A batch finishing process used to deburr, radius, descale, burnish, clean, and brighten a large number of relatively small parts by using specially shaped media. The parts are placed into a tub of the vibratory tumbler. The contents of the tumbler and all of its contents are then vibrated. The vibration causes the media to rub against the parts, giving them the desired finish. This process can be done either wet or dry.

A burr is a raised edge or small pieces of material remaining attached to a workpiece after a modification. Deburring is important for quality and functionality not to mention aesthetics and the smooth operation of working parts. Deburring can also play a role in safety. The smallest burr can cause injury or “catch” during production causing unnecessary delays
