Seco Tools’ latest cubic boron nitride (CBN) grades CBN010 and Secomax CBN060K are for turning hardened steels and other hard materials.

CBN010 is an uncoated grade designed to excel in continuous to moderately interrupted cuts. Offering an extremely homogenous structure, the grade provides stable performance and consistent tool life to minimize downtime and machining costs.

Featuring low CBN content with an average grain size of 1.5 microns and a TiC ceramic binder, CBN010 is produced using a manufacturing process that achieves a highly uniform microstructure. This improves both wear resistance and toughness, allowing excellent performance in a range of materials, the company says.

Optimized for case hardened steels and bearing steels, CBN010 can also be successfully applied to tool steels, high speed steels, high tensile steels, martensitic stainless steels, ferrous powder materials and hard facing alloys. Inserts are available in solid, full face, tipped and multi-tipped formats.

Secomax CBN060K is the result of extensive development and combines multiple new manufacturing technologies to improve productivity and tool life in the high-feed turning of case-hardened steels. It incorporates a multi-layer PVD coating with improved adhesion and reduced coefficient of friction, increasing wear resistance and edge security. The grade’s carefully tailored substrate material consists of micron-sized CBN particles in the first superalloy binder with a TiCN hard phase, the company says. Unique CBN particle distribution increases tool life and consistency, while providing excellent workpiece surface finish.
