An Austrian family-owned develops, manufactures and sells solutions for managing torsional vibrations in large diesel and gas engines. Its product range includes torsionally and resiliently flexible couplings and torsional vibration dampers made of steel and composite fibre materials. They are used in ship propulsion systems, power plant generators, bulldozers and rail locomotives, to give a few examples. One of the first production areas is the sawing unit. Round and flat steel stock, mostly tempered steel supplied as bar material, is cut to precise lengths. The high-grade materials are very hard to cut. Since December 2014, a KASTOtec FC 4 automatic band sawing machine made by the sawing and storage technology specialist KASTO has been in operation here. The saws in use before that time were unable to meet the increasing demands on cutting performance. The company didn’t take long to discover KASTO Maschinenbau GmbH & Co. KG. With the KASTOtec FC 4, KASTO offers a solution which is perfect for jobs of this kind. With its cutting range of 430 millimetres and smallest cutting dimension of 10 x 10 millimetres, it can efficiently handle materials of different diameters. Moreover, the added feature KASTO Performance Cutting (KPC) makes the saw suitable for using carbide saw blades. “KPC includes a number of measures to improve the guidance of the saw blade, to prevent vibration and to optimise damping of the sawing tool”, explains Sönke Krebber, head of strategic predevelopment at KASTO. “For example, vibration is effectively damped by a pair of spring-loaded guides on the return blade, ensuring quieter operation”.
