spindles. When using a spindle turret, the turret swivels hydraulically through 180° to a stop, and one spindle can be fitted with an external grinding wheel. However, STUDER also Equipped with the advanced technology implements the "tailor-made" principle of its sister machines S131, S141 and S151, through a workhead with manual cylindricity this series model has been limited to the correction, which is adjustably mounted on essential equipment. A striking example is the workpiece table, and a high-resolution the spindle turret, which swivels through C-axis with direct measuring system, which 180° to a stop and is equipped with two is ideally suited for form and thread grinding spindles. Alternatively a fixed grinding. The machine concept always spindle is possible. With the S121 STUDER allows optimum accessibility for the has thus created a tailor-made machine for operator, whether for workpiece internal, surface and external grinding of changeover, dressing or changing the chuck components, which offers exceptional grinding wheel. value for money. While a T-slide The S121 is a universal internal cylindrical arrangement or the use of maximum two grinding machine, which is designed for the tools guarantees the attractive price, the production of high-precision parts. The manufacturer has made no compromises in basis for this precision is the machine bed terms of the advanced technologies used. comprising of Granitan S103 which, with its This is evident in the StuderGuide guideway excellent cushioning and thermal behavior, system for the X- and Z-axis, which ensures outstanding surface quality of the guarantees high geometrical traversing and ground components. The excellent guidance accuracy through the entire speed cushioning behavior also extends the range, together with high load capacity and service life of the grinding wheel, which in cushioning levels. At the same time the turn reduces auxiliary times. As the machine combination of StuderGuide, linear motors bed largely equalizes temporary temperature fluctuations, a high dimensional stability is ensured throughout the machining time. The modules of the S121 are ideally suited to each other and produced with the customary STUDER precision. The large distance between the guideways and the very rigidly constructed slides are further cornerstones for the precision and productivity of this machine. Simple, reliable programming and efficient operation of the S121 is guaranteed by the StuderWIN software. The possibility of fully integrating the in-process gauging and sensor technology for process monitoring as well as contact detection and automatic balancing systems in the control enable standardised programming of the different systems. The drive elements are optimally adapted to the control. The S121 is tailor-made for a large range of internal grinding applications. Numerous applications are in the production of machine tools, drive elements as well as in the aircraft and die industries.

Klaus Lehnen, the MD of Surface Technology Products Ltd died peacefully at his home in Solihull in July. Born in 1941 in Hannover, Germany, he joined VSM Abrasives at their headquarters there to do his technical apprenticeship. In the early 1960’s, VSM was trying to build up its presence in the UK and he was sent to the company’s London office/small business unit to develop the business, moving on to Manchester and Liverpool. He left VSM to develop sales at TESA Tapes industrial division, part of the large Beiersdorf group. He then relocated to the Midlands, and came up with the idea of starting his own company, initially called Hilzinger Balmond Abrasives. The ethos was always to introduce new ideas and technology into the UK abrasive and polishing/abrasive machinery market. In 1973 the company name was changed to Surface Technology Products or Surtech for short, and the focus was on selling abrasive and polishing machinery, not just consumables. Klaus was a pioneer in making the link between solving customers’ problems and issues with a combination of the correct machines and consumables, a fairly ground breaking concept at the time. From the 1980s onwards, the focus was on portable tools, especially with the now very famous US brand Dynabrade which Surtech helped build up in the UK. The sales network was expanded to promote these machines and other brands of pedestal machines via industrial abrasive distributors. The company worked very closely with 3M to reinforce the link between the correct tool and abrasive for the application. Under Klaus’s leadership, the company was able to build up an unrivalled range of machines from across Europe and even the world, had the best technical reference library for anything to do with the industry, and forged numerous contacts with all the European abrasive machine tool suppliers and manufacturers. He had a vast knowledge of the industry, problem solving and applications, wrote editorials, created his own leaflets and brochures, as well as press releases. The subject was his passion and hobby at the same time, but he still made time to do what he liked, travelling, the great outdoors, good wine and food Klaus was a pioneer in many ways. He was an immense help when we launched Grinding & Surface Finishing and we shall miss his knowledge and understanding of our business, as well as his friendship. His death marks the end of an era, as he was old school, honest, hardworking, forthright sometimes, but above all had conviction of doing what he thought was right 3M’s latest innovation recognised at BSIF Safety Awards ceremony 3M is celebrating after winning a prestigious award for its latest revolutionary product, designed to improve occupational health for respirator users in the workplace. At the Safety and Health Expo, held in London, the diversified technology company won a British Safety Industry Federation (BSIF) Award for its Organic Gas and Vapour End of Service Life Indicator Filters. The Safety Awards are highly regarded in the health and safety industry and judges awarded accolades in three categories: product innovation, service award and safety excellence. 3M’s filter, which is the first of its kind, won the product innovation category. The product utilises the company’s End of Service Life Indicator (ESLI) Technology to help respirator users in appropriate environments determine when a filter needs replacing, so they are not exposed to certain harmful organic gases and vapours. Currently, some users change their filters only when they can detect contaminant odour, taste, or irritation inside the respirator, with the result that the harmful substance has already broken through. To combat this problem, the ESLI Technology is located inside the filter next to the activated carbon. As organic vapours travel through the filter, they are also absorbed into the ESLI Technology. As this happens, the indicator changes colour, visually marking the course of the organic vapours through the filter. Dependent on the viewing angle, the user will either see a red bar on a green background, or vice-versa. Once the bar reaches the end-of-service line, the filter will need replacing. Jenn Raymond, senior marketing executive at 3M, said: “We are delighted that the Organic Gas and Vapour End of Service Life Indicator Filter has been recognised at the BSIF Safety Awards. This is such an innovative product, which will really make a difference to occupational health, so it is fantastic that this has been reinforced by the BSIF accolade.” 3M and 3M Science Applied to Life are trademarks of 3M Company To learn more about 3M's creative solutions to the world's problems, visit www.3M.co.uk or follow @3M_UK on Twitter Grinding & Surface Finishing n SEPTEMBER 2015 7 GSF EMO PREVIEW 8-17_ES CONTENTS 4-5 19/08/2015 14:14 Page 8 EMO PREVIEW Avanti a Milano After six years, EMO, the worldwide exhibition of machine tools returns to Italy. Promoted by CECIMO, the European Association for Machine Tool Industries, the tradeshow will take place from the 5th to the 10th of October 2015 in the prestigious fieramilano exhibition centre. The biennial leading machine tool event, whose trademark is owned by CECIMO, has chosen Milan as one of its locations alternating with Hanover. This reflects both the foresight of the organisation, relying on a long-standing experience in the organisation of events and the status of the city in showcasing the expertise of the Italian industry, which ranks fourth worldwide for production and third for export. More than 110,000 square metres of net exhibition space was already booked six months before the opening of EMO MILANO 2015 and the previous 95,000 sq m of exhibition occupied by the 2009 show has been exceeded. Should the current trend be confirmed it is predicted that the exhibition will occupy 120,000 sq m. More than 1,300 companies are already registered to exhibit at EMO MILANO 2015, with, of course, Italian companies to the fore, closely followed by the Germans, the Taiwanese, Chinese and Swiss. 8 committed to transforming the concurrence of the two tradeshows into real opportunities for our operators, by planning The halls of the exhibition centre of ‘connection activities’ and by activating fieramilano Rho-Pero will host the biggest numerous special services.

Haas will be showing its latest grinding machines used for the production of parts such as cutting tools, turbine blades and medical components such as artificial knee joints on stand G12/H11 in Hall 14. Magnetfinish will be exhibiting its latest deburring machines that are commonly used for rotary cutting tools and inserts on stand A17 in Hall 10. On home soil, the Italian specialist grinding machine manufacturer Nova completes the trio of companies, showing machinery on stand H14 in hall 14. The Nova stand will be of particular interest as the Italian grinding machine specialist is exhibiting one of its latest internal grinding machines. Nova’s core business is manufacturing grinding machines for external, internal and the multi-surface grinding of components ranging from 3 mm to 480 mm OD as utilised in the bearing, automotive and aerospace industries, with the bearing industry being the major market sector served by Nova. The production of CV Joint components is another application for which Nova supplies special machines. Nova’s special machine division produces machines for grinding parts of up to 800 mm in diameter. Key customers include bearing manufacturers such as INA, FAG and Barden (The Schaeffler Group) as well as SKF, Timken and NBC. Other users of Nova grinding machines include Eaton, Delphi, Bosch, Ford and GKN. At EMO Nova is exhibiting the Novamatic 2G machine which provides very high productivity and allows for extremely tight tolerances to be held with statistical control. The machine’s unique wheel head design enables a contamination-free environment for the slides and it has a fixed work head unit for maximum rigidity and easy automation. The CBN grinding wheels employed on this machine are dressed by means of a high-frequency spindle with cup wheel and the machine benefits from automatic taper correction and is fitted with a compact integrated automatic robot based loading system. Nova currently employs around 150 people at its 14,000 sq m HQ in Zola Predosa, Italy with an impressive 22 percent of employees in research and development. Turnover this year is looking to exceed Euro 50 million. Nova continues to expand worldwide with currently 45 percent of its grinding machine sales within Europe, 25 percent sold within the NAFTA area and 30 percent to the BRIC countries. Magnetfinish supplies machines to specialist tool manufacturers who are using this unique technology to offer end users within the aerospace and mould and die industries premium solutions whereby the finest and most highly precise milling cutters, drills and taps are required for arduous machining tasks. After being produced by a grinding process, cutting tools of all types can suffer from having jagged and sometimes very sharp cutting edges as well as micro sized burrs. These impact heavily upon the 14 Grinding & Surface Finishing n SEPTEMBER 2015 lifetime of cutting tools and can also affect their performance during heavy cutting and this often means that tools cannot be used at optimum speeds and feeds. When milling, drilling or tapping at extreme speeds the resulting high temperatures that develop at the cutting edges are the main source for such problems because the tool becomes highly susceptible to wear and even fracture. Deformed hot chips, which may even weld to the tool surface and form built-up edges, also greatly impair high-speed machining. The subsequent jamming of chips or even more minor impairment to chip flow that results from this quickly brings about a premature end to tool life. The patented Magnetfinish technology that has been developed by Dr Wolfgang Thiel of Magnetfinish addresses this problem. Haas will be highlighting the production of cutting tools on its latest CU machine. This compact tool grinder is only 1.6 metres wide, with an integrated 14 station wheel changer. It’s 12 Kw grinding spindle has ample power for the production of tools of all kinds and since its launch late last year Haas have gone onto supplying many of these machines to major cutting tool manufacturers. Despite being very compact, the Haas CU has a general working envelope of 300 mm long x 180 mm in diameter making in easily capable of manufacturing the vast majority of cutting tools. The automatic change of wheels and coolant nozzles is catered for as is the auto loading of parts and wheel dressing.

Two test pieces have been created that highlight the high productivity features of the machines as well as the exceptional levels of precision that can be maintained over extended periods of operation. On the cylindrical grinder, which has a capacity of 1,000 mm between centres and a maximum workpiece diameter of 280 mm, a non-cylindrical part will be machined. Flats will be ground on a 15 mm square to an accuracy of eight micron, with each face flat to within two micron. This demands precise control of the angular position spindle relative to the X axis wheel head slide. Hydrostatic bearings enable small axial incremental movements to be synchronised with the main spindle drive without encountering slip/stick problems Similar accuracies can be achieved when grinding other cross-sections such as triangular, hexagon, ’D’, ovals or ob-rounds. On the CNC surface grinder with its 800 x 400 mm table, visitors will see a profiled section being ground using the CNC system to generate the profile across the table. Digital scales give absolute measurements for the traverse (Z-axis) and vertical (Y-axis) to maintain profile accuracy. The CNC control allows the profile to be monitored and modified in real time via the interactive screen. Other key machine features include a ball screw driven X axis on the table, frequency converter for constant cutting speed, and finally a range of optional dressing cycles. Both machines are fitted with Fanuc CNC controls and axis drives with one important addition: the software for the interactive screen and operator interface was specifically written by GER to incorporate many features specific to the grinding process. For example, geometric profile corrections for taper, barrelling, and camber are standard. Other facilities take in air gap elimination and collision management as well as wheel data storage together with automatic wheel dressing. The CNC system also introduces closer integration between various axis movements. On the cylindrical grinder, for example, the spindle movement (C-axis) and cross slide (X-axis). This directly contributes to the levels of accuracy essential for grinding precision non circular cross sections. For maximum customer support, all machines in the field can be supported by internet diagnostics.

The exciting new 202 TG will be demonstrated at EMO in HALL 7 Stand A02. The 202 TG has been developed to improve productivity, precision and component quality, whilst reducing setup and cycle times with three operations in one machine tool that can operate simultaneously. Created as a flexible solution, the new 202TG is as comfortable in a production environment as it would be producing small batch runs and prototypes. The new 202TG has a machining diameter capacity of 80 mm with a maximum machining length of 160 mm, whilst the headstock offers a maximum through-bore of 19 mm. Schaublin Machines is a manufacturer synonymous with power and precision and the latest offering has a continuous headstock torque of 35.1Nm with a spindle speed capable of reaching 7000 rpm. The stroke of the X1-X2 and the Z1-Z2 axis is 160 and 300 mm respectively with the ability to reach working feed rates of 8 m/min. As one of a select few products on the market to seamlessly offer hard turning, milling and grinding in one machine, the 202TG provides thermally-cooled grinding spindles with exceptional power and speed outputs. When developing the new 202TG, Schaublin Machines had a set of target criteria that it wanted to achieve. The recent launch of the new machine bears the fruit of the company's achievements with a hard turning and grinding centre capable of milling through its driven tooling stations. In developing the 2020TG, the Swiss manufacturer focused upon creating a machine tool that is extremely precise and suitable for machining small diameters whilst offering modularity and an ergonomically friendly design for ease of use and flexibility. Part of this flexibility is the ability to accept collets and chucks for workholding and the ability to integrate the machine into an automated environment with a bar-loading facility and the easy integration of an unloading arm or conveyor if desired. At the base of the machine the quality is apparent. The 202TG has spindle and servo motor cooling to prevent thermal instability and to guarantee that accuracy is maintained on long production runs. The spindles are driven by synchronous motors that can start, hit top speeds and stop significantly faster than competitor machine tools. This quality is also built into the cross slide with glass scales delivering a resolution of 0.0005 mm to ensure unparalleled accuracy and repeatability. With previous machines that offer turning and milling with a grinding facility, a key concern to end users was the ability of abrasive powders and materials to create friction and wear of the moving parts of the machine. However, Schaublin has covered this base with all moving parts being fully protected to ensure a long service life of the new 202TG. The optional revolving tool turret on the new 202TG 16 Grinding & Surface Finishing n SEPTEMBER 2015 utilises a VDI16 system that accommodates up to 12 tool positions with up to six tools having driven capability. With a maximum rotational speed of 6000 rpm and a 7 Nm torque, the turret offers flexibility, power, speed and rigidity to meet all the machining needs of the end user. Further options include the internal and external grinding spindles for precision production beyond the realms of alternate machine tools. The internal spindle offers a maximum speed of 60,000 rpm and a power output of 6 kW, while the external grinding spindle has a maximum speed of 25,000 rpm with a power output of 7 kW. As both spindles are controlled by a synchronous motor, the power, efficiency and ability to reach operational speed rapidly are unrivalled. As waste removal is an issue with such a diverse machine, the 202TG incorporates a chip conveyor system for removal of chips whilst grinding waste is controlled in the 300 litre coolant sump that has paper filtration for waste as small as 10 to 20 microns.

The tool management system better enables the management of dressable and non-dressable wheels. For dressable wheels, the user can now select the maximum amount of allowable wheel wear, in millimetres or inches, before the wheel should be changed. This is used in conjunction with the AutoSize program, a cycle for automatic sizing wheel diameter. Through the AutoSize program, the control monitors and automatically detects when the maximum amount of wheel has been dressed off or, otherwise, removed through the grinding process. This removes the manual process today of checking for wheel wear. For non-dressable wheels, the system enables the user to set the maximum amount of time the wheel can be used before a replacement tool is required. Easy-to-access screens will show the user, in real time, how much time a wheel has left before it needs to be changed. These enhancements help improve the grinding process by automatically keeping track of the tool’s life. In addition to these enhancements, the tool management system allows a user to easily update tool information (tool length, wheel diameter, wheel thickness). Once tool information is loaded, it is stored for use by the AutoSize and the Wheel Dressing programs. These programs have been enhanced for faster setup whether utilising a Renishaw OMP400 Probe or a conventional indicating process. The Moore Tool Company manufactures a complete line of jig grinders and has a precision manufacturing business certified to ISO 9001:2008 and AS9100C. The company is ITAR registered. Moore’s machine tool business builds fully automated and highly productive CNC continuous path jig grinders.

