CErMET

turning turning
& A matrix of TiCN with carbide as a metal binder, Union Cermets are tougher than ceramics and harder &
Milling than tungsten carbides. It shows greater wear resistance than carbide and its cutting speed is also much Milling
higher than carbide. Cermet inserts give excellent surface finish and high-speed machining.
Choice of Ceramic Grade for Workpiece
• Four different grades for different workpiece and cutting condition.
• Ideal for high-speed finishing and milling of mild steel, carbon steel and alloy steel. Machining Speed (V) Feed (f) Depth (DOC)
• Excellent performance in turning, grooving, boring, bearing and milling. Application Grade Workpiece Type (m/min) (mm/rev) (mm)
