CERMET inserts for machining technology
Cermets are a type of cutting material composed of ceramic elements in a metal matrix and are noted for their impressive hardness and resistance to wear.
In machining, cermets are proving to be ideal for all types of
processing tasks where precise surface finish, dimensional accuracy and
tight tolerances are required. They offer a long service life with low
to medium chip volumes and constant oversizes.
In these application areas, they are used for turning, grooving and milling processes. Metav provides an extensive range of chipbreaker geometries for indexable inserts to ensure optimal chip formation. These geometries are designed in such a way that they provide reliable chip breaking and a chip shape suitable for automation in their respective area of application.
Cermet cutting materials are characterized by their use in areas with high demands on surface quality, dimensional accuracy and tight tolerances. They offer considerable durability with low to medium tool loads. Aside from steel, they are particularly well suited for fine and coarse finishing of sintered metals, ductile cast iron and stainless steel. ISCAR will be presenting a variety of negative and positive insert geometries, including wiper variants. Even during pre-finishing, the cutting edges create excellent surface finishes.
The Cermet product line offers an extensive range of chipbreakers with polished surfaces to ensure reliable chip breaking in automated machining processes. This avoids problems caused by metal slugs that could block the machine room or damage the component.
During the manufacturing process of cermets, the ceramic material is either impregnated with liquid metal or sintered together with the corresponding metal in the solid state. The sintering process is similar to that of homogeneous powders, but the metal is compressed more than the ceramic with the same pressing force.