Tim Kern is responsible for demonstrating the machines and for setting up the grinding processes on customer premises. His specialities include the grinding of medical implants and instruments as well as machining parts for the aerospace industry. Wolfram Hermle manages the software development at Haas. With the Multigrind Horizon software, he and his team have developed a completely new type of grinding software whose advantages are particularly appreciated by users in the aerospace segment. They were asked about the role of Haas in the aerospace industry. Where are the Multigrind grinding machines used in the aerospace industry? Wolfram Hermle: Haas users machine a variety of workpieces ranging from IP (intermediate pressure) compressor blades through to HP (high pressure) turbine blades, HP vanes or HP shroud segments for aircraft engines. These are all components in the high-pressure area of an aircraft turbine which are exposed to extremely high thermal and physical stresses. Here, we are dealing with very demanding materials which are hard to machine. You can only use grinding for that. The complete machining of turbine blades with the Haas sandwich clamping process How do you see Haas’ position in the aerospace industry? Tim Kern: We encounter a lot of technical expertise, from engineers and technicians who know what they want. In comparison to medical equipment, the technical specifications are much tighter in this sector. We have the technical ability to meet the high requirements which prevail in this sector, with our grinding software, our grinding machines and our experience. That spreads by word of mouth. What are the technical challenges when grinding aero engine components? Wolfram Hermle: Our customers want absolutely reliable, absolutely robust processes with which they can achieve reproducible quality. One component should be just the same as the next. Tim Kern: These challenges from aero engine makers are just what we like to hear. Where possible, we only clamp a component once, then measure it and machine it in a single operation to produce the finished item. Having to re-clamp several times must cost time? Wolfram Hermle: And money, plus above all, precision. Fewer clamping operations also mean that the workpiece spends less time waiting around, thus shortening the cycle times. You have fewer half-finished, expensive components lying about, require less effort for quality assurance and measurements and need less staff, as they don’t have to operate five machines, just a single grinding machine. Tim Kern, demonstrations manager, and Wolfram Hermle, software development manager at Haas 18 Grinding & Surface Finishing n SEPTEMBER 2015 What does quality assurance look like at Haas? Wolfram Hermle: At Haas, we work with a variety of measurement technologies, including three-two-one measurements to exactly locate the workpiece in space. In this GSF AEROSPACE REPORT 18-21_ES CONTENTS 4-5 19/08/2015 14:29 Page 19 AEROSPACE REPORT type of measurement, we have three points to define the plane, two other points then define the axis and the third point is then on the workpiece itself. In itself, this is nothing completely new, but so far it has not been common practice to use the integrated three-two-one measurement when grinding. Especially not in the way that we further process the result of the three-two-one measurement with our Multigrind Horizon grinding software. This automatically adapts the grinding program to the workpiece’s exact position in the working space. In this type of measurement, we have three points to define the plane, two other points then define the axis and the third point is then on the workpiece itself. In itself, this is nothing completely new, but so far it has not been common practice to use the integrated three-two-one measurement when grinding. Especially not in the way that we further process the result of the three-two-one measurement with our Multigrind Horizon grinding software. This automatically adapts the grinding program to the workpiece’s exact position in the working space. workpieces. All of the measurement functions and the dressing technology to dress the tools in the process are included in the basic package. To what extent does the casting of high-pressure compressor blades in affect the dimensional accuracy of the part? Tim Kern: It is expensive and time consuming. The position of the part plays a responsible role in this. It means that the process decides whether I get a good part or an expensive reject. Wolfram Hermle: With the three-two-one measurement and the Haas sandwich clamping, we have the technical ability to compensate for casting tolerances. When measuring a compressor blade, if deviations such as a visually imperceptible warp are revealed, then the measurements will be introduced into our grinding program. We correct casting faults in the grinding process. This permits optimum efficiency to be achieved for the engine. What sort of materials are we dealing with for turbine components? Which software module does a user from Tim Kern: Alloys, titanium, titanium the aerospace industry need? aluminium alloys, aluminium alloys and Wolfram Hermle: With the Multigrind ceramic coatings. These are all materials Horizon® 3D-CAD package and the 3D-CAM which can withstand the enormous physical package, users can cover about 90 per cent stress within a turbine. Important of all grinding tasks in turbines. If users also characteristics here include low weight, high want to machine, then they will also need operating temperature and tensile strength. the package for rotationally symmetrical How do you see the role of the grinding software in the overall grinding process? Tim Kern: Our grinding software is becoming ever more important and powerful, especially in the high-precision area where one one-thousandth of a millimetre is important. Our Multigrind Horizon can generate a lot more than grinding paths. It is a genuine CAM system, a grinding programming system, a tool management system, a robot-handling program, an interface to a measurement system and, last but not least, operating software which is really easy to use. Our grinding software is so flexible and has so many facets that both the designer in the development department as well as the operator of the machine can work with it – each at their own user level. Wolfram Hermle: Working with varying rights or user levels has the advantage that a validated grinding process as required by the FAA (Federal Aviation Administration in the United States) cannot be changed by an unauthorised person. This means that the Multigrind Horizon ensures traceability at all times of who changed what and when in the grinding process. This documentation of absolutely everything is mandatory in the aerospace industry. What do aerospace industry customers attach the most importance to? Tim Kern: Our users want a grinding process which has been properly run in and which will produce faultlessly from the very first day. This means developing robust processes and then automating them. And the processes should work just as well in the United Kingdom as in France, China or the United States.

One of Makino’s significant technology advances that dates back 17 years was the development of VIPER creep-feed grinding in collaboration with Rolls-Royce. It was introduced for highly productive manufacture of nickel alloy aero engine and land turbine parts, notably blades, vanes, blisks and casings. It revolutionised machining of these components, as it was capable of stock removal rates up to eight times those achievable when grinding nickel alloys using a plated CBN wheel. Broaching, milling and turning operations could also be eliminated and consumable costs were drastically reduced. The original Makino machines deployed for VIPER grinding were versions of its horizontal machining centres with modified guarding to accommodate the very high volumes of coolant that are necessary to prevent burning of the nickel alloy. Small, aluminium oxide grinding wheels in standard 40-taper back ends were housed in the tool magazine along with milling cutters, drills and other tools, allowing additional operations to be performed in-cycle. An ingenious, programmable nozzle assembly was developed to maximise coolant delivery to the point of cutting. A further development was continuous dressing of the wheel during grinding as an alternative to intermittent dressing using table-mounted rolls. A large Makino A99e was shown at the recent NCMT Open House with a 1,250 x 1,100 x 1,250 mm working area, with this modified VIPER configuration. It was devoted to demonstrating in-process Makino A99e with Delcam OMV software NCMT EasyGrind Max PC – new CAD screen inspection software from another Open House partner, Delcam. A Renishaw probe was programmed using Delcam OMV (on-machine verification) software to complete an inspection routine around a guide vane and its fixture. The latter’s location points were verified to pick up any clamping issues. Measurements on the component itself avoided having to remove it from the A99e to check dimensions on a coordinate measuring machine, only to find that further metal removal is necessary. Putting the part back in the fixture accurately would require a lengthy manual clocking process using gauges, so avoiding this saves time and eliminates the chance of introducing inaccuracies. Measured results from in-process probing were downloaded to a Delcam engineer’s laptop, where they were correlated with the CAD model of the vane. Following the success of VIPER grinding and its worldwide acceptance by manufacturers in the aerospace and land turbine supply chains, Makino produced its first purpose-built, 5-axis machine in 2008, called iGrinder G5, designed specifically to exploit the technology to the full. As with all VIPER grinding platforms, it is available through Makino-NCMT Grinding Division, a company formed to market the turnkey manufacturing systems across Europe and Scandinavia. The iGrinder G5 is 10 percent quicker at machining nickel alloy components than the modified 20 Grinding & Surface Finishing n SEPTEMBER 2015 Makino A55e machining centre that preceded it. Metal removal rate is of the order of 80 cc/min and the machine accepts parts nominally up to 300 mm in diameter. The enhancement in grinding efficiency comes from a number of factors, including an increase in linear rapid traverse rate from 40 to 48 m/min. Work head speed more than doubled to 100 rpm, which is especially beneficial when grinding smaller components. Probably the most critical improvement, however, is in the design of the programmable coolant nozzles. They are more versatile on the iGrinder G5, as they may be positioned by two rotary NC axes anywhere through 360 degrees around the periphery of the grinding wheel, rather than through just 180 degrees, as was the case with the A55e. To achieve this greater degree of freedom, power and coolant supplies are built-in, rather than being delivered through an umbilical cord. Nozzle positioning speed is faster and therefore more responsive when changing position to direct coolant accurately towards the point of cutting. At the Open House, the iGrinder G5 was shown roughing and finishing the tooth profile of an involute gear and the front and back diameters in a single set-up. It was an aerospace actuator gear machined from a stainless steel blank. NCMT has identified gear production as a good prospect for increased business and has a number of enquiries pending, including for the manufacture of racks. Related technologies that have been GSF AEROSPACE REPORT 18-21_ES CONTENTS 4-5 21/08/2015 14:30 Page 21 AEROSPACE REPORT developed by Makino-NCMT to achieve world class process capability and throughput include EasyGrind Max PC, a new release of software that, unlike its predecessor, integrates CAD and computerised cycle simulation capability, creating powerful stand-alone functionality. While the G5 accepts parts nominally up to 300 mm diameter, with increasing aircraft engine size some bigger vanes fall outside the machine's working envelope. Consequently, the larger iGrinder G7 was introduced in early 2012 to address the problem, bringing the smaller end of industrial gas turbine components within its scope. The machine, with a capacity of 730 mm in X by 650 mm in Y and 730 mm in Z, has a similar specification to the G5, complete with programmable 2-axis coolant nozzles, but differs in having dual rolls to dress the bigger grinding wheels. The Open House event showed this machine equipped for VIPER grinding of turbine blades from gamma titanium aluminide. The material has excellent mechanical properties including lightweight and oxidation and corrosion resistance at temperatures of over 600°C, making it a viable replacement for traditional PO 900 BF nickel-based superalloy components in gas turbines. NCMT has been carrying out exhaustive trial machining of the material by VIPER grinding and traditional metal cutting. For confidentiality reasons, it is unable to comment at this stage on the metal removal rates achieved, the mechanical properties of the machined parts or the customers for Makino iGrinder G5 machining an involute gear which the applications engineering is being carried out.

The Engineering Quest offers a comprehensive range of realisation assessment, prototyping, product development and manufacturing services, working with customers across a diverse range of industries on products ranging from high pressure diesel pump parts to gas and oil components, prosthetics and oil field equipment. Common denominators across Quest’s activities are meeting very high tolerances, sub-micron accuracies and challenging materials which can include HSS steel grades with a hardness in excess of 70 Rockwell, polycrystalline diamond and aluminium-silicon castings. The company has a long history of operating Kellenberger manual and CNC internal and external grinders, which are supplied and supported in the UK by Jones & Shipman Hardinge, based in Leicester. Delivered in December 2014, the latest machine, a high specification Kellenberger Kel Vista with triple wheel head options fitted, has been initially dedicated to development work on 3000 psi capability high pressure diesel injector pumps. The Engineering Quest has developed these with Woodward Diesel Systems for use on mid-range diesel engines used in marine and construction equipment applications, and, with the capability to undertake medium batch production work, the grinding machine will now be applied in this area. The Kel Vista is a highly productive and capable universal grinding machine with a programmable B axis indexing to 1º as standard to allow up to two external and one internal grinding wheel to be used in the same setup. Micro-adjustment of the tailstock and semi-automatic balancing of the grinding wheel are just two more of its many features. Its construction features linear guides on the X-axis, a classical side arrangement on the Y-axis, a grinding length between 600 and 1000 mm and a swivelling work head suitable for grinding between centres or chucking work, with thermally optimised bearings to guarantee highest roundness and dimensional accuracy. These features and others were instrumental in The Engineering Quest’s purchasing process, as managing director Steve Matheron explains: “We offer a very different range of services to those offered by other subcontractors. We actively encourage customers to see us as their product development partner offering component manufacture, process expertise and cost Steve Matheron (right), managing director of The Engineering Quest, believes the recently acquired Kellenberger Kel Vista universal grinder can work on any number of projects in the firm’s Milton Keynes factory 24 Grinding & Surface Finishing n SEPTEMBER 2015 The Engineering Quest’s recently acquired Kellenberger Kel Vista universal grinding machine is used on both product development and production volumes avoidance planning,” he explains. “Specifically we added the Kel Vista to our grinding inventory because of the diesel injector project and the move into the production manufacturing phase. But of course it has great all round capabilities and will complement any number of other projects we are working on. “Having worked through the development and proving stages on the diesel pump components it was important to have the capability and capacity to progress into production volumes. “This in turn necessitated we have a grinding machine offering absolute repeatability bearing in mind the tolerances of 2 micron geometric and 5 micron linear while maintaining production speeds,” he explains. Winterthur Technology is the preferred grinding wheel supplier to The Engineering Quest and, coupled with the qualities and grinding process flexibility offered by the Kel Vista, the company feels it is achieving a good balance between high precision, excellent repeatability and productivity for production capacity.

Ever since 1950, gear design and production has been the core competency of the Tunbridge Wells-based company. Now in its third generation as a family-owned business, its focus is firmly on maintaining its reputation and continuing to invest in the latest machine tool technology to deliver the quality and service that this reputation has been built on. ISO 9001 and aerospace BS EN 9100 compliant and accredited, Muffett Gears’ specialism is in the design and manufacture of gears and gearboxes, with a capability to produce prototype and first batch production for customers, as well as production of a range of standard products, including spur, helical, bevel, racks, worm and wormwheels, internal gears and moulded gears, with batch quantities ranging from 1 off to 1000 off. With a customer base that covers aerospace, medical, mining, defence and construction, it is called upon to manufacture gears of all shapes and sizes, from minute gears that are used in artificial hands through to large shafts for industrial pump systems. Other projects have included manufacturing components for medical scanners and camera mounts to supplying gearboxes that end up in the latest commercial aircraft designs. To achieve the five micron accuracies that some of their work calls for, Muffett Gears has an extensive plant list capable of cutting any form of gear. It also has a capacity list of more conventional machine tools, one of the more recent being a Perfect PFG-D4080AH surface grinder from RK International Machine Tools. The Perfect grinder is NC controlled and was purchased to replace an ageing manual grinder, with one specific component in mind, spur gear filler plates used in an oncology radiotherapy machine. The old machine was becoming inconsistent and required constant manual intervention to maintain size, which was impacting on productivity. The Perfect PFG-D4080AH is improving productivity at Muffett Gears through its consistency and table capacity 26 Grinding & Surface Finishing n SEPTEMBER 2015 Having researched the market, the Perfect PFG-D4080AH stood out from the crowd due to its simplicity of operation and cost: “Many of the surface grinders that we looked at were over-specified for what we wanted, which in turn meant that they were more expensive,” explains Muffett Gears works engineer Alan Kennard. “Our requirement is pretty straightforward: we needed a grinder that would be consistent and accurate, without all the bells and whistles, but would give us some level of automation, while at the same time allowing manual operation for when we needed to use it as a toolroom grinder.” Another advantage of the Perfect PFG-D4080AH for Muffett Gears is the table size, which at 400 mm by 800 mm allows three components to be ground in a single setup as opposed to two on the old machine. This has an immediate impact on lead times and productivity giving a 40/50 percent improvement with around a 90 percent reduction in input from the operator. Shift supervisor, Rob Hudson adds: “We had no previous experience of NC surface grinding, but setting the Perfect machine couldn’t be simpler. We simply touch down on the work dial in the amount of material to be removed and set the number of passes. We tend to work on 50 micron roughing passes with a 25 micron finishing pass. After that it is case of pushing the button and waiting for the cycle to finish. The machine grinds to size every time and we have never had a scrap part from it in the time it has been installed. Compared to the old machine we have total control of sizing, GSF PRODUCTION GRINDING 22-31_ES CONTENTS 4-5 21/08/2015 10:10 Page 27 Production Grinding if we want to remove another five micron, we simply dial it in and the machine will remove exactly five micron.” The consistency and accuracy of the Perfect PFG-D4080AH is due to its construction, with the column and base manufactured from CNC C NC SU S SURFACE URFACE G RIN INDERS… S… GRINDERS… GER G ER m ER manufacture anufacture precision precision grinding grindi ding machines m achines in in Spain.

