The CoroMill® 177 tangentially-mounted hob from Sandvik Coromant features a number of innovations designed to deliver greater productivity and tool life in gear wheel machining operations.

 

For instance, a unique new segment fixturing interface ensures cutter accuracy and rigidity to deliver greater stability during machining. The result is the ability to achieve aggressive cutting data without compromising process security or reliability.

 

Four cutting edges

Designed for module range 10-18, CoroMill 177 features indexable carbide inserts with four cutting edges for roughing, semi-finishing and finishing operations. The tool is aimed at parts that include spur gears and helical gears found in gearboxes and transmissions for wind power and other heavy industry applications. It provides a good alternative to HSS hobs and disc cutters in operations where productivity is the focus.

 

Even against other indexable insert hobs, the robust design of CoroMill 177 allows higher cutting data (up to 50% more) compared with competitor tools, while modern carbide grades from Sandvik Coromant can handle a higher chip load to deliver a minimum 30% improvement in tool life.

 

Impressive performance

In trials on a 36-tooth, module 16 planetary gear, CoroMill 177 exhibited 67% greater tool life over a comparable competitor tool at identical cutting data. Similarly, another trial on a module 18 planetary gear with 33 teeth, showed a 54% boost in productivity, primarily because the more robust design of CoroMill 177 allowed the feed rate to be increased.

 

Ultimately, the secure and stable insert seats offer a reliable performance with no sudden failures. Tools can be designed to accommodate finishing inserts for DIN 3972-2 profiles but also roughing inserts with protrusion. Insert mounting is both simple and precise – insert screws are positioned to be accessed easily and there are no inclined screw holes.
