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 compound 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 a bowl machine the angle between the weights can be varied to control the ratio between the forward motion and the vibratory motion.
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.