During the two-day event, Klingelnberg experts presented their innovative product developments and solutions to numerous customers and business partners. The event afforded a live view of many new developments, with a number of interesting presentations demonstrating just how fascinating machine designs in gear technology can be. The show's highlights included presentations of the advanced vertical concept on the new C 30 and G 30 bevel gear machines, the new P 16 precision measuring centre designed to measure small workpieces, the new BC 12 measuring device for precision measurement of stick blades, as well as a presentation of new tool systems. Klingelnberg covered a broad range of topics in interesting lectures, in which the significantly less load on the drive components and a stiffer design of the overall system. A major new feature of the machine series is the innovative operating concept with state-of-the-art control technology: The touchscreen display with a newly-developed operator guidance facilitates intuitive machine control compared with standards typically seen in the marketplace. company’s experts reported on current challenges in drive technology and the company's unique Closed-Loop concept for gear manufacturing, among other topics. ARCOFLEX innovative tool system Klingelnberg is a leading manufacturer of gear cutting tools in addition to machine tools and precision measuring centres and as such it is only fitting that the company also presented a new tool system at the in-house exhibition. The newly developed ARCOFLEX system is ideal for producing individual gear sets and small batch sizes. This is due to the fact that only one cutter head setting is needed to produce pinions and ring gears of different sizes. Founded in 1863, the family-owned Klingelnberg company is one of the leading companies in the gear industry. Thanks to numerous innovations in the areas of New standards in bevel gear machining Built on the same design concept, the C 30 bevel gear cutting machines and the G 30 bevel gear grinding machines are setting new standards in the gear machining industry. All bevel gear machines in this most recently developed series are equipped with a heat-stable, vibration-damping machine bed. Thanks to the optimised axis arrangement of the machines, reduced traversing paths ensure Precision measuring centres – reliable down to the last detail In the area of gear measuring technology, Klingelnberg presented its trendsetting P 16 precision measuring centre, designed to measure small workpieces. The P 16 owes its compact size to an innovative modification; thanks to a newly developed workpiece clamping system which is optimally adapted to accommodate small workpieces, there is no need for a counter support. 28 Grinding & Surface Finishing n SEPTEMBER 2015 calculation, production, and measuring technology, Klingelnberg maintains its leadership position in this sector.

However, at the same time, the technologies are also becoming more complex, for example in the aviation, aerospace and marine industry or the automobile industry. Nevertheless, the use of these precision machine tools must remain simple and MIKROMAT, a world-leading manufacturer of precision machine tools, relies on the controls of Schleicher Electronic Berlin in its thread grinding machines. In the domain of precision manufacturing, CNC machines have replaced manually operated machine tools for a long time. These days, operation is achieved via an electronic box and computer programs, rather than manually with levers, cranks and handwheels. In this way the machines can be adjusted and monitored with considerably more precision. The truth is that the classic CNC programming via G-Code is complicated and cumbersome as each program step must be entered individually, manually, in the input screen of the HMI device. Up to 1,000 lines of hand-typed commands quickly come together. In addition, the classic CNC control panel is confusing, as it is composed of countless buttons with various letters, numerals, characters and symbols. This is the reason why MIKROMAT adapted its thread grinding machines 26 years ago. Here, the handling of the user interface was a decisive criterion. “Simple operation is important for our customers, so that a smooth flow, in addition to a high-precision result, is guaranteed”, comments Gerd Schäfer, sales manager at MIKROMAT and the person responsible for the thread grinding application technology. Until 2009, MIKROMAT, just like the other industry giants, still ran on a DOS-based system, including the G-series grinding machines, because it was a proven operating system. However, this offered no future-proof use in the long run, as it was outdated and no longer able to run on today’s computer systems. “We therefore switched to a Windows-based system”, says Gerd Schäfer. “It is only thanks to this system that the common graphic user interface standards that exist today are achievable.” However, given the new generation of the system, MIKROMAT has also had to find a new and reliable control system. After all, grinding machines are required to meet especially high standards regarding dimensional accuracy and complexity. In order to meet the specified basic size and the required accuracy in the manufacturing process, and to prevent erroneous grinding processes, a clear and easy-to-understand control operation is required. However, the user interface of the new CNC technology is a major challenge for inexperienced users in particular as they need to be trained in how to use the machine first. For this reason, in order to ensure a quick and easy incorporation, MIKROMAT placed special emphasis on monitoring, whose user interface works via insertion in a drawing template. As many tools as possible have to be created and the user needs to find these understandable and easy to operate. Another important criterion was the implementation within an open system. Gerd Schäfer adds: “We have clients in various industries and with various requirements. With an open system, we can program the monitoring individually, according to our customers’ visions.” With these requirements for the new monitoring system, the search began for an appropriately potent supplier. The choice was control manufacturer Schleicher Electronic Berlin GmbH. A decisive criterion for the decision against large, well-known competitors was the open system which Schleicher can enable with its monitoring system XCA 1277. This is something which provides MIKROMAT with an enormous range of design freedoms: the user interface can be modelled on the drawings of the technologies with the end client. The control functions are thus precisely limited to its requirements. To date, no other controller manufacturer for thread grinding machines can offer such creativity freedom. In addition, the XCA 1277 is extremely easy to use: all grinding and access data can be easily inserted in the screens, without any need for programming skills. Any language barriers will be undermined by internationally understandable imagery. “Our grinding machines are used in Russia, China and Europe, but many of our end clients don’t speak English”, says Gerd Schäfer. “For this reason, we use graphics, and as little text as possible.” Schleicher Berlin GmbH Tel: 0049 30 330050 Email: [email protected] www.schleicher.berlin Grinding & Surface Finishing n SEPTEMBER 2015 29 GSF PRODUCTION GRINDING 22-31_ES CONTENTS 4-5 19/08/2015 14:33 Page 30 Production Grinding Customised CNC upgrade simplifies railcar axle grinding A comprehensive upgrade of classic high power centreless grinding machine tools is helping a leading railcar axle manufacturer to greatly simplify precision grinding operations on axle forgings. A key element of the project, which has been managed by APeC Integration Services, Inc, is the retrofit of the customised CNC control based on NUM’s powerful Flexium platform. Based in Wattsburg PA, APeC is an electrical systems integrator specialising in upgrading machine tools with modern PLC and CNC control systems. Established in 1989, the company has built a reputation for enabling clients to maximise the longevity and performance of their machine investments. Key retrofit services include upgrading servo and spindle motors and drives, PLC integration and custom machine controls, and complete CNC replacement. Extensive mechanical and electrical upgrades to this Landis centreless grinding machine include a new Flexium CNC system from NUM The machine tools in this particular project are high capacity Landis centreless grinders, which utilise a dressable grinding wheel and a plunge grinding cycle to create precision profiles on railcar axle journals. During grinding, both the axle workpiece and the grinding wheel rotate in the same direction, which means that the two surfaces are moving in opposite directions at the point of contact, resulting in smoother operation. Once the machine is up to speed, the grinding wheel is fed or ‘plunged’ into the workpiece and makes continuous contact with a single point along its length. The plunge action is controlled by a servo-driven axis grinding at several feed rates, with transition points monitored by in-process gauging. A built-in automated 2-axis dresser system with a diamond tipped tool is used to dress the grinding wheel whenever necessary. This is the second time that APeC has improved the performance of these grinders with control systems based on NUM CNC kernels. The original machines were hydraulically actuated and equipped with tracer type wheel dressing systems. In the mid 1990’s, APeC performed a full mechanical and electrical upgrade on each machine that included retrofitting a modern CNC system and in-process gauging instruments. On that occasion, the company based the upgrades on NUM’s Power 1060, which at the time was regarded as one of most flexible and user-friendly CNC systems on the market. After a further 20 years’ full-time service in a busy production environment, the machines became due for another mechanical and electrical upgrade. APeC had supported the machines and worked closely with their operators throughout this period, during which time it had also developed a number of ideas for making the machines even easier to operate and more productive. The upgrade program offered the ideal opportunity to put many of these ideas into practice. To expedite machine upgrade and minimise the impact on its customer’s production schedules, APeC managed a three-way development partnership. All major mechanical re-design, hydraulic, lubrication, and geometrical rebuilding aspects of the project were handled by EURO Machinery Specialists Inc, a company with some 45 years’ experience of refurbishing and modernising high value metal cutting machine tools. On the control side, APeC collaborated with NUM USA to develop a unique and intuitive human machine interface (HMI). This enables 30 Grinding & Surface Finishing n SEPTEMBER 2015 The machine’s plunge grinding cycle is controlled by a servomotor-driven axis, utilising feedback from a linear encode operators to learn how to use the machines very easily and quickly – even if they are unfamiliar with these types of grinders. Customer benefits include improved worker satisfaction, less need for training and increased machine productivity. Dave DeCoursey of APeC says: “A key project goal was simplifying machine operation as much as possible. NUM’s open Flexium CNC platform provides the control flexibility and HMI customisation facilities that we needed to develop individual, task-oriented screens. The user interface is consequently now much more ergonomic. Most operations, such as offset calculations, calibration, dressing and automatic grinding cycle initiation, are now performed using single, virtual pushbuttons that are only displayed when appropriate.” Each machine upgrade uses several NUM products, including the CNC kernel, touch-sensitive operator panel, servo drives and motors. The Flexium CNC system uses EtherCat I/O communications, making it GSF PRODUCTION GRINDING 22-31_ES CONTENTS 4-5 20/08/2015 15:25 Page 31 Production Grinding simple for APeC to implement an advanced plunge depth control architecture. The in-process gauging instrumentation previously used for this aspect of machine operation has been replaced by a linear encoder, which facilitates fast and accurate depth control, as well as providing real-time feedback to the operator throughout the grinding cycle. The main control screen features two large analog-style dials, supported by digital displays, which derive their input data from separate measurement probes located along the length of the axle journal, allowing the operator to monitor taper tolerance very easily. The client- and application-specific HMI software that APeC has developed for the grinding machine upgrade is task oriented. It uses individual screens that are tailored to the application, with clear context-sensitive functions that help to prevent human error. By using the Extended NCK Access (ENA) facilities of the Flexium CNC controller, each custom PLC-driven visualisation can control and monitor the CNC functions directly. This form of control approach is especially useful for automated teach-type functionality, such as guiding an operator through machine start-up and preparing for automatic cycles. For example, the start-up screen initially displays only the status of the CNC system and a single ‘Shutdown’ button. As soon as the CNC system indicates that it is ready, the start-up screen displays two additional buttons: Home Screen and Manual Operation. When the operator touches a displayed button and causes a change of screen, the software automatically alters the CNC mode accordingly and selects the corresponding part program if applicable. By confining the operator’s available options to just those that are appropriate at the time, the software helps to ensure consistent and efficient machine use. Another major advantage of this type of control approach, with extended access to the NCK, is that it can be used to help the operator with tool offsets and adjustments to part program dimensions. When the grinding wheel or dressing tool is replaced, the operator can manually position the tool on the desired surface of the wheel, access a password-protected screen and then simply press a button. The offsets are calculated and pushed into the dressing program automatically, using the ENA facility. This same facility allows the operator to alter During grinding, the main control screen displays two large analog-style dials which allow the operator to monitor the tolerance of axle taper very easily and accurately dressing dimensions and spark out set points simply by adjusting a value up or down. These are then pushed into the corresponding part program.

However, protecting grinding machines is the major application, with many of Kraft and Bauer’s fire extinguisher systems particularly being found protecting tool grinding machines from well known manufacturers such as Jones & Shipman, Walter, Schneeberger, Rollomatic, Haas, Saacke, Ewag, Vollmer, Anca and Schutte. There are now some 17,000 K&B systems protecting machine tools in Germany alone. Louise Boraston, MD of Kraft & Bauer UK explains why tool manufacturing and regrinding companies commonly face an increased risk of fires on their tool grinding machines: “Modern CNC tool grinding machines commonly have at least five CNC axes that interpolate all at the same time to generate the ever more highly complex forms that are needed in the design of today’s cutting tools. In terms of programming alone, this need for special form grinding means that the manufacture and regrinding of cutters is one of the most complex disciplines that production engineers face. “All of the leading tool grinding machine manufacturers have developed software packages that make programming both faster and easier than ever before. However, the room for operator or programming error remains high. For example by making a small error in inputting data to the grinding wheel specification page or tool length and/or diameter entry can easily cause a collision between the wheel and tool during grinding, or result in a very heavy cut taking place, either of which will cause an enormous amount of heat to build up within seconds. “There are also many other ways in which unwanted intense heat can be generated during tool grinding, such as coolant failure or more commonly coolant not quite being directed to exactly the right point as the grinding position changes during complex grinding cycles. With solid carbide cutters demanding the use of oil as a coolant during grinding, as opposed to water based emulsion that can be used for other grinding tasks, this combined with the risk of heat being generated means that there is an ever present and real risk of fire on CNC tool grinding Machines. The 5-axis movements of the grinding head and workhead and use of higher pressure coolant generates a lot of oil mist that even with the fitment of suitable electrostatic mist extraction equipment means that the machine cabinet is, during the grinding process, full of oil mist vapour and a single grinding spark will easily ignite that leading to a major health and safety risk. “There is seemingly no pattern to the occurrences of fire on CNC tool grinding machines, although obviously the more machines in use and the more hours they are ran for vastly increases the risk for any particular user. The trend for automated production using autoload/unload systems increases the threat still further and the part or total absence of operators who would otherwise be able to intervene in the event of an incident further compounds the problems. We have customers with one or two machines that have never had fire incidents, but equally have others who experience several every year, then none for a long time, and then again have a major problem. Accidents are accidents and cannot be forecasted but when companies carry out risk analysis on production machines it’s usually tool grinding machines that head up that list! “To protect their customer’s investments, leading machine tool companies such as Walter, Schneeberger and Rollomatic, to 32 Grinding & Surface Finishing n SEPTEMBER 2015 name just three, fit our systems as standard and each year Kraft & Bauer sell well over 750 fire protection systems to tool grinding machine manufacturers alone. However afterwards many end users do not consider the servicing of the fire systems and we regularly come across systems that have not, for a variety of reasons, been functioning correctly for some time. Believe it or not we actually find several every year that whilst functioning correctly have previously been used but have not been refilled with CO2. “Some of the UK’s leading tool grinding companies are very much health and safety conscious and protect their workers and indeed their business’s by ensuring that their tool grinding machines are well serviced with a high degree of fire protection but many others are simply taking huge gambles by not doing so. “Many grinding machine users believe that the automatic fire prevention systems are serviced by the machine tool manufacturer’s engineers along with a regular annual routine machine service. However, this is simply not true. Our systems must be serviced by us and if grinding machine end users are not in possession of a validated K&B certificate that demonstrates the systems have been serviced in accordance with our procedures then any insurance policy that is in place is almost certainly going to be invalid in case of a fire incident. GSF MACHINE SAFETY 32-33_ES CONTENTS 4-5 19/08/2015 14:34 Page 33 Machine Safety “Other machine users rely upon independent fire extinguisher companies to service machine tool fire systems, but these services are almost always limited to simply weighing the bottle to see if it is full and no independent UK based service companies have received the necessary training and are simply not authorised to service our systems. These companies are used to looking after simple hand held fire extinguishers of the type that is used to protect offices and all end users are warned to be sure the correct procedure are being followed. “These companies are leaving themselves wide open to legal action in the event that the mandatory H&S laws are not being followed, with fire risk assessments being carried out and preventions not only being put into place but also subsequently being routinely checked by validated and fully certified experts. Often engineering companies don’t take into account the affect of a single fire on a machine can have on production and that it is not only highly dangerous to operators it can also easily result in the loss of the machine, a complete production line, or even the entire factory. Users need to ask themselves if, with new tool grinding machine build times being between 6 and 12 months, their customers would still be around when machines damaged by fire, although possibly insured, can subsequently be replaced. “Anyone thinking machine tool fires are a low risk occurrence that rarely happens, needs to think again. Last year there was at least one fire incident every week on grinding machines in the UK and these are only the ones that we know about, as the fires were prevented from leading to extensive damage or loss of life by our systems.” Kraft & Bauer only manufactures specialist systems for machine tools, all of which are IP55 certified against ingress of coolant, and offers various options, including fire detection via Infra Red (IR) temperature radiation detectors and Ultra Violet (UV) sensors, as well as the most basic of usual temperature based detection. CO² (or Argon) bottles of various sizes from 2 kg to 20 Kg may be fitted, although for the very largest of machine tools more than one can be used to ensure total protection. Initial detection and automatic activation of the fire security systems is catered for by IR or UV sensors, or in some cases a combination of both, with instant reaction times of under a second being possible. In the case of the fastest UV radiation sensors that operate within a wave range of 185-260 nm, a short activation check of between 1-2 seconds is usually set to avoid systems being accidentally set off by flash-light photography etc. Automatic secondary backup fire detection is then catered for by temperature sensors set to between 30 and 140 degrees that are integrated into the machine cabinets; usually adjacent to a mist extraction point that would draw flames in the event of a fire. A further final means of detection is visual by an operator and manual system activation is always possible by using emergency button switches mounted to the front of the machines or by pulling the emergency toggle pins mounted onto the systems themselves. When a fire is detected the machine tool is automatically shut down and the fire extinguished before any major damage can occur. Warning to operators is taken care of by both high powered 125 db acoustic sirens and high visibility warning lights mounted on the top of the machine. It is often the case that machines can be back in action within minutes of an incident occurring. The latest micro-processor technology is employed, along with self contained emergency power supply back-up devices to ensure that even in the event of loss of electrical power the fire protection systems can still function. A further recent development is the use of fully automated CO2 cylinder check systems to ensure that machines cannot be ran if a bottle is empty. Kraft & Bauer UK offer a full sales, service and installation facility from their base in Coventry and systems can be fitted to new machine tools or to any existing machine of any type as a full retrofit service is also offered.

