管电极电解加工采用中空金属管作为阴极工具对工件进行电解蚀除，在深小孔加工方面具有独特优势。为了避免酸性电解液对环境造成的危害，管电极电解加工采用中性盐溶液替代酸性溶液作为电解液。通过研究初始加工间隙、进给速度、电解液压力、电参数对钛合金深小孔加工的影响，择优选取加工参数，在20 mm厚的TC4钛合金工件上加工出了深径比大于10的通孔。

Electrochemical drilling is a process using metal tube as the cathode tool,which has unique advantages in drilling of deep small holes. In order to avoid harm to the environment by acid electrolyte,the neutral salt solution is proposed to replace the acid electrolyte. This paper study experimentally on the effect of process parameters including the initial machining gap,tool feed rate,the pressure of electrolyte,pulse voltage,and pulse duty ratio. Finally,the deep small hole with the aspect ratio more than 10 is machined in the 20 mm-thick titanium alloy (TC4) by the optimum parameters.
