Description

technical field [0001] The invention relates to the technical field of electrolytic machining, and more specifically, to an electrolytic milling device and a machining process with controllable electrolyte orientation. Background technique [0002] Electrolytic machining is a manufacturing technology that uses the principle of electrochemical dissolution of metal anodes to remove materials. It has many unique advantages, such as no tool loss, independent of material hardness, high productivity, good surface quality, and three-dimensional complex shapes can be processed. Electrolytic machining has become a key technology in the aerospace manufacturing industry and is widely used in the production of engine blades and other parts. Electrolytic machining has been used in many industries such as weapons, automobiles, medical equipment, electronics, and molds. However, in the process of electrolytic machining, the flow field of the electrolyte in the machining gap has a direct r...

AI Technical Summary

Problems solved by technology

However, in this solution, only hole-like parts can be processed. When electrolytic milling is performed, the electrolyte cannot be obtained in the gap in the processing direction, so that the surface of the workpiece cannot be electrolytically milled, and the electrolytic machining of large depth-of-cut structures cannot be realized, and high-pressure gas will hinder electrolysis. The liquid discharges the electrolytic product, which affects the stability of the processing process and the surface quality
