摘　　要：采用金属结合剂金刚石砂轮对T15工具钢进行成形磨削加工实验,获得了形面精度保持性好的成形磨削砂轮,并用其进行长时间磨削加工,得到了满足形面加工精度要求的加工试件。实验表明,采用电火花修形方法对金属结合剂砂轮进行精密修形,可获得满足成形磨削加工要求的砂轮轮廓;在成形磨削过程中,凹槽侧面磨损率始终最大,而砂轮回转面的磨损最为稳定。The experiment of forming tool steels T15 by metal-bonded diamond grinding wheels,obtaining the accurate and good shape of grinding wheel,using which after a long time grinding,the specimens has been shaped which can meet the requirements of surface machining accuracy.The results show that the wheel contours can be got,meeting the forming grinding requirements,by EDM methods precisely modify metal-bonded grinding wheel.In the forming grinding process,groove side wear rate is always the greatest,while the surface of rotary grinding wheel wear the most stably.
