A method used to smooth the surface of a manufactured part. It is a form of tumbling, where the part or parts are placed in a barrel that is filled with various abrasive materials. It varies from standard tumbling in that there are two to four barrels that rotate around an axis at high speed, causing the barrels to sping in the opposite direction. This causes high loading and pressure in the drums as well as significant movement of the abrasive material. In additive manufacturing, it is a common post-processing method for smoothing the surface of metal parts that can survive the high loads.
