On November 1st, the Ministry of Science and Technology organized a national key project acceptance inspection meeting for the National Science and Technology Support Program “Development of Key Technologies and Equipment for Efficient and High-Precision Machining of Cemented Carbide Tools†in Beijing. The project was organized and implemented by Xiamen Science and Technology Bureau. For the key technical bottlenecks restricting the quality level of domestic high-efficiency and high-precision cemented carbide tools, 0.2-0.3 micron ultra-fine grained carbide and gradient carbide for coated CNC blades were developed. Research on the manufacture of high-performance cemented carbide materials and key technologies and equipment, tool design and manufacturing and coating of hard alloy tools such as 1 micron ultrafine-grain diamond coated tools and their required raw material powders. technology. The project has realized the localization of high-efficiency and high-precision cemented carbide tools, which has promoted the improvement of the technical level of cemented carbide tools in China. The expert group agreed to pass the acceptance of the project.
