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.
Setting the Course for the Future with a Machine Package
Robert Plersch Edelstahltechnik GmbH has a long history: The company was founded in 1819 as a small building fitter's shop, grew and in the meantime also produced its own products with cookers and ovens for private households and the catering trade. Originally based in Ottobeuren, the company moved to its current location in 1985. In the 1980s, the portfolio was switched to sheet metal working under Robert Plersch. "Since then, we have grown steadily. More and more new technology and automation was added. That was my father's philosophy," says managing director Georg Plersch, who is now the sixth generation to run the company. After three years of working together and intensive training, the company was handed over from father to son at the end of 2019/beginning of 2020. Deburring should be automated Right at the start of his new job, the industrial engineer with a degree in mechanical engineering had a complex task to master. Investments should be made. All departments should work at a similarly high technical level. Looking at the individual production areas in the company, things looked very different before the current investment. In the field of sheet metal processing, the latest plants from Trumpf was available. Production took place in three shifts on five lines. This resulted in a very large throughput of sheet metal parts, steel and stainless steel parts and aluminum parts. Then came the next work step with deburring. And a lot of manual work was still done in this area. "It didn't add up. In one area we are fully automated in a three-shift system and then manual work follows. It wasn't just the number of employees in the deburring area that we were lacking. It is also simply a question of staff motivation. In addition, customer requirements have become more and more demanding in recent years," says Georg Plersch, looking back. The plant technology therefore had to be adapted to the changed production requirements. "On the one hand, we wanted to process the high volume of sheet metal parts as efficiently as possible and implement the increased requirements for deburring, such as deburring on both sides. On the other hand, the employees should be relieved, because hand deburring is quite strenuous," Plersch describes the key data. So when looking for new plant technology, the focus was on throughput times, quality and automation. And so the plant concepts of various manufacturers were looked at and tested with a view to the company's own production requirements. It was obvious that the company Lissmac was also contacted. On the one hand, there was already a Lissmac system for deburring and rounding steel sheets with an existing SBM-L1500. They were satisfied with the technology. On the other hand, Lissmac is also a Plersch customer, because the Bad Wurzach-based machine builder obtains sheet metal components for its own machine production from Plersch. So they have known each other for many years, work together as partners and appreciate each other's competences. Higher quality in less time Initial discussions on the planned investment took place in 2017. At the end of 2018, the experts from Lissmac were then on site in Hawangen at Plersch to look at the production processes and propose a plant concept. The processes and also individual manufacturing steps of the parts and assemblies were thoroughly scrutinised. "Clear was: The material flow had to be optimised and in this context short "lay times" of the parts and short delivery times for the customers had to be realised. We also had to react to the topic of "high quality in less time", which is becoming more and more important," says the managing director, summarising a few basic requirements for the new plant technology. On the Lissmac side, Alexander Bochtler was in charge of the project from the beginning. Looking back, he says: "There were so many different requirements that had to be covered: many small parts, many large parts or also different requirements for the surface. This would not have been feasible with one machine. So the area sales manager for metal processing at Lissmac Maschinenbau GmbH presented several systems from the Lissmac portfolio that are particularly suitable for individual applications. A detailed deburring concept was created for this purpose. This concept showed exactly which Lissmac system would be suitable for which parts and part requirements from the Plersch portfolio. Once the deburring concept was available, the Plersch decision-makers travelled to the Lissmac demonstration centre to put the proposed system technology through its paces. "Of course, we had a few surprises in