What is CBN cubic boron nitride insert？

CBN cubic boron nitride insert (Cubic Boron Nitride) is a tool material with excellent cutting performance and wear resistance. It is made of cubic boron nitride (CBN), which is a superhard material. Compared with traditional carbide inserts or coated inserts, CBN inserts show better performance when machining high hardness materials.The advantages of cubic boron nitride CBN tools are mainly reflected in their extremely high hardness and wear resistance. The hardness of CBN material is second only to diamond, so it can easily cut various materials with higher hardness, including engineering ceramics, high-speed steel, cemented carbide, etc. CBN inserts also have excellent wear resistance, even under high temperature and high speed cutting conditions, they can maintain a long tool life, reduce the frequency of tool replacement and improve production efficiency.

In addition to hardness and wear resistance, CBN inserts also have good thermal stability. In a high-temperature cutting environment, CBN inserts are not prone to thermal expansion, and can maintain good tool dimensional accuracy and cutting stability. This makes CBN inserts suitable for high-speed cutting and workpieces that require high machining accuracy.

The application range of CBN inserts is very wide. It is widely used in the cutting processing of high-hardness materials such as aerospace, automobile manufacturing, and mold processing. For example, in the manufacturing process of automobile brake discs, gray cast iron materials need to be processed. CBN inserts can stably cut under high temperature conditions with their excellent performance, improving work efficiency and processing quality.

All in all, CBN cubic boron nitride inserts have become important cutting tools in the field of high hardness material processing due to their excellent hardness, wear resistance and thermal stability. Its wide application has brought efficiency improvement and cost reduction to industrial production, and promoted the development of manufacturing industry.
