Recently, the “Eleventh Five-Year” National Science and Technology Support Plan “Key Technology and Equipment for Green Manufacturing”, undertaken by Lake Haijie (Hunan) Engineering Technology Research Co., Ltd., “metal base grinding wheel remanufacturing technology and device based on EDM” The project of R&D and application demonstration passed the acceptance test.

This topic is aimed at the consumption and remanufacturing of super-hard metal matrix grinding wheels used in large quantities in China's machine tools, tools, military and other industries. Based on national conditions, it aims at international advanced level, focusing on energy saving, fast, low energy consumption, high quality, environmental protection and market demand. The research on the key process technology of metal matrix grinding wheel remanufacturing based on EDM deposition was carried out, and the metal matrix grinding wheel remanufacturing device was developed. Solved a number of key technologies such as compressed powder electrode formulation, electrode preparation process, and electrospark deposition process of abrasive grain layer. Independent research and development of metal matrix grinding wheel remanufacturing device, electrode formulation and abrasive protection, metal/nonmetal Innovative in terms of spark deposition. He applied for 4 invention patents, has granted 1 patent, and published 12 papers.

The metal matrix grinding wheel remanufacturing device developed by this project has been put into trial use at Hunan Jieke CNC Grinding Machine Co., Ltd.
