Abstract

The invention belongs to the technical field of micro electrochemical machining, and particularly relates to a micro electrochemical machining electrode, a machining method thereof, and a micro electrochemical machining device. The micro electrochemical machining electrode comprises a plurality of electrode sheets, the electrode sheets are sequentially arranged in a laminated mode to form an electrode sheet assembly, two-dimensional microstructures used for machining a workpiece are arranged at one ends of a plurality of electrode sheets in the electrode sheet assembly, and the two-dimensionalmicrostructures are arranged in one-to-one correspondence and define a three-dimensional chamber which is adaptive to the shape of a three-dimensional microstructure on the workpiece; and circulationgrooves are formed in the surfaces of one or more electrode sheets in the electrode sheet assembly, the first ends of the circulation grooves extend out of the corresponding electrode sheets, and thesecond ends of the circulation grooves communicate with the three-dimensional chamber. According to the micro electrochemical machining electrode, the timely renewal of an electrolyte and the rapid discharge of electrolytic products in a machining area are accelerated, a good machining environment is ensured, the situation that a ''dead water area'' appears when the surface of a complex microstructure is machined is avoided, and the machining and using requirements of the large-depth three-dimensional microstructure can be met.

Description

technical field [0001] The invention belongs to the technical field of micro electrolytic machining, and in particular relates to a micro electrolytic machining electrode, a processing method thereof, and a micro electrolytic machining device. Background technique [0002] Micro-electrolytic machining is a machining method based on electrochemical reactions to dissolve anodic workpieces to process three-dimensional microstructures. The tool electrode has no loss, can avoid defects such as fused layer, heat-affected zone and residual stress after machining, EDM and laser processing, and can process conductive materials of any strength and hardness. refer to figure 1 As shown, for the three-dimensional microstructure 31 on the micro-electrolytic machining workpiece 30, the micro-columnar electrode 40 is currently mainly used for layer-by-layer scanning electrolytic machining. Due to the small cross-sectional size of the micro-columnar electrode 40, its anti-interference abil...
