ABSTRACT:
A centrifugal drum apparatus for finishing the surfaces of metal objects is disclosed, including a housing, a disk-shaped rotor member connected with the housing for rotation about a generally horizontal axis, and a plurality of finishing drums open at one end and having longitudinal axes arranged symmetrically about and parallel with the rotor axis, the finishing drums being rotatably connected with the rotor member. The apparatus includes a first drive assembly for rotating the rotor member about the horizontal axis, and a second drive assembly for rotating the finishing drums about their longitudinal axes. When metal objects are placed within the finishing drums and the rotor member and finishing drums are rotated, the surfaces of the metal objects are ground and polished through abrasion with the inner surface of the drums.
