Abstract
A device for finish-machining of the optically effective surfaces of, in particular, spectacle lenses has a spindle shaft, which has a tool mount section and which is mounted in a spindle housing to be rotatable about a workpiece rotational axis (A). An electric rotary drive has a rotor and a stator by which the spindle shaft operatively connected with the rotor is drivable to rotate about the tool rotational axis. An adjusting device axially displaces the tool mount section with respect to the spindle housing in the direction of the tool rotational axis (linear movement Z). The rotor and the stator are arranged coaxially with the spindle shaft, wherein at least the rotor together with the spindle shaft is axially displaceable with respect to the spindle housing in the direction of the tool rotational axis by the adjusting device.