A private limited company, GB Precision recently celebrated its 40th anniversary, no mean achievement in today’s highly competitive world, and the direct result of the company’s on-going strategy of investing in the very best technology to meet its customers’ increasing demands in terms of accuracy and precision. Director Paul Turner explains: “We are constantly looking for new ways of improving our productivity and capabilities. This often results in the development of new procedures or methods of working to meet specific engineering challenges. In other words, genuinely thinking “outside the box” to achieve meet our customers’ requirements. “We aim to get the absolute maximum from our machining technology, not only by achieving the best performance from each particular machine, but by using technology in the optimum way for each job. What’s more, we further increase productivity through our investment in an off-line, presetting and palletisation system which enables us to reduce setting times, increase machine utilisation, achieve better surface finishes and increase reliability.” The company’s recently extended, purpose-built 8000 sq ft facility houses a range of the latest CNC machining technology. However, the cornerstone of the company’s activities remains its precision grinding capabilities, with no less than three CNC Studer machines, two S21s and an S31, making GB Precision one of only a handful of companies in the UK with the capability of offering out-of-round grinding. These Studer machines have the ability to grind high-accuracy, bespoke thread forms, which can be required for top-end mould tool assembly work, as well as to cut tapered polygons on the end of otherwise cylindrical geometric forms. They also handle the whole range of high-precision grinding tasks, including the creation of external and internal spherical forms, where the surface finish across the whole part, and the form accuracy, is of critical importance. Naturally, to help ensure the quality of its subcontract work and to obtain maximum productivity, GB Precision’s investment in the best technology is matched by its use of the best grinding consumables, which is why the company has for many years purchased 3M Winterthur high-accuracy grinding wheels. Paul Turner explains: “For us, the most important thing is the adaptability of the 3M Winterthur wheels, which means that we can rationalise the number of wheel grades we keep on the shelf. Being a subcontract company, we have to grind whatever the customer gives us, from stainless steels, toughened steels, surface-treated, for example nitride, through to hardened tool steels, and we find these wheels give us really good grinding performance across the board. “We have been using 3M Winterthur wheels for getting on for 13 years, since we bought our first Studer in fact. That machine was delivered with 3M Winterthur wheels, which we used very successfully. When those wheels needed replacing, we originally reverted to the wheels we had been using on our manual machines. They proved to be quite inadequate for the job and we have been buying 3M Winterthur ever since.” “We dress accurate, small, complex forms into our wheels and in our experience they hold the form extremely well, without wear 34 Grinding & Surface Finishing n SEPTEMBER 2015 at the edges. We find they give us a stable process capability, so that we can reliably repeat a process and achieve exactly the same, correct size as on previous parts, a vital benefit to us and our customers. Mike Denton, national sales manager for 3M Abrasives Sytems Division, Precision Grinding & Finishing, concludes: “Given its demanding quality requirements, GB Precision makes use of the premium 54A grinding wheel range from 3M Winterthur. The high quality wheel range includes grades designed for OD and ID cylindrical grinding, surface and profile grinding and gear grinding, across materials including soft steel, hardened steel, case hardened steel and Inconel. “In addition to providing excellent surface finish characteristics, 54A grinding wheels help to ensure the efficiency of GB Precision’s grinding operations as they exhibit exceptional flexibility and outstanding stock removal capabilities. 3M Winterthur UK Tel: 0114 243 7180 Email: [email protected] www.winterthurtechnology.com KREBS & RIEDEL Schleifscheibenfabrik GmbH & Co.

One area where Krebs & Riedel excels in is the supply of very special wheels for gear and thread grinding applications and special wheels are available to suit machines manufactured by Gleason-Pfauter, Oerlikon, Kapp- Niles, Hofler, Maag, Samputensili and Reishauer etc. Krebs is also a member of the “Gear Research Circle” at Aachen University and is heavily involved in developing advanced wheels for the latest production technologies employed by leaders in the field of gear manufacture. For specially profiled wheels for gear production Krebs keeps customers blank wheels in stock and upon order will profile these to suit and then supply within just 2 days. Advanced Grinding is able to supply wheels in large quantities at pre-decided call off times for next day supply from its base in Coventry, but equally is supplying its UK gear manufacturing customers with just a single specialist wheel to suit a specific grinding task that they have, as well as supplying wheels pre-profiled to any desired form. Krebs & Riedel is just completing the installation of further kilns that will increase production and throughput times allowing it to decrease usual delivery times from around seven to eight weeks to around five weeks, although many standard wheels are available “off the shelf”. The newly developed V86 and V87 bonding systems are the latest addition to the highly successful V84 and V85 from the MULTO line. The new low-fired bonding system allows increased processing speeds (vc = 80 m/s) and optimum grain bonding at high or very high porosity gives an increased wheel life time without thermal damage to peripheral zones. The low bond share (due to cool grinding) results in less abrasion of the dressing tool. The Multo Pink classic V84 bonding system remains the best seller as a more universal grinding wheel for a wide spectrum of grinding applications, while the Multo blue V85 system with sintered aluminium oxide is used for increased metal removal rates for faster cycle times on demanding materials. Meanwhile, the Multo Green V86 grade has been developed for external cylindrical angular plunge grinding when the grinding wheel must work under light pressure. The use of this wheel is proven at speeds in excess of 63 m/sec. The final new development to the Krebs & Riedel range of Multo wheels is the Multo Yellow V87 wheels that offer increased retention of the wheels form when very high wheel porosity is also called for at the same time. To reduce dressing tool wear sintered micro crystalline aluminium oxide is not used for this particular wheel. As a manufacturer of conventional, CBN and diamond and ceramic bonded wheels Krebs & Riedl has observed an increasing trend for several years towards dressable, ultra-hard grinding wheels. New materials such as powder metallurgy steels as well as very strong spray-on materials take conventional grinding agents to the limits of their performance and the range of demanded part tolerances is also getting ever tighter. At the same time machine production times and down time should be reduced and here extremely hard CBN and diamond grinding agents offer significantly more potential to reduce production costs. The substrate of a grinding wheel is also an essential building block in the grinding wheel system and substrates made of fibre-reinforced composite materials do offer advantages for special applications. Apart from reducing the weight by up to 70 percent, they provide good damping while providing a very strong substrate. Krebs and Riedel are pioneering the use of carbon fibre wheel hubs and tests have shown significantly faster cycle times are obtained as well as improvements in surface finishes generated by these special types of grinding wheel. It is developing new wheels all the time and they are added to the existing collection of over 60,000 different wheel types already available. As Krebs & Riedel gears up its support for its growing UK customer base that’s become an important marker for them it’s announced its commitment to again exhibit at the MACH 2016 exhibition on the AGS stand.

DRONCO becomes an integral part of Jason Finishing Group, a Jason business unit and the leading global producer of technical and maintenance brushes, polishing tools and compounds. The Jason Finishing Group portfolio includes well-recognised brands such as Osborn, the only truly global player in the industrial brush and polishing market, JacksonLea, Lippert-Unipol and Sealeze. The deal allows Jason Finishing Group to enter a targeted and faster growing $6 billion abrasives market segment and solidifies the company's position as the complete surface treatment and finishing solutions provider. DRONCO's full range, which includes cutting, grinding and abrasive discs, diamond tools, ceramic abrasives, sandpapers and technical brushes, is the ideal complement to Jason Finishing Group's product portfiolio. The acquisition opens Jason Finishing Group products to customers and distribution channels where it currently has a limited presence, while allowing the company to become a "one-stop shop" within the finishing industry. Under its new ownership, DRONCO will be positioned for continued growth. DRONCO products will be immediately embedded into Jason Finishing Group's well-established, global sales and logistics network, thereby making the DRONCO line available to a much broader market. Geographically, DRONCO's strong product portfolio will be distributed to global markets, with a focus on further expansion in Europe and North America. To support North American sales growth, logistics and distribution of DRONCO products will be added at Jason Finishing Group's Richmond, Indiana facility by the end of 2015. In 2016, DRONCO will be expanded into emerging markets to meet increased demand for abrasives in developing and growing economies. "DRONCO is an outstanding strategic fit for our organisation and we are excited to welcome the company and its employees into the Jason family," says David Westgate, chief executive officer at Jason. "With DRONCO in our portfolio, we reinforce Jason Finishing Group's status as the leader in finishing. Our customers will benefit from access to DRONCO's line of quality products, while those of DRONCO will benefit from the availability of Jason Finishing Group's extensive line of brushes and polishing tools from brands they recognise and may already trust for their surface treatment and finishing needs." "By leveraging the numerous inherent synergies between DRONCO and Jason Finishing Group brands, like Osborn, we expect to achieve considerable long-term growth that will benefit each company in our portfolio," says Dr. Florestan von Boxberg, president of Jason Finishing Group. "DRONCO has earned a privileged reputation as an innovative, well-run company that produces high-quality products. We are proud to add this organisation to our portfolio and are excited about the value this acquisition brings to our joint customers." Jason intends to maintain DRONCO's Wunsiedel, Germany site as the primary manufacturing and R&D centre for bonded products. In addition to this site, DRONCO has three subsidiaries in UK, Sweden and France. Jason Finishing Group has therefore acquired a global abrasives company that is recognised for quality and product innovation. In fact, DRONCO recently introduced a next-generation line of cutting and grinding discs with a lifespan that is three times that of its counterparts. Through the acquisition of DRONCO, Jason Finishing Group expects there to be a sharing of technologies that will lead to the development of innovative new products for Osborn and other brands within the Jason Finishing Group portfolio. DRONCO is one of Europe's leading manufacturers of abrasives and sells its products in approximately 100 countries. The company's range of products, including cutting, grinding and abrasive discs, diamond cutting tools and ceramic abrasives, is recognised for outstanding quality among professional tradespeople and discerning DIY users alike.

Set over 45 acres and with over 600 employees covering three shifts, the company is constantly working to update its processes and take advantage of the latest technologies to optimise its output. So how do you ensure your processes are being completed as efficiently as possible in a fast-paced environment where priorities can change in an instant? Principal buyer John Anderson says: “The foundry will always try to sell up to capacity and take orders which will often need to be fulfilled at short notice. This means our suppliers need to adopt a pro-active and totally flexible approach.” Special Metals Wiggin supply a range nickel-based alloys to a number of industries from aerospace and automotive to oil, gas, petrochemical and medical; in fact any industry which requires nickel alloy. In 2009 a decision was made to try to consolidate suppliers and streamline the supply chain, thereby optimising processes and ultimately reducing costs. The first area the company targeted was the supply of abrasives on site. In 2009 abrasives were supplied by five manufacturers and a number of distributors in order to fulfil the requirements of a challenging environment. Manufacturers were invited to review the cut-off and grinding applications on site and to put forward a proposal to supply abrasives on an on-going basis. One of these manufacturers was TYROLIT, a supplier of abrasive products and technical support services across the world. TYROLIT application engineer Paul Carson and two colleagues from TYROLIT’s headquarters in Austria visited Special Metals Wiggin to begin the process of reviewing the cut-off, and grinding applications. Paul Carson says: “The first application we looked at was the chopping of 80 mm solid bar. The company was using a competitor’s wheel to cut the bars which was causing cracks and discolouration which ultimately caused a shell like appearance in the heat effected zone”. TYROLIT introduced its SECUR range of wheels, which proved a cost-effective alternative to the competitor’s wheels. The results were very favourable. John Anderson comments: “Once we changed to TYROLIT’s cut-off wheels we had no more burrs or blueing. The discs also cut quickly and neatly and they’re so effective the factory cuts two bars together at the same time.” This ultimately halved process time and doubled capacity on one machine. The next application to be reviewed was a tube reducing line. Rubber bonded wheels were being used to cut tubes and bars causing severe problems with smell, sharp burrs and resin deposited on the cut edges and inside the tube. Coupled with supplier inconsistency and poor lead times for supply, the process was in urgent need of an over-haul. Paul Carson looked at the process and introduced a TYROLIT resinoid wheel from the company’s SECUR range: “The wheel cut with no burrs and no smell, while the elimination of resin deposits means that there was no ingress of dirt in to the tubes and secondary work like filing the burrs off and manual buffing has reduced significantly. Our wheels were marginally more expensive than the previous supplier’s products. However the overall cost-per-cut was greatly reduced.” TYROLIT then moved on to look at other applications which could be improved. Wheels were trialled with the aim of reducing cost-per-cut or per-part. Paul Carson continues: “We basically moved through the factory to different cells to look at each process in turn. We slowly built up trust and goodwill with the personnel on the shop floor and based on their positive experience with Tyrolit, they recommended us to other departments. Over the next five years we reviewed the majority of cutting & 40 Grinding & Surface Finishing n SEPTEMBER 2015 grinding processes on site and were able to improve each one using TYROLIT wheels.” TYROLIT has been supplying Special Metals Wiggin since 1976. In 2009 its share of the abrasives business with the company was between 15 and 20 percent. Now it’s around 80 to 85 percent. It supplies the TYROLIT range of grinding wheels for every grinding process on site and the vast majority of cut-off wheels. So why is the partnership so successful? John Anderson is convinced it’s the all-round partnership approach: “TYROLIT are responsible for managing supply of wheels to us but they are also pro-active on site as a whole, looking at processes and where things can be improved. They have a pro-active presence which helps us to keep improving on what we’re doing.” A comprehensive stock arrangement is also in place to ensure smooth supply of GSF GWD 34-43_ES CONTENTS 4-5 24/08/2015 10:58 Page 41 Grinding Wheels & Discs wheels. Stock is held on-site in Hereford and also at TYROLIT’s warehouse in Northamptonshire and stock levels are reviewed weekly. John Anderson says: “We keep around a month’s stock here in the foundry but we can call stock from TYROLIT whenever we need to. The arrangement works very well indeed.” The next task for Paul and TYROLIT is to look at the supply of hot pressed wheels and how new technology may be able to provide an advantage. John Anderson says: “Our relationship with TYROLIT has definitely improved things. Rationalisation of the supply chain has made things easier and because of our stock arrangement we get what we need quickly. It’s excellent having someone with technical awareness on-site and TYROLIT’s product development is very good. They have built a total resource centre and are supplier of choice for the majority of our applications. Although we operate an open-door policy for trials, it’s only open to suppliers we know and trust so we invite Paul and TYROLIT to review our applications and see how continued development can improve things.” Ultimately, consolidation of the supply chain has benefited Special Metals Wiggin in a number of key areas: supply lead times have been reduced, cost-per-part is lower and time is saved for both the shop floor and buyers thanks to comprehensive procedures and stock arrangements, all the result of a relationship built over 39 years.

