摘要： Workholding apparatus for mounting a workpiece (6) on a machine tool, the apparatus comprising a diaphragm chuck portion (2) and a tailstock portion (4). The chuck (2) includes a backing ring (70) with face portion (74) attached to the diaphragm (44) with the backing ring (70) having a centering locator guide (76) for centering and stopping the axial advancement of a workpiece in the chuck (2). The chuck (2) also includes a support ring (106) including material (109) located at the periphery thereof for sealing the area between the chuck and the workpiece and dampening vibrations brought about by the machining process. The tailstock portion (4) comprises a rotatable tailstock support (112) having at least one workpiece seating surface (117). The tailstock includes a centering locator guide (114) extending axially from the tailstock support (112) and having a generally curved outer surface (115) for centering the workpiece in the chuck (2). The tailstock portion (112) also comprises an outwardly flaring housing cover (118) including an end flange (124) and sealing means (126) whereby relative axial movement of the tailstock (112) toward the chuck (2) provides for the cover (118) to fit over a workpiece mounted in the chuck with the sealing means (126) contacting a surface of the workpiece radially inward of that portion of the workpiece being machined. The sealing means (126) preventing the introduction of contaminants into the workpiece (6) and chuck (2) and also providing for dampening of vibrations from the machining process.
