Problems solved by technology

[0005] However, when micro-scale wire electrodes are used to electrolytically process high-aspect-ratio microstructures, since the side gaps are usually reduced to micron or even submicron levels, if the electrolytic products during processing cannot be discharged smoothly, new electrochemical reaction ions cannot be processed in time. Supplementary, there will often be a short circuit, so that the processing cannot continue

Abstract

The present invention relates to a microdimesion wire electrode electrolytic machining method. It is characterized by that in the course of electrolytically microcutting metal material by using wire electrode it utilizes a microvibration device to make the wire electrode produce microvibration perpendicular to its feeding direction, so that it is favourable for discharging electrolytic product from machining gap so as to prevent the short circuit from producing and greatly raise electrolytic quality. Said microvibration wire electrode system is mounted on the Z-axis of numerical control machine tool and is formed from wire electrode frame, microdimension wire electrode mounted on the wire electrode frame and microvibation device.

Description

technical field [0001] The invention relates to a micro-scale wire electrode electrolytic processing method and a micro-vibration wire electrode system, belonging to the field of micro-electrochemical processing. Background technique [0002] Microfabrication technology is one of the most active scientific research directions in this century, and the microfabrication of metal materials has a wide range of development needs. For microsystems, in terms of unit systems such as propulsion, drive, execution, and transmission, it often involves the manufacture of tiny metal parts such as planar coils, microchannels, microgears, transmission shafts, arms, rudders, paddles, and reducers. . The existing micro-processing technology of metal materials still has great limitations and cannot meet the needs of development. Electrochemical machining technology is a subtractive manufacturing technology based on the principle of anodic dissolution, such as electrolytic machining. It has a...
