我厂在制造工作母机时,有很多刻度环(见圖1)要刻线和打字。过去这项工作首先是在平铣上利用分度头夹持工作物分度,再摇动铣床工作台一格一格地刻出线条,然后交给钳工在圆周等分上打出数字。这样不仅工作效率低,而且增加操作工人的劳动强度,同时还不能保证质量。现介绍一种在车床上进行滚线与滚字的工具如下。一、工具结构见圖2,心棒1装在车床主轴的锥孔内,动力 I plant in the manufacture of machine tools, there are many scale ring (see Figure 1) to engraving and typing. In the past, this work first used the indexing head to hold the indexing workpieces on the flat mills, then shaken the milling machine workbenches to engrave the lines on a grid and then handed them to the fitter to make figures on the circumference. This not only lowers the work efficiency, but also increases the labor intensity of the operating workers, but also can not guarantee the quality. Are introduced in a lathe on the roll and roll tools are as follows. First, the tool structure shown in Figure 2, mandrel 1 installed in the taper hole in the lathe spindle, power
