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.

Abstract: Disclosed are a multi-channel electrochemical machining device and method for a blisk, and relate to the technical field of blisk electrochemical machining. The multi-channel electrochemical machining device for a blisk comprises an electrolytic bath used for accommodating an electrolyte, a blisk workpiece, a tube electrode and a top cover plate. The top cover plate is located above the blisk workpiece. An electrolysis chamber used for the tube electrode to electrolyze the blisk workpiece is formed between the lower surface of the top cover plate and the surface of the blisk workpiece. The electrolysis chamber communicates with the electrolytic bath. A drainage seam communicating the electrolysis chamber and the electrolytic bath along the axial direction of the blisk workpiece is formed in the upper surface of the top cover plate.
