When your manufacturing tolerances are tight and the surface finish requirements are strict, standard tungsten carbide tools may struggle to deliver optimal results during high-speed finishing passes. For these demanding applications, Cermet cutting tools—specifically Titanium Carbonitride (TiCN) based hard alloys—are the ultimate solution for precision CNC turning and milling.
What Makes TiCN-Based Cermet Superior?
Unlike traditional tungsten carbide tools that use Cobalt as a binder, our Cermet inserts are primarily composed of Titanium Carbonitride [TiC(N)], utilizing Molybdenum (Mo) and Nickel (Ni) as the metallic binder phase. This unique metallurgical composition grants Cermet tools extraordinary physical and thermal properties.
According to material performance metrics—and supported by advanced materials research published via ScienceDirect—TiCN-based alloys exhibit a soaring heat resistance of 1100°C (compared to standard carbide’s 800°C) and an elevated hardness of 92 to 93.5 HRA.
Chemical Stability: The Secret to a Mirror Finish
The true advantage of our TiCN based carbide tools lies in their chemical property matching. When machining steel and cast iron, chemical affinity between the tool and the workpiece causes material adhesion, leading to a Built-Up Edge (BUE) that ruins surface finishes.
Our Cermet tools feature:
- Exceptional Anti-Adhesion: A remarkably low friction coefficient and low chemical affinity with ferrous metals prevent sticking, ensuring a pristine CNC surface finish.
- High-Speed Capability: Because they maintain their hardness and resist oxidation at extremely high temperatures, our Cermet inserts are engineered for high-speed, continuous precision finishing.
- Low Thermal Expansion: With a lower thermal expansion coefficient than standard carbide, Cermet tools undergo minimal dimensional changes during cutting, which is vital for maintaining strict dimensional accuracy in ultra-precision machining.
Ideal Applications for Cermet Tooling
Based on comprehensive machinability data, our Cermet tools are rated as “Excellent” for machining Cast Iron and “Good” for Pure Steels and Hardened Steels. While they are not recommended for titanium alloys or high-silicon aluminum, they are absolutely unmatched when utilized for the final finishing passes on ferrous automotive and aerospace components.
