A finishing assembly for vibratory finishing of workpieces in loose finishing media includes at least one generally annular finishing chamber which is driven by a drive assembly and supported by a support housing. The drive assembly consists of a crank shaft and a drive shaft which are rigidly connected to each other through a wedge-shaped gasket and oriented such that the rotary axis of the crank shaft and the rotary axis of the drive shaft intersect with one another at a predetermined angle. The crank shaft rotates within a first bearing hub which is rigidly mounted within the chamber and the drive shaft rotates within a second bearing hub which is rigidly secured to the assembly housing and which is actuated by an electric motor. The spatial vibration of the finishing assembly can be adjusted using a wedge-shaped gasket and/or by providing for horizontal displacement of the first bearing hub from the second bearing hub. The assembly housing acts as a reactive mass so that the finishing assembly experiences kinematic motion. Alternatively, the finishing assembly may include a second chamber to serve as a reactive mass, the second chamber being mounted either on the same level with the first chamber or underneath it. A special chute/groove arrangement can be provided to convey workpieces out of the first chamber and/or second chamber.
