As a competent partner, AgieCharmilles GF is ready to analyse and implement such projects with its clients. Ralf Löttgen It really does not seem so long ago since, as a 19 year old apprentice, I was aligning the work pieces in the milling machine vice using the centering device and, when manually changing the tool, tightening the drawbar in the spindle, using the Allen key. This year, I am 42 and have obviously changed and in so many ways. In those days the machine tool was, generally speaking, an investment, the cost-effectiveness of which cost-effectiveness, in smaller companies at least, was often not given any further thought. The machines were operated by a skilled worker who carried out all processes and tasks on each machine himself. The machine was his support. In recent years, technology has set the course for the automatic operation of the machine tool, i.e. the provision of all the relevant elements required for the process. More than ever before, the market is dictating conditions, deadlines and prices. It is a question of using technological possibilities and human skills to respond to market demands. A production facility must be productive somewhere between 0 and 8760 hours per year. You will agree with me that anything between 0 and 2500 cannot really be economical and that 8760 is not really realistic. Therefore, let’s assume that 2500 to 7500 hours per year are generally economical and realistic; exceptions prove the rule. To achieve this, the company infrastructure must undoubtedly be adapted to the new situation and orientated towards keeping expensive production facilities in operation. Even complex processes can nowadays run automatically and without direct supervision by an operator. The job profile and the worker’s skills must adjust to the situation. In addition to this are logistical prerequisites such as the provision of tools, NC programs and palletised work pieces in sufficient quantity and quality. Standardisation of the processes and incoming materials is often a prerequisite but it makes things much easier, in any case. production. A typical feature of suitable machines is, therefore, integrated clamping systems (advantage: maximum volume of working area remains intact) or at least fitted ones (disadvantage: part of the working area is lost to the clamping system). 1. Machining Centre with integrated chuck An automatic tool or electrode changer as well as peripheral devices such as those required for cooling lubricant treatment and chip disposal or dielectric processing, callipers etc. are taken for granted and are state-of-the-art and included in the delivery scope of modern machine tools. As such, the introduction of a reference system typically precedes automation. Pallets (Illustration: 3R Macro Magnum system) or other zero point clamping systems are typically used to fix or transport work pieces in a specified position. In conjunction with the corresponding functionality of the machine controller or high-performing workshop management systems, reference systems are the indispensable first step to automated 2. Machining Centre with integrated Pallet Changer Low-cost changing mechanisms which, with limited flexibility and smart efficiency, offer the best possible value for money, provide a start to automatic workpiece handling. They convert a machining centre into an automatic manufacturing cell, which, using suitable software functionality, can be integrated into cell management systems, e.g., Sigma. Such systems have often proved themselves to be interesting alternatives to wideranging automation solutions for the tool and mould-making industry or the production of repetitive components with production times of typically more than 30 minutes per pallet. 3. Machining Centre with programmable Handling Devices Programmable handling devices are used when increased capacity, flexibility and functionality are required or different production mechanisms e.g. machining centres, measuring machines and/or systems for electrical discharge machining are to be concatenated. Typical products are devices with programmable rotatory and linear axes, articulated robots or similar. Once again, the selection is based on the production problem, with the least complex system able to carry out the task usually being the most logical choice, since each additional controlled axis means loss of money, manageable workpiece weight and reliability. Whilst simple handling devices in this category , e.g., 3R Workmaster system, can typically change pallets and carry out sim- ple activities, such as the emptying of cavities as well as transport between a limited number of production facilities, robots are used if the workpieces have to be handled. Articulated robots are generally too expensive for pallet changing and produce no real benefit. If, however, components require direct handling and it is necessary to perform additional tasks requiring complex movements, they are often indispensable. Once again, it is important to mention that, depending on the production task, software such as 3R Workshopmanager system can support organisation and data provision and acquisition, at various levels of development. 4. Machining Centres with Linear Concatenation With the necessity to concatenate an increasing number of production facilities and extensive peripheral equipment, e.g. cooling lubricant or dielectric processing, chip disposal, large capacity for blanks and finished parts, the need for linear concatenation of the components in a manufacturing cell becomes inevitable. Undoubtedly, such an investment must be planned and assessed carefully but it is possibly the best economic solution, or even the only realistic one. As a competent partner, AgieCharmilles GF is ready to analyse and implement such projects with their clients. Whether from our own portfolio (3R Workmaster Linear system) or in collaboration with other partners from the sector, in the case of linear system concatenation we also apply the automation solution which best suits your requirements. 5. Conclusion There is no quick fix for automation or for the optimum exploitation of an investment. The automated production solution Continued on Page 2 High-speed machining 2 Editorial Jens Thing Brand Manager Mikron HSMtoday Nr. 17 The highest quality milling tools by Seco Tools France Seco Tools designs, manufactures and sells tools for metal chip removal. Two HSM 400U and three HSM 600U ProdMod machines by Mikron AgieCharmilles AG are used for production Dear Readers, Today, versatility and flexibility for a company are fundamental prerequisites to capture the market. This issue of HSMtoday once again highlights the versatility of our range of products. For years we have launched high speed machining centres onto the market; the capacity and machining options of these machines remain exceptional even today. Originally, these machines were meant only for mould making. Then in 2004, with the HSM 600U ProdMod, we developed the first machining centre specially intended for production. The systematic expansion and integration of palletising systems have made this machine line extremely attractive for other applications too. The automation options have awoken interest from a variety of different areas of machining. But even our other machines, such as the HPM machining centres and machines from the VCP and UCP series, are today used in the most diverse economic environments for the most versatile applications. Our latest offensive is in the direction of medical engineering. With the HSM 400U ProdMed in its standard configuration and with the variants for the manufacture of dental implants, as well as the UCP 600 Vario ProdMed, we will place our technical knowledge, acquired over years, at the service of medicine. Mikron proves its versatility – put us to the test! Seco Tools France is an innovative company which makes an above average investment in research, development and production to face the challenges of the future. The wide tool and clamping tool programme meets a variety of requirements during milling, turning and drilling. Seco Tools is, however, much more than a tool supplier. The company is a reliable partner who, in conjunction with its customers, analyses production technology problems in order to reduce production costs and offer economic solutions. Alexandre Condrau Jürgen Maurer Seco Tools France belongs to the worldwide network of subsidiaries within the Seco Tools Group, which was founded as a steel factory in Sweden in 1929. Seco Tools has manufactured tools for milling, turning and drilling since 1930. The company has more than 4300 employees all over the world in 40 subsidiaries and is, today, one of the world's leading manufacturers of cutting tools. In 1965, Seco Tools France was founded as a 100% subsidiary of the Seco Tools Group. Its tool programme is also intended for turning, milling and drilling applications. The company now has approximately 250 employees, of which 100 of them work in production. The company headquarters and production unit is at Bourges, approx. 