Carbide is the allrounder among cutting materials. Its properties can be perfectly customised and, with the right coating, the generalist becomes a specialist with unique capabilities.
The same old favourites can always be found in carbide cutting tools: Tungsten carbide and cobalt. Nevertheless, the indexable inserts can be completely different in terms of toughness, wear or temperature behaviour. The reason: These characteristics are defined by the composition and grain size. Variety is therefore guaranteed with carbide.
The coating also has an enormous influence on performance and the range of applications. This is why most of our carbide indexable inserts are coated. No matter what you have in mind: The performance is impressive.
Stable against crater wear: CVD coatings
Stable against crater wear: CVD coatings
In the CVD process (chemical vapour deposition), a chemical reaction occurs between the coating material and the carbide surface at temperatures of 700 °C and above. This results in very hard coatings. Above all, they reduce crater wear and increase hardness.
Extremely hard and wear-resistant: PVD coatings
Extremely hard and wear-resistant: PVD coatings
The PVD process (physical vapour deposition) converts the coating material into the gas phase in a vacuum. By adding nitrogen, for example, nitride compounds such as the extremely hard and temperature-resistant titanium aluminium nitride can be formed. This then forms a firmly adhering layer.
Ideal for long-chipping materials, thin-walled components and optimal surface qualities – high-positive indexable inserts with sharp edge executions from ARNO.
Ideal for fine machining of high-temperature materials and stainless steels: high-positive indexable inserts with edge-honed executions from ARNO.
