通过PCBN刀具切削淬硬轴承钢GCr15的试验研究，讨论了切削速度、进给量和背吃刀量三要素对表面粗糙度、表面硬度、硬化层深度、残余应力等表面完整性因素的影响规律，从而得出了使用PCBN刀具实施以车代磨的可行性结论．
The experiment research of cutting hardened bearing steel GCr15 by PCBN cutting tool, the influence law of the surface integrity, such as surface roughness, surface hardness, depth of hardened layer and residual stress , Which concluded that the use of PCBN cutter to implement the feasibility of the vehicle on behalf of grinding.
