Nachi GS MILL Hard Carbide End Mills

Manufacturer: Nachi-fujikoshi corp
Model: GS MILL

Outline

Super high speed milling
Newly developed ultra aluminum rich Al-Ti-Cr multi-layered “GS
Hard Coat” allows super high speed milling up to 800m/min.
Unique geometry improves chip removal and tool rigidity.
Improved durability due to new ultrafine particle. cemented carbide.
Long tool life
Ultra micro grain low-cobalt carbide with high hardness improves tool material strength and curtails micro-plastic deformation that can occur at very high speeds. The result is better durability.

Features and Performance

GS Hard Coat

Top layered film consists of newly developed ultra aluminum rich Al-Ti-Cr coating. with 3 times better oxidation resistance at 1.100 deg Centigrade.

Improved heat and wear resistance at ultra high-speed milling
AlCrTi oxidation prevention layer
Microstructure provides higher film strength
Ti-Al wear resistance layer
High-strength Carbide material
Fewer macroparticles on film surface result in improved smoothness
Reduced abrasion and better deposition resistance
Improved wear and adhesion resistance

GS Hard Coating
Conventional coating
New geometry
Smoothly curved flute geometry improves chip removal.
Wide land improves tool regidity
