INSPIRED FOR TUBE Number 14 May 2011 riginally, the Italian textile firms were using the words "Made in Italy” to distinguish their products from those made in other European countries who did not take too kindly to goods entering their markets from our country.Today, in the era of the global market, those three words have become synonymous with absolute quality and desire for millions of people from all continents. It seems that today the "Made in Italy" brand is the third most renowned after Coca-Cola and Visa. O Opinion 17 March 2011 150th anniversary of the Italian Republic INSPIRED FOR TUBE Made in Italy It is clear that the present meaning of "Made in Italy” placed in different forms on articles of fashion, food and wine or a machine tool goes beyond a mere geographical indication and bears a clear reference to the Italian "lifestyle"; a concept that encompasses many aspects and meanings. It is worthwhile to mention a few that have more immediate feedback in the modern industrial world: the ability to innovate, which results from the undeniable Italian design and high quality of the products, both from a reliability standpoint, the legacy of a tradition of craftsmanship that has evolved successfully into industry, as well as from an aesthetic point of view, the result of the inherent Italian flair for "beauty". To understand why these skills have developed in Italy it is sufficient to take a look at the work of Leonardo da Vinci with machinery and mechanisms of the Atlantic Code, the mechanisms in the Madrid Code or the outstanding studies relating to flying. With these deep-rooted values the Italian mechanical industry has reached absolute levels of achievements. Today, Italy is the third largest producer of machine tools and it is easy to verify the consideration and appreciation of these products the world over. Italian machine tools are synonymous with quality and reliability. As Italians, we can be very proud of being global machine tool manufacturers and exporters of a quality label.

In Greek, Oikos means “house” and no other name could be more perfect and fortunate to Furniture Doing what is needed when needed security door manufacturing. The company was set up in May 1990 by Fabio Buscato and Mario Biancolin who had taken over and revived a company previously operating in the same INSPIRED FOR TUBE indicate a company operating in the field of field. This objective was also reached thanks to the laser tube that made production set to “lot 1” flexible. Lots consisting of 15 identical doors are no longer manufactured, but only a single door is manufactured as a single piece according to a lean manufacturing model. e have been operating in this field since 1984” says Fabio Buscato “As a result, We have almost thirty years of experience and this has enabled us to make Oikos (the name comes from a Greek customer, the meaning of which we learned only afterwards) a worldwide leading company thanks to a quality product in line with the most advanced and current market demands. As soon as we took over the company, we focused on the construction details of our products and tried to be more present on the market. We implemented a double strategy: a technical action to improve the product; a commercial action to extend our presence on the market that at the beginning was exclusively Italian (until 1997-98) to open up first to Europe and later to eastern Europe.” “W Design + security = security door Over the last ten years, or rather since the year 2000 onwards, the security door has undergone a design evolution, from a security product to a design element. “Previously - explains Buscato – the security door, being an apartment entry door, had to “communicate” with the other internal doors; today, its image has changed and it has become a design element that must“communicate”and match with the furnishing. As a result, those who are able to propose aesthetical solutions matching the inte- 5 Furniture INSPIRED FOR TUBE rior furnishing market design trends with the basic function of a security door are winners.Today our company is renowned for this ability on the market - especially on the foreign market and it is considered as the enterprise that is most tuned in on interior furnishing trends. Presently, 30% of the production is exported but the percentage is growing exponentially. On foreign markets we sell the product not so much as security product, but more as a furnishing and design component. We commercialise our products in the United States, Africa, Senegal, Nigeria, South America, Spain, Israel, Greece, China and Germany.The only market that considers the security concept as fundamental, is that of the Eastern countries.” “In Italy – specifies Buscato – we are organised with a network of retailers operating in the field of doors and windows while abroad retailers are interior designers, as previously stated.They are high-level interior designers, all working with the same brands. Quality certification is an important aspect of our production cycle.To sell abroad we are subject to random controls by several certification bodies who check that the production process strictly and accurately corresponds to the company declaration.These strict controls, however, allow us to obtain a quality level certification for our products”. Laser is synonymous with Lot 1 Oikos started off with a craft made production cycle where no special attention was paid to the precision of what was a security door and not a mechanical component. However, this operating method involved some problems during installation that were regularly solved by the blacksmith or by the product installer.“The important evolution took place when we decided to modify the door frame that used to be manufactured at the bending press with an open profile and wide tolerances (0.4 – 0.5 mm)” continues Buscato.“Then, we decided to use a closed profile that featured a definitely better accuracy (0.1 mm); consequently, the machining accuracy and the higher rigidity made installations easier and improved the overall quality of the end product. This change marked the actual passage to an industrial production cycle. It was during this phase that the laser system was adopted by our 6 MAY 2011 NUMBER 14 Furniture INSPIRED FOR TUBE company. Switching to a closed profile with the previous manual machining operations would guarantee a higher rigidity, but would not assure the accuracy that has now enabled us to simplify installations considerably.The choice of an ADIGE LT722D Lasertube by the BLM Group has proved winning, although at the beginning the problems related to the cost and startup of such a large plant frightened us. However, we are reaping the benefits, particularly as regards the easier installation on site.Today, even a person without experience is able to install a security door manufactured by us just by following the instructions”. The LT722D laser has offered a cost saving advantage thanks to time reduction, but the major advantage consists in obtaining the so long awaited “lot 1” concept. Oikos no longer deals with multiple lots, but only with single doors that are tailor-made with customised measures, holes and machining operations. “We no longer need to assemble products in lots – explains Buscato – but enter in the production program a single door that is manufactured as a single piece based on a lean manufacturing model.The laser enables us to obtain a very short production process. The frame is manufactured in 15 minutes; there is no need for bending, drilling, cutting at 45° and making slots on different machines. The end product is manufactured and ready by using one machine only. From January to February we have increased the business turnover by increasing work with less personnel”. “Once upon a time up to 15 identical doors were produced at the same time. Today, however, this market, that is typical of social housing, is no longer found. A dimensional standard exists, but today it is always more convenient to manufacture one frame at a time. There are no storage and transport problems since we make what is needed when needed.” Produced and shipped within 24 hours In conclusion, the main advantages introduced by the LT722D system are the following: machining accuracy and the manufacture of one finished piece in only one passage without requiring additional processing. The accuracy repeatability 