The invention relates to a method for creating or machining gears on workpieces (W1, W2), in which a rolling first machining engagement between a machining tool (WF; WS) that is driven about its rotation axis (B) and a first workpiece that is rotatable about the rotation axis (C1) of a first workpiece-side spindle (11) is realized at a first location on a gear-cutting machine (100; 200) by means of a tool-side spindle drive motor (22), and in which a second machining engagement is realized at a second workpiece, different from the first workpiece, that is rotatable about the rotation axis of a second workpiece-side spindle (12) that is different from the first workpiece-side spindle, wherein the machining tool can execute, relative to the first workpiece-side spindle, a movement, serving as an axial infeed movement in the first machining engagement, along a tool-side machine axis (Z) that has a direction component in the direction of the first workpiece-side spindle axis and in particular extends parallel thereto, wherein, after the first machining engagement, a tool-side positioning movement that takes place along this tool-side machine axis and allows the second machining engagement is carried out, wherein the second machining engagement is a machining engagement that is identical to the first machining engagement in terms of type of machining, is effected using the same tool-side spindle drive motor as in the first machining, and is carried out in the gear-cutting machine at a second point that is different from the first point.

A method of generating machining of a gear-shaped workpiece (23), in particular by continuous generating grinding, in which the gear-shaped workpiece rotates about a workpiece axis (C) while in generating mesh with a generating machining tool. During machining, the gear-shaped workpiece performs an oscillating movement which is superimposed on the rotation of the gear-shaped workpiece. Also disclosed are a clamping device (22) configured to perform the method, and a system comprising such a clamping device and a control device (50). Finally, a generating machining machine comprising a clamping device of the mentioned type is also disclosed.

Process of grinding and polishing flank surfaces of teeth of toothed wheels, which includes a grinding device, a polishing device, a dynamic positioning device, and a toothed wheel.
