采用新型刀具材料可为切削加工开辟新的加工领域,其优点: 1、可大大提高切削加工生产效率; 2、可提高零件的加工表面质量,尤其立方氮化硼等刀具加工淬硬钢代替磨削加工时,可使工件表面产生残余压应力,因而可提高零件的疲劳强度; The use of new cutting tools for cutting materials to open up new areas of processing, its advantages: 1, can greatly improve the efficiency of cutting production; 2, can improve the quality of parts processing surface, in particular, such as cubic boron nitride tooling hardened steel instead of grinding Cutting processing, the workpiece surface can produce residual compressive stress, which can improve the fatigue strength of the parts;
