ABSTRACT:
A centrifugal disk finishing apparatus utilizing dry media comprising a finishing chamber including an upstanding wall and a rotatable disk forming the bottom wall of the chamber. The disk is mounted in such a manner that a precision gap, known as a seal, is provided between the lower edge of the upstanding wall and the periphery of the disk. The seal extends upwardly and inwardly from the periphery of the disk. The construction of the wall and the support of the wall and disk is such that the disk and wall are rigidly maintained in concentric relation in all conditions of operation and load and therefore gaseous fluid under low pressure utilized in the finishing apparatus can flow readily from a chamber beneath the disk through the seal during operation of the apparatus.