7 Software Artube - Composer INSPIRED FOR TUBE Furniture Composer is a software instrument developed by ADIGE within the Artube software to facilitate the production of items that are similar to each other but different in terms of position and/or number of common processing operations. guaranteed by the industrial process allows a considerable saving during other process phases.Assembly and installation problems on site are virtually eliminated and the same frame concept is becoming standard for all products.This is because the profile being used for the frame has been developed to exploit at the best the laser tube system that offers a wide range of possibilities. “Since January we have been trying to launch the product in the production phase in the morning and have it loaded onto trucks within 24 hours”,states Buscato. We have not yet reached that result,since the bottleneck is caused by wood panel working in the joinery, but we are solving the problem thanks to a rapid paint that allows us to process the panel today and install it the next day. Laser and paint are two elements that have allowed to optimise the production cycle.” The Composer parametric module of the CAD/CAM ARTUBE manufactured by ADIGE plays a fundamental role in the automatic production of a door without requiring the design phase. Starting from the information contained in the production order of the operative program,the cutting program of the LT722D system is processed. The answer meets expectations The relationship with BLM has been ongoing for a long time:“When we started the project – Buscato explains – BLM actively collaborated to obtain a good result. It certainly is a rather heavy machine to handle. We want to be sure before giving any guarantee regarding the possibility of reaching a certain result. However, we appreciate anyone who has a serious 8 MAY 2011 NUMBER 14 behaviour and is able to give a pondered response and to maintain it. We were not enticed by the low price and we privileged the result instead. Price is always an essential feature, but first of all the machine to be purchased must meet the demands of the customers, which is more important than price. Another fundamental aspect is the guarantee of a follow-up service, the machines being rather complex and thus requiring an appropriate technical assistance: BLM has deserved full marks from this point of view.” Process files The single processing operations, created by means of CAD Artube, are saved in a database suitably divided by tube section. Each module can be used to create repetitions of a specific process in different tube positions. The use of this instrument is particularly advantageous in some specific sectors. For example, just The security door is environmentfriendly “Thinking about the future – Biancolin concludes – foreign markets will become increasingly important for our product, in which over a period of five years the average price of a door has virtually doubled.We are increasingly oriented towards a high-end market that requires a product with an increasing added value as regards design. In this view, the high flexibility assured by the Lasertube is very important with reference to a single product.Those who are still tied down to high figures today must cope with heavy losses. Moreover, it is necessary to be flexible when producing, but also to meet the new standards and requirements of the building and furniture sectors. For example, nowadays, thermal insulation is strongly felt with the “clima-haus” standard of the province of Bolzano or Trento that is developing in accordance with the American LEED standard.Therefore, our doors as well must be environment-friendly to leave future generations with the same resources that we received. What does it have to do with doors? The simple fact of using coverings with a 15-year guarantee does not require any replacement and assures a certain thermal insulation. These are services offered in addition to security and are added values that guarantee the future success of the product.” think of the manufacturing of frames for doors and windows in which some holes, slots or ordinary machinings are always repeated in the same manner in all frames, but must be positioned in different number and positions in relation to the type of door or window. Graphic interface Avoiding the tube or profile processing design phase, a graphic interface, external to the CAD-CAM system, allows all the stored modules corresponding to a specific tube section to be displayed and to be positioned along the tube axis. At the end, the result can immediately be verified from a graphic point of view and therefore the machine programme can be created directly. Automotive activities that the Brazilian company Alpino Industria Metalurgica, of Italian origin, has been involved in. The tube bending technology that BLM has developed over the years has confirmed the various stages of the company’s growth: from the “Sofia Loren” to the “Beyoncé” with a current output of 1,800 pieces a day INSPIRED FOR TUBE From the furnishing to the automotive industry, passing through the “white” industry; this is the range of for FIAT. In fact, since the very beginning, each new machine has been given the name of a famous woman. From“Sofia”to Beyoncé ... an exceptional cast rom its name, Alpino Industria Metalurgica Ltda, it is clear to see the Italian origins of the Company, which was set up in S. Paulo in 1955 by the fathers of the current owners, Sergio Alonso, Sales Director and Marco Giampietri, Industrial Director and which originally manufactured chairs and tables with tubular elements. “It is not always easy to get along, but this is a fundamental value that has been handed down and we want to continue with it” say the two gentlemen. The relationship has always been based on mutual trust; just think that initially, their parents signed an agreement according to which the signature of only one of the partners would have been sufficient to make even the most fundamental of decisions such as to sell the business. That’s something in the past; nowadays it is no longer so as there are other partners, but the spirit still remains. “No relatives can enter the company unless they have the right qualities and our goal is to continue with the business”. F “Nowadays, our main customers are car manufacturers – explains Alonso – but it hasn’t always been like this because in the beginning we made furnishing components with tubular elements, such as tables and chairs. Our customers not only get punctuality, quality and price, but also added value thanks to the competence and technical innovation that is hard to find elsewhere in Brazil. We always have a solution for the customer, even for the most complex component, thanks to technology. We always try to keep up and invest heavily, even in difficult times like 2008, when the crisis had a really strong impact and came suddenly, like everywhere else in the world; regardless of this, we still purchased an all-electric BLM ELECT 80 tube bending system. I remember being at the Milan trade fair in October and having heard about the crisis, not knowing what people were talking about, but when I got back to Brazil, everything had come to a grinding halt, although the situation was a little particular as there was still demand, but the banks were not financing growth as there was no money to invest”. The milestones of success The technological evolution was fundamental for the company’s growth and marked each milestone, even at the hardest of times like in 1966 when the company got flooded or after the 1998 crisis during which the DYNAM0 tube bending systems were purchased to allow work to start for Whirlpool, Electrolux and General Electric in the gas cooker field. “When we installed the BLM machines, we managed to develop a whole series of products that we were unable to manufacture before both as regards bending and end forming” says Giampietri. “The BLM started many years before, in 1972 when BLM was the only company to have taken the Brazilian market seriously and set up a representative office. Other manufacturers did not have this vision and BLM pioneered. Since 9 then, we have had almost all the machines in the BLM range. The first was a B38, which is still operating at the premises of one of our former employees, who set up his own business; at the time, it was considered