CBN (Cubic Boron Nitride) Tools are cutting tools used in CNC machining known for their exceptional hardness and thermal stability. CBN is synthesized in a similar process to synthetic diamonds but offers distinct advantages in machining ferrous materials and hardened steels.
Â
Advantages
Â
- High Hardness: CBN tools are second only to diamond in hardness, ensuring excellent wear resistance and prolonged tool life.
- Heat Resistance: Maintains hardness and cutting ability at high temperatures, making them ideal for machining hardened steels and difficult-to-machine alloys.
- High Precision: Capable of achieving tight tolerances and superior surface finishes, critical for precision machining applications.
- Extended Tool Life: Reduces tool changeovers and downtime due to longer operational lifespan and consistent performance.
- Versatility: Suitable for machining a wide range of materials including hardened steels, cast irons, and superalloys.
Â
Applications
Â
- Automotive Industry: Used for machining hardened steel components such as gears, shafts, and bearings in automotive manufacturing.
- Die and Mold Making: Applied in the production of molds and dies for plastics and metal forming industries requiring precise machining and high wear resistance.
- Bearings and Aerospace Components: Machining of aerospace parts, bearings, and turbine components where high precision and durability are crucial.
- Heavy Machinery: Utilized in machining parts for heavy machinery and equipment that demand resistance to wear and heat.
