Technology of Insulator Coating Components in Electrochemical Discharge Hole Machining

This article studied the theory and five processes of electrochemical discharge machining （ECDM） on insulator coating components, including the characteristics of voltage and current wave- forms of five processes. Trying different feed speeds and machining voltages, three different mechani- cal status of hole machining, such as insulator coating machining, transition machining and metal matrix machining are analyzed. To improve the processing efficiency and quality. The experiment of ECDM hole machining was done on zirconia coating material which metal matrix is titanium alloy and this method was proved feasible.