220 km south of Paris/France. Seco Tools France is not only responsible for sales in France but also manufactures for the Group. As such, approximately 800 milling cutters are manufactured per week, including both standard and special tools. Approximately 25% of turnover comes from the production of cutting plates. In order to strengthen its market position, Seco Tools France offers a wide range of tools for all chip removal tasks. Moreover, specific solutions are developed which meet all the requirements of costeffective and smooth running production, given that customers are naturally interested in the highest productivity and cost-effectiveness. Cooperation and customeroriented thinking are, therefore, of paramount importance for Seco Tools. Today’s requirement for justin-time deliveries, as well as tough competition, forces businesses to have short reaction times. Universal tools are, therefore, required which can satisfy a wide range of requirements with high productivity. The production of cutting plates is a source of new challenges for Seco Tools. Replaceable turning plates are absolutely essential as, today, there is frequent use of prefabricated “near net shape” workpieces with a small final measurement, at almost actual size. They must guarantee good chip breaking and control especially at shallow cutting depths, high cutting speeds and large feeds. Given that the chip removal volume is low, small, cost-effective turning cutting plates are used. Seco Tools Continued from Page 1 suited to your application must correspond to the basic conditions, financial possibilities and the future direction of your company. There are regions in which a yearly output of more than 5 000 hours for a machining centre in manual operation is typical. In the western industrialised countries such times are generally not achievable without automatic workpiece handling. AgieCharmilles GF has adapted to this and, from the preconfigured product up to the individual automation solution including advice and project management, offers a complete portfolio based on the requirements of your production problem about to be solved by automation. Discuss your ideas with our sales companies. They will work with you and AgieCharmilles GF, New Application and Systems and Automation to develop an automation solution, tailor-made to suit your requirements. www.mikron-ac.com constantly discovers better cutting materials and optimum geometries for excellent chip removal results by applying state-of-theart turning plate technology, and carrying out continuous research and development. Thanks to the tremendously rapid development in tools and machines, machining today is three times quicker than 25 years ago. The increase in cutting speed, feed and cutting depth generates increased heat on the contact surface between turning plate and workpiece (often exceeding 1,000 ºC), thus making higher demands on cutting edge and High-speed machining HSMtoday Nr. 17 3 events. Along these lines, seminars regarding the “machining of complex materials” are offered, innovations are presented by way of special machining demonstrations and reports as to which tools are best suited to which applications. Finished milled part and blank geometry with regard to wear and heat resistance. Seco continues to invest in the development of coated hard metal types, cements and ultra-hard cutting materials. There is a large training centre at the company headquarters in Bourges. Given that tools and machining processes are increasingly complex and continue to improve, Seco Tools France offers regular further education and information Seco Tools chooses Mikron machines For the manufacture of tools for metal chip removal, Seco Tools France chooses machines by Mikron Agie Charmilles AG from Nidau in Switzerland. The first HSM 400U was purchased in 2003. Due to the excellent machining quality, another machine of this type was purchased the following year. In August 2005, an HSM 600U ProdMod was added. The executives at Seco Tools France were so convinced by this machine that, in the space of one year, another HSM 600U ProdMod was purchased. The expectations of Mikron’s machines have been fully met at Seco Tools. Production times have been reduced by over 20%. The HSM machines have also proven themselves by virtue Mikron’s HSM machines satisfy the greatest demands regarding speed, accuracy and surface finish quality Seco Tools chooses Mikron machines for the production of milling tools of their accuracy and stability. The stunning surface finish and the increased tool service life testify to the optimum ratio of machine robustness and machining output of the Mikron machines. At Seco Tools France, only pretreated steel with 48 HRC is processed. Production is handled by two teams, 7 days a week, with approximately 50% run as manless operation. The Mikron machines are automated with Erowa robots. The milling heads to be machined at Seco Tools France are fixed to devices manufactured by Seco and can be directly set on the Erowa ITS 148 or PC 210. The production machines The HSM ProdMod machines are specially designed for production. The results are high speed machining centres with the highest dynamics for economical machining of exacting precision parts for medium to large series. They are equipped with highly dynamic direct drives for the B and C axis. The models in the HSM series have a monoblock machine base made of polymer concrete, constructed according to the frame overhead version. This basis has been tried and quality. With their requirementoriented design, high quality components, digital drive technology, as well as one of the most modern control systems, they are designed for maximum value, cost-effectiveness and functionality. At the Seco training centre in Bourges, regular seminars are held for customers, commercial partners and Seco employees tested for several years both on HSM 400 machines and machines in the HSM 600/800 series. They leave nothing to be desired with regard to rigidity, damping behaviour, access and compactness. The high-performing motor spindles by Step-Tec in various versions according to speed and torque ranges have contributed to the success of this machine series. Today, more and more users are opting for an automated HSM machine by Mikron. As such, the set-up times can be achieved during the primary machining time and the plant running times can be extended during the manless evening and night shifts. These two advantages must not be underestimated, especially when manufacturing parts in medium and large batches. Mikron’s HSM machines satisfy the greatest demands regarding speed, accuracy and surface finish www.secotools.com mikron-ac.com Universal machining 4 HSMtoday Nr. 17 The UCP 600 Vario is at home anywhere Whether a small or large enterprise, whether machining steel, aluminium or plastic, the UCP 600 Vario is given an enthusiastic welcome everywhere! Mikron is known for its spirit of innovation, and in recent years, has defined many trends in the area of standard, high speed and high performance machining centres. The market does not often react as positively as it has to