the boot in addition to quite normal parts that are manufactured by us. In other words, parts that are quite a challenge to machine," Georg Plersch smiles today. These were parts that were very time-consuming and labour-intensive to process. Here, the new plant technology should achieve a significant improvement with high quality. "The deburring bottleneck should definitely be eliminated in our company," says Plersch.. And he goes on to say: "In our business, maximum flexibility in parts processing is required. That's what customers expect from us. We also pass this requirement on to the machine manufacturer." Detailed deburring concept was convincing In the end, Plersch decided on a machine package in March 2019, consisting of a total of three systems. Specifically, the SBM - L 2000 G1S2 grinding and deburring machine was purchased purely for stainless steel and aluminium operations. Plersch now uses this system to process formats from 150 mm x 50 mm to 1700 mm x 2500 mm. This unit deburrs the inner and outer contours on both sides. The manual preparation of these components that was previously necessary is completely eliminated with the new system and the parts are finished in one pass. The newly acquired SBM - XS 300 G1E1 is now used for the double-sided machining of vacuum-capable small parts, especially for components with batch sizes of 5000 pieces per month, as well as for other small parts in order to bypass vibratory grinding and thus significantly minimise the throughput time of these parts. With the acquisition of the third Lissmac machine, a single-sided SMD 545 RRRR with a working width of 1350 mm, it is now possible to achieve the highest quality surface grinding. This unit was specially designed for stainless steel operations. Appropriate use was also proposed for existing machines that were still in use at that time. And the new equipment could be installed as early as the end of 2019. Greater flexibility and more capacity options Plersch's main focus is to react flexibly to the customers' requirements. The company is broadly positioned in terms of both part geometry and materials. Steel, stainless steel and aluminum are processed and work is carried out for all sectors, from vehicle and machine construction to medical technology and energy technology. So the mini component for the electrical industry is machined in exactly the same way as the six-metres assembly - from one piece to several tens of thousands. With the new system technology from Lissmac, greater flexibility in order processing is now possible. For example, process times could be significantly reduced for laser punched parts that subsequently have to be deburred. The edge rounding of parts that are subsequently powder-coated and must therefore be burr-free to ensure optimum paint adhesion is now also much easier and, above all, process-reliable. Logistically, too, there was a reaction to the new technology: The processing of steel and stainless steel must be spatially separated so that there is no contamination. The internal logistics were adapted accordingly. Likewise for the processes that take place on the SMD 545, i.e. for the grinding of surfaces. The year 2019 has been a busy year for Plersch. The investment in the Lissmac plant package was extensive. In addition, a new production hall has created additional space capacity for existing production. And last but not least, the handover of the management from Robert Plersch to Georg Plersch marked another milestone in the company's history. "We wanted to set an example and show that we are setting the course for the future together," says Georg Plersch. Adherence to deadlines can be reliably ensured After the investment, it is now important for Plersch that support is ensured, that a contact person is quickly on hand when needed and that spare parts are also quickly available. It's about the overall concept, not just the pure investment. This is also important for Alexander Bochtler: "It was a great cooperation, characterised by exchange and dialogue. We were able to design efficient processes. But we don't just sell machines, we sell solutions - with time and machine life in mind." At Plersch in Hawangen, sustainable and attractive workplaces have also been created due to the investments in new plant technology and the ergonomics have been designed as optimally as possible for the employees. And what are Georg Plersch's wishes for the coming years? "Of course, healthy growth for our company and the opportunity to do quality work. But also more peace from the outside. When it comes to difficult issues like Corona, the energy crisis or the shortage of skilled workers, I would basically like to see more support for SMEs from our politicians," he says.

