Abstract

Polycrystalline diamond compacts (PCD) has high hardness, good anti abrasion property. The precision processing technology of PCD is key technology in applications. This article introduces a new combination machining method of polycrystalline diamond (PCD). This machining method combines diffusion machining with free abrasive milling. In the processing polycrystalline diamonds in PCD were removed by the diffusing; binders in PCD were removed by grinding. The two main factors in the processing were described. The results of the experiment indicate that grinding speed, abrasives particle - size are factors of the significant impact.
