"SANDBLASTING MACHINE AND METHOD FOR FINISHING MOULDED OR CAST PIECES" A sandblasting method for finishing moulded or cast pieces, in which the pieces to be sandblasted are rotated in front of a sandblasting jet directed such that it strikes the pieces in a direction trasverse to the feed direction thereof.A machine for carrying out the method comprises a conduit in which the pieces being processed move forward under gravity by rolling and a sandblasting jet which attacks the interior of the conduit transversely.
