Vibratory finishing is a type of mass finishing manufacturing process used to deburr, radius, descale, burnish, and clean a large number of relatively small work pieces. 

In this process, the workpieces are belt fed into the tub of a vibratory tumbler which contains cone-shaped pellets of media and a cleaning liquid.  Here, the contents of the tub are vibrated causing the media to rub against the castings, yielding the desired result.

After the castings have passed through the vibratory tumbler, they are belt fed through a dryer and back to the operator.
