Something you should know about CBN inserts
CBN inserts, or Cubic Boron Nitride (CBN) inserts, are super-hard cutting tools used for machining high-hardness materials.CBN is a man-made super-hard material that is second only to diamond in hardness. It consists of nitrogen and boron atoms that form a cubic crystal structure, giving it extremely high hardness and thermal stability.CBN inserts are usually made from CBN particles through high temperature and high pressure sintering technology, and then combined with a metal matrix to form a tool with excellent cutting performance.
It is characterized by high hardness, high thermal stability, high wear resistance, chemical inertness and toughness.CBN's hardness is second only to diamond, and it can easily cut a variety of high hardness materials.It can still maintain high hardness and cutting performance at high temperatures, suitable for high-speed cutting and dry cutting.The service life of CBN inserts is 5 to 25 times longer than that of cemented carbide tools, greatly reducing the number of tool changes and sharpening.CBN has good chemical stability to a variety of metals and non-metallic materials, and is not easy to chemical reaction with the material being cut.
It widely used in a variety of fields that need to process high hardness and difficult to machine materials, such as:Military industry: for processing various high hardness alloys and composite materials. Automotive industry: plays an important role in the precision machining of engine, gearbox and other components. Metallurgical roll industry: used for processing rolls and other wear-resistant parts. Bearing industry: to improve the processing efficiency and precision of bearing raceways. Mold industry: to extend the service life of molds and reduce maintenance costs. Medical Device Manufacturing: Used to process orthopedic implants and dental instruments with high precision and high surface quality.