Due to continuously increasing demands for product quality, precision and surface finishing with simultaneously rising cost pressure, companies are facing new challenges to an ever greater extent. DeburringEXPO will present innovative solutions for meeting these challenges at the Karlsruhe Exhibition Centre from the 13th through the 15th of October, 2015. The exhibitor list for the deburring and polishing trade fair already includes more than 70 exhibitors from eight countries (status as of 25 June 2015). The supplementary expert forum additionally offers a great deal of valuable knowledge. Whether parts are manufactured by means of machining, metal forming or master forming, deburring, rounding and polishing don’t usually belong to the core competencies of manufacturing companies from the fields of automotive, aviation, medical technology, machinery manufacturing, drive technology, precision engineering, microsystems technology, casting, hydraulics and other industry sectors. However, in order to fulfil today’s typically exacting demands placed on product quality, functionality and service life, undesired “production remnants” have to be removed. In particular, deburring processes are still frequently executed just like they were in days of old, with all of the associated disadvantages including a lack of reproducibility and high costs. Companies are therefore on the lookout for efficient and innovative solutions for deburring, rounding and polishing. These can all be found at DeburringEXPO. This is substantiated by the exhibitor list for the technical trade fair for deburring and polishing technology which already includes more than 70 companies. “Positive feedback, coming from companies outside of Germany as well, is confirming our concept for an independent trade fair aligned to the fields of deburring, rounding and polishing”, stresses Hartmut Herdin, managing director of event promoters fairXperts GmbH & Co. KG. There’s plenty of visitor interest in the new trade fair too. “An initial mailing to potential expert visitors also resulted in excellent feedback. In addition to market leaders from the automobile industry, automation technology, drive and transmission technology, aviation, machinery manufacturing, mechanical engineering, the sanitary industry, clock making and the tooling industry, numerous highly capable suppliers for various other industry sectors have already announced that they will visit the trade fair”, adds Hartmut Herdin. Innovative solutions for enhanced value creation and a sharper competitive edge Numerous market and technology leaders are already amongst DeburringEXPO’s exhibitors. This ensures that comprehensive, representative offerings for deburring, rounding and polishing processes and technologies will await the visitors. These will encompass various innovative processes and further developments which not only 44 Grinding & Surface Finishing n SEPTEMBER 2015 GSF DEBURRING 44-49_ES CONTENTS 4-5 19/08/2015 14:39 Page 45 assure the fulfilment of current requirements for process reliability and economic efficiency. Depending on the utilised technology, they also make it possible to furnish processed surfaces with special characteristics. Amongst others, these include reduced friction and wear, minimised noise levels, increased internal compressive stress, longer service life and energy savings. Issues covered by DeburringEXPO which also address the areas of product development and design engineering include burr avoidance and minimisation, as well as burr-free production of contours, structures and even non-cylindrical drill holes. The deburring, rounding and polishing production steps can thus contribute to enhanced value creation as well as a sharper competitive edge. Expert Forum – value added through knowledge and an exchange of experience Exhibitor offerings presented at DeburringEXPO will be complemented by an integrated expert forum. A practically oriented transfer of knowledge concerning deburring and polishing technologies, as well as examples of best practice and a direct exchange of experience, will be the centre of attention. This will make it possible for visitors to gather targeted information on various issues in the field of deburring and polishing technology. The DeburringEXPO exhibition offering covers equipment, systems and tools for belt grinding, brushing, abrasive flow machining, vibratory grinding, blasting with solid and liquid media such as high pressure water jets and CO2 snow jets, abrasive water-jet blasting, magnetic-abrasive deburring, ultrasonic deburring, chemical bath deburring, electrochemical machining (ECM), precision electrochemical machining (PECM), electron beam machining, thermal energy machining (TEM), mechanical deburring, buffing, polish honing, electrolytic polishing, plasma polishing, laser polishing, immersion and brush polishing, as well as measuring, test and analysis systems, deburring, rounding and polishing in the form of services, research, training and literature.

However, Ellesco is clearly bucking this seasonal trend with four Timesavers-Grindingmaster rotary brush machines installed in the last couple of weeks. The popularity of the Timesavers-Grindingmaster 42 Series WRb and Rb surface finishing, deburring and edge radiussing machines has soared in recent months with sales across the length and breadth of the UK. The most recent installations have been made at Had-Fab Ltd in East Lothian, Bridmet Ltd in Bridport, Dorset, Welland Power Ltd in Lincolnshire and Syspal Ltd in Brosely, Shropshire. All these manufacturers are new customers to Ellesco and the Timesavers-Grindingmaster brand. Commenting on the surge in orders, Ellesco managing director, Guy Newton says: "Each of these new customers is manufacturing completely different products from a variety of materials for very diverse industry sectors. These applications range from heavy duty surface finishing with 40 grit abrasive belts through to the polishing of laser cut sheet metal and even the fine graining of wide sheet stainless steel for the production of toilets, basins and cooking equipment in the hygiene and catering sectors. Whilst these customers specified the 42 Series WRb and Rb machines for edge radiussing, two customers specified the Timesavers-Grindingmaster 42 Series for deburring and surface finishing, such is the capability scope of the machines." A Common Goal The one thing all these new customers have in common is the desire to improve productivity, quality and consistency whilst reducing costs. Guy Newton continues: "All of these customers were previously finishing parts by hand and were to an extent unaware of the entire capabilities and benefits offered by the Timesavers-Grindingmaster range. By reducing, and in some instances eliminating, hand finishing, these customers are obtaining greater throughput, reduced lead times and above all a consistent surface and edge finish. This is resulting in improved quality of the finished components and also a reduction in reject rates. "In addition, the easy-to-use Timesavers-Grindingmaster machines and Ellesco’s team of nationwide service & commissioning engineers, ensure immediate operational benefits and support. They can then swiftly run a batch of components through the WRb or Rb machine in a fraction of the time of hand finishing. This is freeing up man hours for the end user. What's more, we are witnessing more employers becoming aware of the latest Health & Safety 'trigger directive'. The key to this new directive is that no employee should be using hand tools for more than 1.5 hours a day, to restrict the potential for RSI. Employers conscious of employee health & safety are instigating change in line with the regulations and Ellesco has just the answer with the Timesavers-Grindingmaster range of deburring, edge & surface finishing machines."

The successful AC microLine® product line, with its applications in fine grinding, polishing, lapping and honing, is now complemented with the application of double-side brush deburring. Most conventional linear brush deburring machines have the disadvantage of an expensive flip-over device with high space requirement, particularly for non-magnetic work pieces. The AC microLine deburring machines, however, process simultaneously both surfaces of the workpieces in one production step. Thus, no expensive flip-over devices are necessary which leads to significant cost savings and a smaller footprint of the system. Furthermore, the magnetisation and de-magnetisation for magnetic workpieces is not necessary anymore. With an AC double-side deburring machine, the workpieces are transported in workpiece carriers, so that batch machining can take place. The planetary kinematics of brush wheel, pin ring and work piece carrier rotation enable a steady and high quality of deburring and edge rounding. This is ensured because of the movement of the work pieces in epicycloid and hypocycloid trajectories. Customer benefits with AC microLine deburring machines include: double-side brush deburring in one production step without the need of flip-over device; significant smaller space requirement compared to conventional deburring systems with flip-over device; suitable for non-magnetic workpieces; reliable Peter Wolters AC microLine technology; easy automatic interlinking of an AC microLine fine grinding machine and deburring machine in the same size, because both machines are equipped with the same epicyclic workholder drive system; handling of the workpiece carriers; conversion to an AC microLine fine grinding machine possible; outstanding synergy with other Lapmaster Wolters machines: e.g. high-precision double-sided grinding and deburring machines. There exists a high amount of different brush deburring wheel specifications. For every customer application, Lapmaster Wolters will design and specify the brush deburring wheels according to the specific customer requirement for its workpiece range.

One such challenge is the method of deburring. A process that is typically defined by removing a ‘burr,’i.e. a raised edge of excess material or area of roughness produced in cutting or shaping of metal, which is carried out by chamfering the edge of the metal to create two smaller sharp edges. The intricacy of the part coupled with demanding material properties are both key obstacles that can make it difficult to find a deburring method that is efficient, both in terms of cost and process. Most surface finishers carrying out a deburring process, whether it be in a pattern/tool makers or in an aerospace manufacturing workshop, are looking for precise edge finishing with increased speed and reduced side effects. For example some manufacturers will require a deburring process to be completed in a specific timeframe, such as CNC machines which need the mechanical parts to be deburred in the cycle time specified to match the overall production line rate, and others will be more focused on the precision and geometry. One example would be turbine blades where it is critical that the manufacturers produce a specific deburred radius. Deburring can be required wherever there is turning, milling, drilling, boring, lapping, shaping, machining, surface grinding and abrading. All these machining and cutting operations produce a burr. It is the process of completely removing the burrs from a workpiece, leaving a slightly radiused edge, without any modification to the part shape and geometry. There are many reasons why deburring is necessary, not least for safety. When a piece of metal is cut in a workshop, the sharp edge can present a danger of injury. If the stainless steel used to manufacture tanks and vessels, professional kitchens or other food and beverage equipment is being cut to shape from a larger section then this can cause a burr on the underside of the material. The sharpness also predominantly poses a material handling risk as well as the end-product safety for the user. Additionally it can cause mechanical damage to the assembly if a burr breaks, for example on pistons, gears, textile machinery or computer hardware. Again, in the assembly of gears or parts in the power generation industry, they may not fit together if the burr is still intact. It can also be an important factor in maintaining a product’s aesthetic appearance, such as the front panel of radios, DVD players, furniture cabinets or building equipment. Finally, it can play a major role in electrical applications where a broken burr could create a short circuit in printed circuits, electric motors or generators. What are the options? Deburring is an ancient practice but its process has evolved throughout history, therefore there is a plethora of traditional methods available including: files; mounted points; bonded wheels; scalpels; abrasive rolls; wire brushes; abrasive belts; rotary burrs; flexi hones and rubber wheels. However, it is a solution for an absolute deburr that many manufacturers seek. At 3M, we have developed a variety of 48 Grinding & Surface Finishing n SEPTEMBER 2015 abrasive solutions for deburring that ensure increase efficiency and productivity in all metal and wood applications. For example, Scotch-Brite Products leave a much smoother surface after deburring and there is no undercutting or gouging of the surface. Unlike most other products, they also deburr both the sides and surfaces of the workpiece. Scotch-Brite Deburring Wheels and Scotch-Brite Radial Bristle Brush create an ideal deburr with a rounded edge as there is no secondary burr created by the process, the corners are rounded, there are no geometric changes and it keeps the tolerance. Let’s take a look at some of the traditional methods compared with the new technology incorporated in the Scotch-Brite Deburring Products: Using hand files and wire brushes on a buffing stand can provide results that are inconsistent and time consuming. Should a workshop or production line receive an increase in orders, another method would be required. Furthermore, coated belts can generate flats and change the geometry of the workpiece as well as leaving secondary burrs. Scotch-Brite Deburring Wheels and GSF DEBURRING 44-49_ES CONTENTS 4-5 19/08/2015 14:41 Page 49 Scotch-Brite Bristle Brushes by 3M overcome these issues as they help prevent undercutting and gouging through their controlled abrasive action. They last longer and are easier to use which means less downtime and operator fatigue, offering a more consistent, controlled result and they work much faster. They also offer a better alternative to wire brushes because there are no flying wires, making them far safer. Selecting a deburr based on application Heavier deburring Some applications require a heavier deburring tool where the nature of the material or the type of cutting tool produces a heavier burr than normal. Unitised wheels such as Scotch-Brite Wheels offer non-directional, soft deburring without making a large radius. An additional benefit to using this method is that the wheels can be used on any metal. However, they have a shorter life and lower cut than convolute or moulded wheels so are best suited for larger burrs where more aggression is needed. The Scotch-Brite Unitised Wheels by 3M are made from a non-woven web interspersed with resin and mineral, which is then cured under pressure to form a slab from which the wheels are cut. Lighter deburring For lighter burrs convolute wheels offer a better solution than the unitised wheels mentioned above. Convolute wheels are wound onto a fibreglass core with a resin layer to form a “bun” which is then cured in the oven. This offers a finer cut, softer density and a more even finish. Brushes by 3M more efficient. Generally speaking, the finer more conformable bristle products are used for decorative finishing they will conform more readily to surface contours along with generating a more uniform finish. The coarser less conformable bristle products are therefore used for more difficult blending, cleaning, and deburring operations. Pressure and speed can also influence product life as well as performance. Lower pressure and speed means a lower cut and longer life and higher pressure and speed means a higher cut and shorter life. Too-high a pressure increases wear drastically. When used in automated processes, lubricants or coolants are advised whenever possible to reduce heat and extend product life. All Scotch-Brite Products can be used with coolants such as water and some water-soluble oils - most reduce surface Stock removal and shaping A replacement for rubber bonded wheels is moulded wheels, suitable for stock removal and shaping. For example they would be used to remove milling marks and taking out small mismatches from the machining process. They are more aggressive than unitised wheels and run more smoothly than rubber and bonded wheels with the result that they can produce the result more quickly with less vibration. Light deburring, cleaning and surface preparation Bristle brushes offer the most effective solution for applications such as cleaning rust and contamination in maintenance repair and operation (MRO), removing coatings such as painted surfaces, weld cleaning, deburring complex shapes such as gears and turbine blade roots, and cleaning and/or deburring of threaded bolts. The Scotch-Brite Bristle Brushes by 3M are designed to offer additional safety benefits due to the abrasive-filled plastic brushes eliminating the risk of flying wires and conforming to contoured parts. Compared to wire or filament brushes, they can cut faster and more effectively meaning an overall increased production rate. The fresh mineral is exposed as it wears meaning there is a constant cut rather than the peening effect produced by the other products, making Scotch-Brite Bristle roughness. The higher viscosity lubricants produce lower surface roughness and grease produces a finer surface finish than oil. Whether it be to match a prodution line rate, or find a more cost-effective method that offers an absolute deburr, choosing the right method or tool and matching it with the right abrasive product is absolutely critical.

As designers of complete lapping solutions, Engis completely understands the importance of each component in the system and firmly believes that one of the best ways of maximising the efficiency of the lapping operation is the selection of the appropriate lapping plate and its ongoing care and maintenance. For each application there is an optimum lapping plate; for example for aggressive stock removal, composite iron plates, often used as an alternative to cast iron plates, provide excellent flatness, longer service life and refined surface finishes, particularly on metals and ceramics. For moderate stock removal one option is the use of composite tin plates which offer a lead-free working environment and provide superior surface finish, while working with coarser diamond slurries for fast stock removal, long service life and low reconditioning requirements. An alternative would be Engis widely used Hyprez HY copper plate, suitable for lapping virtually any solid material and which minimises fracturing and chipping tendencies when lapping crystal components. On the other hand, for applications requiring very low stock removal a tin-antimony plate may provide the best answer, being resistant to temperature variations during lapping and also preventing changes in lubricant viscosity during continuous lapping. Whichever plate is selected, the key to achieving good surface finish and flatness relies on its correct maintenance. The cleanliness, flatness and texture of the lapping plate directly affects the process results. It is important that plates are cleaned at appropriate intervals by rinsing them, Engis recommends using DI water, and using a squeegee and vacuuming away the excess residue, taking care not to introduce contamination to the plate during the process. Lapping plate flatness is of course also critical. If a lap plate is excessively concave, the parts will be convex and vice-versa. It is important therefore to periodically check plate flatness and make necessary adjustments. As a general rule a good starting point is a slightly concave plate (2.5 – 5.00 microns). During the lapping cycle itself, the use of ceramic conditioning rings is recommended. If the lapping plate starts to become concave, the conditioning ring should be positioned towards the outer edge and conversely, if the plate starts to become convex, the ceramic conditioning rings should be positioned towards the centre. 50 Grinding & Surface Finishing n SEPTEMBER 2015 If the lapping plate is out of flat and/or has lost texture, it should be re-conditioned. Engis recommends that, for composite lapping plates, a diamond plated conditioning ring (PCR) is placed in one of the roller yokes, while for cast iron or pure metal plates, a cast iron conditioning ring and a non-diamond abrasive such as aluminium oxide should be used. The ring should overlap both the ID and the OD of the lapping plate to ensure that a ridge is not formed during conditioning; the plate should be sprayed with enough lubricant to keep it wet and it is also important to use lubricant throughout the re-conditioning cycle. To correct the flatness of a plate that is too concave, the PCR should be positioned toward the OD of the plate and to correct a plate that is too convex, the PCR should be positioned toward the ID of the plate. Bear in mind that it is much easier to make a plate more convex than to make it more concave and for this reason it is important not to let a plate become too convex.

