Abstract

The invention relates to an inserted sheet type composite tool and an electrochemical and mechanical composite machining device and a machining method thereof. The composite tool of the invention comprises an inserted sheet and a substrate. The inserted sheet is fixed on the substrate. The composite tool of the invention has the advantages of simple fabrication, easy replacement of the inserted sheet, adjusting the inter-electrode gap and the ratio of the electrolysis area and the grinding area of the machining process by adjusting the geometric parameter of the inserted sheet and the substrate, simultaneously adopting the little grinding particle as possible according to the material to be machined, and consequently achieving the higher surface roughness. The composite machining device of the invention comprises a mechanical movement mechanism, a control system and an electrolyte supply system, wherein the mechanical movement mechanism comprises a mechanism enabling the composite tool to do the self-rotation motion, and a mechanism enabling the composite tool to do the upward and downward, front and back, and left and right motion relative to the workpiece. The machining process of the invention utilizes the principle of electrochemical anode dissolution and the mechanical film scraping to remove the metal. For the difficult-machining material, the machining method has the advantages of small tool loss, high machining efficiency and high machining accuracy.

Problems solved by technology

[0006] In addition, at present, most of the tools for electrolytic grinding at home and abroad are grinding wheel type or copy type, and the general electrochemical machining is difficult to apply to the polishing of narrow gaps, deep grooves and other fields due to the large size of the grinding wheel.
