a combination spindle-drive is provided for fabrication of optical quality surface finishes. both the spindle-and-drive utilize the spindle bearings for support, thereby removing the conventional drive-means bearings as a source of vibration. an airbearing spindle is modified to carry at the drive end a highly conductive cup-shaped rotor which is aligned with a stationary stator to produce torque in the cup-shaped rotor through the reaction of eddy currents induced in the rotor. this arrangement eliminates magnetic attraction forces and all force is in the form of torque on the cup-shaped rotor.
