Anti-rust, Anti-corrosion, Durability better
◆ Coating adhesion strong, enhance hardness, and anti-rust better in different surroundings, such as acid, alkali, ammonia, salt etc.
◆ Overall nickel coating, including inside and outside cone, even if you do not take any anti-rust actions, it will not rust either,
don't influence processing precision and spindle.
◆ Improve cleanness, precision more stable, surface more smooth, feel more comfortable and appearance nicer.

Cryogenic treatment
◆ -384.8℉ long cryogenic, nearly all of the residual austenite into martensite.
◆ Carbide precipitation of nanoscale particles, increasing the hardness and toughness.
◆ Reducing residual stresses.
◆ Wear resistance significantly improved.
Thermal aging processing
◆ long stereotyped thermal limitation removal of grinding residual stress.
