ABSTRACT:
Parts or workpieces are surface finished in a vibratory finishing chamber with loose finishing material. The parts or group of parts are isolated from each other by part-isolating means which travel with the material in the finishing chamber. The part-isolating means comprise transverse walls maintained in close proximity to the inner surface of the finishing chamber. Means are provided for bringing at least two transverse walls into closer proximity to the inner surface of the finishing chamber, advantageously, sufficiently close to prevent passage of substantial amounts of loose finishing material from passing between the transverse walls and the inner surface of the finishing chamber.