Excellence in floor preparation
LISSMAC's new series of floor grinding machines and floor milling machines Innovation is a trademark of LISSMAC. With the series of floor grinding and floor milling machines presented for the first time at Bauma 2022, the company is adding a new product field to its range. "As a leading manufacturer of floor saws, stone saws, wall saws, wire saws and core drills, we know how to build machines that reliably deliver top performance under the toughest conditions. Our new grinding and milling machines cover exactly the needs of professionals in floor preparation" says managing director Daniel Keller. Six grinding machines and three milling machines make up LISSMAC's powerful new product family, designed for a wide range of tillage tasks from quick-fix repairs to demanding large-scale operations. At the start of production, a comprehensive selection of tools is already available that are precisely matched to the machines and their intended use and ensure maximum efficiency and reliability. The all-in-one range is rounded off by the VACUUM-DRY industrial hoovers in two performance levels. Equipped with HEPA filters + PTFE, they meet dust class H and achieve air flows of 340 m³/h and 510 m³/h respectively. Smooth and non-slip - the new BSM floor grinding machinesWith six models ranging from 2.2 kW to 11 kW of high-torque electric power and working widths of 270 mm to 650 mm, the floor grinding machines from LISSMAC handle the majority of tasks that arise in professional floor preparation. The LISSMAC diamond tools, which are carefully matched to the machines in different grit sizes and segment hardnesses, produce first-class surfaces on floors such as concrete, screed or terrazzo and score points with long service lives. The stick roller system creates a roughened sansurface similar to shot peening. High-quality visible surfaces can be created or renovated in a short time with the diamond polishing pads. The LISSMAC PCD tools effectively remove adhesives, paints or coatings from surfaces.The handy floor sanding machine BSM 270 E with 2.2 kW 230 V motor and 270 mm working width inspires anew every day as a nimble allrounder for the high-abrasive subfloor preparation of floors. Super light, super powerful and super fast is the BSM 310 E with a particularly durable brushless 230 V motor, 310 mm working width and 38 kg operating weight. The BSM 340 E with its speed-regulated, 5.5 kW 400 V motor and 340 mm working width is recommended for coarse work with high removal rates. An economical solution for all cases, equally efficient for dry applications, is the BSM 450 E 3-disc sanding machine with an impressive 450 mm working width and 230 V motor with 2.2 kW. The BSM 525 E with its speed-regulated, 7.5 kW 400 V motor, trimmed for maximum performance, really puts the pressure on when it comes to demanding dry and wet sanding. The working width of the 3-disc sanding machine is 525 mm. Flagship performance on a 650 mm working width is delivered by the BSM 650 E with 11 kW engine, which powerfully pulls through the adjustable speed even on rough jobs. The weight of the heavy floor grinder is optimally balanced for high stock removal and energy-saving operation during long operations. All LISSMAC floor sanding machines are characterised by the fact that they are also ideally suited for work close to walls. Good from the ground up - the new BFM floor milling machinesWith cracks, blisters, chipping and increased susceptibility to weathering, the costly consequences of inadequate substrate preparation inevitably come to light sooner or later. The new LISSMAC floor milling machines produce a high adhesive tensile strength on concrete and screed surfaces and thus prepare the load-bearing basis for further floor construction. The powerful and robust machines compensate for height differences of up to 8 mm and efficiently remove adhesives, paints as well as foam residues from floors. Three practically graded machine sizes deliver solid performance day after day on 200 mm to 320 mm working widths. The LISSMAC tools, which are precisely tailored to the market requirements, convince with an attractive price-performance ratio, ensure first-class surface quality and guarantee long tool lives.The BFM 200 E proves itself as a compact universal machine, which, for all its manageability, also comes up trumps with performance and durability - the classic LISSMAC virtues. Driven by a 2.2 kW 230 V motor, it achieves milling depths of up to 2 mm with a working width of 200 mm. The BFM 250 E is still compact and easy to use, but is in a whole new performance class. Its 4 kW 400 V motor provides the power and endurance for demanding applications with a maximum milling depth of 5 mm over a working width of 250 mm. Large areas and the most demanding tasks are the métier of the BFM 320 E, the largest floor milling machine from LISSMAC with a working width of 320 mm, which can be converted to a diamond milling machine with 24 diamond blades in a short time. Driven by an 11 kW 400 V motor, it mills up to 8 mm deep on concrete C20/25 in one operation. Equipped with a stepless hydrostatic drive for forward and reverse travel, the ergonomically designed machine protects the operator's strength during continuous operation.