the UCP 600 Vario, which was publicly displayed for the first time at the EMO 2003. Martina Uebersax Different markets have different requirements for machining centres. With its UCP 600 Vario, Mikron has in its portfolio a product which delights customers worldwide in equal measure. The huge market acceptance of the UCP 600 Vario clearly shows, above all, that customers are not demanding reliable and powerful individual components, rather an efficient, cost-effective system, which is well-rounded and complete and which can also react to inputs from outside the system. The UCP 600 Vario is suited to the most wide-ranging variety of applications. This includes cus- tomers who want to produce high quality parts in 5-face machining, such as production companies, who will have to manufacture medium-sized series and various parts in 5-face machining more economically in the future. It is especially customers in market sectors with high salary costs who recognise the business advantage of an UCP 600 Vario with automation. All of the components necessary for successful production are installed in the most compact installation area. The wide and well matched range of milling spindles (12,000, 20,000 and 42,000 rpm) enables the customer to equip the Vario with the required capacity and torque on the tool to match their preferred materials. Ultimately, all Vario customers have one aspect in common: the UCP 600 Vario is as universal in its implementation as the customers’ requirements are demanding and varied. The most wide-ranging materials can be machined including aluminium, normal or stainless steel, titanium and plastic. The machining possibilities range from simple drilling to complex 5-face and 5-axis machining. Maximum flexibility is the unanimous demand made on the machine when producing small and medium series. In this regard, the built-in automation (7 to 10 pallets) is particularly praised by the users. The following customer profiles give an impression of the exceptional versatility of the UCP 600 Vario. www.mikron-ac.com The UCP 600 Vario at Toolmakers in the Netherlands The Toolmakers company from the Netherlands supplies the fine mechanical industry with a wide variety of highly varied quality works which are produced by chip removal. The machine park is equipped to ensure that all chip removal work can be undertaken in the company itself. Furthermore, Toolmakers offers small and medium-sized enterprises a complete service; analysis, development and entire engineering. In total, four machines from Mikron Agie Charmilles AG are used at Toolmakers: three 5-axis Mikron UCP 600 Vario’s, one of which has a pallet changer, as well as a VCP 1000. All machines are equipped with the Heidenhain iTNC 530 control system. Complex parts are manufactured which require a variety of operations. Toolmakers easily manufactures workpieces with tolerances of +/- 0.005 mm. Furthermore, workpieces with a tolerance range of 0.002 mm can also be milled. Extremely short cycle times and 24-hour operation makes Toolmakers stand apart from its competitors. Now, after almost six years experience with 5-axis machining, Toolmakers is extremely satisfied with Mikron Agie Charmilles. An important reason for the investment was the high flexibility of the UCP 600 Vario and, according to the Managing Director, Cuno Hanegraaf: “... with its many machining possibilities this machine has adapted very well to our production spectrum. As such, we were able to broaden our offer and have won over clients for whom we could not have otherwise worked.” www.toolmakers.nl Precision components with the UCP 600 Vario at William Cope Ltd. A Mikron UCP 600 Vario was commissioned in May 2005 at William Cope Ltd, in the United Kingdom. This purchase was preceded by discussions on how to increase productivity and how to improve the production capacity. As a supplier of precision components, William Cope Ltd. has been able to significantly increase its competitiveness following the acquisition of the UCP 600 Vario. Both technical and commercial considerations played a decisive role in the purchase of the Vario. The company is now far more flexible in the production of small series using the UCP 600 Vario. The integrated automation (7-fold pallet changer and the tool changer TCD 30 / HSK 63) enables manless operation. Cycle times have been reduced and costs cut. Fundamentally, the UCP 600 Vario is easy to operate. It guarantees high precision and repeat accuracy with 5-axis machining and is excellent for automatic operation. [email protected] Universal machining HSMtoday Nr. 17 Mikron machining centers are well known für their ergonomic design. The UCP 600 Vario is particularly successful due to incomparable access: The blue area for the operation of the machine and the red area for machine maintenance. Optimum access is guaranteed regardless of the respective machineconfiguration. Basic machine with central 30/36unit tool changer Basic machine with pallet depot (7-10 paletts) and central tool changer Basic machine with pallet depot and tool changer (tower with 120-220 tools) The Precise company from Germany also uses the UCP 600 Vario The UCP 600 Vario in Germany at ATM For over 25 years, the company ATM GmbH in Altenkirchen has been manufacturing laboratory equipment for metallography. Approximately a year ago, ATM purchased a UCP 600 Vario from Mikron Agie Charmilles AG. The deciding factors for this investment,were the combination of excellent price-performance ratio, Mikron's renowned reputation and, of course, excellent machine features such as automation, compactness and ergonomics. The UCP 600 Vario is primarily used for processing aluminium and steel and is equipped with a 20,000 rpm spindle with internal coolant feed and a tool changer with 120 tools. Now, after approximately a year of milling using the UCP 600 Vario at ATM, the company management has confirmed that the machine has fully satisfied expectations. www.atm-m.com machine is primarily used for machining aluminium and steel. So far, the machine has fully met expectations. The automation option optimally designed by Mikron Agie Charmilles is particularly noteworthy. www.precise.de J.E.B. Precision Ltd. and the UCP 600 Vario in the United Kingdom J.E.B. Precision Ltd. have been using a UCP 600 Vario since 2005. The company manufactures precision components and electromechanical assemblies. Their customers come from the optical industry, the medical sector, robot technology, the foodstuffs indus- try and other sectors. With its 5 axes and the built-in 7-fold pallet changer, the UCP 600 Vario offers J.E.B. Precision improved productivity, increased accuracy and greater flexibility in production. It is worth noting that time savings of 60% have been achieved on the machining of certain specific components. www.jebprecision.co.uk Eurocut Ltd. in the United Kingdom. The UCP 600 Vario in medical technology Eurocut Ltd. was founded in 1987 in Sheffield, the United Kingdom. The company now has approximately 100 employees and primarily offers complete solutions for medical technology. The core business is design, development and manufacture of instruments and apparatus for implementation in orthopaedic surgery – especially for hip, knee, shoulder, spine, elbow and toes. The UCP 600 Vario in Spain is used for parts in the aeronautical industry Quality, precision and innovation at Precise are of paramount importance. For more than 60 years it has manufactured milling and grinding spindles in Leichlingen, Germany and in Racine, USA. Appropriate machines are required to manufacture such highlyprecise spindle systems. As such, Precise invested in a Mikron UCP 600 Vario over a year ago. This 5 The Guilo Mecanizados company was founded in 2000. Today it employs 13 qualified employees. Over the years, the machine park has been enlarged to eight NCcontrolled machines. This park also includes two Mikron machines, an HPM 1350U and the UCP 600 Vario. The UCP 600 Vario is used for manufacturing parts for the aeronautical industry. Special aluminium, imbar and titanium are the main materials used. The