PROBLEM TO BE SOLVED: To obtain an electrolytic grinding device by which a large quantity of small parts can be almost uniformly ground at once in a short time. SOLUTION: The electrolytic grounding device is constituted of a rectangular housing cylindrical vessel 10 formed of a first electrode member 11 serving as a anode in a current carrying condition, an electrolytic cell 2 holding an electrolytic grinding solution, a driving means rotating the rectangular housing cylindrical vassel in the electrolytic cell 2, and second electrode members 3 arranged at both sides of the rectangular housing cylindrical vessel 10 in the electrolytic cell 2 to serve as cathodes in a current carrying condition. The vessel 10 is kept in a current carrying condition in the electrolytic grinding solution of the electrolytic cell 2 to be rotated for a specified time. The electrolytic grinding can be adapted to the grinding work for small parts in place of a chemical grinding. Reduction of processing time and production cost can be realized. Further, the corrosion resistant of a grinding face can be improved and a glossy surface can be obtained. Moreover, superfluous finishing processes for small parts are dispensed with.
