一、前言长期来磨削被用作表面光整加工的典型工艺。为了改善零件表面的应力状态和提高生产率,目前有相当一部分零件是以挤(滚)压熨平代替磨削作为表面的光整加工。本文主要介绍一种新的提高高硬度、强度的难加工材料零件表面光洁度的有效方法——电接触电阻加热挤(滚)压加工。通过实验研究了各工艺参 First, the preface Long-term grinding is used as a typical surface finishing process. In order to improve the stress state of the part surface and improve the productivity, a considerable part of the current parts are squeezed (roll) pressing instead of grinding as the surface finishing. This article mainly introduces a new effective method to improve the surface finish of difficult-to-machine parts with high hardness and strength-electrical contact resistance heating (squeeze). Through the experimental study of the process parameters
