USER REPORT Circular saw

USER REPORT Circular saw blades carve out a path for India’s economic boom For years, India‘s economy has been growing at a rapid pace. In 2014, the “Make in India” economic initiative was developed specifically for this purpose. One of the key manufacturers taking part in the initiative is Basco Tool Industries from Faridabad, to the south of New Delhi. The company manufactures carbide-tipped circular saw blades and has relied on sharpening technology from VOLLMER for more than 15 years. The Biberach-based specialist in grinding and erosion machines has previously supplied seven machines, including sharpening machines from the CP and CHP model series. common tooth geometries in just one cycle ‐ even when sawing with an axial angle and group toothing. The CP 200 machine is equipped with multiprocessor technology and integrated software programs. So, whether it’s tooth faces or tooth tops, the grinding speed can be freely selected and there’s no need to set tooth pitch or blade thickness. In addition to the sharpening machines, the service technicians at Basco Tool Industries have also received training at VOLLMER’s site in Biberach. Customers from the wood and metal industries ”We are currently manufacturing around 3000 carbide-tipped circular saw blades a month for companies in the wood and metal industry,” says Vikas Tiwari, CEO of Basco Tool Industries. ”Our vision is to not only increase the quality of products and services, but also achieve further growth. Specifically we want to produce at least 10,000 saw blades per month within a few years.” More than 25 circular saw variants Basco Tool Industries’ ambitious goals reflect how the Indian economy looks. For two decades, the Gross Domestic Product (GDP) has grown by more than seven per cent a year. Five years ago, the “Make in India” initiative was established in the country. The goal is to support Indian manufacturers to produce goods in their own nation. Employing around 20 people, Basco Tool Industries develops over 25 variants of carbidetipped circular saw blades for Indian manufacturers, which they then use to process plywood, solid wood, wood composites, plastics and aluminium. Good links between Germany and India Economic life is booming in the neighbourhood around Basco Tool Industries with small workshops, medium-sized factories and large manufacturing companies, all witnessing prolonged growth. Many global companies have regional subsidiaries in Faridabad, including German companies such as the agricultural machinery manufacturer Claas and technology firm Voith. German workmanship also plays a key role at Basco Tool Industries, since the company relies on machines from the Swabian sharpening specialist VOLLMER to sharpen its carbide-tipped circular saw blades. “The connections between Faridabad and Germany have been successful and strong for decades. For that reason, it was clear to us from the start that we, too, could rely on German quality for our machines,” says Vikas Tiwari. “Our first VOLLMER sharpening machine arrived from Biberach back in 2003. Now there are seven machines that we use to manufacture circular saws and tools around the clock.” Growth with VOLLMER sharpening technology VOLLMER has sent equipment that includes a CHP 840 and two CP 200 sharpening machines on the 6000-kilometre journey to Faridabad. With the CHP 840, carbide-tipped circular saws can be sharpened in a single set-up. Its four CNCcontrolled axes allow complete machining of all The customers of Basco Tool Industries are primarily based in the north and east of India. Apart from circular saws and tools, the company also offers a range of services including tool re-sharpening, tool repairs and technical consultation. The customers from the wood and metal industries are supported with training, to help them design efficient and profitable production processes for furniture, windows and doors with technologies from Basco Tool Industries. The aim is to establish additional regional distribution and service centres and ultimately become the leading manufacturer of carbide-tipped circular saws in India. 32 No. 1 • February 2020

USER REPORT Automated veneer handling - sheet by sheet With the help of Piab’s Kenos KVG area gripper, Heinrich Kuper GmbH carries out veneer sorting systems. The biggest challenge was to pick up split and perforated sheets one by one with a vacuum Smart solutions for the automated worldTM gripping system. Piab’s innovative and fine tuneable vacuum technology makes such sensitive handling possible. The plant from above. The veneer sheets in the double compartments are handled with vacuum with the Kenos ® KVG gripper from Piab. In the furniture and flooring industry, more and more veneers are being used, both for cost and weight reasons. Real wood veneers, cut from a tree trunk, continue to be used, especially for high-quality products. The Kuper company builds appropriate systems to sort and assemble the veneers into the desired stacks or to deliver them directly to production. Raw, cut to size, or glued veneers are placed on a distribution table with ten double compartments. An employee in the production department places the veneers of the delivered bundles of sheets, package by package, on one side of the double compartment. When this is full, Piab’s Kenos KVG gripper starts lifting the sheets one by one from the respective stack. When the sheet is secured by vacuum, it is transferred to the pickup unit of a second gripper, which mechanically clamps the sheet and pulls it into the system for sorting or loading. In the meantime, the employee can fill the other compartment, so that the individual veneer sheets can be automatically removed without interruption. Mr. Manuel Duebeler, one of the system designers at Kuper, explains: “The big challenge for us was to find a gripper that was able to pick up only one sheet at a time, regardless of whether it is intact or split or has holes in it. Our first attempts failed, which is why it helped us enormously when one of our customers referred us to Piab because he had good experiences with veneer handling with their Kenos grippers.“ ”The Kenos ® KVG gripper from Piab that was chosen offers a high degree of flexibility and in particular allows the handling of products of different compactness. With the help of flow valves and a flow limitation, the integrated vacuum generation with Piab’s innovative multi-stage COAX ® technology can be precisely adapted to the vacuum requirements. In this way, it was possible to exactly match the level of vacuum generation to the veneer sheets and to balance the performance needed for handling air-permeable sheets with the requirement of picking up just one sheet at a time,” explains Hasan Simsek, responsible sales engineer at Piab, the reasons for the product selection. In addition, the gripper was designed in such a way that there is an intermediate blowing over the entire length of the sheet when it is picked up, so that the veneer sheet is briefly in the air. This process also ensures that only one sheet is lifted per pick. To ensure that Piab’s gripper met expectations, several tests were carried out in advance, first at Piab, then at a test facility at Kuper. “The Kenos ® KVG gripper from Piab convinced us on the one hand because it was the only one that was able to reliably and continuously pick up The veneer sheet is taken over by the pick-up unit of the second gripper. the sheets individually. With a working width of 330 mm and a total width of 350 mm, the gripper can pick up all veneers with a width of 230 mm to 330 mm. The gripper is positioned so that it only handles veneers from one compartment. When a compartment is empty, the entire magazine moves over to the other side and the gripper removes the veneers from the compartment that has been filled in the meantime, ”continues Dübeler and adds,” the cooperation with Piab was also excellent. The gripper was adapted exactly to our needs, which also included the dimensioning of the length of 350 mm. ” Piab’s Kenos vacuum grippers are also characterized by low downtimes during maintenance, since the technical foam that forms the surface can be replaced in a few minutes. With the online configurator, customers can quickly define a possible solution. No. 1 • February 2020 33
