Description

technical field [0001] The invention relates to a full-profile electrolysis system and method for blade full-profile electrolysis with cathodic feeding and annular liquid supply, and belongs to the technical field of electrolytic processing. Background technique [0002] Electrolytic machining technology is a special processing technology based on electrochemical principles. It uses the dissolution of metal anodes during electrochemical reactions to remove materials and process workpieces with specific sizes and shapes. Compared with general mechanical processing methods, electrolytic machining has the advantages of good surface quality, high processing efficiency, no mechanical cutting force, and no loss of tool electrodes. It has been widely used in aviation, aerospace, medical and other manufacturing fields. [0003] The blade is one of the core parts of the aero-engine, and its processing quality directly affects the performance of the aero-engine. In terms of materials...
