| | | ■ An unremoved burr may break off during machining and lead to damage of bearings or gears in gearboxes. ■ Over-carbonizing may also result in too much pressure being exerted on the sharp gear lateral surfaces and therefore in potential breakage. ■ A hardened burr may, in the event of a subsequent finishing operation, lead to premature wear of the tool. Removing the burr, however, prolongs the life of the finishing tool significantly. | | |
