采用正交实验法,通过测定金属结合剂金刚石磨具的磨耗比,结合考虑磨具的力学性能,综合地研究了不同石墨种类、粒度和含量对金属结合剂金刚石磨具性能的影响。实验结果表明：当添加质量分数为3wt%、粒度为80目的鳞片状石墨时,金属结合剂金刚石磨具的磨耗比最大,达到206.62,并且力学性能良好,锋利度高。故其综合性能良好,具有较高的使用价值。
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.
