Abstract: The effects of the different graphite type, particle size and content on the performance of metal diamond abrasives were studied using the method of orthogonal experiment, measuring the abrasive ratio and mechanical property. The experimental results show that the abrasive ratio of metal diamond abrasives reaches 206 . 62 , the mechanical property is fine and the sharpness is high when the adding mass fraction of flaky graphite is 3wt%,and particle size of flaky graphite is 80 mesh. So the comprehensive properties of metal diamond abrasives are high, which would make certain significance for practical application.