One disadvantage has been reliability, which gave Anopol cause to seek out a machine which was robust, extremely reliable and, importantly, straight forward to use. For these reasons, Anopol chose to add the Cougartron machines to its range of products for cleaning weld oxide discolouration from stainless steel. The company has long been marketing its Weldkleen and Minikleen units for cleaning welds. These machines operate by pumping a cleaning fluid to a pad at the end of a touch. The electrochemical action between the pad and the fluid produces an electrochemical action, which in turn removes the weld burn (oxide) from TIG welded seams and joints. Whilst operating, there is a continuous flow of solution to the pad. The operating principle for the Cougartron range of weld cleaners is rather different. Instead of a pad, a carbon fibre brush is employed. This brush is dipped continuously into the cleaning fluid, which is then applied to the weld burn areas. The elevated power (amps) of this machine results in very rapid oxide removal, not only on TIG but also on MIG welds. The Cougartron comes in two versions. The standard ‘Cougartron Plus’ cleans TIG and MIG weld oxides, whilst the ‘Cougartron ProPlus’ can also be used for electropolishing small stainless steel areas. With over 40 years’ experience, Anopol are a leader in chemical and electrochemical processing of stainless steel, and other metals, for a wide spectrum of industrial, decorative and functional applications. In addition to offering sub-contract services, plant and chemicals, Anopol can also supply an extensive range of pickling, passivating and general cleaning products for stainless steels. These are suitable for for use by companies who wish to carry out their own processing. Anopol operates from 2 sites, one in Birmingham and the other in Bordon, Hampshire.

Plate flatness is, naturally, critical to the productivity of lapping systems, as the shape of the plate influences the geometry of components being processed and contributes not only to final surface finish, but also to the lapping rates which can be achieved. Increasing control over the groove pattern (macro texture) and lands (micro texture) of the plate surface ensures greater consistency in removal rates and surface finishes. With Engis unique system, when plate reconditioning becomes necessary, the Plate Facing Device uses a diamond tool bit to remove the top layer of the plate and then machines in a groove pattern in a second pass. When not in use, the device retracts out of the work zone. The Plate Facing Device, used in combination with the pneumatic pressure heads of Engis FastLap machine, can consistently achieve accurate plate conditioning, controlled surface geometry and texture as well as fast, predictable stock removal. This results in a lapping process which is easier to manage, with more repeatable results.

Tool stroke position repeatability of 0.1 mm/0.004" is ideal for close-tolerance work in blind bores. Handles both rotary- and push-feed tools. Sunnen’s new HTR all-electric job-shop tube hone combines servo precision and cycle-automation features with constant spindle power and 0.1 mm (0.004") stroke repeatability to efficiently hone blind bores or correct tight spots in a bore without operator intervention. Designed and equipped to hone the wide variety of parts encountered in a job shop, the machine handles bore I.D.'s up to 900 mm (35.41"). Its modular design can be configured for stroke lengths from 2.5 m to 14 m (8' to 46.2'). Critical for job-shop versatility and productivity, the HTR's 12 kW (16-hp) spindle motor, combined with a four-step gearbox, produces a constant power band through the entire speed range of 10-470 rpm for fast metal removal. The standard servo rotary tool feed can also function as a push-feed system with an optional drive shaft that converts rotary to linear motion, allowing the machine to handle the full range of Sunnen heavy-duty and two-stage tools. Tool overload monitoring ensures optimal stock removal rates, while protecting the tool and workpiece. Precision stroke position and repeatability are ensured with a servo rack-and-pinion stroking system. It drives the spindle carriage at speeds of 0.1 to 48 m/min (4" to 157' per minute) on hardened and ground ways with a 10.2 kW (13.6 hp) servomotor, giving the machine plenty of power to handle superabrasives for fast material removal. The HTR's design eliminates all hydraulics to vastly reduce maintenance, noise, leakage and heat, as well as system hysteresis due to hydraulic oil heating up. The machine's 305-mm (12") Windows® touchscreen PC control manages all machine functions, including stroke speed/position, tool feed, spindle speed, stone wear compensation and cutting pressure. Standard control features include size lock, automatic bore geometry correction, recommended setups, tool overload protection, spark out, spindle jog and short stroke. The control can store up to 900 different part programs and be configured for 13 languages. The HTR's optional easy-to-setup fixturing is available in two ranges for parts 40 to 600 mm (1.6" to 31.8"), and parts 50 to 810 mm (2" to 31.8").

Cooling lubricants have become an essential part of metalworking. They reduce friction losses between the tool and the workpiece, dissipate heat and guarantee long tool lifetimes. However, what is important after machining is not just that the parts are produced error-free, but also that they are clean. MQL operations produce residues on the parts and in the holes/threads that are very difficult to clean, and they can also create tramp-oil layers in the subsequent water miscible process steps, which is also not helpful. For this purpose, Henkel provides customers with an integrated product solution. In this way, the water-miscible cooling lubricants from the Bonderite L-MR range convince customers through their ideal combination of high lubrication and rinsing performance in one product. They are not only free of bactericides, but also permit, due to their high hard water stability, a long bath-life. Thanks to the excellent washing and lubrication capabilities, particularly good rinsing behaviour and therefore very low drag-out of the product concentrate, Bonderite L-MR cooling lubricants are highly economical. Due to the properties of the finely dispersed Bonderite L-MR emulsion, tools, machines and processed parts consistently remain clean during the production process, have a long tool-lifetime and produce outstanding good surface finishing. Downstream cleaning steps are thus substantially more efficient. Another innovation is that the pure concentrate of the innovative 2 in 1 cooling lubricant Bonderite L-MR 21972 can be used as a minimum quantity lubricant. In this way, parts processed with the product as a minimum quantity lubricant (MQL) can be cleaned more easily. Maximum cleanliness in the production process The high-quality, aqueous, generally neutral or slightly alkaline, cleaning fluids in the Bonderite C-NE and C-AK product series have been specially adapted to the cooling lubricants. They ensure efficient process, parts and maintenance cleaning, even at low temperatures. Biostable formulas ensure that the biological, easily degradable wetting agents do not lose their effective properties, even when used at low temperatures. This means that components of any material can be optimally prepared for further production processes such as bonding, coating or painting. A selection of special cleaning agents are available for sensitive light metal alloys, which, in addition to the removal of the processing agent, also activate the surface for the subsequent processes. Under the designation Bonderite C-AD, additives which are essential for the optimisation of the cleaning process complete the range of available products. An overview of the entire process In order that the metal pre-treatment process takes place quickly, error-free and effectively, Henkel has developed a complete, programmable control system called Lineguard. It provides the 56 Grinding & Surface Finishing n SEPTEMBER 2015 perfect support for maintenance of the process parameters. Aligned to the Bonderite L-MR cooling lubricants and the various cleaning agent types in the Bonderite C-NE and C-AK product series, this modular system gives excellent results in quality, efficiency and process reliability. Due to this integrated production solution, Henkel represents a strong system partner for all metalworking companies which place great value on safe, clean and effective overall processes. Henkel operates worldwide with leading brands and technologies in three business units: Laundry & Home Care, Beauty Care and Adhesive Technologies. Founded in 1876, Henkel holds globally leading market positions, both in the consumer and in the industrial businesses, with well-known brands such as Persil, Schwarzkopf and Loctite. Henkel employs almost 50,000 people and reported sales of 16.4 billion euros and adjusted operating profit of 2.6 billion euros in fiscal 2014. Henkel's preferred shares are listed in the German stock index DAX. Looking back on nearly 140 years of success, Henkel’s vision is to become a global leader in brands and technologies.

The units can handle the heaviest loads encountered in industry to clean up contaminants generated during milling, drilling, tapping, turning, grinding and other machining processes that utilise emulsion mist coolants. The EM Profi collector uses long-life coarse and fine filter demisters followed by a final-stage HEPA filter with combined efficiencies of 99.9 percent on particles of 0.3 micron and larger. This is much higher than capture efficiencies achieved with fiberglass V-bag filters, which lose efficiency as media becomes saturated. A patented automatic sprayer counteracts emulsion clumping, ensuring that the separators can operate "24/7" almost maintenance-free. During routine annual maintenance, the unit is easily serviced from the ground by a single technician, eliminating extra manpower and lift equipment. Service life between change-outs is up to six years for demister filters and two years for HEPA filters. Large maintenance doors and quick-clamping elements facilitate fast, tool-less filter replacement. Due to these features, Handte EM Profi collectors achieve substantial savings through reduced downtime, longer change-out cycles and increased productivity and reliability. Sturdy modular construction is another benefit. Basic modules can handle air volumes from 1,700-8,000 cfm, with a wide range of accessories and configurations for optimum flexibility. Modules can be combined to accommodate larger airflow requirements. Small space-saving models are also offered for low airflow applications of 500-1,400 cfm. Last year, U.S based Camfil APC acquired Handte, the leading German provider of mist collectors, wet scrubbers and other environmental products, with over 120 years of experience and worldwide automaker references. Handte's offerings complement the equipment offered by Camfil APC, a leading global manufacturer of dust and fume collection systems and part of Camfil, the world's largest air filtration company.

The sensors are designed for high precision profile and dimensional measurements on a variety of materials where red laser diode sensors do not perform well. The scanCONTROL BL series of blue laser profile sensors operate using blue (violet) laser technology rather than red. The special characteristics of the blue wavelength laser light make the scanners suitable for measuring against shiny, highly polished metals, as well as red-hot glowing metals and silicon-based materials. All the controls and electronics are integrated in an extremely lightweight, compact sensor design, enabling the scanners to be installed in locations where there may be little space available for mounting. The scanCONTROL BL series offers a range of interfaces and flexible installation options. Chris Jones, managing director of Micro-Epsilon UK, comments: “Unlike a red laser, the blue laser operates at a shorter wavelength of 405 nm, which is far from the red part of the visible spectrum. This means it is unaffected by the emitted infrared radiation from hot or glowing targets, due to implementing a simple optical filter, which ensures very stable signals. Additionally, when measuring on shiny surfaces or highly polished metals, where red lasers tend to suffer from higher noise, the high precision optics and shorter wavelength of the scanCONTROL blue laser profile sensor performs extremely well, providing much lower noise levels, typically by a factor of two or more compared to red laser sensors.” The scanCONTROL BL series is available with measuring ranges up to 265 mm in the z-axis (distance/profile height) and up to 143.5 mm in the x-axis (laser line length/profile width). Output of measurement data is via Ethernet (UDP, Modbus) or serial interface (RS422, Modbus). In addition, analogue signals or digital switching signals can be output directly to a PLC. Profile frequencies of up to 2,000 Hz and a measuring rate of up to 2,560,000 points/sec enable the sensors to be used in high speed applications. Easy integration and connection to PLCs All scanCONTROL series sensors (blue and red) are equipped with a Gigabit Ethernet interface for transferring profile data, as well as a multi-purpose connector for RS422, Digital In (HTL/TTL), power supply and synchronisation. The sensors support Power-over-Ethernet (PoE), which reduces the need for an additional power cable. Micro-Epsilon has also released a new LabVIEW driver for scanCONTROL series sensors. The LabVIEW instrument driver 2.4, available as a 32-bit or 64-bit version, is a convenient interface between sensor and 58 Grinding & Surface Finishing n SEPTEMBER 2015 LabVIEW test and measurement environments. As well as updating existing modules, further ones have been added that enable faster, easier set up and configuration of scanCONTROL sensors. In addition, the driver includes several example programs that illustrate the ease-of-use of these modules. Chris Jones states: “A major selling point for the scanCONTROL series is how easy the sensors are to set up and configure for applications. The software programme supplied as standard with the scanner enables the user to configure the device to a unique IP address. A Modbus protocol, which is supported via Ethernet and the RS422 interface, also enables direct connection between the sensor and a PLC and other control systems. We also supply a software development kit and comprehensive command library as standard with the sensor. This provides the user with a communications platform that offers maximum flexibility and performance via direct integration with most common programming languages.” Multi-scanner applications All scanCONTROL series sensors (blue and red) are designed with a high-speed external profile trigger input. In this way, the data rate can be optimised and measurements can be triggered at a specific event in GSF SURFACE MEASUREMENT 58-59_ES CONTENTS 4-5 26/08/2015 09:02 Page 59 Surface Measurement time. This is particularly beneficial when several systems are operating synchronously. Together with its compact design and simple wiring, scanCONTROL is ideally suited to multi-scanner applications. As with all scanCONTROL series sensors (including red laser line scanners) from Micro-Epsilon, the scanCONTROL BL series is available in three classes: COMPACT, HIGHSPEED and SMART. COMPACT scanCONTROL 2900/BL sensors are suitable for both static and dynamic measurement tasks. These compact sensors offer a profile frequency of up to 200Hz and act as profile data providers. HIGHSPEED scanCONTROL 2950/BL sensors offer everything for advanced high-speed and 3D profile applications. A profile frequency of up to 2,000Hz can be acquired using these sensors, which also serve as pure profile data providers. SMART scanCONTROL 2910/BL series offers a ‘plug & play’ solution with integrated controller that is suitable for simple-to-complex measurement tasks. The design of the sensor is identical to the COMPACT and HIGHSPEED classes. The scanner evaluates recorded profiles and outputs the measurement values. Application Finder The new web-based ‘Application Finder’ intelligent software tool allows users to search for the appropriate laser profile sensor from Micro-Epsilon’s comprehensive scanCONTROL series by considering a number of application-related search criteria. On accessing the Application Finder (http://www.micro-epsilon.co.uk/laser-scan ner/applications/index.html) users are presented with three main search criteria: by Material, by Measurement or by Industry. Within each of these sections, users can further refine their searches by clicking on a variety of filters. Micro-Epsilon is a major global manufacturer of sensors, headquartered in Germany. The company’s range of displacement sensors measure everything from to distance, position, vibration, dimensions and thickness, using both contact and non-contact measurement techniques. These techniques include 1D, 2D and even 3D laser-optical sensors and systems, eddy-current, capacitive, LVDT & inductive, potentiometric and draw-wire principles. In addition, Micro Epsilon has developed its own range of non-contact infrared temperature sensors that can measure virtually any target temperature from -40 to +3,300°C. The company also manufactures a comprehensive range of colour recognition sensors.

This new generation of TCT saw blade sharpening technology uses five CNC-controlled axes to machine the tooth sides of carbide-tipped circular saw blades with precision, productivity levels and capabilities beyond anything available from alternate vendors. All commonly used angles are ground in only one cycle, even on saws with group toothing. This makes processing of complex blade geometries a simplistic process for the end user. The new CHF840 has been introduced to deliver a solution for the processing of circular saws from 80 to 840 mm diameter whilst the larger CHF1300 is capable of finishing saws from 80 to 1300 mm diameter. Offering versatility that leaves nothing to be desired, the new CHF machines provide oscillation grinding as standard to remove maximum material rates in a single cycle. The 5-axis kinematics delivers maximum flexibility and optimal movement coordination for short grinding times and to reduce non-production times with an adjustable cam for the ideal tooth positioning. All this makes the new CHF series suitable for side grinding saw blades for the saw mill industry, woodworking, plastic and aluminium processing and also the metal cutting industries. The machines from the CHF series adjust the angles without assistance and even the hook angles and tooth pitch are automatically detected. To further simplify processing for the end user, the CHF makes it possible to machine convex tooth flanks and it has an optional tooth pitch up to 180 mm, which is credit to a second feed pawl for greater flexibility. Additionally, saw changes are possible without adjusting the mounting carriage, so there is no need to set a blade up a second time. The new CHF840 and CHF1300 incorporate a multi-functional hand-wheel that makes operation faster and more simplistic. The axes can be selected and controlled by only one module to avoid the possibility of incorrect operation. This hand-wheel can also be used as a potentiometer in order to carry out speed adjustments in automatic mode. With operator convenience built into every aspect of the new CHF line, there is no need for manual adjustment of radial and tangential clearance angles. This means that operator errors are eliminated and values can be entered as angles or absolute values. With an intuitive Windows based CNC control, the multi-function hand-wheel and the storage of up to 4000 programs that are accessed via a 10-inch LCD colour display, Vollmer has truly covered every angle from the perspective of user friendliness.

