Research and Exploration of Cemented Carbide Manufacturers
After years of research and exploration, my country has made great progress in superhard tools. However, the application of superhard tools in production is not extensive. The main reasons are as follows: manufacturers and operators do not know enough about the effect of hard turning with superhard tools. It is generally believed that hard materials can only be ground; the cost of tools is too high. The initial tool cost of hard turning is higher than that of ordinary cemented carbide mold tools (for example, PCBN is more than ten times more expensive than ordinary cemented carbide), but the cost allocated to each part is lower than that of grinding, and the benefit is more Ordinary cemented carbide is much better; there is not enough research on the machining mechanism of superhard tools; the specifications of superhard tool machining are not enough to guide production practice.