Entgrat- und Richttechnik in einer Anlage vereint
At Euroblech, the two machine manufacturers LISSMAC and KOHLER showed a jointly developed system. It illustrates how the deburring and straightening processes can be optimally coordinated with each other and thus generate high efficiency potential for the overall process. The grinding, deburring and partial straightening of sheet metal parts are processes that usually go hand in hand. It is therefore a good thing if the competences are also combined in the development of the equipment. Against this background, LISSMAC Maschinenbau GmbH and KOHLER Maschinenbau GmbH have jointly developed a deburring-straightening line. The line combination, which was presented at Euroblech, consists of the SBM-L G1S2 1500 grinding and deburring machine from Lissmac and a Peak Performer parts leveler from KOHLER, according to a company release. The SBM-L series machines are basically suitable for double-sided processing of workpieces made of stainless steel, steel, aluminum or non-ferrous metals, it added. They were developed for deburring and edge rounding on both sides in a single operation and can be used for processing sheet metal parts, laser parts and stamped parts. The L series is equipped with three units each on the top and bottom sides. Workpieces can be machined on the top side, the bottom side or both sides as desired, sp the manufacturer. "Double-sided sheet metal processing and edge rounding in just one operation enables time savings of up to 60 percent compared to grinding machines that process on one side. It is also possible to connect automation solutions or integrate it into production lines without any problems. This is exactly what we have realized with our partner KOHLER," says Robert Dimmler, Sales Director Metal Processing at LISSMAC Maschinenbau GmbH. The integrated Peak Performer machine from KOHLER enables precise straightening and thus low-stress and flat sheets as well as part blanks, he adds. The system features a direct drive for the straightening rolls, which ensures greater energy efficiency, less wear and a higher straightenable cross-section, it adds. An advanced cleaning system enables easy cleaning of the straightening rolls and back-up rolls. In addition, the patented electromechanical straightening gap control ensures a reliably constant straightening gap, the likewise patented reversible straightening rolls ensure a longer service life, and extra-wide back-up rolls provide particularly stiff support for the straightening rolls, it adds.

bauma Ausfahrt 2022
Saturday is always the most popular day for visitors during the bauma week. This year, a trip to bauma was organized by our works council on Saturday, October 29, 2022. Together a group of more than 50 colleagues started early in the morning by bus towards Munich. Of course, the LISSMAC booth was also visited to meet the colleagues on site and to marvel at our products. All in all it was a successful trip with many different impressions. Many thanks to the works council for the great organization! We are looking forward to the next bauma in three years.
LISSMAC Service Training Metal Processing
October was a busy month for LISSMAC: Both Euroblech in Hanover and BAUMA in Munich were on the agenda.Since many of our international dealers used this as an opportunity to visit Germany, we offered a service training at our headquarters during this period.The offer was well received and with 10 participants we started on 24.11.2022 in our demonstration center in Bad Wurzach. Part of the one-week training was an update on new products and the process-safe handling of our machines, so that a smooth commissioning/maintenance can be guaranteed by our staff.Due to the wide range of international participants, various experiences could be reported and exchanged. This is not only important for the dealers/service partners themselves, but also for us as a company, because it is only through feedback that we can continue to develop. We are already looking forward to the next training and will announce new dates here.
LISSMAC AT THE EUROBLECH – Grinding and deburring technology for the most diverse requirements