an automatic tube bending system as it carried out 12 bends in sequence. When we bought it, my father called it “Sofia” as a homage to Sofia Loren and since then all our machines have been given the name of a famous lady; from “Madonna”,one of the first CNC 3-axis tube bending system (B63CNC) sold in Brazil to “Cicciolina” (purchased in 1987) - a B63 B6X+PMB with which we managed to make a 63 radius bend on a 63 mm tube – something that no-one in Brazil was able to do (and which today only a few can accomplish)”. “In 1972, we were still making furniture - continues Giampietri - but at the beginning of the 80s we started in the automotive field, having developed a bending machine in-house for large diameter tubes. In fact, at the time it was difficult to import machines to Brazil as the import taxes could reach anything up to 100%, 10 MAY 2011 NUMBER 14 but we managed to start working with top brands like Scania and Caterpillar, who are still important references”. In 1989 the purchase of a B120 and a ST130 (5 passes), which are still existing, confirmed the definite turn from furnishing to entirely focus production on the automotive industry. “Having installed a machine like the B120 allowed us to take competitive advantage on the market. We were the first to manufacture 114 mm tubes with an average radius of 125. This machine was fundamental to gain more experience in the bending technology. This was then followed by SWING 32, the first machine with a LH/RH curving direction that was installed in 2000. With BLM we have always had a relationship as partners. BLM have never left us alone when we have had problems and we have always reached useful and valid solutions together. Today we have added three DYNAM0 machines, two of which were purchased last year and operate in the“white”industry and automotive fields. Just to give you an idea: Beyoncé, a DYNAM0-E with automatic loader, produces approximately 1,800 pieces/day for FIAT. A great competitive advantage Unlike other cases where the choice of the lasertube was intended to give production a turning point, at Alpino transition to the laser was simply to keep up with technology. Today, however, pieces that required various steps like drilling, pressing and cutting are now carried out in a single step and this in itself is a great competitive advantage. “Pieces with 8-10 different steps now come straight out of the laser system” continues Gi- Automotive INSPIRED FOR TUBE ampietri. “The laser has simplified production and has allowed us to do things that could not be done before, thereby offering new solutions to our customers. For example, we had a piece that was welded with a screw and nut, but now we do this with lower processing times and without any problem. The laser makes it possible to approach different customers to the usual ones. Many people still have no idea of the potential of lasertube technology, which needs to be explained to customers. Many don’t believe that a laser cut piece can cost less than the same piece processed with a drill and press, that the hourly cost is much less and it’s difficult to convince them, but it’s like that”. Target “euro5” Alpino Industria Metalurgica Ltda has a head count of 240 employees in addition to the 30 operators in the building of a joint venture with a Belgian company operating in the automotive field, where large tubes of up to 120 mm in diameter are processed on a BLM Dunam8 tube bending system. "Of course you can always improve, but obviously our opinion on the BLM Group and its technology is positive, otherwise we would not have bought their machines for the past 40 years, "says Mr. Alonso. "BLM has always given us great technical support and above all they have never left us on our own. People change, but not companies, and most of all the existing close relationship remains.” For the future we are trying to start a second joint venture to develop and manufacture exhaust systems for trucks. In Brazil, the Euro 5 will begin as of 2012 and we are preparing for then, so that we can offer our customers the entire product, not just the pipes. We are building a new 3,000 square metre facility, which will be operational by the end of the year. If we want to grow we need to look for new markets. In the coming years, a 7-10% per annum growth is expected in Brazil, whereas we expect to grow by 20%." The script is written, the cast is exceptional, and the happy ending ... is a must. 11 Väderstad is among the leading names renowned in Sweden for the production Agricultural machinery of tillers and agricultural machinery for ploughing and sowing through a fully automated cycle that starts from the raw material store and ends with the laser cutting of semi-finished tubes and robotized welding INSPIRED FOR TUBE of the machinery produced. At Väderstad, extreme automation is the main tool that binds efficiency and flexibility in the production cycle. More flexibility with automation o describe the Swedish company Väderstad, specialized in the production of tillers and agricultural machinery for ploughing and sowing, we should start from the company’s background. In fact, this family business was founded by the father of the current owners, who have experienced the life and growth of the company first hand, with Andreas Stark, Production Director together with his brothers Crister, Bo and sister Christina, respectively, Head of the Board, Manager of the Scandinavian market and Managing Director, who run the company founded by their father, Rune Stark. T What an idea! While listening to Andreas Stark telling us about the story of the company, you cannot but be impressed by the strong contrast between today’s avant-garde organization, which can boast an automation level in its production that is difficult to find elsewhere, and what it was in the beginning, characterized by such a simple, but effective idea. In fact, Rune Stark, started by manufacturing a 12 MAY 2011 NUMBER 14 13 INSPIRED FOR TUBE Agricultural machinery Agricultural machinery INSPIRED FOR TUBE 14 rigid tine harrow to be used in a small farm at a short distance from where the company is today. The result was so effective that neighbours asked to have others made for them and this was the beginning of the business. The family-run business was therefore set up by Rune together with his wife Siw and it is now run by their four children. “My parents started in our farm – says Andreas – but soon, due to the size of the first pieces of machinery, the poor power connections and the roads that were too narrow for heavy traffic, it was necessary to move to larger premises, which took place in 1967 when the company rented a barn in another farm and in 1972 we started building where we are now”. The story of Väderstad is characterised by continuous growth and started from the idea of a farmer who was particularly able and business-minded. “In the two-year period from 1989 to 1990, agriculture suffered a strong depression, but that was the time for us to expand into other areas of interest starting with the manufacture of seeders, which today account for 60-65% of our turnover”. MAY 2011 NUMBER 14 From the warehouse to laser tube Fully automatically Even from the production organizational point of view there have been many changes, which from the initial artisan phases have gradually brought Väderstad to the extreme level of automation that it has today. The company is structured in relation to the production flow of the materials, starting from a building where the raw material is stored. When a truck arrives, the raw material is unloaded and positioned (semi-automatically) on shelves. At this point, the warehouse is closed and manning is not required. When a job order needs a certain type of material, a request is received on the warehouse computer to retrieve a bundle of tubes; the material is automatically selected and picked-up by the automatic bridge cranes, which place it on trolleys travelling underground that exit the warehouse and transfer the bundle to the building where the laser machines are located; the bundle is then unloaded in a tidy manner near the machines. The ADIGE LT8 laser cutting systems cut the tubes according to the job requirements and unload them tidily. An big robot collects the pieces and places them in appropriate trolleys that are stored in another transit warehouse depending on the job order