Abstract: The invention provides an electrochemical discharge-assisted micro-grinding device for micro-components of brittle and hard materials. The device includes a micro-grinding tool, grinding fluid, a workpiece, an auxiliary electrode, a processing groove, and a pulsed DC power supply; the processing groove is filled with grinding fluid; the micro-grinding tool, the workpiece, and the auxiliary electrode are immersed in the grinding fluid; the micro-grinding tool is composed of a conductive grinding tool base, an electroplating layer, and insulated superabrasives. The micro-grinding tool is connected to the negative electrode of the pulsed DC power supply; the grinding fluid is composed of H2O2, Na2CO3, EDTA-Fe-Na, and deionized water; the workpiece material is brittle and hard; a large number of micro structures need to be produced on the surface of the workpiece.
