LISSMAC AND KUHLMEYER FORM AN ALLIANCE FOR THE FUTURE
LISSMAC Maschinenbau GmbH from Bad Wurzach, Germany and Kuhlmeyer Maschinenbau GmbH from Bad Oeynhausen, Germany agree: Together we are stronger and can better serve the market for sheet metal working machines. Since July 1, 2023, both companies have launched a sales and service cooperation in which LISSMAC co-represents and services Kuhlmeyer solutions. Since 2003, LISSMAC have been setting standards in the processing of two-dimensional plate material and sheet metal with a range of specially developed, patented steel brushing, grinding and deburring machines. In particular, LISSMAC machines for double-sided processing of internal and external contours in a single pass are in high demand, as they save both processing time and energy costs compared with single-sided machining. Kuhlmeyer on the other hand can look back on fifty years of innovation and specializes in machine construction for surface finishing, deburring, weld seam preparation and edge bevelling of three-dimensional sheet metal workpieces or large-format plate material. "What unites LISSMAC and Kuhlmeyer are the same values and similar corporate philosophies" says Daniel Keller, Managing Director of LISSMAC Maschinenbau GmbH. "We share the same solution focus and continuously strive to optimize our machines. The customers and their needs are always our highest priority." LISSMAC can rely on a worldwide network of dealers and a broad-based sales team, thus opening up new markets with Kuhlmeyer products. "Through the sales and service cooperation with LISSMAC, we can gain more proximity to the customer and serve markets more efficiently," explains Ralf Wallmeyer, Managing Director of Kuhlmeyer Maschinenbau GmbH. To underline the cooperation, both companies will exhibit together at Schweissen & Schneiden, the world's leading trade fair for joining, cutting and coating technology, which will be held in Essen, Germany from 11 to 15 September 2023. Interested parties are warmly invited to get to know both companies and find out about their product and service portfolios. Solutions for processing plate material, sheet metal and three-dimensional sheet metal parts will be presented in Hall 6, Booth 6F20.

New Grinding And Deburring Machine For The Deutsche Bahn Bridge Workshop
The DB Bahnbau Group is the full-service provider for railway infrastructure. In the bridge workshop (Brückenwerkstatt) in Dresden, almost everything revolves around steel railway bridges. In order to be able to operate economically and in line with quality standards, the bridge workshop invested in new plant technology. Text: Annedore Bose-Munde The Brückenwerkstatt Dresden specialises in the design, manufacture and assembly of steel and bridge construction. The portfolio includes everything from the planning and manufacture to the installation of bridges, steel structures, construction aids and railway embankment culverts. Against the background of increasing quality requirements, the topics of rounding and edge breaking have become increasingly important in recent years. At a sharp edge, the corrosion protection system breaks down first and. the longevity of the engineering structures must be ensured. Manual editing cannot reliably guarantee reliable and repeatable quality. Roland Möbius is responsible for cutting and says at the Brückenwerkstatt Dresden: "In 2018, a new DB Netz guideline came out that is based on EN DIN 10/90 -, a European standard that is generally valid for static load-bearing components. The internal standard regulates the preparation and further processing of welded products, e.g. the degree of purity of the sheet metal and how the edges are to be rounded. Here it is required that all edges with radius 2 mm should be rounded." Reliable edge rounding with radius 2 This was the specific point where action had to be taken. Up to this point, deburring and edge rounding was mainly done manually. A technical solution had to be found. There was also the issue of employee health, as the strenuous and repetitive nature of the work was compounded by the dust generated by grinding. "We knew that we wanted and needed to change something. So we gradually started looking at filleting machines. We clearly defined our requirements for the new machine and looked at what machines were available on the market," says Uwe Träber. He is the workshop manager and thus responsible for the execution of production and the machine processes. After a great deal of research, the bridge workshop sent samples to a number of equipment suppliers, where the appropriate tests were carried out. And finally, they also consulted a business partner - Mende Industrieprodukte e.K. from Wolkenstein in the Erzgebirge district of Saxony. The company advises on