过去,我厂在普通车床上加工图1所示工件上的两条挡圈槽时,将工件装在专用的夹具上,用专用刀具进行加工,由于工件较大,专用夹具笨重,对机床磨损较大。现在,做了如图2所示的偏心工具,可以在立钻上加工,工件夹紧在工作台上,这样,减少了机床磨损。 In the past, I plant in the ordinary lathe machining shown in Figure 1 on the two pieces of retaining ring groove, the workpiece mounted on a dedicated fixture, with a dedicated tool for processing, due to larger workpieces, heavy fixtures for the machine tool wear and tear Larger. Now, as shown in Figure 2 eccentric tool, you can drill in the processing, workpieces on the table clamping, thus reducing machine wear and tear.