difference between Guilo Mecanizados and its competitors is that it offers a complete service; from the clamping system to the CAM programming right up to the 3 and 5-axis machining. Guilo Mecanizados has therefore opted for the UCP 600 Vario, “... given that approximately 70 % of the parts to be processed have small dimensions and with the pallet changer we can also process small series using the automatic mode.” Thanks to optimum spindle features, the UCP 600 Vario can be used at low speed and at high torque, particularly relevant when working with titanium, and at high speed when machining aluminium. At Guilo Mecanizados, there is no doubt that the UCP 600 Vario from Mikron has completely satisfied expectations. www.mguilo.com Two Mikron HSM 600 Vario machines were commissioned in the summer of 2006. As the company works in the field of medical technology, the ProdMed machines specially designed for this sector were purchased. The UCP 600 Vario ProdMed makes a significant contribution towards reliable and traceable results in production by combining the monitoring functions of the control system with the “smart machine” modules to monitor spindle vibrations (Extended APS), the automatic calibration of machine geometry (ITC5X), that can be requested in the NC programme, and the option to transmit the specific machine and process status to GPS telephones. The APS “smart module” is a monitoring system which opens up new opportunities for the user to observe, control and correct the milling process. With the help of an acceleration sensor integrated in the spindle, vibrations during the milling process are recorded and displayed to the operator on the console. This enables intervention in the milling process for optimisation purposes. Improved cycle times and process safety, increased productivity and, of course, the splendid automation devised by Mikron, all of which can be achieved with these machines, played a decisive role in the purchase of the UCP 600 Vario. The UCP 600 Vario ProdMed is fitted with a 20,000 rpm spindle and primarily works with stainless steels, aluminium and titanium.. www.eurocut.co.uk Highly productive 5-axes machining 6 Tools for hinge bearing with a Mikron HPM 1000U As development partner for the automotive industry and manufacturing specialist in bulk metal forming and machining (both of steel and aluminium), the Hirschvogel Automotive Group is active in the areas of diesel/fuel injection, gears, drive train, chassis and engine. Hirschvogel has been using Mikron milling centres for years. Jürgen Maurer The Hirschvogel Umformtechnik GmbH was established in 1938 as a smith’s shop by three brothers, Willy, Anton and Hans Hirschvogel. Today, the company employs 2500 people at its four factories in Germany, Columbus/Ohio, USA and most recently China, which was set up in 2005 in the vicinity of Shanghai. The Hirschvogel production spectrum includes hot, semi-hot and cold forming as well as heat treatment and the mechanical machining of forged pieces. The Hirschvogel Eisenach GmbH founded in 1991 originated from the “smith’s shop” department of the former Automobilwerke Eisenach (AWE). At the beginning of 1997, a new factory was set up on a Greenfield site in the industrial area of Marksuhl, 20 kilometres south-west of Eisenach. The company name, Hirschvogel Eisenach GmbH, has now had “Headquarters in Marksuhl” added to it. Together with the Hirschvogel Aluminium GmbH established in 1999, there are at present almost 400 well trained employees at this factory. In a neighbouring area in the industrial estate, Hirschvogel acquired the hall of a company which had gone bankrupt and, after remodelling, tool production was relocated there and extensively expanded. This is where the Mikron HPM 1000U is also installed. The machines from Switzerland are best known at Hirschvogel. There are already 18 Mikron machines at HSMtoday Nr. 17 The Hirschvogel Umformtechnik GmbH in Denklingen, Germany, is one of the world’s largest automotive manufacturers in the area of bulk metal forming and chip removal the main factory in Denklingen and in Marksuhl. The Marksuhl company manufactures precision-formed parts for renowned companies such as BMW, Daimler Chrysler, Volkswagen, Bosch, Siemens, Visteon and Denso. The Marksuhlers have specialised in the forming of chassis parts such as hinge bearings and wheel carriers made of aluminium alloys. In addition, they manufacture precision parts for gears, engine, drive train as well as components for diesel injection. HPM 1000U produces highquality tools for hinge bearings The hot-forming of aluminium corresponds to the basic principle of steel drop forging. This is done at temperatures of approx. 500 °C. Sawed sections of aluminium extruder profiles are, for the most part, heated in cyclic non-stop furnaces. After any pre-forming for material distribution, forming of the parts is done in pre-engraving and post-engraving. To prevent excessive cooling during the forming, the tools must be warmed to approx. 230 °C. Naturally, this requires extremely precise tools. For the manufacture of such complex and high-quality tools, Hirschvogel Eisenach GmbH in Marksuhl bought the abovementioned HPM 1000U in the spring of 2006. Due to its robust structure and the directly driven circular and swivelling axes, the HPM 1000U can be used for heavy roughing jobs as well as for precise smoothing jobs For engineers Horst Hupfeld, Tool Production Manager, and Ronny Pfaff, both from Hirschvogel in Marksuhl, the Mikron HPM 1000U is currently the most flexible machine in its class. Unlike other machines, roughing with the HPM 1000U is clearly faster. “The final contours of the tools are discernible in one go, the HPM 1000U is truly impressive”, says Ronny Pfaff during a visit to the company in Marksuhl, where he was proud to present the new Mikron. While smoothing, we make full use of the maximum spindle speed. “The capacity of the new spindles is really impressive”, continues Ronny Pfaff. “Mikron’s HPM 1000U is exactly the machine that we need for manufacturing our tools. We would like to use it to mainly mill tools for the manufacture of hinge bearings made of aluminium.” Motor spindles of the latest generation were developed for the HPM 1000U. Speed, drive power and torque are perfectly combined for machining according to the HPM milling strategy. The high spindle capacity guarantees short run-up and brake times. Of course the direct drives in the 4th and 5th axis guarantee optimal load of the circular swivel axes, whereby 100% simultaneous operation is implicit. “The five-axis HPM 1000U clearly meets the standards that we demand from modern milling machines. Not only the capacity of these machines, but even the individual components are well coordinated with each other. The unique automation through the HSMtoday Nr. 17 centre of the machine has been well resolved by Mikron. With the remaining components, the HPM 1000U is designed optimally for 3-shift operation. However, Mikron has also thought of the operator, who has unrestricted access to the machine”, explains Horst Hupfeld, who understands machining best. For Ronny Pfaff, the possibility of automating the HPM 1000U was an important requirement and the deciding factor for choosing the machine. The HPM 1000U and other machining centres were also selected because of their long traverse paths giving the advantage of greater flexibility to suit future developments. Horst Hupfeld agrees and emphasises that: “The HPM 1000U is excellent for automatic operation. The machine must largely run manless. This is an important aspect, especially in Germany. The HPM 1000U is a vital manufacturing facility to remain competitive in tool manufacture”. The HPM 1000U is fully designed for automatic operation Due to its robust structure and the directly driven circular and swivelling axes, the HPM 1000U can Highly productive 5-axes machining filter are highly accessible to the operator. It goes without saying that all “smart machine” modules, e.g. ITC, APS or RNS can be used to achieve a cost-effective milling process. What makes the HPM 1000U