摘　　要：在分析聚晶金刚石 (PCD)材料的微观结构和去除机理的基础上 ,对PCD材料的超声振动研磨机理进行了深入研究。通过试验证明 ,采用超声振动研磨PCD可显著提高研磨效率 ,认为研磨轨迹的加长和超声振动的脉冲力作用是提高研磨效率的主要原因。Based on the analysis of microstructure and removal mechanism of PCD, the mechanism of ultrasonic vibration lapping for PCD is investigated. It is approved by the ultrasonic vibration lapping experiments that the efficiency of lapping PCD is improved obviously. It is presented that the increasing of lapping locus and impulsive force are prime reasons of increasing lapping efficiency.
