BARREL-POLISHING POLISHING BODY, BARREL POLISHING METHOD, AND MANUFACTURING METHOD FOR THIS POLISHING BODY

摘要

PROBLEM TO BE SOLVED: To provide a barrel-poling polishing body having a high cutting capability without more roughening the surface of a workpiece than necessary in a barrel-polishing polishing body.;SOLUTION: A polishing body M is a sinter body where polishing material particles G are coupled with one another by a coupling body B formed by the fusion or semi-fusion of particles of the same quality. The main component of the coupling body B is a material different from that of the polishing material particle G, and the rigidity of the coupling body B is lower than that of the polishing material particle G. A polishing method by this polishing body M includes a step where the polishing body M comes in contact with a workpiece, a step where the coupling body B absorbs the collision energy upon the contact of the polishing body M with the workpiece, and where the polishing material particles G cut the workpiece, and a step where the polishing material particles G located on the outer surface of the polishing body M are desorbed.;SELECTED DRAWING: Figure 5;COPYRIGHT: (C)2019,JPO&INPIT