truly sensational is the solution for automatic loading. Work pieces of up to 800 kg are automatically changed from the pallet magazine to the circular swivelling table. A hydraulic lift/rotation unit (pallet changer) places the preselected pallets on the clamping devices of the circular swivelling table. The optional swivelling setup station on the pallet magazine makes it easier to load the magazine with the work pieces secured on the DIN pallets. The setup station and circular swivelling table have reliable medium connection. Of course, the compact tool changer even in the HPM 1000U that can store up to 215 tools on barely more than 1 m2 is part of the extremely compact design of the machine. This entirely new solution for automating heavy components offers unparalleled ergonomic conditions at the workstation. Access to the working area and pallet magazine is convenient and safe. I) can be variably regulated from the operator console. In addition, minimum lubrication with steam extraction for coolant steam and oil mist is available as an option for the series. It was designed for high efficiency and a long service life. Fully-automatic bellows seal the workspace. The barrier can be automatically unlocked when the swivelling table is manually loaded with a crane and relocked once the loading is complete. 7 instruments, laboratory equipment as well as the CAQ system installed in all production areas, Hirschvogel offers a quality standard that sets the benchmark. This also helps ensure that the quality management systems of all Hirschvogel companies are certified in compliance with the ISO/TS 16949 International Standard. As technology leader of traditional drop-forging, semi-hot and cold forming, aluminium forging as well as machining, Hirschvogel, the family company, has earned a good reputation in the manufacturing industry. To ensure this success in the long term, Hirschvogel must be able to rely on its suppliers and their products. “With the HPM 1000U, we have certainly made a good choice. After all, we can only produce excellent products when we use high quality production facilities”, concludes Horst Hupfeld. Tools and parts of the highest quality are indispensable. High precision forming tools such as the aluminium hinge bearing production are milled on the HPM 1000U. All hinge bearings formed using it must be 100% safety tested and are subject to a strict goods acceptance inspection.

In December 2005, a Mikron HPM 1850U was added to their modern machine park. Stefan Fahrni Jürgen Maurer Whether difficult and mechanically complex injection mould dies for the car industry, large and extremely precise injection mould dies for home appliances or even unusual injection mould dies for special areas, Formenbau Kellermann GmbH always finds the right solution, regardless of the industrial sector. The company focuses on the development and manufacture of complex 3D moulds in single and multi-component technology. The family company has now been running for more than 35 years and, today, is managed by Sabine Kellermann from the second generation. “As before, our objective is to meet our customer’s wishes punctually and by being cost-effective with uniform high quality“, confirms the CEO during a visit to the company. “Over two expansion phases, in 1990 and 1998, here in Postbauer-Heng, we have created optimum framework conditions for our modern production. Our machine park is always state-of-the-art. At the end of 2005, we decided to acquire a HPM 1850U from Mikron. It is now our biggest machine and has traverse paths of 1850 mm in the X-axis and 1400 mm in the Y-axis”, continues Sabine Kellermann. The professional knowledge and readiness of the employees is still the most important basic principle of the company. We lay great emphasis on sharing technical knowledge with trainees. Besides the highest precision and reliability, quality mould making is an important issue at Formenbau Kellermann GmbH. The company has been DIN EN ISO 9001 certified every year since 1998 by TÜV South Germany. The HPM 1850U – the biggest machine offered by Mikron In December 2005 it was time; the HPM 1850U was installed. The initial training was started immediately and progressed rapidly over two months. The combination of highly trained employees and the Heidenhain control system have paid off. With its large table, long traverse paths producing good surface quality during milling tests, a deciding factor in its purchase, and yet compact footprint, the new HPM 1850U is very convincing. HSMtoday Nr. 17 Formenbau Kellermann GmbH is the ideal partner for designing and manufacturing complex tools cally clampable circular and swivelling axes • 5-axis simultaneous machining • Spindles with 15'000 rpm or 24'000 rpm, or 8000 rpm with up to 324 Nm with HSK100 • Work pieces with an interference circuit diameter of up to 2 metres and weighing 4 tonnes Given that in modern car manufacturing the air filter housing must always be built by saving space and thus deeper, the machine must be car interiors that the surface is extremely important“. At Formenbau Kellermann GmbH, programming is carried out at special work places and not at the machine. “This gives us tremendous time advantage and we can work in parallel. With the new machine, we schedule shorter times and still achieve good smoothing results. Our expectations from the HPM 1850U have been fully satisfied”, emphasises Sabine Kellermann at the end of our visit to the company. The versatility of HPM 1850U • High dynamics due to directly driven circular and swivelling axes • Selection between pallet or circular table • Stability during the machining process thanks to the hydrauli- Air filter system for the automotive industry in the position to mill deep moulds with long tools. Even here, the strength and the extraordinary stability of HPM 1850U was evident. “For us, particularly in mould making, it is the ideal machine. With the long tools we can process really deep cavities well and the machine rigidity is excellent”, confirms Sabine Kellermann. “At night we currently run smoothing programmes on the HPM 1850U and the complex processes are carried out during the day. It is precisely when we are processing moulds for Mikron’s HPM 1850 offers long traverse paths: X-axis: 1850 mm Y-axis: 1400 mm and Z-axis: up to 905 mm www.mikron-ac.com www.kellermanngmbh.de High-speed machining HSMtoday Nr. 17 Tooth replacement and parts for the aeronautics industry will be manufactured with the HSM 600U ProdMod and HSM 400U The Eguile Group from Spain consists of the companies Zehatz, DMP and Createch Medical. It is distinguished by a versatile range of products and specialises in the design and manufacture of highprecision parts and tools for the most diverse uses. These products include components for the aeronautics industry, tools for the packaging industry as well as pharmaceutical products. Their range of machines includes a HSM 600U ProdMod and two HSM 400U’s by Mikron in Switzerland. Ferran Santandreu Zehatz has been established for more than 14 years. Together with DMP and Createch Medical, it belongs to the Eguile group, which is owned by Alfonso Urzainki. Today, the company has over 120 employees. Zehatz is distinguished by its flexibility and versatility. The machine park is equipped accordingly, and the most diverse tasks can be accomplished at their factory. High-precision parts and tools are designed and manufactured for different areas such as the aeronautics industry, medicine, electronics or even for the packaging industry. Zehatz always finds the best solution for parts which are difficult to manufacture. For example, in the case of narrow tolerances or when the geometry and manufacturing process are complex due to the material or the required machining, such as in parts for turbines and landing gears for aircrafts. 