近年来一些工业发达国家在机械工业中已普遍使用硬齿面齿轮。我国的硬齿面齿轮也正在逐步推广。国外对精度较高(7级精度以上)的中模数(m2～6)硬齿面齿轮,通常是放在类似瑞士NZA型蜗杆形砂轮齿轮磨床上进行磨齿的。我国因此类磨床较少,故都采用滚齿→预剃齿→热处理→珩齿加工工艺。由于珩齿只能提高齿轮齿形的表面光洁度,不能提高齿轮精 In recent years, some industrialized countries in the machinery industry has been widely used hardened gears. China’s hard-surface gear is also being gradually promoted. Foreign high precision (7 above the accuracy of) in the modulus (m2 ~ 6) hardened gear, usually placed on a similar Swiss NZA worm gear grinding machine grinding. Therefore, fewer grinding machines in our country, so the hobbing → pre-shaved tooth → heat treatment → honing process. As honing can only improve the surface finish of the gear tooth shape, can not improve the gear fine
