High speed grinding has long been considered one of the most effective methods for improving productivity of manufacturing lines. This study applies ultrahigh speed CBN grinding technology to develop a cam profile grinding machine capable of dramatically exceeding the machining efficiency of conventional cam grinders. This paper evaluates the characteristics of a chilled casting ground in experiments carried out with an ultrahigh speed surface grinding machine allowing operation at a wheel peripheral speed up to 200 m/s. An equation expressing the relationship between grinding force and grinding conditions : wheel peripheral speed, wheel depth of cut, and grinding wheel diameter, was developed. In addition, grinding power consumption was demonstrated to be independent of wheel peripheral speed, and to be defined only by grinding stock removal rate. Furthermore, the increase in wheel peripheral speed from 80 m/s to 200 m/s, both doubled grinding efficiency and decreased both the grinding force required and wear of the grinding wheel.
