<p>The invention relates to a work spindle, particularly for a machining machine tool, having a drive shaft that has a free end for driving a machining tool, two bearings, in which the drive shaft is pivot-mounted on an axis, and a drive for the drive shaft, wherein the drive shaft has a deflection of the pivot axis between the bearings whenever a radial interfering force impinges upon the free end, and has an actuator disposed between the bearings for applying a balancing force on the drive shaft operating in opposition to the deflection. According to the invention, the drive comprises a stator, which encompasses the drive shaft between the bearings at least partially for cooperating with a rotor configured on the drive shaft between the bearings, and the actuator comprises an actuator solenoid, which is disposed in the stator.</p> |
