Deng Fuming (professor, doctoral tutor) Deng Fuming , born in Zhangzhou , Hunan Province in 1963, is currently the director and professor of the Institute of Superhard Tool Materials of China University of Mining and Technology (Beijing), a doctoral supervisor of mechanical design and theory, and also serves as the national superhard material. Member of the Expert Technical Committee of the Association, Member of the Expert Committee of China Industrial Diamond Network, and Academic Committee of Beijing Key Laboratory of Nano-optoelectronics. The main research directions are superhard materials, carbon nanomaterials, crystal growth theory, powder metallurgy and ultra-high pressure technology. He has published more than 60 papers in official academic journals at home and abroad, 10 of which have been indexed by SCI, 15 by EI, and 2 have won provincial and municipal excellent academic paper awards. The paper has been cited more than 80 times by SCI papers. China University of Mining and Technology (Beijing) Superhard Tool Materials Research Institute China University of Mining and Technology (Beijing) Superhard Tool Materials Research Institute was established in 2005, specializing in the research and manufacture of superhard materials, carbon nanomaterials and powder metallurgy. After more than 6 years of research and experimentation, we have made major breakthroughs in PCBN tool materials. In 2007, we won the first prize of Science and Technology Progress Award of Chaoyang District of Beijing and the second prize of Science and Technology Progress of Ministry of Education in 2011. Especially in the past three years, the Institute of Superhard Materials of the University of Mines has achieved breakthroughs in the research under the support of national issues. The PCBN material tools currently developed have comparable performance with foreign advanced brands. We hope that by combining with the market, the domestic superhard material tool industry will develop faster.
Deng Fuming: PCD/PCBN tool development is the trend of the times
At present, the development status of PCD/PCBN tools at home and abroad Currently, foreign advanced countries have already put into use PCD/PCBN tools on a large scale, which is inseparable from the rapid development of foreign high-speed CNC machine tools in the past 20 years, especially in the automotive industry. Foreign PCD/PCBN tools have accounted for more than 30% of the tool market share. PCD/PCBN tools are especially suitable for CNC automatic machining line applications such as the automotive industry due to their high hardness, high wear resistance, good thermal conductivity and low friction coefficient. Compared with foreign countries, the current domestic PCD/PCBN tools are not well developed. This is due to the fact that the domestic tool companies are not equipped with the level of manufacturing equipment and manufacturing technology, which restricts the use and promotion of these tools; foreign PCD/PCBN tools are The expensive price causes many users to be discouraged; the use habits of enterprise technicians and the awareness of new technologies are not enough, and the tool performance, processing mechanism and using technology of PCD/PCBN tools are not fully understood and mastered. However, from the experience of foreign success, coupled with the advantages of high-speed, high-precision, car-based grinding and green manufacturing of PCD/PCBN tools in the field of machining, it will be like the development of high-speed CNC machine tools in China. The trend is unstoppable. Advantages of PCD/PCBN tools in the automotive industry The automotive industry is the best application area for PCD/PCBN tools. In recent years, with the continuous development of China's automobile industry, the automotive industry has become an important pillar of the national economy, PCD/PCBN tools. When used with high-speed CNC machine tools, it can shorten non-machining time to more than half, and also reduce non-machining time, increase machine tool life and improve machining efficiency. At present, foreign PCD/PCBN tools are used in the machining of cylinder blocks, cylinder heads, axles, gearboxes, bearing covers and other parts. For the shaft, gear and wear ring, the PCBN tool is very convenient for turning, and it is also a place that is well done abroad. Trends in PCD/PCBN tools We expect that during the 12th Five-Year Plan period, China's tool market share will reach almost 360 billion, according to the current market share of superhard materials accounted for more than 10%, within five years, PCD/PCBN The tool market share will reach nearly 4 billion, which is a huge cake to be developed for all superhard material tool companies. PCD/PCBN represents the development direction of tool materials and is an ideal cutting tool material. It is an inevitable trend to replace non-renewable and increasingly scarce carbide tool. It is believed that through the unremitting efforts of domestic enterprises and scientific research institutions, China's super-hard material Cutting Tools business will have a brighter future, and PCD/PCBN cutting tools will go farther and stronger in cutting processing.
