Electrochemical machining process for array micro type hole

This invention discloses an electrochemical process method for processing array micropore of metal alloy material, combining photolithagraphic process, electric casting technique and precise electrospark wire-electrode cutting technique, which comprises the following steps: a) applying wire-electrode cutting or photolithographic electric casting technology to make array micropore; b) electrochemical expelling machining the metal alloy material; when processing array micropore with small form ratio, the space between said array micropore is filled with insulation paste; when processing micropore with big form ratio, there is no insulation paste filled, but the electrode side wall is covered with insulating film. The insulation process decreases the disadvantage of stray electric field in electrochemical machining.
