摘　　要：采用传统的工艺方式加工ＴｉＣ系钢结硬质合金表面难度大，表面质量不理想．采用ＥＬＩＤ磨削技术，可以用ＣＢＮ微粉磨料的铸铁基砂轮对各类钢结硬质合金进行精密、超精密镜面磨削．文中对不同加工方式加工的ＴｉＣ系钢结硬质合金表面质量状态及ＴｉＣ颗粒微浮凸形成机理进行了研究．ＥＬＩＤ技术除了可以提高加工精度外，还可以提高表面质量以及工件的可靠性和材料的使用性能．Adopting the traditional grinding process, it will be difficult and inefficient to grind TiC series steel matrix carbide alloys. Using ELID grinding technique, the cast iron bonded superhard wheel can be used to perform precise and ultra precise mirror grinding on varous steel matrix carbides. This paper conducts a comprehensive research on the surface quality of TiC series steel matrix carbide alloys with different grinding processes and on the forming machanism of micro relief on the workpiece surface. In addition to raising the machining accuracy, the ELID technique could also enhance the surface quality and workpiece's reliability and mechanical behaviors of material.
