ABSTRACT:
An apparatus is disclosed which enables a controlled member (e.g. a workpiece retaining member in a jig) to be adjusted in position by extremely small amounts of linear displacement or angular rotation, with a very high degree of accuracy and static and dynamic stability. The apparatus is based on a servo system controlled by electrical signals and employs hydrostatic pads to support and move the controlled member.
