硬质合金刀具研磨是比较困难的工序,目前都采用碳化硼或碳化硅粉加工。当表面光洁度要求10时,就很难达到。我们在加工金钢镗刀时,切削刃要求10,曾经采用325# 、400# 、600# 的碳化硼进行研磨试验,结果达不到要求,而且效率很低。 经过杂志介绍,我们试制和试验采用石墨导电砂轮在 Carbide cutter grinding is a more difficult process, the current use of boron carbide or silicon carbide powder processing. When the surface finish requirements of 10, it is difficult to achieve. When machining the boring tool, the cutting edge requires 10 and has been subjected to the grinding test with 325 #, 400 # and 600 # boron carbide. The result is unsatisfactory and the efficiency is very low. After magazine introduction, we trial production and test using graphite conductive wheel
