我公司调试机械压力机用刚性块(如图1),其两端面平行度要求0.03mm,四件等高要求0.05mm。如在卧式车床上一次车削加工完成,很难保证精度,往往需要增加磨削或刮研工序,生产效率很低。为此,我们采用了一种新工艺,使该件在卧式车床CW61100上一次加工完成,达到了设计精度。 My company commissioning mechanical presses rigid block (Figure 1), the parallelism of both ends of the surface requires 0.03mm, four pieces of contour requirements 0.05mm. Such as horizontal lathe on a turning is completed, it is difficult to ensure accuracy, often need to increase the grinding or scraping process, the production efficiency is very low. To this end, we have adopted a new process, so that the workpiece in a horizontal lathe CW61100 completed, to achieve the design accuracy.
