SCBN400C encompasses the latest synthesis technological developments in its manufacture, which together with a fine closely controlled grain size, gives optimum product homogeneity.
The result is a PCBN grade for grey cast iron machining which offers long, consistent and predictive tool life, outstanding machined surface finishes and superb machined dimensional accuracies.
When used to finish machine grey cast iron, CBN400C has shown to give significant improvements in achieving and maintaining strict surface finish, dimensional and tool life requirements.
To get the best out of PCBN tooling
When machining grey cast iron components, use CBN300 for roughing operations and CBN400C for finishing operations.
CBN400C has a grain size of 3-6 microns and a CBN content of 90% and is available in a range of insert styles commonly used in the machining of grey cast iron components.
Coated PCBN visibly improves tool life
The lifetime of a CBN400C cutting tool is increased many times due to the much higher hardness, in combination with optimised pretreatments and deposition conditions, of the unique (Ti, Si)N coating compared to traditional (Ti, Al)N coatings.
In addition to the performance benefits of the (Ti,Si)N coating, the copper colour provides clear detection of worn edges.
Both contribute to the reliability and confidence in cutting tool performance.
