Pietro Colombo President & CEO 3 EvoBus Bohemia, in the Czech Republic has optimised the production layout Much less space for double the parts INSPIRED FOR TUBE Transport and doubled its output of bus parts thanks to three laser tube machines The increasing requirements for lower production times, higher quality and precision, together with the increasingly stringent standards are the main reasons for companies being forced to invest in avant-garde machines and technologies. This is the case of EvoBus Bohemia s.r.o., a branch of EvoBus GmbH headquartered in Germany, who are specialised in the production of body shell segments for Mercedes and Setra buses. We produce parts for about 50 different bus models at the Holýšov facility - says Mr. Václav Šeterle, Production Manager of EvoBus Bohemia These range from the single deck urban buses to the suburban and regional double-deckers. The production consists mainly of the shells, that is the front and rear parts and the front and rear panels of the buses that are made of standard steel and are phosphatized after machining”. Up until 2005, all parts were manufactured following a complex production process using “traditional” machines, such as cutting, boring and milling machines, a number of times. With the introduction of the first ADIGE LT 712D laser cutting system, production at the Holýšov facility changed drastically to the point that there are now three laser systems. The advantages were so great that only three months from the first, a second laser system was purchased and then in June 2007 a third system. “Three systems in just over three years is such a short period when compared to the two years that it took to convince us of the enormous potentials and benefits of laser technology to cut tubes and profiles” says Mr. Šeterle. “When BLM illustrated the features of the ADIGE lasertube sys- L L L 4 The laser turn Transport INSPIRED FOR TUBE tem back in 2003, we were extremely impressed, but all the same, it took us a year to carry out a thorough analysis before deciding that the LT 712D would have been the most suitable machine to fulfil our needs. Then in the autumn of 2004 we purchased the first system that was started-up the following year”. A fundamental element in the choice made by EvoBus was the after-sales assistance provided by ADIGE, thanks to staff of R.D.I. spol. s.r.o., sole agent for the BLM Group in the Czech Republic. “Having chosen to invest in a machine that at the time expressed a level of technological innovation that was new to us - explains Šeterle - the training and assistance received before and after installation was absolutely fundamental. Besides maintenance and choosing the correct technological parameters of the laser, the ADIGE training courses helped us to design and produce “special” parts, exploiting the potentials of the new technological procedure 100%”. From 10 to only 3 days With the use of the LT 712D system, EvoBus was able to double the number of parts produced and, by no means of less importance, to reduce the 6 Václav Šeterle amount of space required for the machines on the shop floor. Operating with a Kanban type production rate, use of the laser has, in fact, reduced the need to handle and manipulate parts, at the same time giving better quality and cutting down on production times that have dropped to 3 days from order compared to the 10 that were previously required. Tubes with lengths of 4 to 6 m are fed into the laser systems to produce the finished product at the end of the process.”. These laser systems have therefore replaced traditional machining so that the entire process is now Transport INSPIRED FOR TUBE EvoBus Bohemia is now also able to meet the most stringent European standards in matters of safety, thanks to the three Lasertube systems that have substituted the cutting, boring and pressing machines previously used. The production process at the Holýšov u Plzn plant has further been optimised by the installation of a roller table, which conveys entire lots of material without any production downtimes. The laser is also fitted with a suction system that collects waste in suitable containers and thereby avoids handling of hazardous products. EVOBUS BOHEMIA S.R.O. K. Evobusu 610 34562 Holysov tel +420 379 822 139 fax +420 379 822 155 www.evobus.com EvoBus has also installed a BLM CNC tube bending machine of the DynamicD8 line that allows multiradius bending (variable or fixed) with a single locking system. This machine has brought about a radical improvement in the repeatability of bent parts, which is important for the operations that follow, such as robotized welding of the structures. Nombre 9 - octobre 2008 carried out on a single machine, and this has considerably reduced the number of rejects. The laser systems process tubular material from 20 × 20 up to 100 × 120 mm, with a maximum wall thickness of 6 mm. With the most recent laser systems, even open profiles can be machined (U, L). 7 Epedal S.A. in Portugal has made its location a competitive advantage to emerge in the automobile components field The advantage of being in Portugal Since 1987 Epedal S.A., which was founded in 1981 to supply the motorcycle industry, restructured itself to produce components for the automobile industry. Today, it has reached a remarkable size with 180 employees and 11,000 sq.m facility. 