Abstract
The present invention provides a hobbing machine. The hobbing machine includes a clamp fixture adapted to retain a gear blank. A motor is operatively connected to the clamp fixture and is configured to rotate the clamp fixture and the gear blank together at a predetermined speed. A rotatable cutter is translatable into engagement with the gear blank and is configured to cut the gear blank and thereby produce a plurality of gear teeth. A de-burring tool is translatable into engagement with the gear blank and is configured to remove burrs from the gear blank as the gear teeth are being cut. A motorized spindle is operatively connected to the de-burring tool, and is configured to power and rotate the de-burring tool at a predefined speed to optimize the removal of the burrs.
