1963年七月,在我厂的产品部件中,有一种模数6的四头蜗轮。根据我厂过去经验都是在滚齿机上采用“单头飞刀”加工,对于多头蜗轮是用加工完一个头后,退出刀具,然后转动工作台进行分度(分度头)再加工第二、第三、第四个头。这次开始时也按这种方法加工,结果加工了两个都废了。 In July 1963, there was a four-headed worm wheel with a modulus of 6 in the product parts of our factory. According to the past experience of our factory, we adopt the “single-headed flying knife” on the hobbing machine, after the one is finished with the multi-headed worm wheel, exit the tool, then rotate the working table to re-process Second, third, fourth head. The beginning of this method is also processed, the result of processing two are scrapped.
