Zusammenfassung:	A dynamic spindle adjustment permitting an adjustment movement for the compensation of a wobble of the body held by the work spindle is provided on the spindle bearing of a machine tool. The regulation is designed at least dynamically enough for the regulation to permit a reliable tracking of the rotating work spindle. As a result of this, one or more spindles can be moved relative to a stationary machine in such a manner that the path of a body held on the work spindle represents an ideal rotation about the desired body axis, that is, the axis of symmetry. The compensation motion can be achieved by energizing appropriate actuators of the bearing devices with sinusoidal and cosinusoidal adjustment signals, which are superimposed to produce a circular motion of the affected bearing device.This circular motion compensates for orbital motions of the misaligned body ( 7 ) held on the work spindle.
