Abstract: Based on analyzing the characteristic of MWEDM (Micro wire electrical discharge machining), the key techniques are studied for meeting the needs of high precision and surface integrity. The pulse generator with micro energy, constant tension winding system, micro driven servo feed system based on piezoelectric ceramics motions, leaning towards to open control strategy, intelligent technological project and the characteristic of fluid are researched especially. Therefore the problems of hardly cutting micro complex part are solved, and high quality micro part is obtained, then the demand of MWEDM is met ultimately.

Key words: Micro part, Pulse generator, MWEDM
