摘要： First and second shaving dies are mounted one above the other and are respectively provided with continuous shaving edges disposed adjacent to contoured annular facial surfaces which draw the shaved material away from the work piece as the shavings are removed by the associated shaving edge. An air nozzle mounted in proximity to the first die directs a jet of air across the contoured facial surface of the first die to blow the removed material away from the first die to prevent its interfering with the operation of the second die. The second die is located directly below the first die and is provided with a plurality of angularly spaced troughs lying immediately adjacent to and below annular facial surfaces on the second die for carrying the shavings from the shaving edges of the second die to a sump located below the second die.
