Cermets improve steel machining
performance
Developed to provide exceptional wear resistance and improved adhesion resistance for general steel machining operations, two Cermet insert grades raise cutting speeds.
For high performance machining of steel, NTK has now launched two Cermet grades that are siad to 'break the barriers' of conventional steel machining The C7X and C7Z provide exceptional wear resistance and improved adhesion resistance for general steel machining operations

Ceramic inserts high speed machine Inconel
Ceramic cutting tool inserts has been introduced for machining 'exotic' alloys such as the high speed machining of Inconel 718 providing exceptional reductions in machining cycle time.
The PVD TiN coated Cermet C7Z insert is particularly resistant to built up edges as its coating promotes the smooth flow of swarf away from the cutting edge.
This gives the end user an insert with increased wear resistance and improved performance that enables the C7Z to maintain its component dimensions for longer periods of machining with reduced machining offsets.
Both the C7X and C7Z Cermet grades promote excellent surface finish, extended tool life and outstanding swarf control - all whilst machining at significantly higher cutting speeds than carbide cutting tools.
The new inserts provide stable cutting performance for semi and finish machining applications regardless of running wet or dry machining.
This stability is provided by alloy binders that deliver excellent wear and thermal shock resistance and fracture toughness.
These attributes provide the end user with inserts that are capable of performing limited roughing applications through to finish machining as well as interrupted cutting.
This wide range of machining applications is provided by the thermal shock resistance that reduces chipping and tool breakages considerably.
This combination gives the end user extended tool life and thus superior confidence in cutting tool performance.
The C7Z and C7X are ideal for semi finish and finish machining of steel and bearing materials with the vast range of inserts making the new grades applicable for grooving and turning applications.
The new grades are available with 80, 55 and 35 degree rhombic positive type insert with 0.1, 0.2 and 0.4mm radius to meet the end users numerous turning requirements.
