硬质合金刀具在金属切削加工上日益广泛地被应用,对如何提高硬质合金刀具的刃磨质量,不断提高生产率和零件加工质量,已成为迫切需要解决的问题。目前各厂采用碳化硅或金刚石砂轮进行硬质合金刀具的粗、精磨削,砂轮损耗大,刃磨工序繁,磨削时产生热,容易使刀片出现裂纹、烧伤、崩刃等现象,且刃磨质量差,效率较低。金刚石砂轮磨削时虽能获得较高的表面质量,但砂轮价格贵,有一定的局限性。硬质合金刀具的电解磨削是克服机械磨削缺点,稳定获得▽▽▽▽10以上光洁度的一种有效加工方法。现介绍如下。
Carbide cutting tools in the increasingly widespread application of metal cutting, how to improve the quality of carbide cutting tool grinding, and continuously improve the productivity and quality of parts processing, has become an urgent problem to be solved. At present, each factory uses silicon carbide or diamond grinding wheel for coarse and fine grinding of carbide cutting tools, large loss of grinding wheel, frequent sharpening process, heat generated during grinding, easy to make the blade appear cracks, burns and chipping, etc. Sharpening poor quality, low efficiency. Although the diamond grinding wheel can get higher surface quality, but the grinding wheel is expensive, there are some limitations. Electrolytic carbide cutting tool is to overcome the shortcomings of mechanical grinding, stable access to ▽ ▽ ▽ ▽ more than 10 smooth finish an effective processing method. Now introduced as follows.
