Abstract
The present disclosure relates to a method and to an apparatus for chamfering and deburring gear cut workpieces, especially of large-volume gear cut workpieces, using a deburring apparatus which is arranged on or at the cutting head of a gear cutting machine and which at least partially utilizes the machine axes of the gear cutting machine to chamfer and to deburr gear teeth along a tooth contour.
Claims15
A method for chamfering and deburring a gear cut workpiece comprising:
- arranging a chamfering and deburring apparatus on or at a cutting head of a gear cutting machine;
- and
- cutting a chamfer by pivoting a chamfering spindle of the apparatus with a chamfering miller from a rest position outside a disturbing contour of the gear cutting machine into a work position in a working region of a gear cutting tool at the chamfering and deburring apparatus, wherein, the chamfering spindle is positioned with the chamfering miller closer to the workpiece than the gear cutting miller so that the gear cutting tool can remain in a cutting head of a chamfer cutting;
- wherein movements of the chamfering spindle with a chamfering cutter for a contour tracking along the tooth edge take place by movement of axes of the gear cutting machine.
1 more element
A chamfering and deburring apparatus, comprising:
- a chamfering spindle;
- a chamfering miller;
- a drive motor;
- and
- a control system with computer readable instructions stored on non-transitory memory for:
- after the chamfering and deburring apparatus has been arranged on or at a cutting head of a gear cutting machine;
- cutting a chamfer by pivoting the chamfering spindle with the chamfering miller from a rest position outside a disturbing contour of the gear cutting machine into a work position in a working region of a gear cutting tool, wherein the chamfering spindle is positioned with the chamfering miller closer to a workpiece than a gear cutting miller so that the gear cutting tool can remain in a cutting head of a chamfer cutting;
- and
- moving the chamfering spindle to track a contour of a gear tooth edge via movement of axes of the gear cutting machine.
6 more elements
A method, comprising:
- guiding a chamfering tool along a tooth edge of a gear tooth via axial movements of a cutting head while rotating a workpiece at a predefined speed about a center axis of the workpiece.
