Abstract

The invention relates to trickle electrochemical machining. The liquid level of the electrolyte cell is lower than the machining surface, extracting electrolyte form the cell using its pump, using special electrode nozzle to introduce the electrolyte flowing slowly to the machining area along the radial of the tool electrode and finally returning back to the electrolyte cell from the machining area. The special electrode is made of nozzle clamper, electrode annular tube, nozzle liner and nozzle bushing. It can improve the machining stability, machining precision and micro degree.

Description

technical field [0001] The invention relates to a micromachining method for electrolyte axial flow and a special electrode nozzle thereof, belonging to the technical field of microelectrolytic machining. Background technique [0002] At present, there is an urgent need for micro-processing technology for precision micro-electromechanical devices, and electrolytic processing technology is very suitable for the requirements and characteristics of micro-processing. Due to the small amount of material removal and small size of micro-electrolytic machining, in order to control the stray corrosion of electrolytic machining, the inter-electrode gap between electrodes is only tens of microns; therefore, the machining gap is easily blocked, resulting in short circuit and damage to tool electrodes. In order to prevent the processing product from forming precipitates and blocking the processing gap, a low-concentration acidic electrolyte can be selected to make the product of the elect...
