Vibratory finishing is a type of mass finishing manufacturing process used to deburr, radius, descale, burnish, clean, and brighten a large number of work pieces. The key to achieving the desired finish is the proper media, correct chemical composition, time and vibratory amplitude. The tub or bowl of the vibratory machine and all of its contents are then vibrated. The vibratory action causes the media to rub against the work pieces which yield the desired result. Depending on the application this can be either a dry or wet process.