requirements. Each trolley contains pieces that are required to weld a particular frame. The boxes that are stored in the transit warehouse are then collected and transferred to the welding robots where each frame is physically assembled. Goal achieved “We have a very high number of different products and an even higher number of articles and components in production” continues Andreas Stark. “When we have to weld a frame, we have the items available to make it, but the next one, more often than not, is different; therefore we need to have other articles available. Before purchasing the laser system, most of the tube machining was done in-house, but a part was purchased from companies who used laser systems. Now everything is working and we can proudly say that we have achieved the goals that we had set”. Our strong points are quality and solutions” concludes Andreas. In Sweden, we have an 80% market share, but in the rest of Europe there is a lot of competition. Some of our competitors have laser systems, but no one uses our production concepts. Among other things, it was not easy to find a laser system that was suitable to meet our specific needs; some were too small and others too big. In the end, we found ADIGE who understood what we were looking for and provided us with what we needed to the extent that if there weren’t a recession in progress, we would have had our third LT8. This is because our view of the future is positive in relation to the increase in the price of grain. As to production innovations, we are already thinking about developing products that were impossible to think of producing, whereas at an organizational level, we realize that we can still improve. In fact, in the welding area, no material should be waiting to be processed, that’s why in the future, the cut tubes must arrive directly from the laser machines”. Agricultural machinery way possible. We started an extremely flexible manufacturing cycle aimed at producing a single machine at a time. The goal is now to produce what is necessary for the next shift or the next day. Today is Thursday and we have entered in the production system the output for next Thursday. The raw material is in the warehouse, whereas other articles may not be in our facilities yet and must be delivered by our suppliers, but in the meantime the laser data of what has to be cut is transferred to the system and the parts that need to be welded tomorrow will be in the warehouse tonight. INSPIRED FOR TUBE For this reason, in the past, we had a considerable amount of material spread out around the welding stations, but now it is completely different. The first step was to use a single warehouse with a forklift operator who retrieved the various articles and delivered them to the welding stations. In this way, however, we had an enormous warehouse of cut and machined tubes and when there were errors in the machinings, we had to step in and at times throw away the pieces. It was a slow way of working and, moreover, when you machine a tube that has been cut on different machines, you cannot expect precision. We wanted greater precision to use welding robots and then we wanted to develop our machinery in a completely different way and this was the main reason why we went for laser cutting, which allowed us to process any shape and size. So we started to search for a solution to our requirements and what can be seen now is the end result. A traditional production works in batches, whereas our objective was to produce a single example of a machine in the most efficient “ 15 OFFICE The BLM Group has always focused on proposing something much more important and strategic than a single machine or product, assuring its customers a really efficient production process in which the reliability of its solutions is combined with BLM Group a wide range of dedicated and specific software instruments to bring out the best of it. This is the value guaranteed by the BLM Group; this is the value that makes BLM stand out and INSPIRED FOR TUBE renowned on an international scale. Process efficiency depends on the software fficiency: it is one of the most important characteristics of any industrial production process. Product quality is a characteristic taken for granted and reliability a simple starting point to launch a new commercial product both in terms of supply and procurement. Time loss, material waste, scrap and any other “symptom” of inefficiency within the production process are no longer costs that can burden market prices. Therefore, the “challenge” also regards the organisation of production logics and strategies related to the single processing phases to eliminate or at least reduce whatever is not an added value to the finished product. The BLM Group works with the same logic, but above all proposes and extends it to its customers. All the efforts made to manufacture innovative, quality, flexible and reliable machines would be vain without tools (i.e. software instruments) able to exploit them to the maximum and above all to include each processing phase in a global and efficient logic context. Over the years, the BLM Group has developed in-house software environments useful not only to simplify machine programming, but also for production planning, preliminary checking of single programmes, process sim- E 16 MAY 2011 NUMBER 14 Part Prog Pa ulation and estimation of time and production costs. All the above to guarantee, once again for quality control and most of all process efficiency. From machine programming… To complete its laser cutting systems, ADIGE has developed an in-house CAD/CAM environment called Artube that covers all the advantages already offered by the laser tube during the workpiece design phase and exploits them at the best. The result is, once again, not “only” workpiece quality but also the guarantee of carrying out the entire production within times and with modes that are the most advantageous for the customer. Among the various specific functions offered by ADIGE laser machines we can mention: minimum bar swarfs, optimisation of discharging position in relation to the workpiece length and type, management of automatic cutting technology, possibility of adapting the process to the quality of the raw material if deformed or covered with rust (for example). … to hourly cost estimation once the machine programme has been created, it is necessary to estimate the workpiece Part Prog Lasertube 1 WORKSHOP Artube time and cost. To this end, the BLM Group has designed an additional software system called Part Viewer, allowing a sophisticated graphic simulation to be displayed– again in 3D – of the workpiece being programmed. Thanks to Part Viewer it is possible to preliminarily check the cutting conditions, the settings of each workpiece and, above all, to make an accurate estimation of the cycle time and of the actual hourly production that can be obtained with the machine under those conditions. Part Prog INSPIRED FOR TUBE BLM Group MODELS 2D - 3D Multi-piece lots are not a problem art Viewer Info ProTube Express Job 1 Part Prog Lasertube 1 Job n Info Part Prog Lasertube n A new instrument has recently been implemented allowing to meet the demands of the manufacturers who produce multi-piece lots on their own laser tube and of those who wish to coordinate production with various other systems they have. The new instrument for production planning and automatic programming of multi-piece lots is called Protube Express Thanks to Protube Express it is possible to manage the production of several workpieces in one environment only, to optimise manufacturing by setting priorities and destination (in the case of several machines). The most advanced compacting integrated algorithms (nesting 3D) allow to automatically preset the mode to minimise time and material as much as possible, to obtain a preliminary indication of the number of bars required for each section, to evaluate the choice of various bar lengths and to choose the most convenient one during the material procurement phase. Once the sequence of workpieces to be manufactured has been set on each machine, it is possible to obtain again the estimation of the total time required for the production of the lot, considering loading times, bar changing and discharging times, as well as all the supplementary times related to secondary functions that have been preset. 