电解加工是利用工件与电极间电解液的电解作用,熔化部分工件而形成所需形状。通常电解加工是采用直流电进行的,工具作为阴极,工件接在阳极上,然后加上10伏左右的电压,电流密度取为20～200安/厘米~2。加工时工具没有消耗,在工件的底面出现了工具的雌形。过去,电解加工的缺点是:在工件上往往产生以电解液的循环孔为中心的幅射状条纹,因而利用此法不能完成最后一道精加工工序。最近日本三菱电机厂经过改进,制成一种新的电解加工机床。利用压缩空气混入电解液中,然后送至工具电极和工件之间。这时,压缩空气突然膨胀,使电解液中的
Electrolytic processing is the use of electrolyte between the workpiece and the electrode electrolysis, melting parts of the workpiece to form the desired shape. Usually electrolytic processing is the use of DC, the tool as a cathode, the workpiece connected to the anode, and then add about 10 volts, the current density of 20 ~ 200 A / cm ~ 2. Tool does not consume processing, the bottom of the workpiece appeared in the shape of the tool. In the past, the disadvantage of electrolytic machining was that radial striations centered on the circulation holes of the electrolyte were often produced on the workpiece, so that the final finishing process could not be accomplished by this method. Recently Mitsubishi Electric Works in Japan has been improved to make a new type of electrolytic machining machine. Using compressed air mixed into the electrolyte, and then sent to the tool electrode and the workpiece. At this moment, the compressed air suddenly expands to make the electrolyte
