提出了一种以金属管为阴极、工件为阳极的复合式电化学放电打孔方法。弱导电性的液体在金属管和工件之间高速流动。放电主要发生在正面间隙，电化学过程发生在正面间隙和侧面间隙。在侧间隙处通过放电产生的重铸层可以被电化学去除。通过设计的透明夹具观察了差距处的加工现象，记录了加工过程中的电压和电流波形，分析了加工产物和重铸层去除效果。分析了孔的截面形状和加工表面，并与其他工艺的刀具磨损和加工效率进行了比较。最后，可以生产直径为0.5 mm的4 mm深的孔，刀具磨损低，几乎没有重铸层。
This paper presents a hybrid electrochemical discharge drilling method in which a metal tube is used as cathode tool and workpiece is used as anode. Liquid with weak conductivity flows at high speed between the metal tube and workpiece. Electrical discharge takes place mainly at the frontal gap, and electrochemical process takes place at both the frontal gap and side gap. The recast layer generated by electrical discharge at the side gap can be removed electrochemically. The machining phenomenon at the gap was observed through a designed transparent clamping fixture, voltage and current waveforms during machining were recorded, and the machining products and removal effect of recast layer were analyzed. The cross section of the hole and machining surface were analyzed, and the tool wear and machining efficiency were compared with those of other processes. Finally, the 4-mm-deep hole of 0.5-mm diameter can be produced with low tool wear and almost no recast layer.
