The CB7015 from Sandvik Coromant enables improved hard-part turning.

Sandvik Coromant has introduced the CB7015 indexable insert tool for the production of transmission components. According to the company, the cubic boron nitride (CBN) ?tool covers a wide range of applications and delivers improved finish quality while being highly suited for dry machining.

The CB7015 is especially suited for turning case-hardened steels (58-65 HRc) and the CBN grade with a wear resistant ceramic binder is also suitable for dry machining. It complies with all standard shape and position tolerances. 

The CBN product range from Sandvik Coromant includes inserts with standard corner radii and wiper inserts as well as an Xcel version. The patented wiper geometry offers a range of process optimizations including improved finishes for standard cutting data. It also provides higher finish quality with significantly increased feeds – roughness grades far below 3.2 µm can be achieved. With Xcel geometries and feeds of 0.3 mm, even roughness grades of 1 µm are possible. In addition, the Xcel insert, with up to 8 cutting edges, enables shorter production times and extremely reduced tool costs per component.
