The use of iron-based combination of diamond grinding wheel with a dedicated high-frequency pulse power supply, the steel knot carbide (GT35) online electrolysis dressing (ELID) precision grinding. The grinding mechanism of the ELID ultra-precision mirror grinding heterogeneous heterogeneous material steel cemented carbide surface was analyzed. The microscopic surface morphology of the surface was analyzed by atomic force microscopy. The results show that the use of ELID grinding technology to solve the carbide parts of ultra-precision grinding, grinding of steel bonded carbide surface roughness up to nanoscale, Ra ≤ 20 nm, and to ensure that the steel knot Geometric accuracy of carbide parts
