摘　　要：通过切削实验,研究了PCBN刀具切削淬硬轴承钢时刀具磨损形态及磨损机理。实验表明,PCBN刀具前刀面的磨损为月牙洼磨损,后刀面的磨损为机械磨损,其磨损程度与工件硬度呈非线性关系,并随着切削速度的提高磨损量减少。Study on PCBN tools' wear types and wear mechanism by cutting hardened bearing steel experiments. The experimental results show crater wear on the rake face and mechanical wear on the tool flank during cutting. The degree of wear and hardness of workpiece are nonlinear relation, wear extent will decrease by increase cutting speed.