abrasives, deburring and polishing agents, stainless steel and surface technology, aluminium, copper and brass processing, and then supplies the components, -as it did for the bridge workshop in Dresden. Kerstin Kunze, owner of Mende Industrieprodukte, looks after the abrasives here. So she also knew the topic of edge rounding 2 mm, which came up again in 2018. Kunze also works very closely with Lissmac Maschinenbau GmbH in Bad Wurzach and has thus also been able to establish contact with the bridge workshop. Discussions on the requirements for the parts will take place in 2019 and the first parts will be machined in 2020. How should the processing be done? Should it be machined on both sides or on one side? Is the result of the rounding good? Which of the Lissmac systems can best meet the requirements? Kerstin Kunze and Dirk Schürstedt shed light on all these questions with a view to the sample parts of the bridge workshop. "We then made a recommendation for an SMD 3 P edition. The universal grinding and deburring machine was specially designed for thick sheet metal processing and delivers very high performance in edge rounding up to a 2 mm radius due to maximum tool contact with the components. In addition, the upstream mechanical removal of slag from plasma and oxyfuel cut parts is effective and reduces tooling costs," says Schürstedt. He is Area Sales Manager Metal Processing at Lissmac. And Schürstedt also mentions a challenge that had to be overcome in the whole decision-making process: "The trials took place as the pandemic peaked. Due to Corona restrictions at the time, personal visits were not possible. We presented, discussed and clarified a lot online. The actual part machining, however, took place on site at Lissmac. The parts were then shipped for that." Results of the sample edits were evaluated All sample processing results were evaluated by the in-house quality assurance department. The DB Bahnbau Group, and thus also the Brückenwerkstatt Dresden, ultimately opted for the recommended SMD 3 P edition, i.e. for the machine that best covers the requirements portfolio. The plant was delivered in December 2021 and commissioned in January 2022. Andreas Naumann has been head of the Brückenwerkstatt Dresden since January 2022 and is responsible for the Brückenwerkstatt as a whole. He is satisfied with the decision to use Lissmac technology. "The overall concept, both technically and commercially, fits. In addition, Lissmac is a reliable partner, also with regard to service," he says. One thing is certain: What the Lissmac machine does today was previously done manually-, with a lot of manpower and material. The aim was to automate processes to make them faster and more economical. In addition, the high cost of personnel was to be reduced and the quality to be mapped was to be comprehensible. All this has been achieved. Roland Möbius, in whose area of responsibility the machine is located, says: "Our employees confirm that the use of the new grinding and deburring machine makes their work much easier: in terms of dirt, in terms of reduced noise and also in terms of processes that now run more efficiently". Andreas Naumann underlines this: "It's faster, the quality is very good and comprehensible. In addition, preliminary processes such as edge rounding have always been a bottleneck for us. So the increased output also helps us to organise the whole process better. To further optimise the process, a student trainee is currently investigating the individual system and process parameters. Traditional Company Is Well Positioned Questions in the start-up phase could be clarified quickly. "The sheets that are processed vary in terms of height or curvature, for example. Here it is important that we have gained experience and were able to get information from Dirk Schürstedt and Kerstin Kunze," says Uwe Träber. It is mainly steel parts that are machined in a wide range of dimensions, starting with parts of approximately 100 mm x 100 mm up to dimensions in the range of 2 to 3 metres. These are both individual parts and small to medium quantities. "Our utilisation rate is very good. Our employees are satisfied. The spectrum on which we work is dependent on the task at hand. We act in a completely flexible and variable way. These are almost always individual parts. Their shape and dimensions are unique. Whether web parts for girders or bulkheads- from the door handle to the entire bridge, we can process everything," Naumann gives an overview. DB Bahnbau Gruppe GmbH, to which the Dresden Bridge Workshop belongs, is a subsidiary of Deutsche Bahn - the Dresden site is a department of the Special Construction Division. The DB Bahnbau Group employs around 3,600 people in Germany; there are more than 100 in the Dresden bridge workshop.
