箱体类零件加工一般都需经平面加工,以及镗、扩、铰、钻及攻螺纹等工序。对于中小企业,孔系加工是工厂新产品开发中的薄弱环节。为此,我们介绍一种“上马”比较快的孔系加工工艺方案——普通车床改造为多孔镗床,供同行业在产品开发中参考。 1.方案设计 参见图1,在床头箱右侧的? Box parts processing are generally required by the plane processing, and boring, expanding, reaming, drilling and tapping processes. For small and medium-sized enterprises, Kong Department of processing is the new link in the development of new products factory. To this end, we introduce a “launched” relatively fast hole processing technology program - ordinary lathe into a porous boring machine for the same industry in product development for reference. 1 program design see Figure 1, in the right side of the bedside box?
