Steel turning tools include CVD coating, carbide substrate, chipbreakers

Kyocera has released the CA115P/CA125P CVD-coated carbide for machining steel. This offering combines a coating, carbide substrate, and chipbreakers.

According to the company, the new tools extend tool life in numerous machining scenarios. For example, the CA115P is suitable for continuous to light-interrupted machining. Conversely, the CA125P is optimized for continuous to heavy-interrupted machining.

The coating properties on the rake and flank faces provide good wear resistance, the manufacturer states. The black and gold appearance and stark contrast of the tools are more than just cosmetic in nature. The black rake face is composed of a highly uniform alumina layer, which reduces wear, suppresses cratering, and reduces fracturing, the company states. The gold flank includes a hard surface layer, a highly uniform alumina layer, and a titanium carbonitride (TiCN) layer. These layers on the flank work together to improve the wear-resistant properties of the insert and to suppress surface abrasion. Below the coating, the new carbide substrate displays enhanced resistance to plastic deformation and exhibits increased temperature resistance, the manufacturer states.

Chipbreaker options cover finishing to roughing and the company is introducing the PMG chipbreaker for medium to roughing when machining steel.

There are many positive and negative rake options and multiple cutting edges per insert.

While suitable for machining steel in continuous to heavy-interrupted applications with options for finishing and roughing, these tools also can be used for external and internal turning, facing, and boring.
