Description

technical field [0001] The invention relates to a wire electrode tension control method and device for micro-electrolytic wire cutting, belonging to the field of micro-electrochemical processing. Background technique [0002] Micro electrolytic machining is a technology based on the principle of electrochemical ion removal to dissolve workpieces in a small amount. In theory, it can achieve the processing accuracy of a single atomic scale. It has the advantages of low cost, has nothing to do with material hardness, and does not generate processing stress. There is huge potential for development. Micro-electrolytic wire cutting is a new type of micro-electrolytic processing technology that combines the principle of electrolysis and wire cutting. Since the wire electrode has no loss, micron-diameter metal wires can be used as electrodes to process slits as small as several microns. [0003] The wire electrode is a tool for micro-electrolytic wire cutting. Its diameter directly...
