Abstract: The present disclosure provides an electrochemical machining device and a method for a blisk using an electrode array, which relate to the technical field of electrochemical machining. The electrochemical machining device comprises an outer ring-shaped rotating ring, an inner ring-shaped base and a plurality of cathode rods. An inner diameter of the outer ring-shaped rotating ring is larger than an outer diameter of the inner ring-shaped base, and an inner diameter of the inner ring-shaped base is larger than an outer diameter of the blisk. The outer ring-shaped rotating ring and the inner ring-shaped base are coaxially arranged. Middle parts of the cathode rods are connected with the inner ring-shaped base, outer ends of the cathode rods are rotatably connected with the outer ring-shaped rotating ring, and inner ends of the cathode rods are provided with trepanning cathode pieces or radial feeding electrodes.
