在齿轮加工的领域中,采用切削加工的办法仍然是目前的主要方法,国外从五十年代后期,在中等模数、大批量齿轮的生产中,滚齿速度已经逐渐从原来的第一滚齿速度—50米/分以下提高到第二滚齿速度—80米/分左右。目前60～80米/分的滚齿速度已经得到广泛的应用,并且正在酝酿着第二次飞跃,使滚齿速度提高到硬质合金的切齿速度—200米/分以上。这样 In the field of gear machining, the use of cutting method is still the main method at present, from the late fifties in the country, in the middle modulus, high-volume gear production, hobbing speed has been gradually from the original hobbing Speed ​​-50 m / min or less to the second hobbing speed -80 m / min or so. At present, the gear hobbing speed of 60-80 m / min has been widely used, and a second leap is brewing, which increases the gear hobbing speed to cemented carbide cutting speed of -200 m / min. such
