METHOD AND APPARATUS FOR VIBRATION CLEANING OF WORKPIECES SUCH AS ENGINE BLOCKS Abstract of the Disclosure A method and means are disclosed for vibration cleaning of casting and manufacturing debris from engine blocks and similar articles. The method involves resonant torsional vibration of the workpiece around a longitudinal axis, preferably in the first torsional vibration mode. The workpiece may also be rotated at the same time to permit loosened debris to fall from the walls and cavities. A vibration cleaning stand is also disclosed including a rotatable frame with resilient supports, for holding and rotating an engine block, together with a small eccentric shaker, which is secured to the main bearing caps at one end of the block and rotated by a motor to resonantly vibrate the block in its first torsional mode of vibration.
