PublishedDate：2017-09-07
In 1957, the United States GE company first synthesized cubic boron nitride through untra-high pressure technology. In current times, ultra-high pressure high temperature synthesis is still the main method of obtaining Cubic Boron Nitride. Cubic boron nitride is a kind superhard material with many excellent properties. The cutting tools and abrasive tools made of cubic boron nitride have high hardness, thermal stability and chemical inertness, which will be widely used for machining a variety of ferrous metal materials and alloys, as well as tough processing materials and machinery industry.
At present, China's CBN materials have recognized by the customers from all over the world. The performance and the quality have reached the international level. And the production amount have occurred half market of the world. China CBN Materials have strong competitiveness.
China CBN product status
(1) High Production and New Materials
In recent years, China's cubic boron nitride production continues to improve, at the same time also emerged a large number of commercial enterprises to carry out cubic boron nitride tool trade. Halnn, as a pioneer of superhard materials, the previous Henan Institute of Superhard Materials, enjoyed a high reputation in the ultra-hard cubic boron nitride tool industry, and continue to develop new products to meet the needs of the market, thereby enhancing the Chinese super-hard tool in the world's reputation.
(2) Varieties Stable and Complete
After more than 10 years of rapid development, China's CBN not only leads the the sales amount, but also forms the stable varieties to lead the world. The following will share you some stable cbn materials grade:

International CBN Status
1.Sandvik Tool
Sandvik Hyperion, In recent years, launched new materials CBN300, CBN700, CBN200 and CBN VBR,CBNSP1S, on the base of the previous CBN Grade, such as CBN Type 1, CBN400, CBN500, CBN550 and CBN1000.
2.Element Six
Traditional CBN has ABN200, ABN300, ABN600,ABN800 , and recently years, it also add ABN700, ABN900 ect.
CBN Inserts
With the rapid development of modern manufacturing and high-speed cutting, hard machining, high stability processing and dry cutting and other advanced cutting the concept of deepening, it is to promote the rapid development of CNC machining technology and the general use of CNC machine tools can achieve high efficiency , High stability, long life processing of the super-hard material production and application are increasingly popular, The application of CBN tool Materials has grown rapidly year by year. Recently, the world's super-hard tool material consumption to 8% to 10% of the rate of growth, developed countries are more than 20% of the super-hard tool cutting tool market, however China's super-hard tool market share of less than 10%, which is a Big gap, but it has a lot of space. The future of cutting the mainstream of the cutting will be dry cutting, hard turning and high-speed cutting combined with high efficiency, low energy consumption, saving resources, reducing pollution, green cutting, as PCBN Insert has high hardness, high thermal stability, Good Chemical stability, good thermal conductivity, low coefficient of friction and a series of advantages, it shows that PCBN Material are the right tool materials for green manufacturing concept.
Conclusion
Cubic boron nitride has many advantages in the steel processing industry which can’t match the advantages of grinding and cutting applications, which has shown a superior performance, and will have wide development prospects at home and abroad. China cubic boron nitride variety, production and sales ahead, has become the world recognized big country. Through the synthesis of research, cutting-edge research and application of in-depth research, will eventually build China's cubic boron nitride power status.
