Cubic boron nitride (CBN) is a superhard material with the hardness second only to diamond. It not only has many excellent characteristics of diamond, but also has higher thermal stability and chemical inertness to iron group metals and their alloys. As an engineering material, it has been widely used in the processing industry of ferrous metals and their alloy materials. At the same time, it has been applied in a series of high-tech fields due to its excellent thermal, electrical, optical and acoustic properties, and has become a functional material with development prospects.
- Cubic boron nitride micron powder
Cubic boron nitride micron powder is used in precision grinding, grinding, polishing and super finishing to achieve high-precision processing surfaces. It is suitable for binder systems such as resin, metal, ceramic, etc. It can also be used to produce sintered polycrystalline composite sheet, and also could be used as loose abrasive particles and grinding paste. CBN has excellent chemical and physical properties, such as high hardness, high thermal stability and chemical inertness second only to diamond. As a super-hard abrasive, it has been widely used in the processing field of different industries. Now it is becoming an important materials that are indispensable to industries such as automobile, aerospace, mechatronics and microelectronics, there fore, it have received great attention from industrialized countries.
- Cubic boron nitride polycrystalline tools/Inserts
Cubic boron nitride polycrystalline (PCBN) tools /inserts are a type of superhard material products of CBN aggregates formed by agglomeration of many fine-grained (0.1-100 μm) CBN. In addition to its high hardness and high wear resistance, it also has the characteristics of high toughness, chemical inertness, red hardness, etc., and can be sharpened with a diamond grinding wheel. In all aspects of cutting, it shows excellent cutting performance and can achieve stable cutting at high temperatures. It is particularly suitable for processing hardened materials such as various hardened steels, tool steels, and chilled cast iron. The tool has sharp cutting, good shape retention, high wear resistance, small unit wear, few dressing times, and its conductive to automatic machining. It is suitable for all cutting operations from roughing to finishing. PCBN has been widely used in the CNC cutting industry and tool material with good development prospects.
