Abstract

The invention relates to a conical electrolyte groove and a micro electrolytic wire cutting and piercing processing method, and belongs to the field of micro electrolytic processing. The micro electrolytic wire cutting and piercing processing method is characterized in that the conical electrolyte groove (7) is used. The upper end of the conical electrolyte groove is provided with a cylindrical groove body (7-1), and the lower end of the conical electrolyte groove is provided with a conical groove body (7-2); and a liquid inlet (22) is formed in the side surface of the upper cylindrical groovebody, and a liquid outlet (23) is formed in the bottom of the lower conical groove body. The cylindrical groove body (7-1) part makes an electrolyte flowing in a direct current mode move rotatably, and products around a processing channel are discharged fully; and the conical groove body (7-2) part makes a flowing fluid generate a flow rate in the vertical direction, the processed products in thechannel are further taken away, and the effect of electrolysis is enhanced. The conical electrolyte groove and the micro electrolytic wire cutting and piercing processing method can be applied to micro electrolytic wire cutting and piercing processing, the processing efficiency is high, and the processing quality is good.

Description

technical field [0001] The invention relates to a conical electrolyte tank and a fine electrolytic wire cutting and perforating processing method, which belongs to the field of precision fine electrochemical processing. [0002] technical background [0003] Electrolytic machining is an electrolytic machining method based on anodic dissolution to remove materials in the form of ions. It can be used for the processing of metal microstructures. Micro electrolytic machining uses micro electrodes and micro-energy power sources to achieve microstructure processing. The micro-electrolytic wire cutting technology uses a metal electrode wire with a diameter of micron as the cathode to electrolytically cut the workpiece to realize the formation of micro-slits and micro-structures. [0004] At present, scholars at home and abroad have conducted research on micro-electrolytic wire cutting technology. Through the improvement and optimization of the process method, the effect of micro-ele...