17 Furniture INSPIRED FOR TUBE The chair is produced by Virco is the largest manufacturer of school furniture for “grades K through 12” which are 5 years old through 18 years old in the United States. Product development has always been the key factor for the growth of a company that believes in automation as a tool for improving the process and not for replacing human resources, which are fundamental to achieve the utmost from each machine. In fact, the union between a skilled operator and a BLM robotized bending unit has revolutionized the production cycle of chairs. hile throughout most of the United States a big snowstorm is creating difficulty,we are in Torrance, near Los Angeles on a splendid sunny day with a pleasant temperature. However, our interest is not in sunny California or the“Studios”, but in a decisively important industrial context; as Jerry Farrell Corporate Director of Technical Operations explains, Virco is the largest manufacturer of school furniture for ”grades K through 12”in the United States. W 18 MAY 2011 NUMBER 14 A leading “family-run business” The company was founded by Julian Virtue in 1950. The first customer was the Los Angeles Unified School District. The company then expanded and acquired a table producer in Conway, Arkansas, followed by the production of chairs and other furnishing articles that are manufactured in Torrance and Conway. Virco has multiple facilities, including its newest lovation in Conway, Arkansas, covering an area of 120,000 sq.m, 40,000 sq.m of which are the manufacturing facilities and 80,000 sq.m of which are the warehouse and assembly shop. Then another two facilities in Conway Cover an area of approximately 25,000 sq.m where compression-molded plastic products are manufactured in one and pre-assembly is performed in the other. Last, but not least is the facility in Torrance that covers 45,000 sq.m and in which more or less the same things as in the Conway facilities are manufactured, excepting a few differences regarding some of the pro- a man-machine union duction processes. As mentioned in the beginning, with 190 million dollars worth of orders, Virco is the leading manufacturer of school furniture for “under 18s” in the United States. The company is still family-run. Bob Virtue, son of Julian Virtue, is the current President, CEO and Chairman of the Board. Bob’s son, Doug Virtue is Vice-President. Both believe in the fundamental values that have no doubt been handed down from father to son: voice, dignity, equity, leadership and merit. Not by chance, Virco has led the school furnishing industry in the certification field for emissions as regards quality of indoor air, being the first company to obtain the Greenguard® for Children and Schools indoor air quality certification for classroomfurniture. From five to a single process Customers who contact Virco turn to them for quality and, needless to say, for price. As to quality, what is intended is also the ability to offer a vast range of products.“We offer many different solutions such as colours and styles to meet the market demands”, explains Jerry Farrell, who guides us on the visit through the company. “Our market has changed considerably over the years and we are not the type of company who imports the whole product from China, although we are aware that some of our competitors do. To resort to increasingly lower costs is not our job, but, on the other hand we always try to find the best compromise and this is why we have chosen a BLM tube bending machine that meets our requirements in terms of flexibility and quality”. “One thing that I strongly encouraged in our facility right from the beginning was automation with the use of robots in the assembly process and generally throughout the facility”. “I took this road 17 years ago by installing the first welding robots and today we have more than thirty operating robotized stations. The BLM machine was delivered in 2008 and, it revolutionized our production process”. “Generally, we take the most difficult components and put them on that machine because we know that with only a few attempts we will be able to achieve a repeatable result”. “When we purchase new machines, we do it with the aim of improving the process. I can give you an example of a chair that we make in three different sizes”. “Before purchasing the BLM bending unit, five different bending processes were necessary. It was probably the most complex article that we had ever bent. Now with the BLM tube bending unit, we can do it in one single process”. “When selecting a machine, the decision is well weighed out and assessed. What follows is a very close relationship, almost like a partnership with the machine supplier leading to longlasting cooperation, which is what has hap- 19 Furniture INSPIRED FOR TUBE pened with the BLM Group” . “When Virco purchases a new machine, the selection is not made on the basis of the cheapest price alone, but it is made according to the possibility of it being inserted in the production process that we intend to implement. Important features, such as programming ease and after-sales service/technical assistance are evaluated. Automation without doubt, but managed by man As regards competition with the markets like China and others that are growing such as Thailand and Vietnam, Virco strategically focuses on three main issues: good service, good quality and the ability to meet the customer’s every need with new products. “When a customer requires new articles, we are able to respond very quickly,” emphasises Farrell.“At the end of June, a school requested a completely new product for delivery by the beginning of August. We designed, manufactured and supplied it in less than two months. 20 MAY 2011 NUMBER 14 To achieve these goals, it is fundamental to have the right people. If not, then there is very little you can do. Therefore, automation at Virco is not to be understood as a way of replacing human resources, but of improving the process and to do so competent people are needed”. This is the reason why we put our most difficult pieces on the BLM tube bending unit, as we have skilled people who know how to operate the machine and are able to manage the product”. Production is carried out mainly at the Virco facilities seeing as there are various divisions, however, there are still some small jobs that are outsourced. “Some parts of our products are laser-cut” – continues Farrell – but before thinking of installing such a system, I have to have the right people. Today, the problem of outsourcing lies in programming; if you want to run a just-in-time production to meet the customer’s demand precisely when required, outsourcing creates a problem. Of course, there are also advantages, but with the increasing flexibility of the machines, we should aim at doing more in-house and outsourcing less. In the future, we should, therefore, invest in the process”. Virco considers the assistance that it offers its customers of utmost importance, starting from the support offered to school managers for purchasing furniture on a large scale, thereby saving time and money, and continuing with scheduling collection to recycle the old furniture. Our program “Cash for Cardboard” has allowed the school community in the Conway area to recover more than 100,000 dollars through recycling. We at Virco are proud to be renowned for our continuous commitment towards quality, which includes employment and the environment”, concludes Farrell. Laser tube has a fundamental role at MDL. The company is an OEM and as such spans the most different of fields although, in recent years the manufacture of structures for solar centres has been taking on a leading role. In particular, the decision to install an ADIGE LT Job Shop panel systems and couches for shops and go unscathed through the difficult economic situation of the last two years. INSPIRED FOR TUBE 722 system has allowed the company to The good thing about the lucky choice DL (acronym of Marcello Diego Lavorazioni) of Capriano del Colle located in the province of Brescia is a company that has been specialised in commercialising steel products since 1989, with special regard to contract tube processing. In recent years this sector has increasingly evolved from the simple cutting-to-length to the supply of quality semi-finished products including the manufacture of assembled structures, thanks to the cooperation of a specialised partner. As a result, MDL proposes itself as a supplier of actual finished products that it manufactures with the knowledge of who has analysed the multiple potentials and opportunities offered by tube processing in terms of project and structure optimisation. A tubular structure assures many advantages compared to a structure designed by mixing tube and bent steel sheet, both in terms of coupling and sturdiness, not to mention production time and associated costs. “MDL is certainly the answer to the requirements of all those companies that require com- M 21 INSPIRED FOR TUBE Job Shop plex services in the filed of steel product processing, with special reference to tube transformation” explains Marcello Zanini, who runs the company together with his brother Diego.