Cermet VS Carbide

  Carbide VS Cermet

Nowadays many difficult-to-machine materials widely used, such as stainless steel of Cr and Ni content is higher, the Cr can improve the strength and toughness of stainless steel, but increase the caking tendency between stainless steel and cutting tool;Ni can have the effect of stable group, but large plastic, easy to cause work hardening, although using cobalt tungsten carbide cutting tools for processing , the processing effect is not very ideal.


TiCN based Cermets with high bending strength, superior wear resistance and stable performance by wet cutting, in the processing of stainless steel materials, working life is more than 5 times as much as tungsten carbide and with high quality surface finish.

Cermet cutting tool features:

1.High quality surface finish

The main components, TiC and TiN, have good deposition resistance as they have low affinity with work materials. Thus, machining with cermets brings high quality surface finish over extended periods of time.


2.High hardness and hot hardness.

The frictional wear behind cutter is mainly caused by the relative motion between cutter and workpiece,and directly influenced by the hardness and hot hardness of the cutter,Cermet blade is of high hardness and red hardness,therefore its back face is of good wearability and extends the service life of the cutter.


Cermet material is a new and potential cutter material which not only has toughness, high-thermal conductivity and good heat stability of metals but also has high hardness, high red hardness, corrosion resistance and wearability of ceramics. The cutting efficiency of ceramic blade is 3-9 times of that of common carbide blade, and is especially suitable for cutting high-strength material. With its unique functions on fast cutting and high-precision processing.
