Abstract: The bearing steel such as 100Cr6 offers many desirable characteristics for industrial use in terms of its excellent qualities of high hardness, high wear resistance and high contact fatigue strength. For the usage in the bearing, cylindrical grinding should be adopted to machine 100Cr6. In order to ensure processing quality and processing efficiency, it is necessary to carry out high speed grinding. Therefore, the orthogonal experiments of high speed cylindrical plunge grinding (HSCPG) were carried out on the annealed 100Cr6 with a ceramic bonded cubic boron nitride (cBN) grinding wheel, to study the effects of grinding wheel speed, workpiece speed and grinding depth on the grinding force, grinding temperature, surface roughness, surface morphology, surface hardening and deteriorative layer. The study demonstrates that a larger material removal rate and a better surface integrity can be achieved simultaneously by a large grinding wheel speed, a moderate workpiece speed and grinding depth.