Euroblech è una delle fiere più importanti per il produttore di macchine Lissmac, con particolare attenzione alla lavorazione della lamiera. Quest'anno l'azienda si concentra sulla presentazione della serie SBM e della serie SMD 3. Entrambi i tipi di macchine sono altamente efficienti e possono essere adattati individualmente a un'ampia gamma di requisiti dei clienti. In sostanza, i clienti Lissmac hanno sempre la possibilità di scegliere tra due concetti di macchina per l'elaborazione degli ordini: la lavorazione su due lati in un'unica operazione e la lavorazione su un solo lato - a secco su un lato o a umido sull'altro. La lavorazione a secco su entrambi i lati offre un grande potenziale di efficienza Ad Hannover, Lissmac presenterà tre modelli della serie SBM. "Queste macchine stabiliscono degli standard nella lavorazione della lamiera. Nel processo di lavorazione a secco, tutti i contorni di taglio della lamiera, cioè i contorni esterni e interni, vengono lavorati in modo efficiente su entrambi i lati in un solo processo di lavoro. La lavorazione sincrona su entrambi i lati offre la massima produttività e i migliori risultati di lavorazione", afferma il produttore. Il principio di lavorazione garantisce un'usura uniforme dell'utensile su tutta la larghezza di lavoro. Inoltre, la lavorazione a secco non richiede l'uso di additivi chimici, come nel caso della vibrofinitura. Secondo Lissmac, tutte le macchine di questa serie sono sinonimo di efficienza energetica e di qualità di lavorazione elevata e costante. Inoltre, è possibile cambiare gli utensili in modo semplice e veloce.Il portafoglio macchine Lissmac comprende quattro serie di macchine. A seconda del compito di produzione o dello spessore della lamiera, vengono utilizzate le serie SBM-XS, SBM-M, SBM-L o SBM-XL. Questi modelli di macchine si differenziano per la larghezza di lavoro, il numero e il tipo di aggregati per la lavorazione dei pezzi. Lavorazione completamente automatica di piccoli pezzi Soprattutto nella lavorazione di piccoli pezzi, spesso vengono lavorate grandi quantità. Lissmac presenta la sbavatrice per piccoli pezzi SBM-XS 300 ALU MIX con robot di carico. La macchina garantisce un processo di produzione efficiente e a basso impiego di manodopera attraverso il picking dei cassonetti. Si distingue anche per il design moderno e compatto della macchina, che richiede poco spazio, e per il funzionamento semplice e intuitivo della macchina. La SBM-XS 300 ALU MIX con tavola a vuoto è progettata per la sbavatura e l'arrotondamento dei bordi di acciaio, acciaio inox e alluminio con spessori di lamiera da 1 a 15 mm e, a seconda della geometria, per dimensioni dei pezzi da 45 x 45 x 1 mm fino a un massimo di 200 x 200 x 15 mm. I contorni interni ed esterni sono lavorati allo stesso modo. La stazione di tornitura integrata elimina la necessità di una lunga tornitura e rilavorazione dei pezzi. La stazione di tornitura può essere ripiegata in modo da poter lavorare su un lato anche pezzi con bordi di lunghezza superiore a 200 mm. Per la sbavatura e l'arrotondamento simultaneo dei contorni interni ed esterni dei pezzi punzonati, nonché per i pezzi tagliati al laser o al plasma, saranno esposti i due sistemi a secco SBM-L 1000 G1S2 e SBM-L 1500 G1S2. L'obiettivo di entrambi i sistemi, realizzati con larghezze di passaggio rispettivamente di 1000 mm e 1500 mm, è la rimozione degli schizzi sulla superficie della lastra. Anche in questo caso, la sbavatura dei pezzi, spesso molto pesanti, su entrambi i lati, consente di evitare la costosa tornitura o la doppia lavorazione dei pezzi. Le unità di lavorazione sono regolabili elettricamente singolarmente o possono essere accese e spente. Il principio di lavorazione trasversale garantisce un utilizzo ottimale dell'utensile su tutta la larghezza di lavoro e la struttura modulare e compatta, nel moderno design della macchina, richiede uno spazio ridotto.Molto importante per i dipendenti che lavorano sulla macchina è il miglioramento dell'ambiente di lavoro della macchina grazie alla tecnologia di estrazione e filtraggio. Questo riduce in modo significativo l'inquinamento da polvere, sporco e rumore. In opzione sono disponibili funzioni intelligenti come la compensazione automatica dell'usura degli utensili, la misurazione automatica dello spessore della lamiera, uno scanner di codici a barre e altri strumenti. Lavorazione a secco efficiente su un solo lato per