  • Abstract:In order to improve the processing of cemented carbide ball valve, a pore forming agent was introduced into the resin diamond grinding wheel. Through the analysis of mechanical properties, he analysis of micromorphology of specimens by SEM , and the analysis of grinding performance, the hardness of hollow glass spherical pore forming agent and resin spherical pore forming agent on the properties of resin diamond grinding wheel was studied. The results show that with the increase of pore forming agent content, the flexural strength of the grinding wheel gradually decreases, and the influence of the two pore forming agents on flexural strength is basically the same. The hardness of the grinding wheel gradually decreases with the increase of the pore forming agent content, but the influence of hollow glass balls on the hardness of the grinding wheel is significantly greater than that of resin balls. Through the grinding performance, it can be seen that the processing of the pore forming agent significantly improves the sharpness of the grinding wheel, and the grinding wheel with a volume fraction of 15% of the hollow glass ball and the grinding wheel with a resin ball volume fraction of 20% have the best comprehensive performance, and the comprehensive performance of the latter is better than the former.
