In the field of superabrasives, Cubic Boron Nitride Single Crystal (CBN) has become the first choice in many industrial fields due to its excellent performance and wide range of application prospects. Today, let's take an in-depth look at this amazing material with a special introduction to CBN abrasive products from BN(CHINA) Technology.
What is CBN single crystal?
Cubic Boron Nitride Single Crystal, or CBN for short, is a synthetic super-hard abrasive. Its hardness is second only to diamond, but its thermal stability is much higher than that of diamond.CBN consists of boron atoms and nitrogen atoms, and has a complex cubic/sphalerite structure, a structure that makes CBN abrasives extremely resistant to abrasion, corrosion and high stability.
Features and advantages of CBN abrasives
High hardness: the hardness of CBN is much higher than that of ordinary abrasives, so it can process all kinds of materials with high hardness and toughness, especially those that are difficult to be processed by ordinary abrasives.
Long service life: Because CBN abrasives have less abrasion, long service life and high grinding ratio, good economic benefits can be achieved.
High precision: When CBN abrasives are in use, the shape and size change more slowly, which is favorable for grinding operation and saves auxiliary working hours, and it is more suitable for automatic line processing of high-precision parts.
Low grinding force: CBN abrasives can maintain a sharp cutting edge, small grinding force, is conducive to improving the accuracy and finish of parts, while reducing the power consumption of machine tools.
Low grinding temperature: CBN abrasives have a low grinding temperature, which can greatly improve the surface quality of the workpiece and avoid defects such as cracks, burns, and organizational changes in the parts.
CBN Abrasive Products from BN(CHINA) Technology
BN(CHINA) Technology, as a full industry chain supplier of carbon nitride and boron materials, has decades of expertise in providing precision solutions for grinding applications. Its newly launched DL-8500 series CBN abrasive products have maximized the performance of CBN abrasives.
DL-8500 series CBN abrasive adopts a new formulation system, with highly active lithium-based multicomposite materials as the main catalyst, adding the appropriate amount of crystal inducer and crystal structure distortion factor, through the optimization of the process, so that the B, N atoms orderly deposition and growth, full exclusion, the formation of an orderly layered growth structure. This series of products have many crystal surfaces and are bright black, with sharp angles, higher strength and hardness, and good thermal stability.
In order to meet different application requirements, the DL-8500 series is subdivided into two products, DL-8500A and DL-8500B. DL-8500A has a complete and regular block structure with multiple and complete mirror surfaces, sharp edges and corners, and higher strength and thermal stability, which makes it suitable for aggressive grinding and metal-ceramic bonding systems. On the other hand, DL-8500B has an irregular block structure with more angles and a perfect combination of sharpness and self-sharpening, which is suitable for ceramic bond and high-strength resin bond systems.