8 “The initial choice immediately favoured the automation of the production processes to exploit the guaranteed quality level as well as the integration of the various machining processes” says José Alexio Santiago, General Manager of Epedal S.A. “We work tubes, wire and sheet and assemble them to complete components for the automotive industry, which in itself is competitive, but we are “We handle over 10 million components per year with an export rate of 85% in Spain, France, the Czech and Slovak Republics. We are confident that we have followed the right path seeing that to date the growth in sales and turnover has brought its rewards by doubling in only four years. Our quality is often certified directly by our cus- tomers. In fact, we are VDA Volkswagen - A, as well as ISO 14001:2004-BVQI and ISO TS 16949:2002-BVQI certified”. Make investments, get efficient production processes The remarkable results achieved by Epedal in such a short time can be attributed to the considerable efforts made over the last three years with investments pivoting around 25% of the annual turnover made by the Portuguese company. Nombre 9 - octobre 2008 just as much. We work three shifts in order to meet our customer’s requirements, even if it means during the holiday periods, and we have never lost an order” emphasises Mr. Santiago. L L L 9 OEM INSPIRED FOR TUBE And while Mr. Santiago shows us his shop floor, it is evident how these investments have been converted into production processes. A well-equipped moulding department with 15 presses, in-house tool shop producing moulds and samples, tube working and assembly shop with 21 welding robots that unequivocally “communicate” the considerable capacity to efficiently produce even the most complex component made with various tube, wire and flat sheet elements, mainly with absolute quality. The tube processing department consists of an ADIGE TS72 cutting machine with in-line end brushing and washing, two BLM E-TURN40 bending machines for right and left bending, a Dynam0 MR200 and a Dynam0 LR150. To work the tube 10 José Alexio Santiago OEM INSPIRED FOR TUBE From one batch to another with minimum downtimes “All the machines installed in the tube processing department - says again Mr. Santiago - are configured as automated cells with fully automatic loading and unloading operations so that there is no need to have a dedicated operator. The advantages of having a modern and stateof-the art machine shop not only lie in the level of automation. In our case, the real flexibility that allows us to switch from one batch to another with the minimum amount of downtime is a definite advantage. Moreover, the guaranteed repeatability for batches that are getting smaller and smaller and distributed in the long-term prevents us from having waste and rejects. On the other hand, we must appeal to our customer and not make them feel that we are well over the western borders of Europe. To the contrary, in fact the competitive advantage that we can still boast about in terms of cost is combined with the high professional level of our personnel and technology”, concludes Mr. Santiago.

Indústria de Componentes Metálicos, SA Bicarenho - Sangalhos 3781-908 Sangalhos Tel. +351 234 730 180 [email protected] www.epedal.pt In the near future, Epedal is planning to expand to Gliwice, Poland with the implementation of a production facility of 2,000 sq.m in which the Portuguese know-how will help to grow further and to serve several customers. Nombre 9 - octobre 2008 ends, two BLM units have been installed consisting of an AST100NC with automatic loader and an AST25 to process small diameter tubes. 11 Olaf Janitza About twenty machines integrated in automatic stations make Wielpütz, one of the major users of BLM systems in Germany Automotive Organised for the top end The factors of success Olaf Janitza lists three factors of success that he believes are fundamental to the development of the company: “ we aim at the best training level of our employees, from the production division to the technicians. Tool design and manufacture is carried out in-house, therefore it is a key specialisation. We use the BLM tube bending and end-forming machines that are integrated in our automatic production units”. This “love” for the BLM systems started back in 1997 when the first Dynam0 tube bending and AST38 end-forming machines were purchased. The machines are tailored to meet our exact needs, including integrated loading and unloading. At the end of the day, the cost/performance value proved that BLM is one of a kind”. Therefore, it is of no surprise to find that there are 12 Dynam0 machines, including the latest rightleft in-process model and 7 end-forming machines, which include both the hydraulic AST38 and the all-electric TUBE-FORM Ele models. This Nombre 9 - octobre 2008 The company has a century old history. It was founded in Solingen to cut metal and evolved considerably over the years in terms of product, location and technology. “We have now reached a head count of over 100 - says Mr. Janitza - and the increased turnover in the last few years is an effective indicator of the ability to respond to new customer demands”. The headquarters in Hilden not only have the administrations, design and mould construction divisions, but also tube and wire and plastic processing, assembly and quality control. The second facility located in Solingen deals with the heat treatment such as welding and brazing. INSPIRED FOR TUBE Gebr. Wielpütz, located in Hilden, Germany, is one of the main users of BLM systems and Mr. Olaf Janitza, Technical Director tells us why. “Speed, improvement, reliability, precision and economy. Every year the pressure and