FIELD: process engineering.
SUBSTANCE: invention relates to machine building and may be used for finishing parts in free state. Rumbling device comprises rumbling drum with face jaws inclined relative to drive shaft. Said conical drum features axis making acute angle with rotational axis. Drum face jaws are shaped to ellipsoid and turned in rumbling device conical surface axis relative to each other. Besides, they are arranged at 10° - 90° relative to each other.
EFFECT: higher efficiency of processing, expanded performances.