“We supply semi-finished tubes to any sector and our activities also include welding or bending of tubes as well as the manufacture of drawn tubes, round, square or rectangular welded tubes with burrs on the two sides. The services offered also feature internal and external washing, customised drilling and processing of round, oval or square tubes or simply the cuttingto-length of tubes and bars”. 22 90% production within 150 mm diameter The equipment installed at MDL facilities includes six ADIGE automatic sawing machines, but above all it is the laser tube cutting technology that characterises the activity. The first laser tube installed over more than three years was associated with the innovative LT 722 ADIGE system in 2008. “Both in terms of plant type and ease of programming I can state that ADIGE represents the state of the art from a technological point of view” says Marcello Zanini. “In our first experience with laser tube we privileged the cut potential in terms of maximum processable dimensions up to a diameter of 250 mm. On the other hand, with ADIGE’s LT 722 we process up to a maximum of 150 mm; a range which covers approximately 90% of our production. “In hindsight”, the initial choice of large diameters has been more restrictive than proactive. MAY 2011 NUMBER 14 It is true that where large workpieces are cut, the small ones can be processed as well, but from the point of view of system performances, by nature they are not comparable. Certainly, today, with two systems available and a third one coming up, equipped with fibre laser to cut highly reflecting materials, we are in a position to cover a very large portion of market demands”. “Perhaps we have made the right choice to invert investments considering that the majority of the work regards the medium-small tube; but that’s ok. The in-field experience has allowed us to focus on what we really needed and to correct the course” explains again Zanini.“In fact, by purchasing the ADIGE system we have privileged other aspects that we knew were of fundamental importance, such as the programming ease which, in the majority of cases, means the possibility of carrying out complex cuts as well. The standard database of the LT 722 cutting parameters is extremely complete and articulated to the point that in the vast majority of cases we can immediately carry out an optimum cut”. A “tutor” by your side Due to its nature, MDL addresses various sectors: automobile, water-sanitary, heating, furniture, components and drapes. The company is a job shop and as such it spans the most different of fields although, in recent years the manufacture of structures for solar panel systems and couches for beauty shops and centres has been taking on a leading role. “Following the crisis of the last two years, we The LT 722 combines productivity with the utmost cutting accuracy on any type of tube section, which is of fundamental importance for coupling, considering the structures being manufactured. “I think that we have been lucky to purchase this laser tube system before the crisis” continues Zanini.“It has allowed us to make up for desertions that have occurred in the most traditional sectors, and to acquire new customers and new application fields. Above all, however, it has allowed us to recover important trade names that we had lost due to rather long response times and to the excessive hourly cost with only one laser tube available, that, moreover, is more performing on larger diameters. Due to the inherent characteristics of the LT 722 and to the availability of two laser cutting systems, today we have acquired such a flex- “It is like working beside a tutor, since if cutting passages are set with the risk of colliding or require conflicting motions, the machine does not carry out the functions and signals the error”. The laser semi-finished product is a finished product Of the quantity of material processed by MDL over a period of a year, 60% is distributed among the sawing machines and the remaining 40% among the two laser tubes; these percentages witness the importance and strategic role of investing in a technology that is as productive and flexible as laser cutting. This fact is further confirmed by economic evaluations considering that the business turnover produced by the laser is by now predominant compared to that generated by the sawing machines. Costs are soon worked out considering an hourly price of 30 Euros for blade cutting as compared to 80 Euros per hour of laser cutting. “There is also the advantage that with the laser, the semifinished product is a finished product ready for assembly while the sawing machine allows just the cut-to-length involving the need for deburring and recovering the workpieces” Zanini concludes. “Furthermore, I admit that from time to time I have some simple and particularly urgent cutto-length operations carried out by the laser machine because the LT722 produces twice as much compared to a sawing machine as there is no blade changing and therefore no down times. Not to mention the cut quality that has no deburring and accuracy problems. Not by chance, we are replacing two sawing machines with a new LT FIBER laser tube system with fibre source that we believe will allow us to open up new and important horizons in the field of copper and brass tube cutting.” Job Shop I bought the equipment in July 2008 and it was installed in September; since then it has not stopped, not even once.” ibility as to reach a production close to the justin-time, with a lower hourly cost than before. We wanted to become flexible also in the laser cutting field as we have always been in the blade cutting field thanks to the six ADIGE automatic sawing machines. I talked about luck because although it may seem a farsighted decision taken at the right moment, I am sincere in telling you that it is not the case. We needed and we decided to take this step, but when it was planned I never imagined what would have happened in such a short time. I considered it a strategic investment that was important for MDL, but never thought of it as the company safety net. However, this was the right choice because if I had realised about the crisis that was about to hit the economy, I would have certainly waited and perhaps we would have ended up like several other companies.” “Flexibility is mainly generated by the ARTUBE programming software that is extremely userfriendly and direct, but also by the operating software of the LT722 system allowing rather fast production changes and therefore machine downtimes that are considerably reduced” Zanini adds. INSPIRED FOR TUBE have been obliged to considerably extend our operating range to cover new sectors in order to recover that 20% business turnover that we had lost” explains Zanini.“It has not been easy, but we have been able to count on a sound partner: the ADIGE LT 722 laser cutting system that is one of a kind in terms of performance and timing. Among other things, the almost total reliability. 