11 Versatility is the strength of the Eguile group of companies Special steels like Inconel, Nirosta, Monel, aluminium, carbide and titanium are processed at Zehatz. Due to its flexibility and its preference for high precision work, Zehatz clearly stands out from its rivals. Alfonso Urzainki, the CEO, emphasises that only the best processing machines are used. “Only then can we achieve extraordinarily precise surfaces. And besides, we also have one of the best testing laboratories that a company of our size has to show”, he explains, not without pride. This is also in line with his company philosophy: “We must be able to test and We are therefore investing in machines and devices for production and for testing.” certify everything that we manufacture. Only in this way we can offer a 100% guarantee to our customers. I believe that is the biggest difference with regard to our rivals and it enables us to fulfil the requirements of each of our customers. We know what a micrometer is and how much effort it takes to get there.” When asked about the precision and tolerances with which Zehatz works, Alfonso Urzainki explains the situation at his factory: “Each process and each workpiece have their special features, which cannot be generalised. Basically, we can guarantee a precision below 2µm. In future, we want to improve the precision further. The HSM 600U ProdMod For a few months, Zehatz has also been using a Mikron HSM 600U ProdMod. With this machine we manufacture high quality parts because this high speed machining centre is suitable for the rational machining and processing of sophisticated precision parts for medium to large series. The machines from the ProdMod series are equipped with highly dynamic direct drives for the B and C axis. With a pallet changer system and an automatic tool changer, machines from the ProdMod series are especially good for automatic production. The powerful motor spindles, in different versions for different speeds and torque ranges, have also contributed to the success of this machine series. When choosing the HSM 600U ProdMod, some features were of special importance for Zehatz, explains the CEO, Alfonso Urzainki: “The 5-axis machining at high speed and high precision, the flexibility and reliability, the automation option or even the access to a large number of tools and the fact that the pallet changer does not compromise the process when single pieces are being machined or when setting up the machine”, he adds suppressing a smile. The high speed machining centres by Mikron, and the HSM 600U ProdMod in particular, satisfy these standards. www.zehatz.es www.mikron-ac.com High-speed machining 12 HSMtoday Nr. 17 The HSM ProdMod now has 3 axes too Mikron is expanding the ProdMod series with the HSM 600 ProdMod and the HSM 800 ProdMod To ensure that milling machines can successfully be used in production it is not enough to implement the best possible machining process - it must also be long-lasting. Alexandre Condrau New in the ProdMod series Following the market launch in 2004 of the HSM 600U ProdMod with the first high-speed milling centre for the standard 5-axis production of high-precision, top quality work pieces, Mikron is now expanding the ProdMod series with the new 3-axis models, HSM 600 ProdMod and HSM 800 ProdMod. Part Production 24 hours, 365 days The HSM series was originally primarily designed for mouldmaking. The systematic expansion and integration of palletising systems have made this machine line a possibility for other applications, too. Interest has been shown in these high-speed machining centres and their capacity from the most varied branches of industry. In the meantime, the HSM machines are also being used in production. It is here that they are particularly in demand for automation. Every detail is significant Round-the-clock production usually implies fully automated machine operation without super- vision by machine operators. In this environment, each breakdown has far-reaching consequences. That is why Mikron is constantly focused on continuously perfecting its products, paying careful attention to seemingly minor details. Automation of high-performance machining processes The high capacity of 3-axis machining centres simplifies palletisation for maximum loads of 800 kg which are used in linear systems with four stations, as well as tool automation with a capacity of up to 220 tools and a tool change time of only 5 seconds. Error-free chip transport The result of a machining process lasting for several hours is a perfect workpiece and a large volume of chips. The errorfree transport of the chips and media is an absolute priority for the machining process. The ProdMod machine series is equipped, as standard, with a continuous rinsing system for the entire working area and the spindle nose, to ensure that chips do not accumulate and that all chips are diverted from the chip conveyer and filtered. Strong and fast Where there are many chips, there must also be a strong spindle and a robust tool interface. Both are included in the ProdMod series. As an option, the machines can be equipped with an HSK-A63 spindle (22 kW) with 24,000 rpm or else with the HSK-A50 spindle (32 kW) with 36,000 rpm. What has not, however, been modified by Mikron's engineers is the impressive capacity of the linear axes. The ProdMod designs also have the same dynamic features (40m/min/1.7g) which have made the Mikron HSM machining centres extremely highly-renowned. HSM at the service of production From now on, the advantages of the HSM are no longer reserved for those who strive for perfect machining processes. The new ProMod machine range combines the time factor with high productivity demands. Intelligent and independent The “smart machine” modules within the ITC product family provide a guarantee of constant machining geometry throughout the whole day, from the moment the machine is switched on. Thanks to the APS modules, the milling process can be comprehensively optimised, which not only ensures high-quality surface machining but also considerably extends the service life of the spindle and the milling tool. The RNS “smart machine” tool provides absolute reliability when you are planning the number of work pieces to be manufactured. www.mikron-ac.com HSMtoday Nr. 17 High-speed machining Machining moulds using a Mikron HSM 800 13 Glaroform is achieving great results with a Mikron HSM 800 equipped with the 3D measuring system Form Inspect from m&h Thanks to measuring and finishing with a Mikron HSM 800 equipped with the 3D measuring system Form Inspect from m&h in a single set up, die-cast moulds and mould inserts are reliably produced by Glaroform in the shortest possible time, and within fewer micrometres at critical points and with a general tolerance between 0 and 0.01 mm. Karl-Heinz Gies Flower pots, margarine and ice cream tubs and fine food tins, food and non-food packaging, cups, bins, lids whether they are round, oval, square or rectangular with and without fastening and with injection moulded carrying-handle upon request are the end products which are produced all over the world with the fast-running, high-performing moulds by the company Glaroform from Näfels in central Switzerland. They all share the characteristic of very thin walls, which itself indicates how exact the moulds must be. They can sometimes weigh up to 5.5 tonnes when finally assembled. The company designs and produces its own moulds. Each mould is tested and is not delivered until after trial production on one of the company’s two injection moulding machines with clamping forces up to 420 t. An important criteria for both the clients, and indeed Glaroform, is that 95 % of the moulds end up being exported. Forming steels and hardened steels up to a hardness of 52 HRC are machined. A constant increase in hard machining as well as a desire for better surfaces in order to reduce subsequent machining such as grinding, eroding and polishing, were the reasons behind the purchase of a HSM 800. For over a year, time-consuming refinishing work has been replaced by machine milling wherever possible. Even limited sizes which up until now were ground on the coordinate grinding machine are today directly milled, as time is money. The required dimensional accuracies, especially due to thinwalled containers such as margarine tubs, confront production with several