expectations from sub-suppliers of automotive parts increases more and more in a global competition that just cannot be avoided”. Wielpütz, supplier of 100% of automobile components, produces tubes for measuring the oil level in engines (10 million/year), water cooling and hydraulic pipes for leading vehicle manufacturers such as VW & Audi, Ford, GM and many well-known sub-suppliers. L L L 13 Automotive INSPIRED FOR TUBE 14 makes Wielputz one of the leading users of BLM systems in Germany. “Over the years, we have been able to try out and appreciate the evolution of the various models” continues Mr. Janitza. “The old DNC models were sturdy and reliable and when the PC-controlled models came in, the operators took some time to get used to them, but nowadays with the level reached by the VGP-3D, we just cannot do without them”. Moreover, the output has more than doubled; the VGP-3D is a software that also makes it possible to process offers: “with the bending simulation, we know the precise cycle times before producing or implementing the tools”. Eight automatic production stations handle batches of anything from 1,000 to 60,000 pieces. The ninth station is in the process of implementation. “The BLM machines have been designed so that they can be perfectly integrated in this production logic” states Janitza. “A robot takes care of handling the pieces and according to the various combinations, loads them onto and unloads them from the tube bending and end-forming machines or conveys the pieces towards the welding machine. There are many solutions that we have designed ourselves to ensure a high degree of flexibility of the stations”. Nowadays, the production department handles 800 different components with characteristics and processing needs that can be extremely different on materials ranging from aluminium stainless steel and steel. “This allows us to supply both small and large batches and to win orders for niche vehicles that are produced in small quantities”. The various BLM Dynam0 models manage to handle these variants well, thanks to its capacity of up to 20 mm diameter and in-process left and right hand bending direction with the LR150 version. The BLM integrated loading and unloading devices have now become a usual part of production”. GEBR. WIELPÜTZ GMBH & CO. KG Max-Vollmer-Str. 10 40724 Hilden Tel 02103/203-6 Fax 02103/203-88-837 [email protected] www.wielpuetz.de Development continues Even the new TUBE-FORM Ele end-forming system, the first all-electric machine of its kind, which was installed in April, has met with the production requirements. “It is even more accurate and repeatable than the previous hydraulic generation that we were used to, and moreover, it is even faster” explains Janitza. “Thanks to the know-how and reliability of the machines, we can focus on further developing tools and integrated processes. In fact, we know the machine parameters well and can exploit the machine to its utmost capacity. This is an important point that contributes to making us competitive in a global market where competition is extremely aggressive”. Nombre 9 - octobre 2008 Suitable for stations 15 BLM all-electric tube bender powers Freeman & Proctor’s The best practice in aerospace is ‘all-electric’ and bent tube under strict quality control, with a raft of industry and customer quality approvals highlighting the ISO 9001:2000-accredited company’s commitment to continuous improvement. INSPIRED FOR TUBE Aerospace drive to ‘world best practice’ Specialising in the manufacture of high quality, fabricated, tubular assemblies primarily for aerospace applications but also for automotive applications, Freeman & Proctor Ltd’s 30,000 sq. ft. factory in Nuneaton is home to an impressive array of machine tools and related equipment. CNC lathes and machining centres produce components that are welded or brazed to precision cut Established in 1949, Freeman & Proctor manufactures various components for its aerospace and automotive customers, including high-pressure fuel pipes (including double skin dual fuel and hydraulic pipes), electrical conduits and hydraulic pipes, small bore fabricated pipe assemblies such as fuel manifolds and air breather pipes, fabricated suspension struts used on a high-performance sports car and air injection pipes used on a V8 twin-turbo, high-performance petrol engine. And the installation of a BLM ETURN ET52 all-electric CNC tube bending machine is the latest step in what Roy Collett, Managing Director, describes as the drive to ‘world best practice’. Aerospace INSPIRED FOR TUBE Roy Collett A member of the Society of British Aerospace Companies (SBAC), Freeman & Proctor has the capability for complex assembly of flight control systems as well as the specialist design and manufacture of aerospace pipes and fabrications. It provides systems integration and project management expertise, together with technical support from the design stage, and complies fully with AS9100, the widely adopted and standardised quality management system for the aerospace industry. This quality management system incorporates the entirety of the current version of the ISO 9000 standard, while also specifying 27 additional requirements relating to quality and safety. All major aerospace manufacturers worldwide require compliance and/or registration to AS9100 as a condition of placing business with their suppliers. Freeman & Proctor is also committed to SCIRA, a UK industry-wide programme that aims to improve the performance of the aerospace supply chain by cutting out