This relates to a disc cleaning machine wherein abrasives are thrown at a disc as it travels along a predetermined path and wherein the disc is rotated as it travels along that path. A principle feature of the machine is that discs are conveyed along a path by a pair of cooperating screw type conveyors while the discs are supported on a pair of support shafts which rotate and rotate the discs so as to ever changingly present surface portions of the discs to the abrasives. The workpieces are automatically fed into the machine by way of a notched feed wheel and at the end of the cleaning operation, the workpieces drop off of the support shafts and down a discharge chute so that the operation is automatic. |
