Experimental study on a new combination processing technology of polycrystalline diamond

摘要

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.