waste and maximising value transfer. The supply chain relationship within and between companies involved in aerospace work has long been recognised as a key factor influencing the UK’s ability to compete and increase its share of the world aerospace market. So the SCIRA code of practice is playing a key role within Freeman & Proctor in promoting partnerships, team working and greater efficiency throughout the manufacturing process. “We don’t have intellectual property in the form of design rights but we have developed a niche manufacturing capability with the emphasis on scheduled business,” says Roy Collett. “Our mission is to give customers confidence that Freeman & Proctor will be around to support long-term Nombre 9 - octobre 2008 Ensuring that components are right-first-time L L L 17 contracts and that we have equipment and systems in place capable of ensuring that components are right-first-time, 100 per cent inspected and delivered on time.” Complex 3D configuration In its primary market of aerospace components Freeman & Proctor has a limited demand for this mirror image capability – components are, typically, complex configurations in difficult materials and called off in small batch quantities. On conventional hydraulically-powered tube bending machines set-ups can take up to two hours to complete and depend heavily on individual operator skill and know-how. In contrast, the BLM E-TURN uses ‘stacked’ pre-set tooling on each of its two heads, thereby accommodating Freeman & Proctor’s six sizes of tube and specific bending requirements without incurring significant set-up time penalties. A further advantage is that a repeat order merely requires the operator to call up the relevant program with 18 the confidence of knowing that there will be no material wastage during set-up and every finished part will be correct to specification. “Because of overseas low labour cost competition we have tended to go for the more challenging parts,” says Roy Collett. “This involves larger sizes of tube and greater complexity, which is why we have installed the BLM ETURN. Scheduled business allows us to plan long-term investment but I also want this new machine to attract new business, by inviting people to see it in action and alerting prospective customers to our new capability.” Complex components requiring radii of less than Centrovell Estate, Caldwell Aerospace Freeman & Proctor Ltd Road, Nuneaton, England.

The electric axes automatically adjust position, which enhances accuracy and repeatability, and components are not only produced ‘right first time’, they are repeatable batch to batch without undue reliance on operator expertise. And, since all axis movements are set automatically, a job change-over can typically be completed within two to three minutes. This multi-tool stack tube bender brings with it fewer bend tool changes and less downtime. The VGP 3D software allows checking on-screen, providing a reliable guide to component cycle times and identifying any possible collision risk. And because the PC-based control selects the correct parameters, the guesswork is taken out of tube bending and the most complex of tubular components can be completed in one cycle. This new machine is also extremely environmentally friendly, since power is only required during axis movements and means power consumption can be as little as 10 per cent of previous generation machines. “We asked other people about their experiences with BLM before we placed our order and we are also really pleased with the way BLM has supported this installation“, says Roy Collett. “Ten sets of tooling came as part of the package, which also included the control, VGP software and operator training. If everything goes to plan, we will be looking at a second BLM machine next year.” Nombre 9 - octobre 2008 1 x diameter can be produced on the E-TURN using the ‘bend boost’ device, which can have its power modulated during the bending process to avoid unsightly stress marks on high-value components. INSPIRED FOR TUBE Warwickshire, CV11 4NG. 19 Tubilaser Srl offers a modern service for pre-machined and semi-finished products The service culture for large tubes A lasertube to soundout and educate the market INSPIRED FOR TUBE Structural steel work either as a complete supply or sub-contracted work in the field of large tubes Flavio Colusso, Elisa Zanatta, Guido Bonaldo. Tubilaser Srl, located in Ponzano Veneto in the Province of Treviso, is a relatively young company that has taken the cutting edge with its specialisation. Regardless of its establishment in the not too distant 2000, the company can boast skill and professionalism in the field of laser cutting of small, but mostly large tubes and solid profiles thanks to an experience that derives from a more distant past. 20 The business originates from the previous working experience of the partners, who, as told by Mr. Guido Bonaldo, Managing Director of Tubilaser “by marketing and distributing mechanical and structural tubes nationwide, we saw new opportunities for expansion. Some of our important customers started asking us for more than just the supply of tube. Therefore, the foundations were already there to build up on and provide and guarantee a modern service of pre-machined and semi-finished products in the tube and solid profile sector, either as a complete supply or just machining. This led us to purchase our first ADIGE Lasertube LT652 system, which helped us to soundout and educate the market by supplying a product with added value compared