A micro Electrochemical Machining (ECM) system has been developed, and macro/micro complex feed mechanism presented in order to achieve high-resolution. nanosecond pulse power supply for micro-ECM the minimum width can reach 50 ns. Complementary chopper circuit designed avoid waveform distortion, which higher frequency. series of ECM experiments using machining have carried out, results tests proved that high-resolution spindle, high frequency, short help better quality surface, accuracy.
