ABSTRACT:
An automatic true centering steady rest apparatus for a rotating cylindrical workpiece during a machining or grinding operation on the workpiece. The apparatus has an integrally mounted gaging device, for continuously gaging the diameter of a workpiece during a machining or grinding operation. A pair of gripper arms are slidably mounted on an operator body in a housing. Each gripper arm and the operator body carries a workpiece contact member engageable with the perimeter of the workpiece. The gripper arms are urged to grip a workpiece by the action of a pair of rollers and two sets of fixed guide pins which are operatively engageable with camming contours contained on opposing inner surfaces of the apparatus housing. The improved efficiency of the apparatus, as a result of the roller and guide pin action allows for placing the gaging device remotely from the workpiece, without any loss in the precision of its measurement.
