The difficulty of high-precision and high-efficiency dressing of multi-grooved and small-arc- shaped grinding wheels seriously limits its application in precision grinding. The principle of electrode Electrical Discharge Machining (EDM) concave small circular arc-forming grinding wheel is expounded in this paper. The optimal combination of processing parameters is designed through single-factor experimental research. And the V-groove contour shape corresponding to the copper electrode turning grinding wheel is trimmed by a high-precision turning tool device. The EDM multi-groove small circular arc forming grinding wheel research is carried out step by step to reduce energy, the 2 500# and 1 000# particle size diamond grinding wheel forming and dressing verification is completed, and the graphite sheet specimen is ground for testing. The experimental results show that the proposed method controls the surface quality and contour accuracy of the grinding wheel under high efficiency, which has a guiding effect.