intricate problems. The worker is faced with difficult tasks in particular due to the frequent draughts of 8° to 12°. Time-consuming spot-grinding was unavoidable until purchasing the Mikron HSM 800. Measurements on the drafts were difficult and fairly unreliable. For measuring any profiles and geometries you might wish That is why the HSM machine was purchased along with a calliper from m&h, the German machine tool measuring specialists, and its 3D Form Inspect software, for measuring any profiles and geometries you might wish, directly on the machine. The work piece can be measured at any time whilst still in the clamp. For this purpose, the workpiece CAD data is read into the 3D Form Inspect software from m&h. The screen displays a surface model of the workpiece and the operators can determine the points where they would like to check the geometry by simply clicking on the mouse, regardless The HSM 800 working area, equipped with a calliper from the company m&h, Germany Before a tool leaves the factory, tests are carried out on either of its two injection moulding machines of whether this concerns open-die surfaces, grooves, drilled holes or anything else. The software automatically calculates the correct contact paths. Many measuring functions, which are also assigned by clicking on the mouse, make the daily work in the workshop easier. The NC programme is automatically completed in the process. The machine covers all measuring points with the calliper and transfers the measurement values back to the computer where they may immediately be displayed on the screen or saved and distributed as a log or file. A brief automatic calibration is integrated into each measuring programme at m&h, in order to record the machine status. This is how accurate and reliable results come into being. The operator can make corrections immediately and remachine, or the last finishing cut can be set exactly to the desired zero measurement. Glaroform is satisfied that the investment has already paid for itself in the first year. The accuracy, surface quality and the very high availability are greatly appreciated in the HSM 800. As with Mikron, their opinion of m&h is unambiguous: “We would make a similar investment at any time”, confirms the production manager. www.glaroform.ch www.mikron-ac.com High-speed machining 14 BEFA and the rapid HSM 600U ProdMod From project planning to consultation right up to implementation, BEFA supplies turnkey plants for process technology. For milling work, machines by Mikron Agie Charmilles from Switzerland are used. Jürgen Maurer BEFA-Automationstechnik specialises in everything related to plant manufacturing. According to the customer’s wishes or based on their own suggestions, plants are developed, designed on SolidWorks-3D-CAD and then produced on a turnkey basis. Naturally, the company also handles the installation, commissioning, training and, of course, service too. Somehow, they seem to be attracted to difficult and complicated jobs. At least, that is the talk about Berndt Olbricht and Frank Bauer, CEO and proprietor of BEFA-Automationstechnik in Uhldingen-Mühlenhofen at Lake Constance/Germany. Indeed, perhaps that impression is not wrong since both have turned their hobby into a profession. They en- thusiastically design and manufacture even heavy, complicated parts and devices. Such products include their own collapsible high-tech golf cart made of a combination of carbon, special steel and aluminium, materials which at present are only used in high technology areas such as aeronautics and space as well as in Formula 1. They do, of course, also make other things. The legendary 1911 At their premises on Lake Constance, the grip ends and pistol cradles of the legendary 1911 pistol by Colt are milled using 5-axis simultananeous technology. An extremely sophisticated task. They received the order from the arms dealer, Felix Mogdans, who manufactures a 1911 gun specially for sports shooting and arms collectors. The M1911 gun is one of the most well-known guns manufactured by Colt, if not in the world, and was devised by the American gun designer, John Moses Browning (1855-1926). At the beginning of the 20th century, the US army needed a new service gun. When Browning, who was working with Colt at the time, heard about the army’s interest in a .45 gun, he converted his gun designed for .38 calibre for the new .45 ACP (Automatic Colt Pistol) cartridge. The tests lasted almost five years until it was proven that the new gun by Colt was the best and most reliable of the guns tested. As a result, in 1911, this gun was immediately handed over to the army and although this outcome for the test series was expected, they needed time to deliver larger quantities. As the First World War broke out, the guns were also manufactured by other companies under license. Thus began the endless triumphant progress of the 1911 model, on which, even today, many sports guns are based. Felix Mogdans modified the 1911 gun in such a way that the gun he manufactured is nowadays an excellent sports device and collector’s piece. Accuracy and precision Sports shooters need absolute precision and perfect sports devices. To achieve such precision, the machine with which the device is manufactured must obviously meet certain standards. HSMtoday Nr. 17 Innovative special machines? BEFA from Germany faces each challenge Berndt Olbricht with the 1911 model and his chip removal operator Stefan Liehn, who is responsible for the HSM 600U ProdMod For this delicate task, BEFA uses the HSM 600U ProdMod by Mikron Agie Charmilles AG. The ProdMod machines are equipped with the modern Heidenhain iTNC 530 control. The directly driven circular swivel table in linear technology provides for highest dynamics during rotating and swivelling movements. The perfectly integrated pallet changer offers optimum requirements for smooth automatic operation. The HSM 600U ProdMod at BEFA is equipped with a 24,000 spindle. Stefan Liehn, who works as a chip removal operator on the HSM, did not need much time to get used to the high speed of the machine. “It was easy to learn and test, and all that can be achieved with the HSM 600U ProdMod is amazing. Here we use a spherical ball miller with 0.5 mm diameter and obtain an unimaginable surface quality. Finishing is no longer required. The high speed of the machine really impressed me”, he says enthusiastically. Berndt Olbricht also agreed: “I don’t know of any machine that is as good as this one. For me, the design and the extremely short tool changing times were the deciding factors. Besides, it has very low tool wear. I was simply convinced by the good machine concept of the HSM 600U ProdMod by Mikron. The HSM machines specially developed by Mikron for production meet the highest standards with regard to speed, precision and surface quality. With their requirement-oriented design, high quality components, digital drive technology as well as the most modern control systems in the world, they are designed for maximum value, economic efficiency and functionality. www.befa-fn.de www.mikron-ac.com High-speed machining HSMtoday Nr. 17 15 HSM 400U ProdMed HSM 400U ProdMed Dental UCP 600 Vario ProdMed Mikron places milling technology at the service of medicine With its three machining centres HSM 400U ProdMed, HSM 400U ProdMed Dental and the UCP 600 Vario ProdMed, Mikron Agie Charmilles AG concentrates on the requirements of a specific clientele – the offer is directed at manufacturers of medical products. It is precisely in this area where traceability is of particular importance. Mikron offers the conditions required. Alexandre Condrau Mikron Agie Charmilles AG has been supplying machining centres to companies in medical technology for years. These have always been tailor-made solutions which required a lot of time and money on both sides. With the three new models, Mikron is meeting the special requirements of milling machining centres for this clientele. The know-how gained over the years is reflected in the HSM 400U ProdMed, HSM 400U ProdMed Dental and the UCP 600 Vario ProdMed. As a basis for