A method for hard fine machining of the toothing of a gear that has an axis of rotation, wherein the toothing is machined with a hard fine machining tool. The machining tool rotates around an axis of rotation during hard fine machining. The method includes: a) Providing a hard fine machining tool that has axially adjacent machining zones, including a first zone for the grinding the toothing and a second zone for fine grinding and/or polishing the toothing; b) Grinding the toothing with the first zone, wherein a first pivoting angle exists between the axis of rotation of the gear and the axis of rotation of the machining tool; c) Fine grinding and/or polishing the toothing with the second zone of the machining tool, wherein a second pivoting angle exists, which is different from the first pivoting angle, between the axis of rotation of the gear and the axis of rotation of the machining tool.

A method for the grinding finish machining of an already toothed gearwheel workpiece in an NC-controlled machine tool, comprising the following steps: a. providing the gearwheel workpiece in the machine tool, b. providing a first grinding tool in the machine tool, c. providing a second grinding tool in the machine tool, d. grinding machining of at least one tooth flank of the gearwheel workpiece using the first grinding tool, e. grinding machining of at least one tooth flank in the transition region to the tooth head of the gearwheel workpiece using the second grinding tool in the machine tool to generate a head edge rounding on the gearwheel workpiece, f. further grinding machining of at least one tooth flank of the gearwheel workpiece using the first grinding tool and/or the second grinding tool in the machine tool.

A method for hard finishing two different toothings on a workpiece, wherein, prior to each machining process, to set the correct tool engagement position for the machining process, a first relative rotational angle position of a first rotational position reference of the first toothing is determined relative to an axial rotational position of the workpiece spindle holding and clamping the workpiece for the first machining, and a second relative rotational angle position of a second rotational position reference of the second toothing is determined relative to an axial rotational position of a workpiece spindle holding and clamping the workpiece for the second machining, wherein the machining operations are carried out on the same workpiece spindle with no intervening clamping change, and with the first and second rotational position references coupled to each other as the basis thereof.

A method for the manufacture of a gear component includes, in a soft machining process, introducing a preliminary toothing 3 with a machining allowance 7 that is fixed relative to a final toothing 4 into a blank such that a semi-finished part 2 is produced. The method also includes, in a fine machining process, removing the machining allowance 7 and producing the final toothing 4 of the toothed component. The machining allowance 7 is removed in a single-stage hobbing method by a grinding tool 1, wherein the grinding tool 1 removes the machining allowance completely in a single stroke movement H.
