Vibratory Finishing, also known as mass finishing, is a mechanical/chemical process for the deburring, radiusing, smoothing, polishing and degreasing of individual, mass produced parts.
Mass Finishing is the process of parts being submerged in media and compound (specially treated water) within a vibratory finishing machine. The machine vibrates causing the contents to move in a circular motion and the media to grind against the part to get the desired finish.
The Vibratory Finishing process is used for both very small and very large workpieces with either simple or very complex geometries.
