On the Fine Finishing by the High Frequent Abrasive Stone

Abstract

The surface of a abrasive stone may be considered to have a dence distribution of abrasive grains over the surface, however, the area occupied by the grains is rather small and almost all is a space. In the method of superfinish, using such stone, a finely finished surface is obtained in a comparatively short time by giving complicated multi-motions between the abrasive stone and the work, moreover increasing the area of contact between them. Hitherto, the frequency of about 2000 〓/mn has been suited for superfinish, however, from the above consideration it was expected to have a better result at a higher frequency. The frequencies of 3000∼300000 〓/mn were used in this research and the good surface finish was obtained.
