近年来,各种硬齿面精加工方法在加工精度和加工效率上,都取得了一些进展,而且还出现了一些新的硬齿面精加工方法。一、硬齿面滚齿工艺由于磨齿效率低、成本高,七十年代以来,国外开始研究硬齿面滚齿工艺。采用硬质合金滚刀,可以提高加工效率。目前在日本、西德、苏联等国生产中已有应用。国内近年来也在积极研究硬齿面滚齿工艺,取得了一些进展,已在一些工厂生产中应用。北京第二机床厂、济南第一机床厂等一些厂家已采用硬齿面滚齿工艺代替粗磨齿,加工效率比锥面砂轮磨齿机约高5～6倍。硬齿面滚齿工艺要求滚齿机
In recent years, all kinds of hard tooth surface finishing methods have made some progress in the processing accuracy and processing efficiency, but also appeared some new hard tooth surface finishing methods. First, the hardened tooth hobbing process Due to low efficiency and high cost of grinding, since the seventies, foreign countries began to study hard tooth hobbing process. Carbide hob, can improve the processing efficiency. Currently in Japan, West Germany, the Soviet Union and other countries have been producing applications. In recent years, China is also actively studying hard tooth hobbing process, made some progress has been applied in some factory production. Beijing Second Machine Tool Plant, Jinan First Machine Tool Plant and some other manufacturers have adopted the hardened tooth hobbing process instead of coarse grinding teeth, processing efficiency than the conical grinding wheel about 5 to 6 times higher. Hardened hobbing process requirements hobbing machine