LISSMAC presents grinding and milling machines at EPF
For the twelfth time, the flooring industry met from June 22 to June 24, 2023, to experience what is state-of-the-art in the fields of screed, parquet and tile. Around 150 exhibitors - including many first-time exhibitors - presented strong machinery, aggregates, products, accessories and services for screed, screed laying, floor coverings, floor finishing and tools to around 4,400 trade visitors in an exhibition area covering approximately 10,000 m². Expert lectures and two evening events, as well as the presentation of the German Screed Award, rounded out the trade show offerings and once again made the trade show attractive for numerous trade visitors. A high presence of decision-makers in the industry is also shown by the result of the exhibitor survey: around 75% of exhibitors were not only able to present their products and cultivate existing customers during the trade fair, but also to establish promising new business relationships. "Especially the high quality and the competencies of the trade visitors were fed back to us by the exhibitors in the first feedback rounds as very positive," says the managing director of the Bayerische BauAkademie, Dipl.-Ing. FH Gabriela Gottwald. "Many first-time exhibitors were also surprised by the high number of trade visitors and decision-makers at the fair, and we already have initial bookings for the next Estrich Parkett Fliese trade fair." [Excerpt from the official press release of Bayerische Bauakademie] LISSMAC was also there for the first time this year to present the grinding and milling technology newly added to the product range. After the machines for floor preparation were already well received by visitors at bauma 2022, we took the opportunity to exhibit at a trade fair specifically for this sector. Our booth was rounded off by some classics: floor saws, core drilling equipment and our LIBELT conveyor belt - equipment that is also used in demolition and building renovation. The live demonstrations in the open area of the site were particularly well received. During the entire process from initial information to the purchase decision, seeing and experiencing the products offers an enormous advantage. We at LISSMAC attach great importance to this. For this reason, we are offering training days for grinding and milling machines and floor saws at our Beckum site in September. Further information will follow. Click here for the assortment.

Trip to the cheese dairy Vogler
If you become part of the LISSMAC team, you can expect not only exciting and varied tasks, but also numerous benefits such as joint activities with colleagues. A career at LISSMAC is fun! So on Thursday, March 30, 2023, after work, we visited the Vogler cheese dairy, the best-known cheese dairy in the area. After we were all dressed in hair hoods and coats, we were given a tour by the cheesemaker himself. He initiated us into the secrets of cheese making and explained the production and storage process of cheese. We learned more about the differences between hard, semi-hard and soft cheese and were then allowed to taste the different varieties. In total, about 20 different varieties are produced, depending on the season! From mild to spicy, there was something for every taste. So in the comfortably furnished Sennerstüble a common get-together was guaranteed. As always, it was a successful excursion, so that we are already looking forward to the next joint activity with our colleagues. If you would like to be part of our team, apply now!
Resource Efficiency, Low Power Consumption And New Business Fields
Quality and functionality are also important and are arguments for investing in machinery and equipment. But the reliability of the machine builder, speed, flexibility and uncomplicated hands-on cooperation are often just as decisive for a new acquisition. When purchasing new grinding and deburring technology, a company from the Ammerland region relies on precisely these classic SME values. Text: Annedore Bose-Munde The expertise of Wiechmann Ketten- and Kettenräderbau GmbH from Edewecht lies in two areas. On the one hand, this is chain production. Wear parts for trenchers and other applications are manufactured here, for example milling chains, sprockets or digging tools. In the second competence area - of sheet metal processing - everything revolves around laser cutting, forming as well as deburring, edge rounding and grinding. The company was founded in 1963 by the current senior, Otto Wiechmann, and began with the production of wear parts for cable trenchers, later adding chain production and in 1999 sheet metal production. Today Wiechmann employs 55 people. About half of them work in sheet metal production. Here, production is carried out for a wide range of industries, such as the food and packaging industries. About 10 per cent of the parts are manufactured for the company's own products in chain production. These are mostly parts that have to be touched by hand. Quality, reproducible results and efficiency For Andre Wiechmann, the company's managing director, safety is an important issue. "We wanted to move away from hand deburring. The risk of injury should be minimised. In addition, the quality requirements of our customers have continued to increase in recent years. In addition, the power consumption of the plants should be reduced and the efficiency increased," he looks back at the starting point of the considerations. These criteria are also important to Hinrich Böhlje, who joined Wiechmann in 2015. Looking back, the sheet metal production manager says: "At the time, we had the Lissmac SBM-M 1000 S2, which we bought in 2006, and two other machines for rounding edges. The other two plants consumed a lot of electricity. Moreover, these did not have the option of machining the parts on both sides. So there was always a need for reworking or a second operation. And with the