Sandvik CoroMill 177 tangentially-mounted hob permits aggressive cutting data
The Sandvik Coromant CoroMill177 tangentially-mounted hob for gear wheel machining features a segment fixturing interface for cutter accuracy and rigidity during machining. The stability allows more aggressive cutting data without risk to process security or reliability.
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. Sandvik Coromant recommends it as a good alternative to HSS hobs and disc cutters in operations where productivity is the focus.
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.
