加工中心现已成为机械加工的一种重要手段,在使用过程中如何扬长避短,提高工件的加工精度,进一步扩大机床的加工能力,是一个具有实用价值和值得探讨的课题。 下面以附图所示的减速箱体加工为例,谈谈我们的作法。由附图可知,φ52H7孔底平面与箱体底平面24±0.016的尺寸很难保证 Machining center has become an important means of machining, how to avoid weaknesses in the course of use, improve the machining accuracy of the workpiece, to further expand the machining capacity of machine tools is a practical and worthy of discussion. Let’s take the example of the gearbox body shown in the attached drawing as an example to talk about our approach. As can be seen from the drawings, the φ52H7 hole bottom plane and the bottom of the box 24 ± 0.016 size is difficult to guarantee
