Combined electrode electrolytic and mechanical grinding and polishing combined machining device and method

The invention discloses a combined electrode electrolytic and mechanical grinding and polishing combined machining device and method and belongs to the field of electrochemical and mechanical combinedmachining. According to the combined machining device, a working liquid trough separately communicates with an oil reservoir and an electrolytic liquid tank, a combined electrode comprises at least one metal base diamond sub-electrode and at least one non-conductive polishing sub-electrode, electrolytic liquid is conveyed into a electrolytic clearance by an electrolytic liquid outlet on the metalmatrix diamond sub-electrode, and polishing oil is conveyed into a polishing clearance by a polishing oil outlet on the non-conductive polishing sub-electrode. A combined electrode is used for electrolytic grinding polishing combined machining, a conductive base diamond electrode sprays electrolytic liquid to electrolyze, grind and remove most working allowance, and a non-conductive polishing electrode achieves mechanical