Lissmac system at the time, it was only possible to process sheets with a width of a thousand. But we also cut parts up to two metres wide." So the decision was made to invest in new plant technology. The focus of the project was to increase efficiency through double-sided machining, to cover a wider range of parts and, of course, to reduce power consumption. Managing directors Andre Wiechmann and Hinrich Böhlje were already convinced of the reliable technology of the Bad Wurzach-based company. In 2017, an SBM-XS 300 was purchased for machining small parts - designed with a vacuum belt for parts made of stainless steel and aluminium. And so the machine manufacturer from Upper Swabia was also on the selection list when it came to new investments. In addition, production manager Böhlje knew other Lissmac plants from a previous job. Quick decision and adapted project planning process In the spring of 2018, Andre Wiechmann, who took over responsibility for the company from his father in 1996, made a decision after visiting a trade fair. He contacted Lissmac and the project planning procedure could start. "We have sent a large number of parts to Lissmac in Bad Wurzach for trials. And we were also there ourselves. In general, we are very close to the customer with all our products and that's what we wanted to be with the new machines," he explains. The process and the coordinated project planning for the plant took about a year. As a result, two SMB-L 1500 G1S2 sanding and deburring machines were purchased, each with an infeed and outfeed belt. This means that parts up to four metres long can also be machined on both sides. With the acquisition of the two SMB-L 1500 machines, the SMB-L 1000 was then sold and the other two grinding machines were also disposed of. "The decision in favour of Lissmac technology was made relatively quickly," says production manager Böhlje. "On the one hand, the positive experience with a comparable plant was already there. On the other hand, there were not so many manufacturers offering double-sided machining. Last but not least, the systems are highly flexible. So if Wiechmann's products change, the units can be changed quickly and easily". The option of adding a second machining unit now saves 50 percent machining time. In addition, only one extraction unit is required for both systems. In addition, the SMB-L 1500 has an upstream unit with sandpaper. In addition to enabling double-sided processing, this also helps to ensure efficient workflow. For managing director Wiechmann, it is also important to separate the materials and thus ensure that they are processed according to type in production. For example, one of the new grinding and deburring machines is used only for stainless steel and the other for mild steel. "With machine deburring, we can now ensure efficiency in machining and guarantee reproducible machining results. These are also important sales arguments in sheet metal production," he says. Aluminium Machining And Explosion Protection The two SMB-L 1500s were delivered in June 2019. The second SBM-XS 300 was ordered directly with the delivery. Hinrich Böhlje tells the story behind this second small parts machine: "We were asked to produce rounded-edge aluminium sheet parts for a customer. So far, these have been lasered. However, these parts are very difficult to handle. Therefore, they had to be rounded. So we needed a machine for aluminium rounding very quickly." Dirk Schürstedt, Area Sales Manager Metal Processing at Lissmac Maschinenbau GmbH, continues: "Yes, that was really a challenge for us. It took six weeks from the idea to purchase a new plant to delivery. Everything was very focused. Even a coordination problem regarding the necessary conveyor rollers was solved in three hours. That was impressive for everyone involved." And with a view to aluminium machining, a third identical SMB-L 1500 for aluminium machining was also purchased in September 2022. "We have to consider explosion protection when machining aluminium. Extraction was important for the dusts produced. The purchase of a separate extraction system and the resulting conversion of an existing system seemed too costly to us. And so we decided to purchase another machine, to house it in a separate room and thus to take into account all safety aspects as well as to ensure efficient process flows," Andre Wiechmann explains the decision. All three SMB-L units have essentially the same equipment and the same user interface. An additional loop adjustment module was an important feature for Wiechmann when equipping the systems. If the sanding pattern changes due to the running time, the machine automatically adjusts itself. This way, the quality can be reliably set once. This also means that customers can order the sanding quality or the sanding pattern individually. The Right All-Round Package Investing in new technology has paid off for Wiechmann: The grinding processes run much more efficiently and larger parts can be machined. With rounded parts, the paint also holds better, foils on the sheet metal do not have to be removed and engravings are easier to see. Another very important point: The new machines require significantly less electricity. Many of Wiechmann's customers appreciate the machine edge rounding and gladly accept the service. And the new plant technology has opened up yet another business field. "We have customers who produce sheet metal parts themselves and bring them to us for edge rounding," says Wiechmann. And one point is particularly important for the managing director of the Ammerland-based company: working at eye level. "There are no complicated and lengthy processes when working with Lissmac. We don't have to pull a ticket when we need a quick answer to our question in everyday business. We can always rely on the good service and the good mechanical engineering. One thing is certain: We are simply taken seriously as a customer."

