去年,我们在C620-1普通车床上,加工某一产品零件,其台阶深度为1.75±0.O3毫米,使用普通卡尺、深度卡尺及深度百分尺来测量,感到很困难,一是被测表面积小,二是读数速度低并且误差大。因此,我们采用了如图1所示的简易装置,装上百分表后,就可准确而迅速地在加工中测出工件的实际尺寸,直到现在还在使用。根据这一实践,对每一只百分表,都可参照图2所示装置,自制几个零件用来作测深度
Last year, we worked on a C620-1 lathe to process a product part with a step depth of 1.75 ± 0.03 mm, which was difficult to measure using a normal caliper, depth caliper and depth scale. Small surface area, the second is the reading speed is low and the error is large. Therefore, we used a simple device shown in Figure 1, fitted with a dial indicator, you can accurately and quickly measure the actual size of the workpiece, until now still in use. According to this practice, for each dial indicator, can refer to the device shown in Figure 2, made of several parts used to measure the depth
