A centrifugal finisher uses centrifugal and rotational forces for finishing at least one object. A fixed, non-rotatably outer vessel has an inner surface and a central axis. At least one inner vessel is positioned inside the outer vessel and is adapted to hold an object to be finished. The inner vessel has an outer surface. At least one intermediate roller is positioned between the inner surface of the outer vessel and the outer surface of the inner vessel and engages the surfaces of respective outer and inner vessels. A drive mechanism rotates the inner vessel around the central axis of the outer vessel, thereby causing rotation of the inner vessel by engagement of the inner vessel with the intermediate roller which moves by rotation along the inner surface of the outer vessel.
