Domestic Application Of Polycrystalline Diamond Tools

 The domestic PCD tool market continues to expand with the development of tool technology. China FAW Group has more than 100 PCD turning tools use points, and many wood-based panel companies also use PCD tools for wood product processing. The application of PCD cutting tools has further promoted the research on its design and manufacturing technology. Domestic Tsinghua University, Dalian University of Technology, Huazhong University of Science and Technology, Jilin University of Technology, Harbin Institute of Technology, etc. are all actively carrying out research in this area. There are dozens of companies engaged in the research and development and production of PCD tools in China, such as Shanghai Schuberhardt, Foshan Bangna, Changzhou Merck Tools, Zhengzhou Xinya, Nanjing Leitz, Shenzhen Runxiang, Chengdu Tool Research Institute, Chengdu Dimengdi and so on. The processing range of PCD tools has expanded from traditional metal cutting to stone processing, wood processing, metal matrix composites, glass, engineering ceramics and other materials. Through the analysis of the application of PCD tools in recent years, it can be seen that PCD tools are mainly used in the following two aspects: ① Processing of non-ferrous metal materials that are difficult to process: When ordinary tools are used to process non-ferrous materials that are difficult to process, the tools tend to be easily worn and the processing efficiency is low. Defects, and PCD tools can show good processing performance. For example, PCD tools can be used to effectively process a new type of engine piston material-hypereutectic silicon aluminum alloy (a breakthrough has been made in the research on the processing mechanism of this material). ②Processing of difficult-to-process non-metallic materials: PCD tools are very suitable for the processing of difficult-to-process non-metallic materials such as stone, hard carbon, carbon fiber reinforced plastic (CFRP), and man-made plates. For example, Huazhong University of Science and Technology realized the use of PCD tools to process glass in 1990; laminate flooring and other wood-based panels (such as MDF) have become more widely used. Processing these materials with PCD tools can effectively avoid defects such as easy wear of tools.
