HIGH PRECISION MACHINING OF PCD TOOLS The VOLLMER QM eco select was developed for the machining of tools, in particular those with PCD cutting edges, with the utmost precision and best possible surface quality. It meets the highest demands for innovative geometries, configurations of cutting edges and accuracy that diamond tools require. An extremely high structural rigidity has been achieved thanks to the particularly stable, flexible machine design, which includes polymer concrete. Measuring and eroding are achieved with the VOLLMER QM eco select with just one clamping operation. Five simultaneously controlled CNC axes and the generator we have developed ensure top performance and optimum results.
