美国通用电气公司发明的电解液喷流钻孔的方法,可加工φ0.13～0.51毫米的小孔,采用300～600伏的高电压。发现这种方法有两个困难问题:(1)加工出的小孔有喇叭口,即电解液进口的一端大;(2)喷咀端有严重磨损,原因不明,到一定时期就需要更换。TRW公司提出了采用脉冲电源进行加工,可以(1)得到均匀的小孔;(2)减少 The method of electrolyte jet drilling invented by General Electric Company in USA can process φ0.13 ~ 0.51mm small holes and adopt 300-600V high voltage. It has been found that this method has two difficult problems: (1) the processed hole has a bell mouth, that is, one end of the electrolyte inlet is large; (2) the end of the nozzle is severely worn for unknown reasons and needs to be replaced until a certain period of time. TRW proposed the use of pulse power for processing, you can (1) get uniform holes; (2) to reduce
