A first set of teeth (3) are machined initially, then the work tool (13) is oriented into the chosen position for the second set of teeth (2) for further machining. Orientation of the tool is carried out without losing the synchronisation between the workpiece and machine tool rotation, by altering the angular position of the tool relative to the workpiece, and by altering the spatial position of the tool relative to the workpiece in relation to the NC-machine x, y and z-axes. An independent claim is also included for the device used to carry out this method in an NC-type toothed wheel roller grinding or milling machine, comprising a spindle (11) with a clamping device (10) for the workpiece, and a tool head movable relative to the workpiece about the NC-machine x, y and z-axes, the tool head comprising a spindle with a worm clamped onto it, the rotary movement of the workpiece and worm being synchronised. |
