Research on development of the new PCD tool made of an electrically-conductive diamond and its processing method

由导电金刚石颗粒组成的新型PCD(EC-PCD)与现有的商用PCD相比，在电火花加工、电火花加工、W-EDM和复合电火花磨削等方面具有良好的加工特性。由EC-PCD制成的V形砂轮的电火花成形也是可能的。在这种情况下，EC-PCD车轮的边缘变得非常锋利。此外，在金属结合剂金刚石砂轮的复合电火花磨削中，可以实现PCD的高效率、高精度加工。获得了EC-PCD材料用作刀具、砂轮、模具工具、电极和精密零件的准则。

A new PCD(EC-PCD) made up of electrically conductive diamond particles has good processing characteristics outstanding in EDM, EDG, W-EDM and complex electro-discharge grinding method, compared with the existing commercially available PCD. Electro-discharge forming for a V shape grinding wheel made of EC-PCD is also possible. In this case, the edge of the EC-PCD wheel became very sharp. Furthermore, in the complex electro-discharge grinding by using a metal bonded diamond wheel, it is found that the high-efficient and high-precision processing of PCD would be realizable. The guideline for utilizing an EC-PCD material as a cutter, a grinding wheel, a mold tool, an electrode, and precision parts was acquired.
