摘　　要：对硬质合金刀具和整体PCBN刀具高速重度断续切削多回转阀门执行器用方形铸铁端盖时的刀面磨损和切削性能进行了对比试验。根据试验结果并结合目前高速重度断续切削加工中存在的问题,确定选择整体PCBN刀具作为重度断续高速切削方形铸铁端盖的切削工具。最终加工实例验证了整体PCBN刀片在提高刀具使用寿命和切削效率方面的优良特性。The flank wear and cutting performance of carbide cutting tools and PCBN cutting tools in severe interrupt- ed cutting of square white cast iron end cover at higher speed are comparative studied in this paper. According to the test results and the problems in the severe interrupted cutting processing at higher speed, the solid PCBN cutting tools are se- lected to machine the square end cover which is made of white cast iron. At last, The excellent performance of the solid PCBN cutter in improving the life of cutters and cutting efficiency is proved by the successful example.
