我国采用混气电解加工解决锻模型腔的加工问题,已有多年的历史。这种方法与仿形铣削相比较。具有效率高、光洁度好、钳工修磨量小等优点;但也有工艺装备复杂、加工参数不好掌握,阴极设计困难等缺点。洛阳拖拉机厂、长春汽车厂、北京内燃机总厂、南昌柴油机厂和北京机床研究所联 China’s use of mixed air electrolysis processing forging die cavity processing problems, has many years of history. This method is compared with profiling. With high efficiency, good finish, fitter grinding a small amount of advantages; but there are complex process equipment, processing parameters are not good grasp of the cathode design difficulties and other shortcomings.
