摘要
本文介绍了用聚酰亚胺树脂粉、９３９Ｐ树脂粉、酚醛树脂粉，分别制造三种金刚石砂轮，并对其进行磨削试验，测得其砂轮磨削比和磨削效率。结果表明，聚酰亚胺树脂砂轮的耐磨性能最好。通过扫描电镜观察砂轮的显微结构，分析了三种树脂金刚石砂轮耐磨性不同的原因。用聚酰亚胺树脂粉制造包括金刚石，ＣＢＮ等各类超硬磨具，均取得了满意的实际应用效果。
In this paper are presented three kinds of resin powders-polyimide resin, 939Presin and Phenolic resin, and they are used as bond for making diamond wheel. Grinding experiment shows that the wear resistance and grinding efficiency of polyimide resinoid bond diamond wheel are the best. By analysing the microstructre with SEM of the wheels, the causes of the difference are analyzed.
