随着科学技术的不断发展,硬脆材料(玻璃、光学玻璃、陶瓷、石英、铁氧体、锗、硅、各种晶体、宝石、金刚石等)的应用愈来愈广,常常需要利用这些材料制造各种零件和在零件上进行各种加工。一般说来,这些材料由于硬度高、脆性大、又不导电,加工比较困难。尤其是要在这类材料零件上加工出不规则形状的通孔和盲孔、深孔和螺纹,以及用成形 With the continuous development of science and technology, the applications of hard and brittle materials (glass, optical glass, ceramics, quartz, ferrite, germanium, silicon, various crystals, gems, diamonds, etc.) are more and more widely used and often require the use of these materials Manufacture various parts and carry out various processing on the parts. In general, these materials are difficult to machine due to their high hardness, high brittleness and non-conductivity. In particular, irregularly shaped through holes and blind holes, deep holes and threads are to be machined on such material parts,