Two years ago it moved to new premises in order to expand and offer a blank preparation service to manufacturers of tungsten carbide rotary tools across the UK. Mark Turton began his involvement with tungsten carbide wear parts 20 years ago at Artisan Sintered Products in Manchester, eventually moving to Bohlerit where he was introduced to rod products and new methods of manufacturing. Always looking for an opportunity to set up on his own he moved into consultancy work and was introduced to Hartmetall AG of Switzerland whose products he successfully distributed for ten years, until they were taken over and rod production was no longer an important part of their business. Fortunately Extramet, with whom he had already had some dealings, was happy to appoint him as its UK distributor and together they have gone from strength to strength. Son Matt joined the company seven years ago after finishing his apprenticeship as a dental technician and like his father was looking for a new opportunity. Hartmetall UK provides tungsten carbide wear parts across the whole spectrum of manufacturing with an emphasis on rod products and a particular interest in aerospace and medical tools. Having comprehensive stocks held in the UK ensures customer satisfaction, in-stock items are shipped for next day delivery and stock is replenished on a weekly basis, ensuring that a high level of service is maintained. Mark Turton says: “When Matt joined me it soon became evident that we needed to grow the business and we soon decided that blank preparation was the way forward for 62 Grinding & Surface Finishing n SEPTEMBER 2015 us. We spent over a year studying what other European distributors were doing and more importantly how they were doing it successfully.” In order to provide a high level of service, Hartmetall UK invested in a CNC slitting machine (soon to be two) a dedicated chamfer machine and eventually a Rollomatic NP5 and associated ancillary equipment. “We have become a capacity multiplier. By having us prepare blanks, it allows our customers to reduce preparation time and grinding time allowing them to produce more tools with their existing machines.” One particular customer Hartmetall UK has worked very closely with since establishing this service has seen a 20 percent reduction in material cost and a substantial increase in profit (he’s not saying how much) by using his machines more efficiently. “Of course we would like to do what we GSF FTR TOOL & PROFILE GRINDING 60-69_ES CONTENTS 4-5 21/08/2015 11:04 Page 63 TOOL & PROFILE GRINDING do even better and we have a plans for expansion and to offer new services to a higher level, but self-financing relies on market conditions. By the end of 2015 we will have invested £500,000 in machinery plus £30,000 in infrastructure,” adds Mark Turton. “Having this facility in-house allows for preparation of blanks to customers specification at short notice, producing from one off to a thousand off steps, tapers, ball noses, back tapers is all in a day’s work. “What we will never do is produce cutting tools. We strictly make wear parts,” concludes Mark Turton. The Rollomatic ShapeSmart NP5 is a precision cylindrical grinding machine with five CNC axes and a grinding capacity up to Ø25.0mm. The peel grinding method is well proven by Rollomatic providing extreme/length diameter ratio as well as complex profiles. Furthermore the rigid design of this machine with its powerful 8.5 kW spindles motor and a wheel diameter of 250 mm, allows for the grinding of parts requiring high stock removal. The ShapeSmart NP5 has a fast and reliable 3-axis integrated tool loader with capacity up to 1,000 pieces. The ShapeSmart NP5 can also be fitted with end probing for length referencing of blanks before grinding. This option is particularly suited to grind the neck and taper on milling tools and form cutters that have already been flute ground.

Prima’s comprehensive tool range includes TCT dowel drills, router cutters, PCD profile router cutters, profile spindle tooling and saws. In addition to providing a wide range of standard TCT and HSS also Prima Tooling also design and manufacture one-off, cost-effective specials that are tipped with Polycrystalline Diamond (PCD). To help accommodate the growing demand for the company’s products, in 1987 Prima relocated from the company’s original Romford, Essex-based factory to a new, larger facility in Brentwood. Reflecting the continued growth of the business, since the relocation Prima’s Brentwood facility has doubled in size. Paul Wiggins, Prima Tooling director explains: “Our impressive success in the manufacture and sales of tooling has been brought about by ensuring that each of our products is designed to deliver maximum efficiency and long life usage to our customers. We don't just manufacture and sell tools, we offer expert advice on what is the right tool for a particular application. Also, if potential customers have a problem, we'll help them to solve it.” To keep pace with its growing output, Prima Tools’ management recently researched the available tool and cutter grinders that would enable the manufacture of high volumes of premium quality tooling. Paul Wiggins continues: “Even though we were aware of the excellent reputation of ANCA tool and cutter grinders, we did consider a couple of other brands. Although, after a successful demonstration, we were certain that ANCA’s advanced MX7 machine would give us with the kind of flexibility we need for the efficient production of high quality tools and would also help in the manufacture of our PCD tooling. “The very adaptable nature of the MX7 64 Grinding & Surface Finishing n SEPTEMBER 2015 was a key factor in our decision to buy the grinder and its level of flexibility provides us with a real competitive advantage. Features such as a ten-second wheel and tool changeover time means that, as well as undertaking high-yield, relatively long production runs, we are now also able to make quick changeovers to accommodate our smaller batch sizes. To make the MX7 even more productive and to enable us to keep up with increasing demand, we purchased our new grinder fitted with an ANCA FastLoad-MX, tool loading system. “The excellent service and training we have received from ANCA UK, in addition to the ease of use of ANCA’s system, has allowed our operators to quickly become proficient in the MX7’s operation and to produce the required quality and quantity of tools. We consider the ANCA MX7 and FastLoad-MX combination to be ‘future-proof’. Together they have the ability not only to handle our current production requirements, we are also confident that the ANCA grinder and loader combination will be able to cope with all of the demands placed on them in the foreseeable future.” The ANCA MX7 is a versatile CNC grinding machine that was designed to meet the challenging demands of high volume production grinding. Described by ANCA as a next-generation machine tool, the state-of-the-art grinder incorporates a range of advanced features that render it, not only ideal for today’s grinding tasks, but GSF FTR TOOL & PROFILE GRINDING 60-69_ES CONTENTS 4-5 19/08/2015 14:55 Page 65 TOOL & PROFILE GRINDING also capable of adapting to the need of an ever evolving marketplace. The robust, rigid design of the MX7, along with its range of unique features has resulted in the creation of a flexible, highly productivity machine package that is capable of handling high-precision work and varied batch size production with minimum setup time. Driven by global tool manufacturers’ demands for precision grinding at lower unit costs, the highly efficient MX7 focuses on the area of greatest demand and is optimised to grind tools of up to 25 mm diameter. Designed specifically to meet the demanding needs of tool production facilities that seek maximum output while remaining adaptable to customers’ needs, the flexible MX7 delivers outstanding spindle performance across the entire spindle working range. A permanent magnet spindle provides high torque at lower rpm, this is particularly suited for carbide grinding. With six HSK wheel packs, the MX7’s efficient wheel pack changer increases machine productivity and flexibility by enabling a 10-second wheel change time.

The Basildon (Essex) based company is using its four Helitronics, including the more recently installed Helitronic Vision tool grinder and Helicheck Pro tool inspection machine, to maintain its leading reputation for tool regrinds, primarily of own-brand tools, to a wide customer base throughout the UK, Ireland and Europe. Importantly too, the Walter tool regrinding and measuring technology is also helping to ensure OSG’s superlative levels of back-up for its market-leading range of own-brand tooling, in particular its high-precision carbide tools for the aerospace industry. Based on OSG’s worldwide technical relationship with Walter, the Helitronic Vision tool grinder with robot loader and Helicheck Pro tool measuring machine are the latest additions (installed in 2012) to the UK company’s portfolio and these form an integrated cell. The multi-axis Helitronic Vision features a mineral cast machine bed and gantry design, and provides a massive 30 kW of spindle power. Coupled with sophisticated drive technology plus synchronous linear motors for its linear axes and synchronous torque motors for the rotational axes, the machine generates unrivalled grinding times and superior surface finishes. The machine’s Fanuc LR Mate 200iC/5L robot loader can handle workpieces 250 mm OSG UK's Walter Helitronic Vision also has a robot loader and four-pallet system long and weighing 1.5 kgs and it operates in conjunction with a four-pallet system that provides a storage capability of up to 1,500 workpieces. Capacity can be optionally 66 Grinding & Surface Finishing n SEPTEMBER 2015 increased to 3,500 workpieces with eight pallets. This is coupled with the 4-axis Helicheck Pro measuring machine which has a repeatability of +/- one micron and a measuring resolution of 0.25 micron. The machine can accommodate tools measuring 200 mm diameter by 300 mm long. The Vision-Pro cell is used mainly for processing small batches of specials and is linked with the Helicheck for immediate feedback of measurement data and, where appropriate, real-time corrective action. Supplied by Walter Ewag UK, part of the United Grinding group, these machines sit alongside a Helitronic Power Regrinder and two Helitronic Powers, all fitted with cylindrical pallet loaders able to accommodate 280 tools, depending on diameter. “The loaders are a big asset,” says production manager, Mick Brown. “We can GSF FTR TOOL & PROFILE GRINDING 60-69_ES CONTENTS 4-5 19/08/2015 14:57 Page 67 TOOL & PROFILE GRINDING put several different batches of parts on the loader. All we do is instruct the machine where each batch is located and the rest is automatic. It means we can run the machine overnight and therefore make savings.” Fully utilising the robot/loaders, the Walter machines constantly run unmanned and through the night producing batches of up to 30-off. Around 5,000 tools are reground every month. “Lots of people can easily go wrong with regrinding, where repeatability is everything,” continues Mick Brown. “It’s therefore key that the right machining technology is operated by suitably skilled operators to ensure that the reground tool matches the customers’ demands exactly. Our strength as OSG is that we have access to all our original geometries, which means when we regrind tools we can get back to 100 percent tool life. At least that is always our aim. “This is where OSG UK continually scores,” he adds. “Because we successfully combine high-technology machining on the Helitronics with our in-house tooling expertise, we are confident that in many cases our regrinds are even better than many other alternative originals.” OSG UK’s continual progression ( it currently employees 45 people, including two apprentices) also depends heavily on its ability to immediately supply a comprehensive range of cost-effective tooling from an extensive in-house stock. Indeed, orders for standard tools taken up to 5 pm are despatched on the same day. The whole operation is underpinned by a sophisticated ERP system. The company has also recently acquired PN Tools of Atherstone, Warwickshire, an established manufacturer and regrinder of carbide and HSS tools. The renamed OSG PN Tools is already investing in its future with Walter Ewag UK via a Walter Helitronic Mini Automation multi-axis tool grinder being ordered at the behest of Tony Cooper, OSG UK’s sales director and a director of OSG PN Tools. “To meet increasing demand, the new Helitronic will reinforce the quality of PN Tools’ production to customers in industry sectors that include aerospace and automotive,” he says.

KG in Weilheim, Upper Bavaria is restructuring its management team. A new five-member executive board under the leadership of CEO Martin Sackmann intends to get the traditional company ready for the future. The Weilheim company has had two directors since the end of 2013, who helped the company back on its feet after some hard times: Martin Sackmann, who was responsible for sales and all business aspects, and Thomas Seyßler who was in charge of all technology matters. Thomas Seyßler's contract has ended and he has left the company. "We need to develop some new momentum for the realignment which we started two years ago", explains Martin Sackmann. "This is why we are now putting a team of experts in place." Together with the new management team, Martin Sackmann is planning to make the strengthened company even more modern, active and responsive in the future. The new management team will include both familiar and new faces. Dr. Georg Mörsch will join ISOG on August 1st. The 50-year-old with a PhD in physics will lead the technology department in the role of CTO. His responsibilities will include development, manufacturing and quality management. The longstanding HR manager Johanna Jarosch (49) will contribute her expertise as CHRO. Supply chain expert Bernd Weisgerber has been with ISOG since January. As COO of the new team, the 42-year-old with a Master of Business and Engineering is driving improvements to business operations. He is looking after supply chain management and logistics, as well as managing the manufacturing orders and assembly. All financial topics will continue to be managed by Richard Blau (52), who joined ISOG one 68 Grinding & Surface Finishing n SEPTEMBER 2015 year ago as interim manager in order to restructure the finance department. He is on the management team in the role of CFO. CEO Martin Sackmann (50) continues to be in charge of sales, project management, service and application technology. Together with the technology specialist Mörsch, he is planning to further the targeted expansion of the service and application technology departments. ISOG is planning to grow in these two areas in particular:. "The customer is always at the centre of everything we do", that is and will continue to be Martin Sackmann's motto. "We work for our customers, and we work with our customers. Because we can only benefit from ensuring that the dialogue with GSF FTR TOOL & PROFILE GRINDING 60-69_ES CONTENTS 4-5 19/08/2015 14:58 Page 69 TOOL & PROFILE GRINDING our partners is as direct and friendly as possible. Nobody knows the ISOG machines as well as someone who works with them every day. We want to acquire and incorporate their knowledge and their experiences." The changes to the management structure will be reflected throughout ISOG and the new drive is expected to be felt even in everyday operations. Every member of the management team is assuming responsibility for their own area of the company and will be working closely with their respective teams. Weekly coordination meetings will ensure that ideas are implemented quickly and that any problems are tackled and solved in a targeted manner. "The industry has already noticed that we are stepping it up", states Martin Sackmann. "Soon it will become clear that we are stepping it up even more, something I'm looking forward to."

When removing non-polar and partly as well polar impurities, solvents such as chlorinated hydrocarbons and modified alcohols are able to achieve high cleanliness requirements in a reliable, efficient and sustainable manner. When it comes to choosing and using the right solvent, SAFECHEM offers not only a complete product portfolio for solvent cleaning, but also comprehensive services, from consulting, laboratory services, service elements and training to an innovative chemical leasing model. “Equal solves equal” According to this principle, solvents such as chlorinated hydrocarbons and modified alcohols are the preferred choice for non-polar impurities such as machining oils, greases, waxes and resins. They are characterised by good material compatibility, so that parts made of virtually any metal can thus be cleaned. At the same time, cleaning is carried out without corrosion, oxidation, chemical burning, matting or other alteration of the surface. But which solvent is best suited for a particular application? To answer this important question, SAFECHEM Europe GmbH, a subsidiary of The Dow Chemical Company, considers the entire production environment on the one hand because substances carried into the solvent bath play a crucial role, while on the other hand, the CHEMAWARE laboratory services including solvent analyses and oil compatibility tests support the decision process and the optimal combination of the service elements. Cleaning using chlorinated hydrocarbons As a result, DOWPER MC is being used at Gebrüder Kunze GmbH, an important German automotive supplier. This solvent is a virgin, specially stabilised perchloroethylene which has been developed for difficult cleaning tasks and for degreasing metal parts that have a high degree of soiling. The company produces millions of net shape parts made of steel, stainless steel and aluminium; during their cleaning and degreasing process, a lot of oil is carried into the solvent bath, including The cleaning of complex sandwich and monolithic composite structures prior to bonding is critical to the quality at Aircelle Ltd., a member of the SAFRAN Group. Therefore, DOWPER MC perchloroethylene is used. chlorinated oils. Due to the distillation process, acids can be formed over time, which may result in corrosion of the cleaning equipment and a reduced solvent lifetime. To prevent this, SAFECHEM conducted oil compatibility tests with various stabilisers. The stabilisers used are thus optimally aligned to the oil, so that the solvent can achieve a lifetime of several years. DOWPER MC is also certified for many cleaning applications in the aerospace industry. Aircelle Ltd, a member of the SAFRAN Group, uses this solvent for example to clean complex sandwich and monolithic composite structures prior to bonding when manufacturing engine nacelles. The company decided for DOWPER MC based on extensive cleaning tests. chlorinated hydrocarbons, hydrocarbons as well as aqueous cleaners. This includes, for example, the cleaning of complex heat exchanger components at HS Marston Aerospace Ltd, a UTC Aerospace Systems company. HS Marston produces innovative heat exchangers and fluid management systems, which are used in commercial and military aircraft as well as in motorsport and in the electronics industry. The decision for DOWCLENE 1601 was based on extensive cleaning tests and laboratory analyses. Due to its special formulation the solvent can reliably and reproducibly remove both, non-polar impurities such as oils and greases as well as polar substances such as cooling emulsions and solids like salts and abrasion particles. In addition to the approval for cleaning applications in the aerospace industry by well-known companies, parts cleaned with DOWCLENE 1601 have been certified by the Fraunhofer Institute for Interfacial Engineering and Biotechnology (IGB) to be biocompatible for medical applications in accordance with DIN ISO 10993-5, 2009. Modified alcohols – a versatile alternative With the distillable solvents from the DOWCLENE 16 series SAFECHEM and Dow have developed modified alcohols which have lipophilic and hydrophilic properties. They are used as an alternative to When cleaning parts used in the medical industry, DOWCLENE 1601 achieves biocompatible surfaces in accordance with DIN ISO 10993-5, 2009 DOWCLENE 1601 and the COMPLEASE Chemical Leasing model are the optimal solution for the cleaning of components for manufacturers of innovative heat exchangers, such as HS Marston Aerospace Ltd., a subsidiary of UTC Aerospace Systems DOWCLENE 1611 is a solvent based on modified alcohols with stronger hydrophilic properties.

The DOWCLENE 1621 cleaning medium was developed for flood and vapour degreasing in combined solvent/aqueous cleaning processes. It is used, for example, by Germany’s leading contract hardening shop Schwäbische Härterei Ulm GmbH (SHU) in a hybrid cleaning system.

