Cermet Inserts have good effect

As a cutting tool, the advantage of Cermet Inserts is that its material and working piece material affinity and friction coefficient is very low, so it is not easy to produce sticky inserts and chip tumor, so that the processing surface is very smooth and smooth, so that it becomes a new choice of finishing tool material. Because of its excellent comprehensive properties such as high hardness, high hardness, wear resistance, high temperature resistance, oxidation resistance and chemical stability, cermet inserts has a good effect on the cutting and machining of specific difficult working piece.

The Applications of Cermet Inserts:

Cermet is one of the tool materials mainly used in high - speed finishing and semi - finishing. Cermet inserts is suitable for cutting all kinds of cast iron (gray cast iron, ductile cast iron, malleable cast iron, cold cast iron, high alloy wear resistant cast iron) and steel (carbon structural steel, alloy structural steel, high strength steel, high manganese steel, quenched steel, etc.), can also be used to cut copper alloy, graphite, engineering plastics and composite materials.

Cermet inserts are not suitable for cutting under low speed and impact load because of their low flexural strength and poor impact toughness.

The characteristics of cermet inserts are summarized as follows:

(1) low density, hardness and thermal rigidity are higher than WC based carbide.

(2) Strong wear resistance and crescent depression resistance.

(3) Good chemical stability and oxidation resistance.

(4) The affinity with the workpiece material is small, the friction coefficient of steel is small, and it is not easy to produce sticky knife and chip tumor phenomenon.

(5) The coefficient of thermal expansion is higher than that of WC based carbide.
