The main functions of CBN Cutter coating include extending the service life of the blade, improving production efficiency, enhancing the wear resistance and hardness of the tool, etc. Specifically, as follows:

1) Improve durability. CBN (cubic boron nitride) blade coating reduces diffusion and chemical reactions between the tool and workpiece by providing a chemical and thermal barrier, thereby reducing substrate wear. This coating has high surface hardness, high wear resistance, stable chemical properties, heat resistance and oxidation resistance, as well as lower friction coefficient and thermal conductivity.

2) Improve processing efficiency. CBN cutter coating can significantly increase cutting speed by 20% to 70%, improve machining accuracy by 0.5 to 1 level, and reduce tool consumption costs by 20% to 50%.

3) Enhance application scope. On ceramic and superhard material Cutter, coatings usually use materials with lower hardness to improve the fracture toughness of the blade surface, reduce blade breakage and damage, and thus expand the application range.

4) Improve thermal stability. CBN coating has higher thermal and chemical stability than diamond, and after oxidation in air, it forms a high-density  coating to prevent further internal oxidation.

5) Enhance optical and microelectronic applications. CBN coatings have good transmittance in the infrared to ultraviolet (including visible light) spectral range, making them suitable for use as some optical components.

The CBN coated Cutter produced by LINKUT company are widely used in the processing and manufacturing of quenched steel, automotive parts, and other industries, helping to reduce single piece processing costs.
