选用PCBN刀具精车淬硬钢,其工件硬度高于45HRC,效果最佳。其切削速度通常为80~120m/min,工件硬度越高,切削速度宜取低值,如车硬度为70HRC的工件,其切削速度宜选60~80m/min。精车的切深在0.1~0.3mm,进给量在0.05~0.025mm/r,精车后的工件表面粗糙度为Ra0.3~0.6μm,尺度精度可达0.013mm。若

(Choose PCBN tool finish turning hardened steel, the workpiece hardness is higher than 45HRC, the best effect. The cutting speed is usually 80-120m/min. The higher the hardness of the workpiece, the lower the cutting speed should be. For example, the cutting speed of a workpiece with a turning hardness of 70HRC should be 60-80m/min. The depth of cut of the finishing turning is 0.1~0.3mm, the feed rate is 0.05~0.025mm/r, the surface roughness of the workpiece after finishing turning is Ra0.3~0.6μm, and the dimensional accuracy can reach 0.013mm. like)
