抄録

This paper presents the high performance and cost effective grinding method for hardened steel by cBN wheel with segmented grooves. The surface finishing with high accuracy must be done by fine grain grinding wheel, though the such fine grain wheel may often cause the burn out during grinding, so the grinding rate is limited thus the grinding performance is relatively low compared with the coarse and medium grinding. In this research, evaluation of the improvement on grinding performance by making separated gaps on the grinding wheel. Grinding forces, temperatures of specimen and surface roughness of finished work pieces were studied and the mechanism of burn-out prevention was considered.
