摘　　要：刃口崩缺状况是PCD刀具的主要质量指标,直接影响被切削表面的质量和刀具寿命。实验研究表明,PCD材料、磨削砂轮和磨削工艺参数对刃口崩缺都有不同程度的影响,正确选择PCD材料粒度、砂轮结合剂、砂轮粒度、砂轮转速、磨削压力和砂轮摆动频率可以有效控制刃口崩缺,提高PCD刀具的刃磨质量。Cutting edge collapse is the main quality index of PCD cutting tool,which has a direct impact on the quality of cutting surface and tool life. Experimental results show that the PCD material,grinding wheel and grinding process parameters have different effects on the cutting edge collapse. Using appropriate particle size of diamond powder,grinding wheel bonder,abrasive particle size of grinding wheel,speed of grinding wheel,grinding pressure and swing frequency of grinding wheel,cutting edge collapse can be effectively controlled,and grinding quality of PCD cutting tool can be improved.