endorsement, Mikron machines are delivered with a range of quality records (positioning, geometry and working accuracy, circularity test, thermal behaviour, test workpiece etc.). HSM 400U ProdMed and HSM 400U ProdMed Dental Particularly worthy of mention in the HSM series are the precision, extraordinary dynamics and high machining speeds achieved. Moreover, it offers excellent chip removal, high flexibility, optimal ergonomics and well integrated automation functions. This machine range embodies the entire knowledge and years of experience gained in high-speed cutting. Mikron demonstrates with the MedTech range that maximum flexibility and top productivity are not incompatible. “Reverse Engineering”, for example, enables the providers of dental technical solutions to close the gap between the physical and digital world. Both HSM machines are based on 5-axis simultaneous machining, in accordance with High Speed Machining Technology. They are both equipped with HSK E40 motor spindles which rotate at 30,000 rpm in addition to feed and rapid feed (with 20, or rather 40 m/min). UCP 600 Vario ProdMed The UCP 600 Vario ProdMed is the optimum machining centre for the production of medical products. In the case of a wide production portfolio, traceability is of utmost importance. Mikron, in conjunction with the m&h company and its 3D Form Inspect software, offers the ideal solution. Unlimited flexibility guarantees a high-performing milling spindle, a high-capacity tool changer, a practical pallet changer as well as an efficient chip removal and coolant process. The 5-axis vertical machining centre is equipped with HSK A63, with a 120tool capacity tool changer and with a 20,000 rpm motor spindle. Due to splendid access and ergonomics as well as an excellent overview of the milling process, no compromise is required when operating the UCP 600 Vario ProdMed. Mikron has an impressive 5-axis solution for automated production with the UCP 600 Vario. The digital CNC control system Heidenhain iTNC530 with which all models are fitted is versatile, flexible and very user-friendly. It can be programmed both at the machine as well as at a separate workplace. “smart module” The scope of delivery includes the following “smart machine” software modules with the three ProdMed machining centres: “APS extended” for monitoring spindle vibrations, “ITC5X” for automated circular swivelling table recalibration (can be requested via NC programme) as well as “RNS”, which specifically transmits machine and process status to GPS telephones. The “smart machine” modules also make a relevant contribution to reliable and traceable results during production. Data related to process vibrations, heat transfers, spindle anomalies and workpiece measuring are saved and are then available for evaluation and documentation purposes. When manufacturing implants, e.g. for skull, jaw, hand, arm, knee, spine and hip surgery, materials which are difficult to machine, such as titanium or steels with a high chromium and nickel content, are used. The profiles are almost always very complex and frequently still very filigreed. The surfaces must, nevertheless, be optically impeccable. This is only possible with Mikron’s state-of-the-art technology within a context that is also cost-effective.

Around 70% of the turnover comes from supplying the car manufacturing industry. In addition, the company also manufactures for the food industry, for transport systems, such as ski-lifts, and for other areas. The “Miscellaneous” area includes the milling of metal crowns with a Mikron UCP 800 Duro. These crowns are required for the subdivision of numbers in the roulette wheel. Jürgen Maurer The Santiano company was founded in 1963 and shared its name with the owner. Until the beginning of 2001, he ran the company personally and then sold it to the three present owners, Silvia Carosso, Dario Banchio and Mauro Giay Gianetto. All three work together in the company. The staff has now grown to over 40 employees. Even before the change in ownership the company had started to modernise the machine park, because Santiano wanted to remain competitive. The company now has the world’s best milling centres at its factories, including an HSM 600U, UCP 800 Duro, UCP 600 Vario and a UCP 710 by Mikron/Switzerland. The Santiano operating works are located in Roletto, approx. 40 km to the West of Turin, the hometown of Fiat. Therefore, the company naturally works for the car industry. Their customers also include famous car forging companies, such as Ferrari. Obviously confidentiality during production of tools and parts is a top priority. No Formula 1 Team would like to show their hand. Santiano therefore does its utmost to ensure that no parts or photographs reach the public. Santiano supplies the railways aswell as the car industry. Heavy cast parts are processed with the UCP 710 for this market. For the SKF multinational, parts for slide bearings, amongst others, are produced on a Mikron UCP 600 Vario. Between 80 and 90% of the components processed by Santiano are manufactured in steel, copper and bronze in small quantities. Regardless of the age of the game with the small ivory ball and Parts for slide bearings, amongst others, are produced on a Mikron UCP 600 Vario for the SKF multinational roulette wheel, fascination for it has not waned, even today. Presumably the allure lies in the fact that there are many betting options or even just the suspense of knowing where the ball will fall. All over the world, the wheel rotates based on Blaise Pascal’s number combination. Roulette – a fascinating game There are many tales and legends about the origin of roulette. The fact however is that today’s roulette is based on an invention made by the French mathematician Blaise Pascal (1623 – 1662). As research for his plausibility theories, he built a somewhat strange machine. His number combination is used even today for the roulette wheel. The game, as such, was not the invention of a single person. According to one legend, Roman soldiers tipped over their chariots and created games using the wheels. The original idea of the game could also have come from Venice, China or India and may have been spread by monks. Roulette found worldwide and unlimited approval when François Blanc, founder of the casino in Bad Homburg/Germany got rid of the double zero which was normal until then. This increased the odds of the player and with this clever move he helped take his casino and roulette to great glory. And they all came: Aristocrats and revolutionaries, millionaires and poets. During the 18th and 19th centuries, roulette spread throughout Europe. In those days, casinos in France, in Baden-Baden and Monte Carlo were particularly popular. What does Santiano have to do with roulette? This question can be easily answered: Santiano manufactured Fotos: Casino Baden-Baden the metal crowns for the roulette wheel. To enable the ball to roll, the metal crown must be milled from brass with extreme precision. No imbalance or other unevenness must appear. Similar to medical products, e.g. implants or bone plates, the milling procedure must also be precisely documented to enable traceability. For this extremely exacting work, Santiano uses the UCP 800 Duro milling centre by Mikron. Mauro Giay Gianetto, one of the Directors, confirms that this machine is excellent and complements the Santiano machine park nicely: “Like the other Mikron machines that we own, the UCP 800 Duro has also fully satisfied our expectations. This machine runs reliably, is flexible to use and we achieve very precise surfaces with it. Our machine operators also handle the UCP 800 Duro well. It is extremely user-friendly and the Heidenhain iTNC 530 control system is also easy to operate.” Today, the roulette wheel is probably the symbol that best represents the fascination, magic and prestige of a first-class casino. Santiano makes a significant contribution to this by milling 100% precise roulette wheels with a Mikron UCP 800 Duro. These wheels guarantee that the ball actually finds its target at random. www.santiano.it www.mikron-ac.com
