makes it easy to machine materials which are hard to be machined

New nano coating grade

• Special coating techniques make inserts smooth, which leads to low friction and unobstructed chip flow.
• Unique coating with nano structure closely integrates with substrate, ensuring higher hardness and toughness.
• Excellent thermal stability and chemical stability can effectively protect cutting edge.

Case

Cermet & Coated Cermet

The chemical stability between Ti(CN) base cermet inserts and workpieces is relatively high, which reduces the friction and temperature of the cutting edge during cutting, preventing mutual diffusion of atoms of the workpiece material and the inserts, and improving resistance to bonding abrasion. Therefore, Ti(CN) base cermet shows good capability of Red Hardness and resistance to crater wear. It is an optimal material for high-speed finishing and semi-finishing of steel. High temperature strength of cermet is higher than that of WC-Co, and toughness better than that of Al2O3 and Si3N4 ceramic. This fulfils the application blank of WCbase cemented carbide and Al2O3 and Si3N4 ceramic from finishing to semi-finishing at high speed.
