NX3035 - Tough new cermet grade

The latest generation of cermet inserts for steel turning now provides cutting edge stability even when using coolant, an area where the use of conventional cermet grades resulted in unpredictable tool life.

A large range of over 300 inserts, with negative and positive geometries are available and the series also includes a varied range of chip breakers to suit all applications.

Cermet is a composite material made of hard particles such as titanium carbo-nitride (TiCN) based ceramics and a metal binder such as Ni.

NX3035 uses a special alloy binder that offers even higher thermal conductivity and bonding strength, and as a result it delivers much improved thermal shock resistance. This reduces thermal cracking and enables NX3035 to exhibit a high degree of tool life stability even during wet machining, an area where conventional cermet lacks performance. Tests have shown that thermal shock resistance was doubled compared to other cermet grades.

The use of coolant during high speed finishing helps to maintain excellent surface finishes and additionally, dimensional accuracy of components can be maintained for longer due to the stability of the cutting edge.
