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, three kinds of diamond grinding wheels were made by using polyimide resin powder, 939P resin powder and phenolic resin powder respectively. The grinding tests were carried out to measure the grinding wheel grinding ratio and grinding efficiency. The results show that the polyimide resin grinding wheel best wear resistance. Scanning electron microscopy was used to observe the microstructure of the grinding wheel, and the reasons for the different wear resistance of the three kinds of resin diamond grinding wheels were analyzed. With polyimide resin powder manufacturing, including diamond, CBN and other types of superhard abrasive, have achieved satisfactory practical application results.
