Abstract: A deburring and cleaning maching and process for cleaning and deburring both interior and exterior portions of articles. The process includes mounting the article to be cleaned and deburred in a mounting means and then imparting vibratory movement to an exciter member. A vibration conduction means transfers the vibrations directly to the mounting means. Abrasive media is cascaded over, around, and through the article as it is vibrated within the substantially open space in a framework. The machine utilizes a substantially open framework. A mounting means is positioned within the framework. An exciter member is operatively connected to a vibratory means. A vibration conduction means transfers vibration from the exciter plate directly to the mounting plate. A cascading means is positioned above the fixture to direction abrasive media upon any article to the fixture as it is vibrated.

Abstract: A deburring and cleaning machine and process designed to successfully clean work pieces such as castings, machined parts, and the like. The machine is characterized by a freely open work piece mounting plate movable in a predetermined pattern while simultaneously allowing free falling abrasion media to fall over, around and through the work piece. The method involves positioning a work piece in an open treating area, moving the work piece in a predetermined pattern through the treating area, and simultaneously free-falling abrasive media cascading over, around and through the work piece. The open treating area and the free-fall cascading of abrasive media provide improved cleaning and deburring of internal passageways, free falling abrasive media cascading, etc.
