CARBIDE (PVD, CVD)

CARBIDE (PVD, CVD)

Excellence in precision machining and machining of hard-to-cut materials

These material grades use WC micro-grain carbide, the hard layer of which is granulated to a micro size 1µm as the substrate. Furthermore, the substrate is coated by the PVD method with TiN, TiCN, and/or TiAlN. The end results are materials that are suitable for precision machining and machining of difficult-to-cut materials. Inserts in these grades are tougher and harder than carbide and come with precision sharp cutting edges. They even have superior toughness and sharper cutting edges than ultra micro-grain carbide grades, with excellent wear resistance and thermal crack resistance.

CERMET (TiC, TiN)

CERMET (TiC, TiN)

CERMET is a cutting tool material composed mainly of TiC (Titanium Carbide) and TiN (Titanium Nitride). The name CERMET is derived from the words ceramic and metal (representing carbide).
As the name suggests, cutting performance is also in the mid-range of ceramic's and carbide's. The advantages of this material grade are high-quality and excellent surface finishes that can be achieved with elevated cutting speeds. CERMET provide extended tool life since it is less reactive with work materials. Also available, PVD coated CERMET graded that improve wear resistanceof the titanium since it does not contains any binder components.

NTK's premium ceramic grades ensure the user higher productivity. All of the grades show superior high temperature hardness, heat resistance and chemical stability. NTK offers many types of ceramic cutting tool materials (silicon nitride-based, alumina-based and whisker-based) in a variety of geometries to meet customer demands.

- Alumina-based ceramics (White ceramics) / ForGray Cast Iron
- Alumina TiC-based ceramics (Black ceramics) / ForGray Cast Iron, Ductile Cast Iron, Hardened Materials, Mill Rolls
- Whisker-reinforced ceramics / ForHeat Resistant Alloys, Gray Cast Iron, Hardened Materials, Mill Rolls
- Silicon nitride-based ceramics / For Gray Cast Iron, Ductile Cast Iron, Heat Resistant Alloys

Some of the advantages of ceramics are: high hardness at high temps giving excellent wear resistance at high speeds, and allowing low impact in relation to bending strength allowing stable machining at high speeds.
