ABSTRACT:
A hard bearing cradle balancing machine involving novel elements for workpiece support and end thrust restraint, angle of unbalance indication and machine mounted drill press slide. "V" block bearings incorporating independently tilting pads provide uniform journal contact without torsional restraint that would otherwise result from workpiece misalignment. A device magnetically attached to the end of the workpiece maintains axial positioning thereof and communicates rotational position and speed information to an electronic vibration analyzer, as well as rotational reference information to the machine operator. A balancer mounted drill press slide freely traverses the workpiece axis, locking up only upon application of drilling pressure at any point thereon.