23 OEM INSPIRED FOR TUBE The company takes its name from its founder Rubino Andreazza. Or rather, it takes part of the name and part of the surname since Rubizza is a perfect mixture of the two. However, Rubizza is also a perfect combination of the typical characteristics of the entrepreneur: passion for work, farsightedness, ability to make important decisions and the courage to take action also at less appropriate moments, even forcing the situation for a fundamental investment. The small lots strategy n 2003 the first laser tube installed at the company facility was the ADIGE LT702, which also holds the record of being the first BLM system sold in the region. The purchase of this machine was difficult considering that the investment was very binding for Rubizza at the time. Until then, the machines they had were simple tube bending machines and investment in the laser technology was a big commitment. However, Rubino Andreazza had understood the situation and with the support of the BLM Group made the big step proving to be a winner. I The partner supplier To hear the company history told by Mr. Rubino Andreazza is exciting.Together with his wife Vainer Pagliarin Andreazza founded Rubizza in 1992 and made of it a company that today employs 35 people and is becoming increasingly important in Brazil. “We started in a 100 sqm room where we 24 MAY 2011 NUMBER 14 moulded accessories for furniture. In 1996 our products were no longer commercialised on the market.Therefore, we started to bend tubes with a first “CNC” machine that was very simple.Thanks to this machine however, we gained the know-how and experience in the tube sector that proved fundamental to make us 100% job shop and penetrate other markets. We are looking at 1998 and from then on our company history, with the purchase of a first NC863 tube bending machine that allowed us to work for the agricultural machinery and automotive sectors, starts cooperating with the BLM Group. We put our bets on them and focused everything on product quality. A partnership relation was built up with the BLM agent, who help us to start-up and find work to operate the equipment. Therefore, the cooperation has been an important factor; in fact today we have eight BLM machines, among which the laser machines in particular that have completely changed the operating mode and the production cycle. BLM is a partner for Rubizza. “When we were in need, we always received assistance and support”, Mr. Rubino states. High quality focus When the building facility was changed in 1999, Rubizza made another basic step in its growing and expansion process that in 2001 was confirmed with the purchase of a BLM SWING tube bending machine with R/L bending direction allowing to process also small and complex workpieces. However, this meant the passage from a simple bending to an automatic bending, that involved an important technological change. The most courageous and strategically fundamental step was made with the LT702 laser in 2003.“The laser was a challenge – says Andreazza – and after many years I can say I won. With the LT702, work has increased adding more important and demanding customers. OEM INSPIRED FOR TUBE The laser tube has allowed us to simplify work in as much as presses and dies are no longer required, not to mention the ease of manufacturing that facilitates a just-in-time production management. Finally, we are able to manufacture complete pieces with special joints that we could not produce before.” The company growth is confirmed by the regular frequency with which machinery is purchased. After the first laser, a second SWING tube bending machine was purchased. Then, from 2007 to 2009, another two new-generation tube bending machines were purchased. First a DYNAM0 ELE was purchased, and then an ELECT-L for tubes up to 80 mm in diameter, both all-electric machines. To end the cycle, in 2009, the second laser system was purchased: an LT8 Laser tube with 3D head designed to cut up to 220 mm diameter tubes. This equipment has made it possible for us to have job orders in the field of agricultural equipment and trucks. Unlike what usually happens, the Rubizza laser history started off from the tube and only later did it cover steel sheet. In fact, two years ago, they also entered the flat laser sector to expand their range of action and di- versify market outlets, considering the large steel sheet demand. Today customers look for quality, precision and respect of delivery times. It is not by chance that Rubizza is a reference point also for the S. Paulo area. Today, they have no competitors but partnerships with other companies of the area since they focus on top quality. Rubizza does not refuse mass production, but prefers small lots to further confirm the entrepreneurial farsightedness of Mr. Rubino. This is, in fact, a strong point in a world where many refuse small quantities in favour of large ones.“Now there is no specific sector, we work a little for all sectors with small lots thanks to which the company has been able to grow. Obviously this requires high flexibility” concludes Rubino Andreazza. 25 Elevated work platforms and walkways. This is the product whose leading worldwide Elevated platforms producer is Premekon, a Finnish company that combines its engineering technique gained and refined on the field with its INSPIRED FOR TUBE advanced technology and production means. The introduction of the laser tube and of a modern tube bending technology has significantly contributed to improve engineering solutions. From laser to new en he Finnish company Premekon is specialised in the manufacture and marketing of elevated work platforms and walkways supplied as a finished product complete with stairs and storage space. Characterised by top quality and absolute reliability, these products are the result of advanced production methods during implementation and of an engineering skill that is one of a kind. The company was established in 1984 as an engineering office specialised in the production of welded structures and only in 1991 did production start. This was of great advantage since it allowed to experience first hand and analyse the engineering and production problems of various sectors. Competence and know-how are the basis of success. “We have never been just a simple workshop - says Martti Immonen, Managing Director of Premekon - but something more, thanks to the engineering part. T 26 MAY 2011 NUMBER 14 Today 12 out of 45 people are specialised engineers to confirm the importance that we give to the development and engineering phase of our products.” Substantial project differences The fact that the use of laser tube is a strategic turning point for the activity of any company no longer makes the headlines. However, in the case of Premekon it is worth pointing out once again as laser has brought important advantages in terms of productivity (before the laser, traditional tube processing methods were in use), but above all of new product engineering opportunities. “When purchasing a laser system we basically expected two types of advantages” explains Mikko Polkki, Production Manager of the com- pany.“On one hand, being able to concentrate tube processing operations on a single machine and on the other, obtaining a higher efficiency during the welding and assembly phases downstream. We not only thought about the cutting phase when improving accuracy and efficiency (approx. 25/30% increase in production), but also and above all about the processing phases that follow. Laser introduction, with an LT Combo system to cut tubes and steel sheets has also allowed to differentiate production. Previously, 90-95% of the production consisted of walkways, stairs and storage areas; now this figure is reduced to 80%. The remaining 20% is accounted for by contract work for various tube users. Generally, we work with reduced workpiece lots and our main characteristics, more today than yesterday, is flexibility.” “As compared to the past, introduction of the laser system also involved the modification of INSPIRED FOR TUBE ngineering solutions single components; the workpieces look the same but to the contrary they have some substantial engineering differences exploiting the possibilities offered by modern laser technology in terms of new and better combinations of structural elements” says Veikko Olkkonen, Research & Development of Premekon.“The LT Combo system has allowed us to widen our view regarding the processing possibilities; among other things thanks to BLM's CAD/CAM ArTube it is very easy to create programmes and the results are immediately visible on the machine. Customers noticed and appreciated the modifications carried out following the adoption of the laser system that has led to more precise and accurate products”. Handrails in one process only The laser machine was installed in December and after only a few months, in April to be precise, a BLM ELECT-L tube bending machine was installed.