Vibratory Finishing, unlike hand polishing, buffing, filing, belting, does not overly depend on the skill of the operator. Instead, it is a mass finishing technique lending itself to batch security and uniformity for the lot. Parts are typically bulk loaded for a long batch process or continuously fed into a vibratory machine for a cellular manufacturing system. Media of various compositions and sizes are used in the bowl. The vibratory action causes the media to act like thousands of small files scrubbing the parts. A chemistry is used to assist the cleaning/finishing action of the media. The amplitude and frequency of the vibration can be varied to control the finishing of the parts. In vibratory finishing equipment, the angle between the upper and lower weight system can be varied to adjust the ratio between the forward feed motion and the rolling action of the media mass. The process is commonly used to deburr, burnish, descale, clean, radius, and improve surface finishes. It is ideal for finishing parts prior to painting, plating, heat treating, anodizing, coating and sometimes it is the ideal final finish.
