- the inventive method for grinding machining of a machine component takes place in one and the same clamping.
- the machine component is preferably a gear shaft or a gear.
- the machine component is tensioned at its two axial ends with respect to the longitudinal axis of the machine component and has an inner recess at least at one end.
- the inner recess is ground by means of an inner grinding wheel, which is preferably also referred to as fnnenschleifjan.
- the machine component is see a Maschinen Scientificspi ndelstock and a tailstock driven to rotate, wherein by means of at least one grinding wheel, the outer contour of the machine component is ground.
- the machine component is therefore kept centered on the one side by means of the workpiece spindle nose and on the side opposite the tailstock with a tailstock hollow spindle on the end region of the inner recess pointing outwards towards the end of the machine component.
- the tailstock hollow quill makes it possible for the inner grinding wheel to be penetrated during the grinding of the inner recess. Since the tailstock hollow quill preferably engages with a running hollow point in the inner recess of the machine component and the machine component is also centered on the opposite side in the workpiece headstock, the machine component can in a single clamping both outside and inside and possibly also to his front sides are sanded.
- a tailstock hollow quill with hollow point or on the workpiece headstock a hollow point or - if the machine component has an inner recess at each of its ends - a tailstock hollow quill with hollow point as well as a workpiece spindle hollow quill are provided with hollow point, which can be penetrated by the respective inner grinding wheel, it is preferably possible that the outer grinding and the inner grinding at least temporarily performed zeitparailel the. This additionally has a cost-saving effect because it reduces the cycle time during the production of the machine component.
- Vorzugswesse is maintained during grinding the reference axis for the machine component, ie its rotation longitudinal axis unchanged, because this coincides with the taking place at both ends of the machine component centering. Especially with parts of normal length and normal stiffness, a steady support is not required.

This ensures that the sharpening of the outer contour of the machine component and the inner surface of the inner recess can be performed at least temporarily parallel to time.
- the rotational axis of the grinding wheel for the outer grinding and the common axis of rotation of the workpiece headstock, machine component and tailstock obliquely arranged in space to each other such that during grinding substantially only a point contact between the grinding wheel and the outer contour of the machine component is present.
