Abstract:
1. An electrochemical processing apparatus, comprising: a spindle, providing linear feed; a reciprocating swing unit, connecting to the spindle; an electrode, connecting to the reciprocating swing unit; and a reciprocating twist and micro-vibrating unit, putting around the electrode; wherein the reciprocating twist and micro-vibrating unit includes: an inner ring, putting around the spindle; an outer ring, setting around the outer side of the inner ring, upper ends of the outer ring and the inner ring setting on a same horizontal plane; and a plurality of ribs, used for mounting a plurality of piezoelectric actuation devices on one side surface thereof, and connected between the outer ring and the inner ring, the piezoelectric actuation devices thrusting the plurality of ribs in a same direction simultaneously for driving the outer ring and the inner ring to perform the reciprocating twist and micro-vibration in a same vibration direction simultaneously, so the reciprocating twist and micro-vibration unit drives the electrode to perform the reciprocating twist and micro-vibration in a same vibration direction simultaneously.
