This article introduces the compound machining method of polycrystalline diamond(pcd), according to themachining characteristics of different components in polycrystalline organization, this machining method combines diffusionmachining with grinding. Diffusion processing was used for diamond component in the polycrystalline; at the same time, thebinder which hinders the diamond diffusion processing was grinded. After the composite processing, PCD organization wasstudied, which uses SEM and other analysis methods. Research shows that: polycrystalline diamond component wasremoved by the diffuse processing; binder component was removed by grinding processing. The investigation shows that thediffusion -grinding process has many more advantages than traditional method in machining polycrystalline diamond (PCD).
