摘　　要：通过对PCBN刀具切削不同硬度GCr15轴承钢时切削力、切削温度、刀具磨损和已加工表面质量的试验研究,得到了工件硬度对上述各量的影响规律.结果表明,当工件硬度在HRC50左右时,刀具磨损严重且工件表面质量很差,说明PCBN刀具不适合切削中等硬度的轴承钢.Based on experimental study of cutting force,cutting temperature,cutting tools wear and workpiece surface quality of PCBN cutting tools cutting GCr15 bearing steel of different hardnesses,the influence law of workpiece hardness on above factors is obtained.The results show that the cutting tools wear seriously and surface quality of workpiece is poor when the workpiece hardness is about HRC50;it is shown that the PCBN cutting tool doesn＇t fit cutting medium hardness bearing steel.
