当前齿轮的发展趋势是以硬齿面代替软齿面,然而齿轮淬硬后,精度普遍降低1～2级乃至更多。要保证淬硬齿轮的制造精度,往往还要磨齿。然而磨齿工效低、成本高,而且由于技术和经济等原因,其应用受到一定限制。为了满足硬齿面加工需要,国内外都在致力于硬质合金齿轮刀具的开发,以便运用各种切削方法进行硬齿面的滚齿、插齿、剃齿和铣齿,其中硬齿面滚齿是最为成熟的工艺。 The current trend of the gear is to replace the hard tooth surface soft tooth surface, however, after the gear hardened, generally reduce the accuracy of 1 to 2 or more. To ensure the manufacturing precision of hardened gears, often grinding teeth. However, the work efficiency is low, the cost is high, and due to technical and economic reasons, its application is subject to certain restrictions. In order to meet the needs of processing hard tooth surface, both at home and abroad are committed to the development of carbide gear cutting tools, in order to use a variety of cutting methods for hobbing hobbing, gear shaving, shaving and milling teeth, Tooth is the most mature technology.
