随着新产品的开发,对工件表面粗糙度要求越来越高,如我厂生产的高速线材轧机主轴要求表面粗糙度在R_o0.4以下,堆取料机φ360×2300油缸要求表面粗糙度为R_o0.8以下,而且油缸内孔越光越好。用普通的工艺方法,高效解决这些问题比较困难,因而我们采用电化学和机械复合加工这种特殊工艺方法,对轴类和孔分别进行试验,取得了良好的效果。一、复合加工原理如图1所示,电化学和机械复合加工的原理就是把工件做为阳极,阴极和阳极保持一定间隙,使电解液充满电极间隙,在通直流电的情况下,工件(阳极)被腐蚀,在表
With the development of new products, the workpiece surface roughness requirements are getting higher and higher, as I plant the production of high-speed wire rod mill spindle surface roughness below R_o0.4, stacker reclaimer φ360 × 2300 cylinder requirements surface roughness of R_o0.8 the following, and the cylinder bore the better light. It is difficult to solve these problems efficiently by ordinary process method. Therefore, we use electrochemistry and mechanical compound processing to process the shaft and hole separately, and achieved good results. First, the composite processing principle shown in Figure 1, the principle of electrochemical and mechanical composite processing is the workpiece as an anode, the cathode and the anode to maintain a certain gap, so that the electrolyte filled electrode gap, in the case of direct current, the workpiece (anode ) Is eroded at the table
