Abstract

The invention relates to an electrochemical corrosion processing method for micro-column group electrodes, which belongs to the field of electrolytic processing. The method comprises the following steps: (1) using electric discharge wire cutting or micro-milling technology to manufacture a group electrode blank with multiple single electrodes; (2) using finite element method to design and manufacture the cathode of an electrochemical corrosion tool; (3) The group electrode blank is used as an electrochemical corrosion anode, immersed in the electrolyte, so that each single column on the blank is completely below the liquid level; the electrochemical corrosion cathode and anode are placed vertically and parallelly; (4) power on, and the group electrode blank is Electrochemical corrosion processing uses constant voltage processing and charge method to control the shape and processing size of group electrodes respectively. The method of the invention has the characteristics of simple processing equipment and control mode, high processing efficiency and processing quality, and low manufacturing cost.

Description

technical field [0001] The electrochemical corrosion processing method of micro-cylindrical group electrodes of the invention belongs to the technical field of electrolytic processing. Background technique [0002] As a typical microstructure, microarray group holes are widely used in aerospace, precision instruments, chemical fiber and other fields, such as high-speed printer nozzle plate, optical fiber connector, chemical fiber spinneret, micro filter and electron microscope grating, etc. For the processing of micro-group hole structures, compared with conventional drilling, micro-electric machining has the advantages of no mechanical cutting force, high machining accuracy and efficiency, and can be processed on thin-walled, elastic parts and other low-rigidity workpieces. Therefore, It has broad application prospects in the processing of micro-porous structures. The machining of micro-cylindrical group electrodes is the key link to realize the micro-electromachining of g...
