The Vollmer eroding machine QXD 250 makes it possible for tool manufacturers to process more than 30 percent more PCD cutters in the same amount of time as has been the case up to now. This milestone in production is made possible by the generator technology Vpulse EDM, which sets the eroding beat at the heart of the QXD 250. Depending on the demands, the Vpulse EDM can increase the speed of the tool production or increase 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 available until now.

The QXD 250 gives greater flexibility and opens up a wide range of new possibilities for PCD tool manufacturers when processing PCD cutters, allowing manufacturers to react in a targeted way to the demands of their customers and markets. The Vollmer universal machine also offers a simultaneous track interpolation in six CNC controlled axes. As a result of the increased tool track distance and swivel range, PCD tools with diameters of 320mm and lengths of 250mm can be precisely processed. In one single clamping fixture, the QXD 250 measures, grinds, erodes and polishes diamond tools in only one combined process. The Vollmer automation technology allows 24-hour production without the need for an operator to be present, during which the loading and emptying of the workpiece reservoir can take place simultaneously by automatic operation. The integrated tool changer for up to six eroding, grinding or polishing discs makes the processing of different work piece variants possible.