Asphalt Paving In A Sensitive Environment
LISSMAC UNICUT 600 cuts through 50 cm thick asphalt and concrete The ground must not shake. This was the premise of the contract awarded by the Friedrich W. Petersen company from Seedorf, which involved the vibration-free removal of a 50 cm thick road surface. Measuring devices in the adjacent houses checked strict compliance with the specification. Cruel methods such as hammering or milling with coarse tools were ruled out. The UNICUT 600, LISSMAC's flagship floor saw, whose diamond saw blade cuts asphalt and concrete surfaces to a depth of up to 63 cm, provided the elegant and efficient solution. The delicate task took the experts for diamond drilling and sawing technology from the company Friedrich W. Petersen into a narrow residential street. The machines had to come within arm's length of the house fronts in order to remove the massive soil structure in the Aubrücke area in Wilster. Years ago, the marshy subsoil had been filled with concrete during a road renovation to secure the floodplain crossing. "As part of a new house supply, the 50 cm thick layer of concrete and asphalt had to be removed. It was imperative that the work be carried out without vibration. This was documented with measuring devices on the surrounding houses for evidence," reports managing director Willi Petersen, whose company specialises in asphalt and concrete sawing. He was commissioned by the construction company Gerd Dallmeier from Bekmünde to cut the asphalt-concrete mix, once designed for maximum stability, into small pieces that could be gently lifted and transported away with a mini-excavator. The chessboard-like cut lines, which crossed the resistant floor structure of the Aubrücke bridge to a depth of 50 cm, added up to around 300 running metres. A demanding task for man and machine, which Petersen and his specialists completed quickly and at the same time as gently as possible with know-how and the right equipment. "Such construction measures are naturally a burden for the residents. Keeping this as low and short as possible was a major concern for us. The measurement data from the vibration sensors also confirm that we have achieved this goal," says Petersen. A total of 50 cross-sections were also created, which were drilled off at the sides, in order to render vibration-intensive chiselling out of the cut surface superfluous. The main load of the cutting work was shouldered by the LISSMAC floor saw UNICUT 600, which is designed for the toughest applications. Travel drive and saw blade speed are electro-hydraulically adjustable. The hydraulically controlled drive proves to be extremely robust even in the toughest continuous operation, can be operated without restriction under full load and works without any appreciable wear. A 100 kW/136 hp Perkins diesel engine provides the power, accelerating up to 1,500 mm diamond saw blades to the set speed and powerfully dragging them across. A highlight from the operator's point of view is the LISSMAC-typical, first-class ergonomics of the machine, which enables low-fatigue floor cutting over many hours. The control is millimetre-precise and effortlessly simple via joystick. The userfriendly design allows multiple seating positions and provides the best overview in both push and drag cutting mode. "The UNICUT 600 makes our back-breaking job much easier. It is fast, precise, reliable and you have a firm grip on the over two-tonne powerhouse with just one finger on the joystick. Every morning, my employees like to get back on the machine. That is good for motivation and it is reflected in our first-class work," says Petersen. Get more information about the product here.