principianti e professionisti La gamma di macchine per la rettifica a secco su un solo lato comprende i modelli base della serie SMD 1, particolarmente economici. La loro gamma di applicazioni spazia dalla sbavatura e dall'arrotondamento completo degli spigoli alla rimozione di scorie pesanti da plasma o da fiamma.A Euroblech, Lissmac presenterà la macchina universale entry-level SMD 123 RE, che può essere utilizzata per la lavorazione di acciaio, acciaio inox e alluminio. È adatto per rimuovere le bave di taglio che si formano durante la punzonatura o il taglio al laser e al plasma. Le due teste del rotore del sistema consentono un arrotondamento uniforme dei bordi su tutti i lati e una finitura non direzionale. La rettifica di superficie è possibile senza richiedere un lungo lavoro di impostazione. I componenti con formatura possono anche essere lavorati. Lo SMD 123 RE richiede poco spazio e può essere utilizzato in modo intuitivo tramite un pannello a sfioramento. Altre caratteristiche sono l'accensione e lo spegnimento separati delle unità di lavorazione, la velocità del nastro abrasivo regolabile in continuo e il cambio rapido e semplice degli utensili. Nel segmento ad alte prestazioni, i versatili modelli della serie SMD 3 convincono per la lavorazione efficiente di pezzi da 50 x 50 mm, indipendentemente dalla geometria del pezzo. La gamma di applicazioni spazia dalla rimozione delle scorie, alla sbavatura e all'arrotondamento uniforme dei bordi fino a un raggio di 2,0 mm, fino alla finitura delle superfici e alla lavorazione di piccoli pezzi. "La disposizione ben studiata degli utensili della serie SMD3 garantisce un risultato di lavorazione uniforme su tutta la larghezza di lavoro. Il massimo contatto dell'utensile con i componenti garantisce un perfetto arrotondamento dei bordi fino a un raggio di 2 mm. Una memoria di programma garantisce l'impostazione automatica della macchina e risultati di lavorazione riproducibili, mentre la tavola fissa con altezza costante assicura un lavoro ergonomico", afferma il costruttore di macchine Lissmac, riassumendo alcuni dei vantaggi. Inoltre, il funzionamento è intuitivo grazie a un pannello a sfioramento ben strutturato e l'impostazione della macchina è rapida grazie al posizionamento automatico degli assi degli utensili. Un sistema di cambio rapido degli utensili riduce al minimo i tempi di messa a punto e l'accessibilità ottimale della macchina facilita la pulizia e la manutenzione. Ad Hannover, i visitatori dello stand Lissmac potranno saperne di più, ad esempio, sull'SMD 345 REER (S-Edition). La macchina può essere utilizzata per un'ampia gamma di applicazioni, dall'arrotondamento dei bordi R2 alla finitura. Diverse spazzole rotonde consentono inoltre di creare modelli di molatura non direzionali e di arrotondare fortemente i bordi. Secondo LISSMAC, la macchina è anche predestinata per la lavorazione di lamiere con rivestimento, sventagliamento, goffratura o alimentazione passante, per la lavorazione di materiali diversi come acciaio, acciaio inox e alluminio e per la lavorazione simultanea di materiali diversi.alluminio, nonché la lavorazione simultanea di diversi spessori di materiale.L'SMD 335 DRE (P-Edition), che verrà presentato, è adatto alla lavorazione di lamiere spesse. Si distingue per la rettifica a freddo grazie al basso apporto di calore ai pezzi. La rimozione meccanica delle scorie elimina anche la necessità di costose lavorazioni meccaniche, con conseguente riduzione dei costi degli utensili per l'utente. Come per tutte le macchine della serie SMD 3, LISSMAC offre anche diverse funzioni opzionali per soddisfare le esigenze individuali dei clienti. In collaborazione con gli specialisti della tecnologia di raddrizzamento di Kohler Maschinenbau GmbH, Lissmac presenterà allo stand della fiera anche una linea di lavorazione per lo sgrappolamento e la raddrizzatura dei pezzi in un'unica operazione. L'interconnessione dei due processi assicura un processo produttivo e un flusso di materiali efficienti, riducendo così in modo significativo lo sforzo necessario per la movimentazione dei materiali e la logistica. "La massima qualità di lavorazione dei pezzi è il prerequisito ottimale per l'ulteriore lavorazione e trasformazione dei componenti", afferma Lissmac. Indipendentemente dal compito che le aziende desiderano risolvere, il team di esperti Lissmac è pronto a fornire consulenze individuali e scambi professionali. Lissmac sarà presente a Euroblech nel padiglione 14 allo stand K06. Testo: Annedore Bose-Munde
