Grinding Performance of Superabrasive Belts.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1996
The purpose of this study is to clarify the performance of high-efficiency belt grinding with superabrasive belts. Constant-load belt grinding of hardened SUJ2 steel was performed using CBN, diamond and alumina belts. Tangential force was measured using a small feather-type dynamometer, and stock removal, as well as decrease of height, was measured by ...
