Electrically conductive PCD(EC-PCD), which was made up of the electrically conductive diamond particles, was applied to an electrode material for precise EDM of cemented carbide die. The machinability of EC-PCD by EDM was investigated in comparison with standard PCD. It was found that EC-PCD was machined at better surface finish compared that of standard PCD because the diamond particles in EC-PCD were flattened by electro discharge. In EDM of cemented carbide die, the EC-PCD electrode shows the extremely low wear compared with the existing Cu-W electrode. Furthermore, the increase of material removal rate and improvement of surface property compared with the standard electrode can be realized.

将导电金刚石颗粒制成的导电PCD（EC-PCD）应用于硬质合金模具精密电火花加工的电极材料。研究了电火花加工EC-PCD的可加工性，并与标准PCD进行了比较。结果表明，由于电火花加工使金刚石颗粒变平，EC-PCD的表面光洁度优于标准PCD。在硬质合金模具的电火花加工中，与现有的Cu-W电极相比，EC-PCD电极显示出极低的磨损。与标准电极相比，可实现材料去除率的提高和表面性能的改善。
