cermet
Cermets are cutting tools made by pressing or injection molding metal powder and then sintering cemented carbide powder with titanium carbonitride. is a carbide milling cutter, but the difference is that it contains titanium carbide nitride (titanium carbide, TiC and titanium nitride, TiN), which improves wear resistance and resistance to cladding.
The manufacturing of cermet tools incorporates the precision process of powder metallurgy, which shapes the basic shape of the tool by pressing or injection molding the metal powder, and then sintering the cemented carbide powder containing titanium carbonitride at high temperature. This process precisely controls the density and microstructure of the material, laying a solid foundation for tool performance. The pressing process is suitable for creating tools with simple shapes, while injection molding enables precise reproduction of complex blade profiles, catering to diverse machining needs.
As a special member of the carbide knife family, cermet knives are unique in their composition. It uses titanium carbinitride as its core component and contains two key compounds, titanium carbide (TiC) and titanium nitride (TiN), which distinguishes it significantly from traditional cemented carbide. This unique composition provides a double performance improvement: titanium carbide gives the tool extreme hardness and wear resistance, keeping the edge sharp at high speeds; Titanium nitride optimizes the chemical stability of the material and reduces chemical reactions during cutting.
Excellent wear resistance makes cermet tools perform well under continuous cutting conditions, and their service life far exceeds that of ordinary high-speed steel tools. The enhanced cladding resistance is its core advantage, which can effectively reduce the bonding phenomenon of workpiece materials at the cutting edge during the cutting process, avoid the formation of accumulated edges, and ensure the stability of the machining surface quality.
In practical applications, cermet tools are particularly suitable for semi-finishing and finishing of difficult-to-machine materials such as high-strength alloys and hardened steels. Its good red hardness allows working at higher cutting speeds, increasing productivity while achieving ideal surface roughness. This combination of hardness and toughness makes cermet tools an important choice in modern precision machining, playing a key role in industries such as automotive manufacturing and mold processing.
