Vollmer, the global specialist for grinding and eroding machines, will present its new eroding machine QXD 250 for the first time at the International Trade Fair for Forestry and the Wood Industries Ligna in Hanover. Thanks to the new generator technology Vpulse EDM, QXD 250 PCD tipped (polycrystalline diamond) tools can be produced up to 30 percent faster than has been possible up to now. With targeted eroding impulses, the Vpulse EDM can increase the surface fineness by a factor of two or more. This gives the QXD 250 more flexibility in terms of tool production, which allows Vollmer to offer tailored-made solutions to the different demands of customers and the market.

“PCD tipped tools have a significantly higher service life than any comparable hard metal tools when it comes to working on highly abrasive materials,” says Dr. Stefan Brand, Managing Director of the Vollmer Group. “With our QXD 250, we are contributing to making the production of made-to-measure diamond tools cheaper when produced in large quantities while still maintaining the highest quality standards.”

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 new 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 which have been available up to now.
