Industrial Applications of Cubic Boron Nitride

Cubic boron nitride (CBN) is a new type of artificial superhard materials after synthetic diamond, which is produced successfully in 1957 by using the method of static pressure catalyst that is similar to that of synthetic diamond.

In the late 1960s, plated CBN - Ⅱtype products are available, and most countries began to widely use. Our country made the samples in 1967, and in 1975, we began the industrial production. The developing course of cubic boron nitride is just like synthetic diamond. After they have the ordinary strength of products, they will further head to the direction of high strength, large particles, many varieties and specialized direction. At present, the purpose of CBN is focused on two aspects: One is the manufacture of abrasives products, and the other is to be made into polycrystalline materials used as tools.

Cubic boron nitride abrasives products have great grinding performance, which not only can process hard and tough materials, improve the productivity, strictly control the shape and dimension precision of workpieces, but also can effectively improve the quality of grinding workpieces and the surface integrity after grinding. Therefore, it can improve the fatigue strength of parts, prolong service life, and increase the working reliability.

And the production of cubic boron nitride abrasives has better advantages than ordinary abrasives in terms of energy consumption and environmental pollution. Therefore, expanding the production and application of cubic boron nitride abrasives products are inevitable trend of abrasives products and cutting tools development. Using cubic boron nitride abrasives products for grinding belongs to the emerging advanced manufacturing technology. Its complicated procedures and technical level are much higher than the traditional grinding technology.

It is generally believed that the cubic boron nitride is a great contribution to metal processing, which leads to revolutionary change of grinding. As a result, more and more factories are particularly interested in the application of cubic boron nitride.
