Optimum Grinding Condition of BORAZON CBN Grinding Wheel analyzed through Grinding Mechanism

Abstract

An optimum grinding condition was found by making clear the relation between the grinding performance of CBN grinding wheel and the grind-ing mechanism. Following results are obtained : (1) Considering cutting and slipping areas, the limited stock removal per wheel circumferential length is expressed as functions of grain depth of cut and arc of contact. (2) The optimum grinding condition is determined by the intersection of these functions. (3) The optimum peripheral speed of workpiece must be lowered as the stock removal rate increases.
