Vollmer debuts QXD 250 PDC tool eroding machine at MACH 2014

And alongside the QXD250 for processing PCD-tipped cutting tools, Vollmer will be promoting its CP200 machine for the automated processing of circular saw blades. The new QXD250 can produce PCD tipped (polycrystalline diamond) tools up to 30% faster than has been possible up to now, courtesy of its new Vpulse EDM generator technology. With targeted eroding impulses, the Vpulse EDM can improve the surface finish by a factor of two or more. The QXD250 gives greater flexibility and opens up a wide range of new possibilities for PCD tool manufacturers when processing PCD cutting tools. The surface finish quality and processing speed of the QXD250 is far beyond that of competitor machine tools, says the company. Depending on demands, the Vpulse EDM can either increase the speed of tool production or better the surface fineness. The Vpulse EDM achieves these advances when processing PCD surfaces by using individually cycled eroding impulses. This corresponds to two-fold improvement and more in comparison to the eroding technology that is currently available from alternate vendors. Apart from the newly developed eroding generator Vpulse EDM, the Vollmer universal machine also offers a simultaneous interpolation in six CNC controlled axes. And as a result of the increased tool track distance and swivel range, PCD tools with diameters of 320 mm and lengths of 250 mm can be processed. In one single clamping fixture, the QXD250 measures, grinds, erodes and polishes diamond tools in one combined process. Vollmer automation technology allows unmanned 24-hour production, during which the loading and emptying of the workpiece reservoir can take place simultaneously by automatic operation. The integrated toolchanger, for up to six eroding, grinding or polishing discs, makes the processing of different work piece variants possible. For machining circular saw blades, Vollmer will re-introduce its market-leading CP200. This has proven itself time and again in the market since its launch with its four controlled CNC-axes that allow optimal movement coordination and top precision for grinding carbide-tipped circular saw blades. Capable of cutting costs and boosting long-term productivity with its automation levels, the CP200 can machine all common tooth geometries in one cycle, with the new Vollmer user interface guaranteeing simple and convenient operation on the colour LCD display. The CP 200 delivers compactness, precision and performance. MACH 2014 - Birmingham NEC, 7-11 April
