Niobium nitride coated (NbN) carbide inserts are carbide inserts with a niobium nitride film coated on the blade surface. Niobium nitride is a ceramic material with excellent hardness, wear resistance and chemical stability.
The main features of niobium nitride coated inserts are as follows:
High hardness: Niobium nitride has extremely high hardness, which can reach 1500-2000HV, giving the blade excellent wear resistance and cutting performance.
Excellent heat resistance: Niobium nitride coating can maintain stable performance in high-temperature environments, resist high-temperature thermal expansion and thermal shock, and is suitable for high-temperature cutting.
Low friction coefficient: Niobium nitride coating has a low friction coefficient, which reduces friction and heat accumulation during cutting, reduces cutting force and cutting temperature, and extends tool life.
Good chemical stability: Niobium nitride coating has good chemical stability and can resist chemical corrosion and oxidation, extending the service life of the tool.
Anti-adhesion: The niobium nitride coating has a smooth surface, low surface roughness and chemical inertness, which can prevent welding and adhesion during the cutting process and reduce the friction and wear of the tool.
Niobium nitride coated carbide inserts are commonly used in high-speed cutting, dry cutting, drilling, milling and other applications. They are suitable for processing steel, cast iron, stainless steel, high-temperature alloys and other materials, providing higher cutting efficiency, workpiece surface quality and Tool life.
