Efficient hard-part turning: CB7015 from Sandvik Coromant enables significant savings in transmission production

Transmissions are typically mass produced, so component costs are a vital factor for success. With its CB7015 indexable insert, Sandvik Coromant offers a cost efficient time-saving tool for hard-part turning. The tool covers a wide range of applications and delivers optimal finish quality – while being highly suited for dry machining.

Sandvik Coromant is a global leading supplier of cutting tools, tooling solutions and know-how to the metalworking industry. Its CB7015 is a CBN grade for a broad range of applications and delivers optimal finish quality in the production of transmission components. CB7015 is especially suited for turning case-hardened steels (58-65 HRc). Thanks to the innovative Safe-Lock™ clamping system, the CBN grade with a wear resistant ceramic binder is also ideal 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 consistently 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. Dry machining avoids the costs for coolant use, offers reduced capital investment and low-cost chip disposal, all of which help to further reduce machining costs.
