Abstract

Abstract

The development and technical characteristics of diamond tools are introduced. A grinding method for controlling the surface roughness of the rake face of natural diamond tools is designed. The results show that for the diamond (100) surface, the surface roughness is good along "hard" direction with more grinding heat while poor in the "soft" direction with less grinding heat. By optimizing the grinding angle, the surface roughness of the rake face of the diamond tool can reach a goodR_avalue of 0.3 nm. Good application effects are presented in the ultra-precision cutting.
