Abstract
A new high-performance lapping tool consisting of short metallic fibers and epoxy resin was developed to overcome the low lapping performance of conventional tools for grinding difficult-to-cut materials. The short metallic fibers were compressed and impregnated with epoxy resin to produce the new lapping tool. By using these different wear-resistance materials, the tool surface could maintain the uneven shape continuously even when its surface was worn and this makes it possible to maintain long-term high lapping characteristics and enough effective slurry supply. In this research, we examined the optimization of the shape and the material of fibers. Moreover a 40 vol% fiber lap could be produced by using a coupling agent. The results of the tests showed that the lapping efficiency was improved by 28 % and that the durability was equal to that of the conventional cast-iron lap.
