Abstract

See full text

Disclosed are an additive raw material composition and an additive for superhard material product, a composite binding agent, a superhard material product, a self-sharpening diamond grinding wheel and a method for manufacturing the same. The raw material composition consisting of components in following mass percentage: Bi2O3 25%˜40%, B2O3 25%˜40%, ZnO 5%˜25%, SiO2 2%˜10%, Al2O3 2%˜10%, Na2CO3 1%˜5%, Li2CO3 1%˜5%, MgCO3 0%˜5%, and CaF2 1%˜5%. The composite binding agent is prepared from the additive and a metal composite binding agent. The self-sharpening diamond grinding wheel prepared from the composite binding agent has high self-sharpness, high strength, and fine texture, is uniformly consumed during the grinding process, does not need to be trimmed during the process of being used, and maintains good grinding force all the time, fundamentally solving the problems of long trimming time and high trimming cost of the diamond grinding wheel (FIG. 1).
