Insert grades for optimizing steel turning

With common steel turning operations in mind, CERATIZIT introduced three new standard coated-carbide ISO-P steel insert grades providing up to 20% longer tool life when compared to previous generation grades. The new inserts are highly engineered for increased productivity and feature advanced substrates, geometries and CERATIZIT’s innovative Dragonskin multi-layer coating for lower heat and less tool wear. 

To prevent insert waste and easily detect wear, the gold-colored TiN outer layer of the Dragonskin multilayer CVD Ti(C,N)/Al2O3/TiN coating acts as an indicator. It enables users to clearly identify insert wear and index before a breakage and prevents sharp cutting edges from going unused and the insert being inadvertently discarded. Plus, a mechanical post-coating treatment produces beneficial residual stress in the coating that results in increased process security, especially important in the large-volume production situations typically associated with turning ISO-P steels. 

Each of the three grades are engineered for optimizing specific production scenarios. The CTCP115-P (ISO P15) grade has enhanced resistance to high temperatures and is ideal for use at higher cutting speeds in smooth, continuous cuts in stable cutting conditions. The CTCP125-P (ISO P25) universal steel-cutting grade balances toughness and wear resistance to provide consistent reliability in turning operations ranging from finishing to rough machining, while the CTC135-P (ISO P35) is a tough carbide grade for lower cutting speeds, interrupted cuts, and unstable machining conditions.

A new UP2Date product brochure from CERATIZIT provides additional details about the new grades and information about a variety of other productivity-boosting metal cutting tooling and accessories.
