The invention relates to a method for producing and deburring toothings on work pieces (6), comprising two workpiece spindles (3, 3), comprising a hobbing tool (12) and comprising a deburring device (10), wherein the workpieces (6) are automatically clamped into the workpiece spindles (3, 3), wherein the workpieces (6) are toothed with the hobbing tool (12) and then deburred, comprising the following method steps: a. receiving an unmachined workpiece (6) in a first loading position (19) via a first workpiece spindle (3) and transporting the workpiece (6) to the hobbing tool (12); b. carrying out a mill cut; c. placing down the workpiece (6) in the first loading position (19) and receiving a further unmachined workpiece (6); d. transporting the workpiece (6) machined with the mill cut to the second loading position (19); e. receiving the workpiece (6) in the second loading position (19) via the second workpiece spindle (3) and transporting the workpiece (6) to the deburring tool (10); f. deburring of the workpiece (6), wherein an intermediate storage (14) for at least one workpiece (6) is provided between the first loading position (19) and the second loading position (19), wherein the workpiece (6) is moved from the intermediate storage (14) into the loading position (19), and wherein the method steps e. and f. are carried out in the same time interval in which the method step b. also takes place.

The invention concerns a method of machining a workpiece, wherein an end-facing tooth edge of a gear profile of the workpiece that was generated by a chip-removing machining process is reworked at a first location into a chamfered edge by way of a plastic forming operation. The material which in the plastic forming operation was displaced towards the end surface of the gear profile is pushed outward as a material protrusion in the end surface of the tooth, while the material displaced towards the flank of the tooth is pushed outward as a material protrusion on the flank side of the chamfer, and the resulting material protrusions in the end surface and on the flank side are removed. The workpiece, while still carrying the material protrusion on the end surface of the gear profile, is transferred to a second location where the protrusion on the flank side of the chamfer is removed.

The invention concerns a method to generate and/or machine gear teeth on a workpiece, wherein the workpiece is subjected to a movement from a first location where the workpiece, while being held by a clamping device connected to a workpiece spindle, is brought into machining engagement with a first tool, to a second location where the work piece, while remaining in its clamped condition, is brought into machining engagement with a second tool, wherein prior to performing the movement, the connection between the clamping device and the workpiece spindle is released, and after the movement, the clamping device is connected to another workpiece spindle for the machining engagement with the second tool.
