EVERSHARP’s Surface Enhancement Coating
  • The technology that applies PVD and CVD (TiN) coatings to components.
  • Improves hardness, appearance, lubricity, and wear.
  • Extends tool life as much as five times under some conditions.
  • An excellent preventive for galling and metal pickup.
  • Minimizes machine down-time due to fewer tool changes, resulting in 5-30% longer tool life.

 

TiN
The general-purpose coating for cutting, forming, injection molding as 		TiAlN
The universal high-performance coating for cutting (drilling, milling, reaming, turning). Also suitable for dry machining.
TiCN
Conventional carbon nitride coating
  • for interrupted cutting
  • for milling and tapping
  • for stamping, punching and forming
AlTiN
Special high-performance coating:
  • very high aluminum content
  • very high heat resistance
  • for dry high speed machining
  • especially at hard machining
