ABSTRACT:
A machined or cast part is rigidly attached to the interior of a container having an open top, closed side walls and a bottom with a restricted opening near or at the bottom of the container and abrasive cleaning and deburring material is inserted into the container through the top and the container is vibrated. A relatively small amount of the cleaning media is allowed to leave the container through the bottom opening and is replaced by adding abrasive material through the top and the vibrations cause the material to churn in the container upward around the part and into and through recesses and openings in the part.
