Abstract

The microelectrode, used in electrochemical machining (ECM), is fabricated online by electrical discharge machining (EDM) currently. The machining efficiency of the microelectrode is low and the surface roughness of the microelectrode is bad. So the fabrication technology of microelectrode is applied by high frequency short pulses ECM. The chemical reaction of electrochemical machining was expatiated firstly. The non-passivated electrolyte and high frequency short pulses are adopted. Then the project of electrochemical machining was made. After the technologic experiment analyzed, a microelectrode with nice surface was fabricated successfully. The surface property, microhardness and composition, fabricated efficiency, and the machining capability of the electrode were compared with the electrode fabricated by EDM. The superiority of the electrode fabricated by ECM is showed fully. The practicability and reliability are proved by experimental investigation, thus the theory of ECM is enriched.
