以前,我们厂加工图1所示工件的刻线时,是在立式铣床上,用手摇动分度头和工作台手柄的方法,一条一条刻制出来的。这种加工方法,生产效率较低,两个人配合工作,八小时只能加工出二十个工件。后来我们采用了滚压刻线的方法。起初我们采用了一比一的连续式滚压形式,将刻线滚刀做成一百个刀齿与工件对滚。由于这种工件是在锥度比较大的圆锥面上刻线,工件刻线部位的径向尺寸很难加工 In the past, when we processed the engraved lines of the workpiece shown in Fig. 1, we engraved one by one on a vertical milling machine by manually shaking the indexing head and the handle of the workbench. This processing method, the production efficiency is low, two people work together, eight hours can only produce twenty parts. Later we used the method of rolling scribing. At first, we used a one-to-one continuous form of rolling the engraved hob into a hundred teeth and the workpiece roll. Because this kind of workpiece is engraved on the conical surface with larger taper, the radial size of the engraved part of the workpiece is difficult to process