This is typically done by means of compressed air, which must be generated at a high expense of energy. With the new EcoCVac, Dürr Ecoclean offers an effective dry cleaning system that eliminates the need for compressed air. Apart from delivering enhanced process reliability, the system can provide energy savings of more than 50 percent. As maintenance of the working chamber is minimised it also improves the machine availability. Modern engine and transmission manufacturing lines are designed for maximum productivity and economic efficiency. Accordingly, any cause of interference with a downstream process must be eliminated. This makes it mandatory that engine and transmission parts such as cylinder heads, engine blocks and transmission housings undergo cleaning operations between machining steps. Such intermediate cleaning is often performed by cleaning machines using compressed air. A benefit of this method is that the part is cleaned 'dry'. On the downside, however, generating the compressed air supply is very costly. Moreover, the chips and machining fluid residue that adheres to the product are merely blown off, i.e. allowed to spread around in the work chamber, which will therefore become contaminated quickly. This, in turn, increases the risk of re-contamination of the product, with the possible result of impairing the next processing step. Vacuum suction without compressed air in short cycles With its innovative EcoCVac pre-cleaning and intermediate cleaning system, Dürr Ecoclean has overcome these drawbacks. The equipment relies on the newly developed vacuum suction technology. This ensures that contaminants will be removed not just from the part but also from the work chamber within a mere 1.5 to 3 seconds of process time. The EcoCVac system comprises a pressure vessel in which a vacuum is maintained permanently. This vessel is connected by a pipe to the vacuum chamber in which the part is placed. Once the chamber is closed, a powerful airflow is directed through it, thereby 'entraining' the chips sticking to the part and taking them into the vacuum vessel. A chip clean-out device integrated nearby separates chips and emulsion, allowing both to be discharged separately via a collecting bin and a flume, respectively. More than 50 percent energy savings In the development of the EcoCVac system, resource efficiency was a prime concern. As a result, the system affords much-reduced energy consumption when compared to compressed-air type equipment. Assuming a compressed air Dry cleaning without compressed air can yield energy savings of more than 50 percent in addition to process reliability gains. 72 Grinding & Surface Finishing n SEPTEMBER 2015 consumption of 2.5 Nm³ per part at a price of 1.26 euro cents per Nm³, the cost of one compressed-air blowing cycle amounts to 3.15 euro cents per part. With the new vacuum dry cleaning process, an electric power input of 0.139 kWh per part is needed. At an estimated electricity price of 10.88 euro cents per kWh, power costs of 1.51 euro cents per part will thus be incurred. This is equal to a cost reduction by more than 50 percent. Optimised process reliability and availability In addition to the obvious cost benefits, the EcoCVac shines with its improved process reliability. As the chips are removed not only GSF COMPONENT CLEANING 70-75_ES CONTENTS 4-5 20/08/2015 15:33 Page 73 Component Cleaning from the part but also from the work chamber, the risk of re-contamination is minimised. The chamber must hence be cleaned less often, and at a clearly reduced cost and effort. Moreover, unlike conventional compressed-air systems, there are no nozzles to be aligned relative to the part, for example during commissioning or after a collision. The system's availability rate is thus further improved. As a leading supplier, Dürr Ecoclean supplies automotive manufacturers and suppliers, as well as the broad industrial market, with the latest cleaning technology and systems for surface activation and treatment. With individually tailored technology from Dürr Ecoclean, customers can exploit potential savings for example in unit costs, energy consumption and process time.

By becoming a UK distributor for TEIJO products, IWM is adding to its portfolio general-purpose industrial cleaning machine systems as well as machines that are specifically optimised for use in the automotive and industrial manufacturing sectors. TEIJO machines use water-based technology, obviating the need to use expensive and potentially hazardous solvents. They are ideal for pre-cleaning of components before welding, removal of anti-corrosive treatments before machining, cleaning of engines and engine parts, descaling of cylinder heads and many similar applications. Eco-friendly and robust, TEIJO machines are designed with a closed cleaning fluid system which filters and reuses fluid, creating significant water and energy savings. The fluid normally consists of water and 1 to 5 percent detergent, depending on the application. The machines achieve excellent detergent economy, as the wash liquid can be reused for up to several months, depending on the degree of soiling. Multiple-stage alkaline cleaning, descaling and rinsing, wax removal and rinsing, phosphating and rinsing, are just a few of the many functions offered as standards with the TEIJO multi-stage cleaning machines. To reduce energy consumption, the maximum temperature of the washing fluid is set at 80 degrees C. The short heating time and large fluid tank ensure that even the most soiled components are easily and reliably cleaned every time. “Becoming a TEIJO distributor means that IWM has added another important family of product options for our customers,” explains managing director Carl Hollier. “The TEIJO range of component washing machines complements our own food manufacturing and processing ranges. This collaboration will raise the profile of TEIJO machines here in the UK and it will help IWM to supply efficient and cost-effective solutions to suit an even wider range of customer requirements.” Industrial Washing Machines Ltd Tel: 0121 459 3241 Email: [email protected] www.indwash.co.uk Turbex to present surface treatment lines Automated lines for surface treatment, including anodising and chemical cleaning, are sold in the UK by Turbex as a result of an agreement with Finnish company, Galvatek, whose equipment will be highlighted at this year’s Surface World show (Stand 150). Established for over 30 years, the manufacturer has designed, delivered, installed and continues to service more than 600 turnkey installations in over 35 countries. Galvatek is especially well known in the aerospace industry, as its lines for chemical cleaning, anodising and etching are used in factories manufacturing aircraft parts and engine components, as well as in the maintenance, repair and overhaul (MRO) sector. Supply of anodising plant forms a large part of the business. Such facilities comprise one or several lines and typically use sulphuric acid or a TSA (tartaric sulphuric acid) mix. Chemical cleaning lines are built either for one specific purpose or as part of a larger package where it prepares parts for other surface treatment phases. Turnkey solutions are regularly supplied, complete with waste water purification and recycling systems. Turbex will additionally promote its extensive programme of aqueous cleaning machines, which range from small, bench-top cleaning units to bespoke, multi-tank, automated cleaning and drying lines, often with ultrasonics. Some involve a patented system in which the movements of the holding basket and spray jets are individually adjustable to enhance processing efficiency. Others are aimed primarily at high-precision cleaning applications in the optics, medical, aerospace, automotive, nuclear and electronics sectors, with the possibility of simulated clean room conditions. For processing larger components, the heavy duty Turbex AC range of front-loading, spray washing and rinsing machines are the preferred choice. They are especially popular for degreasing, phosphating, paint removal, de-rusting and descaling. Manufactured from stainless steel, the AC programme comprises singleand multi-stage units with options for one, two or three process tanks. Standard sizes range from one to two metres in diameter, although larger machine sizes are available.

A variety of materials is processed, from case hardening steel through stainless steels for marine use to aluminium for pulleys. Small to large batch production is undertaken, from a one-off repair for a broken-down machine to volume manufacture for the motor industry. As business grew, Steve Cooper and his co-directors found themselves turning and gearcutting in-house but subcontracting out most other work. It included heat treatment, grinding, milling and superfinishing, which polishes gears to reduce vibration, extending the life of a race car gearbox. The approach to finishing the gears changed at the MACH 2014 machine tool exhibition in Birmingham, when Steve Cooper visited the PDJ Vibro stand and discussed alternative options with one of the directors, Paul Hurley. The meeting was prompted by the demise of an old drum-type rumbler that was used to clean heat-treated steel parts at All Gear Services’ factory in Finchampstead, Berkshire. Initially, the gears were sent to PDJ Vibro’s technical centre in Bletchley for descaling, deburring and edge breaking in vibratory bowls operated by its subcontract division. This service is a major part of the firm’s business and more than 35 million parts are processed annually, in most cases within in a 24-hour turnaround, for customers that prefer to outsource the function. However, Steve Cooper’s policy was to bring in-house as many processes as feasible, so a 300-litre capacity vibratory bowl finishing machine from PDJ Vibro’s economy range was installed at Finchampstead towards the end of 2014. Filled with a ceramic medium supplied with a recirculating, filtered mixture of water and metal finishing compound, it has reduced processing time from 10 hours in the old rumbler to just four hours and has drastically improved the finish on component surfaces. Moreover, due to the generous size of the vibratory machine, up to 80 parts can be processed at a time, reducing the previous daily rumbling operations to one or two vibratory processes per week. Around 75 percent of heat treated components at the Finchampstead factory are finished in this way. Only clutch shafts and drive shafts too long for the bowl are cleaned by hand. Of the gears and shafts that are not heat treated, accounting for around 40 per cent of production, some are put through the bowl for a shorter period for deburring and surface improvement. A further recommendation from PDJ Vibro is the imminent addition of a switch on the economy bowl that will reverse the toroidal action of the ceramic medium. It will bring the components to the surface after processing, making them easier to remove. Superfinishing on the increase That is only part of the finishing story at All Gear Services, however. Of the components supplied to motorsport customers, which accounts for around half of the company’s business, 60 percent are currently superfinished. That proportion is increasing as race teams become more aware of the 76 Grinding & Surface Finishing n SEPTEMBER 2015 benefits of reducing friction in transmissions, namely increased speed and lower maintenance costs. Steve Cooper previously sent gears and shafts to a firm specialising in the acid-isotropic superfinishing process. While PDJ Vibro sells new machines that employ the process and offers it in the subcontract department, it tends to be aggressive, eroding metal surfaces and affecting the accuracy of components. So the company normally recommends the porcelain and paste option for superfinishing, which polishes surfaces efficiently but without removing any discernible amount of metal. Steve Cooper sent sample parts to PDJ Vibro for trial processing using the method and was so impressed that all superfinishing is now done that way in the subcontract department at Bletchley. It is also less expensive than the isotropic method. Superfinishing will be transferred to Finchampstead during 2015, for which All Gear Services will buy a second, similar 300-litre bowl filled with the requisite media.

For weight reasons these two metals are increasingly replacing steel as the material of choice for the production of a wide range of components. The soft and, therefore, gentle aluminum media has proven to be the most suitable blast media for treating components made from light metals. The continuously increasing sales of the Walther Trowal THM shot blast systems show a clear trend toward aluminum blast media becoming more popular for blast cleaning of die-cast and forged aluminum and magnesium components. Its obvious advantage over stainless steel media is the drastic reduction of the overall operating costs due to the wear rate of the blast turbines in particular and the machine in general trending to nearly zero. Of course, because of the lower mass of aluminum media, the turbines must throw a much larger media quantity to achieve the same processing results. For this reason, Walther Trowal re-engineered the THM troughed belt shot blast machines to ensure that they can easily cope with the higher media quantities. A highlight of the new THM shot blast machine range is the innovative electric media dosing system, which will be presented to the public at Gifa. These machines were specially adapted for gentle blast cleaning of aluminum and magnesium. But of course, they also produce excellent results on steel, zinc and brass components. Troughed belt continuous shot blast machines The THM continuous troughed belt machines can handle large quantities of bulk produced small parts as well as large, delicate single workpieces with complex shapes. Because of the much simpler and gentler workpiece handling they frequently replace conventional batch tumblast machines. THM continuous feed machines are especially advantageous for treating very delicate components: Contrary to batch tumblast machines, where the parts are continuously tumbling over each other with a high risk of nicking, in the Walther Trowal THM machines the workpieces are spread out throughout the length of the trough, ensuring a gentle, nick-free processing. The workpieces are not tumbling over each other but gently roll over the polyurethane coating of the transport rods. This is extremely important for highly complex thin-walled parts, which must increasingly undergo an intensive blast cleaning process. The results are perfectly cleaned parts without any nicking or other damage. Compared to spinner hanger machines the THM continuous shot blast systems have also significant technical advantages: Because the workpieces are gently tumbling through the troughed belt, they are 78 Grinding & Surface Finishing n SEPTEMBER 2015 exposed to the blast stream from all sides and, especially, always at the same distance from the turbines, ensuring all around, even shot blasting results. Aluminum: The gentle shot blasting media Generally the blast cleaning of die-cast or forged aluminum components, for example, steering knuckles, requires a relatively soft blast media. But there is also an increasing trend towards the use of aluminum blast media for processing magnesium components, especially in the automobile industry. Many structural automotive components, for example, dashboard mountings, are made from magnesium. This material has not only a low weight, but at the same time, is also very tough. Due to the fact that in the Walther Trowal THM shot blast systems the distance between the workpieces and the turbines is very short, the aluminum blast media, despite its low density, has still a very high kinetic energy when hitting the workpieces. This is ideal for processing components made from aluminum and magnesium. The THM continuous shot blast machines can be equipped with a different number of turbines. For example, for forged aluminum components the THM 700/4/E with four (4) turbines with 15 kW each offers an optimum performance. A design that is totally adapted to aluminum To ensure the proper handling of the aluminum shot blasting media, the Walther Trowal engineering team has completely GSF METAL FINISHING 76-81_ES CONTENTS 4-5 21/08/2015 11:05 Page 79 Metal Finishing redesigned many key equipment components like the media dosing system and the blast turbines. Just one of the many details: Since a rough surface on the throwing blades would quickly wear down the aluminum blast media, the surface of the blades is smoothed in a vibratory finishing machine before they are installed in the turbine. The result is drastically reduced media consumption, lower dust emissions and a significantly higher uptime of the turbines. Continuous feed or batch processing For integrating the THM systems into automated manufacturing systems Walther Trowal offers a range of part feeding and handling systems like, for example, vibratory conveyors or angled belt conveyors. Many customers link the Walther Trowal blast cleaning systems directly with their forging line or die-casting machines. But the THM systems can also be operated in batch mode. In such cases the workpieces arrive at the blast machine in special part bins and are transferred into the machine with lift & tip loaders. Large workpieces are placed manually on a special belt conveyor. Safety comes first Since aluminum and magnesium dust is flammable and can be highly explosive, it is of utmost importance that the dust concentrations generated by shot blasting of light metal components with aluminum remain low. In numerous design details the Walther Trowal engineers made sure that only small dust quantities are produced during the shot blast operation and dust deposits in the machine are prevented. One example are vibratory conveyors for transporting the blast media, which totally preclude the formation of dust pockets. In addition, the dust-loaded air is cleaned in special explosion protected dust collectors, and the air speed in the machine and the ductwork is constantly monitored. Walther Trowal GmbH & Co.

He also paid tribute to the professionalism and technical expertise of all the staff at Riley Surface World, who worked very hard to complete the project on budget and on time. Riley Surface World is a trading name of Riley Industries Ltd. The company was founded in 1966 as Barry Riley and Sons. The original premises were located in Central Birmingham, UK, close to the world-famous Hockley jewellery quarter. Barry Riley started by trading in recycled nickel during the great nickel shortage of the late 1960s, supplying the large number of nickel plating companies that existed at that time. This steady income allowed the company to diversify into a much wider range of second hand surface finishing plant and machinery. It eventually moved to larger premises at Perry Barr to the North of Birmingham city centre, where the business flourished throughout the 1980s and 1990s.

The facility, developed in response to the specific requirements of one of Gestamp Tallent’s major automotive customers, has been installed in conjunction with an upgrade of the company’s existing effluent plant to accommodate increased throughput and, significantly, sees the first use in the UK of the new Koch Rejuvenator filtration system. With initial testing having proven the installation performance, the line is now fully operational, accommodating a range of suspension, chassis and axle components manufactured by Volvo. Mike Fisher, environmental manager at George Koch, explains how the new facility is meeting developing needs in the sector: “Ever-increasing quality standards within the automotive industry have highlighted the need to eradicate silicon-based deposits that can appear on the welds of subassemblies, potentially causing defects to the finished, electro-coated product,” “Removal with an alkaline degreaser followed by acid-etching at 50°C using a product based on 10 percent sulphuric acid has proved to be particularly effective in addressing this issue,” The fully-automated plant processes manually-loaded parts suspended from an overhead conveyor through nine stages including spray and dip cleaners, rinse stages, the acid-etch and the application of an inhibitor ahead of product storage. Because the new installation also means an increase in the amount of wastewater that needs to be handled at the site, with a particular requirement for treatment prior to sewer discharge, George Koch’s expertise in this area too has been utilised by Gestamp Tallent. “The original need had been addressed by a precipitation plant for more than 20 years but the new acid-etch plant pointed towards an upgrading of the facility to enhance the customer’s environmental performance while handling the larger volumes involved,” says Mike Fisher. He highlights the fact that George Koch was able to remove the existing plant and install the new facility within just a nine-day summer shut down period to ensure that loss of production was avoided.