“I have known the BLM Group since University and I knew that no other company that had such experience in tube processing” explains again Martti Immonen, Managing Director of the company. “Automation, by increasing the production process efficiency, allows to reduce prices making them still competitive. In the future, automation and high-tech will be increasingly important to improve efficiency of the production process and to control production costs in relation to market demands.That’s why the choice of making another important investment was made after only a few months. The tube-bending machine has allowed to modernise our production process thanks to an advanced technology allowing to manufacture stair handrails in one step only adding just the angles with one weld.The most outstanding features of this machine is the operating speed and the capacity of manufacturing quality radii, again with a positive influence on the possibility of studying and designing structures with details and components that were unthinkable in the past without the laser and tube bending machine. For example, we manufacture many handrails in aluminium that we cannot cut with laser (we could, but it is not recommended) and we make many handrails for the building and construction sector”. Automate to compete “Low cost competition among countries exists, but with products that anyone can manufacture”concludes Martti Immonen.“The difference lies in what not everybody is able to manufacture. Quality and engineering are therefore our strong points. In the future, automation and high-tech will be increasingly important to improve efficiency of the production process and to control production costs in relation to market demands”. 27 Landoll is specialised in the construction of agricultural machinery, and over the years has added the production of trailers, forklifts and INSPIRED FOR TUBE Agricultural machinery equipment for military purposes. Product diversification, direct control of the whole production cycle and above all a deep knowledge of the customer’s problems are factors that, together with the use of a more advanced lasertube technology, make Landoll a leading company in each of its fields of activity. The advantage of being born on a farm gricultural machinery, trailers, forklifts and military equipment. These are the production sectors in which Landoll is divided; a company created in 1963 by Don Landoll, Owner and President of the company who tells his story: “I was born and grew up on a farm, and ever since I was a child I liked welding and building objects and metal structures. I started off repairing agricultural equipment and machinery. Then, after school, I worked for three years in a company specialised in the manufacture of equipment for parks and farms. That was my first industrial experience. In 1963 I set up my own welding facility for contract work. I A 28 MAY 2011 NUMBER 14 employed one person only and so it took some time before starting to launch a range of products of my own. The business I built now consists of 670 employees distributed in several production facilities.” Leader in all sectors “Our strong point is product diversification – continues Landoll – and the capacity of implementing it in-house. We buy the raw material and manufacture finished products with a low degree of outsourcing. In fact, we have a well-equipped facility to produce whatever is required. It is a very important aspect, especially today where absolute control of the production process is required, expecially in the field of agricultural machinery.” Landoll explains how just-in–time-production requires a production capacity that is independent of any supplier. We are of the berlief that no-one can make our parts better than ourselves. By outsourcing work we risk the chance of creating potential competitors” concludes Landoll. His products are known for their high quality and are positioned in a definitely high market segment.“Product know-how is another strong point of our company” explains Don Landoll. “We maintain our own farms and know very well what jobs must be carried out by our machines, which helps us to develop products Agricultural machinery INSPIRED FOR TUBE that meet the demands and expectations of our customers. Also from a sales point of view, our sales people must have a thorough knowledge of our products in order to communicate the added value that we are offering to potential customers.” An 18 m long bet In such a complex reality – including eight Landoll production facilities – the use of advanced technologies is of fundamental importance and the lasertube is an integral part of this mechanism. A Jumbo and an LT8 are the ADIGE systems installed and used to cut all the tubular com- ponents of the company’s various products. “I came across the BLM Group at Fabtech in Chicago – says Landoll, and I was looking for the best way to further improve the manufacture of our products. Since we live in a small community, we must all do our best to increase production with the minimum amount of manual work. First of all, labour is expensive and not easy to find. As a result, we decided to buy the LT JUMBO. We needed a machine that could do everything. A smaller machine could have been faster, but would not have met all our requirements. Initially, we bought a 14” system; then we were offered a 20” system that was 29 Agricultural machinery INSPIRED FOR TUBE immediately available and we purchased it with a view to buying a smaller machine later, as soon as we were able to fill it up. derstood the significance of having a machine designed to do whatever we desired in automatic mode” points out Landoll. With the quality level of our products, we are constantly seeking efficient manufacturing methods. From this point of view, we certainly took a bet with the LT JUMBO, mainly as far as the maximum length of the machinable tubes (47 feet) which is as important as the maximum diameter. “The greatest surprise that we had with the LT JUMBO is that, in the end, it is as fast as smaller machines. The jumbo processes a huge quantity of tube in a 24 hours a day, five and half days a week.” Our objective was to obtain the maximum length possible and to machine tubes up to 18 m length so as to produce with a higher efficiency without worrying about cut-offs. At Landoll we had already gained a certain experience in tube cutting. The experience was achieved on a steel sheet cutting machine equipped with an additional module for tube machining in which we had to manually load one workpiece at a time. “Due to this experience, we immediately un- 30 MAY 2011 NUMBER 14 Ally of robotised welding The LT8, purchased some time after the LT JUMBO as initially planned,is appreciated for its speed and excellent cut quality, as well as for its loading and unloading features.The presence of the single bar semiautomatic loader in addition to the conventional bundle loader located at the rear makes it ideal for the several single parts to be cut. “It is a very useful and efficient configuration” points out Landoll who continues to refer to laser systems in general:“We have gained advantage in manufacturing components that required 90° junctions that can now be carried out with more accuracy and in a different manner so as to facilitate and speed up welding.We now have the capability to efficient produce holes, slots and other features on a tube in a single process ”. One of the best features of the LT8 is the steady rest being positioned close to the cutting head. This helps to guarantee the required precision for automated welding. The facility includes 20 robotised welding units that can be used only if there are precise components. Thinking about future investments, Landoll states:“First of all it is necessary to be able to seize the opportunities with quality products. All customers want reliable and easy to use products. Of course, cost is also important and efficiency in production must be taken into account. At present, our sales exceed our production capacity. We must therefore increase our production response and control costs and manual that is quite considerable”. Certainly, Landoll shows his appreciation for the BLM Group products and in particular for laser technology. As for the future, he is rather optimistic, expecting further investments to be made in laser systems designed to operate in the LT8 and LT JUMBO dimensional ranges.
