Development trend of polycrystalline cubic boron nitride (PCBN) applications (2)
(1) The market demand has great potential.
(2) The update of working conditions such as machine tools has promoted the growth of PCBN tool applications.
(3) The characteristics of PCBN tools promote the use of growth. With the development of cutting speeds toward high and ultra-high speeds and the maturity of high-speed cutting processes, the use of PCBN tools will increase.
(4) From cost analysis. However, from the surface price point of view, PCBN tools seem to be more expensive than other tools, but the cost is reduced from the comprehensive analysis of reducing machine footprint, improving production efficiency, and avoiding tempering and hard processing. And with further scientific research, the manufacturing cost of PCBN tools is reduced, and the performance update will benefit users.
China has become a major producer in the world in the production of superhard materials such as diamond and CBN. CBN abrasive preparation, Henan has become the main base, Zhengzhou High-tech Zone Fenike and Nanyang Zhongnan Optical Instrument Factory, all of which are mass-produced and exported. However, domestic difficult-to-machine materials mainly rely on the import of tools and abrasive tools from GE, Sumitomo, and Showa Denko. South Korea has a fast research in this field. Henan Province has a leading position in CBN abrasive production and research. It is urgent to carry out research on CBN products and solve its key technologies and industrial production. The domestic market should be occupied as soon as possible to form a major production base.
In short, tool materials have been constantly updated and developed, and there is no end to it. There are also many scientific research departments in China that are stepping up the development of new PCBN composite sheets and PCBN polymers. The performance difference between PCBN tools and foreign countries is also shrinking. It is believed that in the near future, the development of PCBN tool applications in China will definitely be brought forward.
