ABSTRACT:
A machine tool assembly includes a high speed rotating spindle for forming extremely precise surface contours on a work piece. The spindle is supported on a spherical air bearing about its center of gravity. The spindle can be rotated through an air turbine drive system incorporated into the spherical air bearing to eliminate any undesirable moments about an axis perpendicular to the long spindle axis. The spindle is adjustable in pitch and yaw directions through the influence of X-Y actuators. The X-Y actuation system is preferably electromagnetic and provides a non-contact method of displacing the spindle shaft in a controlled manner at any speed.