40 anni di seghe a nastro per muratura – una storia di successo realizzata da LISSMAC
"La sega a nastro per muratura MBS è uno dei prodotti di maggior successo nella storia di LISSMAC. Questa innovazione ha segnato l'inizio dell'ascesa dell'azienda, che da piccola impresa familiare è diventata oggi, nel 1982, un'azienda a vocazione internazionale con circa 400 dipendenti e un'ampia gamma di prodotti", afferma l'amministratore delegato Daniel Keller. Prima di allora, i mattoni e i blocchi di cemento cellulare venivano faticosamente segati a mano nei cantieri e faticosamente raddrizzati con una pialla. 40 anni dopo, la serie LISSMAC MBS (MauersteinBandSä-ge) mantiene la sua posizione di leader sul mercato. In collaborazione con gli utenti, i suoi punti di forza sono stati ulteriormente sviluppati e adattati alle crescenti esigenze. La sega a nastro per muratura LISSMAC era appena arrivata sul mercato quando è diventata un bestseller. "Era 'solo' una sega, ma ha rivoluzionato una fase di lavoro che viene svolta migliaia di volte al giorno nei cantieri di tutto il mondo", spiega Keller. Creare di più con meno sforzo e ottenere allo stesso tempo una qualità migliore: LISSMAC non ha dovuto spiegare questi vantaggi tangibili a nessun appaltatore. La domanda fu enorme e le macchine andarono a ruba. "Nei primi anni abbiamo raggiunto una quota di mercato incredibilmente alta nel settore del calcestruzzo cellulare. Spesso le seghe venivano noleggiate ai clienti dai produttori di AAC quando acquistavano i mattoni", i dipendenti LISSMAC in pensione ricordano ancora con piacere i primi anni di successo. La sega a nastro per muratura è stata progettata come strumento preciso e affidabile per un uso professionale intenso, ma è comunque così semplice e pratica da utilizzare che anche i dilettanti che lavorano a casa possono lavorare immediatamente e in sicurezza con la sega a nastro per muratura. Migliorare le cose belle è uno dei punti di forza tradizionali del LISSMAC, così come l'innovazione. Già nel 1984, due anni dopo il suo lancio sul mercato, si è avviata la prima fase evolutiva del bestseller: l'MBS 502 aveva già il nome del prodotto che è tuttora valido e brillava in verde anziché in arancione, il colore aziendale di LISSMAC all'epoca, fino a quando l'azienda ha adottato un nuovo corporate design in blu nel 2009. MBS 502 significava sega a nastro per muratura con diametro della girante di 500 mm nella seconda generazione. Oggi LISSMAC offre soluzioni perfette per ogni esigenza dei clienti con tre versioni di MBS, i cui nomi sono ancora in uso. MBS 510 sta per 510 mm di altezza di taglio. A questi si aggiungono l'MBS 650 e l'ammiraglia MBS 760, con cui è possibile elaborare facilmente anche blocchi di grandi dimensioni. La macchina è dotata di un robusto piano a rulli che può essere posizionato con estrema precisione anche in presenza di carichi pesanti e che rende molto più semplice e veloce la movimentazione di pietre di grande formato."Prestazioni con valore aggiunto è sempre stato il nostro claim. Il vantaggio decisivo in termini di prestazioni contraddistingue tutte le macchine LISSMAC: l'MBS è stato il punto di partenza", afferma Keller. Le seghe a nastro per muratura MBS si sono affermate per quattro decenni con un'affidabilità che richiede poca manutenzione, anni di precisione e dettagli unici copiati dal lavoro quotidiano nei cantieri di tutto il mondo. Ad esempio, LISSMAC ha consegnato diversi MBS 510 e MBS 650 a Dubai, dove Sobha Construction LLC doveva tagliare con precisione millimetrica oltre 200.000 blocchi di cemento cellulare per la costruzione di un resort di lusso. "In cantiere, sono proprio i dettagli apparentemente minori delle macchine a fare la differenza decisiva tra il piacere e la frustrazione del lavoro. LISS-MAC è sinonimo di perfezione e vantaggi pratici: gli utenti lo apprezzano. Anche qui a Dubai", afferma Johnson Pereira, responsabile vendite della sede LISSMAC negli Emirati Arabi Uniti, fornendo un altro episodio della storia di successo quarantennale delle seghe a nastro per muratura LISSMAC.