to the usual standard”. “To soundout, because the laser tube permitted us to deal with a wider range of customers and to understand that besides a few applications in the field of agricultural and earth handling machines, the main opening for our type of service was the furnishing sector, which was used to a higher quality level, even from an aesthetic point of view” explains Mr. Guido Bonaldo. “We immediately understood that it was necessary to expand further, introducing our processes to different and better performing fields in terms of component dimensions to be Structural steel work INSPIRED FOR TUBE The needs and requirements of Tubilaser found an unmatchable partner when they came across the laser tube skills of ADIGE, who stimulated them to develop the laser cutting system for round tubes from 10 up to 508 mm in diameter, square from 10x10 mm up to 400x400 mm, rectangular from 20x10 mm up to 500x300 mm with wall thickness up to 20 mm and lenghts up to 14 m, known as the Jumbo system, which was then installed in the Ponzano facility. On-time supplies and guaranteed results “The aim was to use the Lasertube as we were already doing, but for much lager dimensions – says Guido Bonaldo – to satisfy the sectors that were not used to such high quality standards and precision, therefore, “thinking of a tube” as a fundamental element of any structure was an absolutely new way of thinking. It was for this reason that I previously mentioned education. For example, in the construction field, even though the validity and benefits could be sensed, engineers and designers were not used to designing structures based on the use of large tubes and profiles. The lack of suitable means and reliable technology made those who should have worked tubes reluctant to such a point that any inclination towards innovative design was dampened. Our choice to invest resources and energy in such an important technology and although it was a “pilot project”, it turned out to be a winner and this is all merit of the reliability of the Jumbo solution that was fine-tuned by ADIGE”. Our strength was that of being able to count on a sound customer portfolio, thanks to the previous experience that permitted us to play not only the technological card, but also the “ace” of tried and proven tube processing know-how that had been gained with the first laser. Anyone who placed their trust in us never turned back, because the quality aspect had improved and they could count on a good service with precise leadtimes and guaranteed results. Material has now become very expensive. In the past year alone it has doubled; this means Nombre 9 - octobre 2008 processed, such as that of heavy structural steel work, machine and frame constructions and structural buildings”. 21 Structural steel work INSPIRED FOR TUBE that a piece of tube to be worked on the Jumbo machine can cost thousands of Euros more and if these pieces are worked with inadequate and poor performing means, then one risks on throwing away an awful lot of money. Our final customer pays for semi-finished products ready for being assembled and therefore eliminates any risk of errors. This is an excellent condition”. A bridge in Liverpool, Rome’s Ciampino airport, a football stadium in Ghana built for the African football championships and a hangar at Bologna airport are only a few of Tubilaser’s credentials. The third “stand-by” shift The advent of the Jumbo allowed Tubilaser to start looking beyond the boundaries of the home market and more towards the Northern countries like Germany that has an avant-garde building culture as far as the use of tubular structures is concerned, but also in unexpected countries such as Croatia and Slovenia. “In the “Slav” countries we found a far greater opening and tendency towards the type of service we are offering; in fact, they are far more open compared to our countries in the North East, in which the ability to get by is still a limitation” points out Guido Bonaldo. “Whereas in 22 Slovenia and Croatia there is a cultural attitude that is more like the German one rather than ours, which has made them approach the large laser tube without any prejudice and to fully embrace it”. Today, the Jumbo system works regularly over the two shifts that are considered indispensable to offset the investment made. “The third shift is a “stand-by” that we use only in particular occasions and with special customers” con- Structural steel work INSPIRED FOR TUBE TUBILASER S.R.L.

Fax 0422.962650 [email protected] tinues Guido Bonaldo. “We prefer to have one shift free and to use it only when there is a machine update or sudden malfunction. If we used the machine over three shifts for a long period and there were an unexpected event, without a “stand-by” we would start to accumulate delays that would affect the service offered to our customers. As Tubilaser’s goal is to provide service and quality, we cannot permit ourselves to get into such a situation. Our clients trust us; they come to us with a date and know that it will be kept; perhaps there may be a delay of just one day, but never one week. This service philosophy has brought us to being a young business, with 12 employees, that I believe still has plenty of margin to grow, but let’s take it one step at a time and at the right time. We do have an investment plan in mind to give an even more complete product and service, because once the customer has experienced the advantages, the tendency is to relieve himself of the responsibilities in exchange for certainty”.
