| PURPOSE:To improve accuracy in rotation and machining by making claws unclamp when both pistons for operating plungers are moved in each direction respectively, and making said claws clamp when said both pistons are restored, separating a work carry from an operating mechanism. CONSTITUTION:When oil, which is fed under pressure through a pressure passage 73, flows into a pressure chamber 69, a rear side piston 65 is moved backward and an operating flange part 70 is brought in contact with the front faces of the four supporting part 55, to support a work carry 41, whereas, a front side piston 67 is moved forward with its front side being brought in contact with plungers 53, which, in turn, is moved forward, causing both clamping claws 45, 45 to unclamp. When the pressure oil flows out by opening the passage 73, the piston 65 is restored by means of springs 71, causing the operating flange part 70 to be separated from the supporting parts 55, whereas, the piston 67 is restored by means of the springs 72 and separated from the plungers 53, both of the clamping claws 45, 45 clamp a workpiece W by means of four springs 48, and the plungers 53 are restored to their original positions, separating the work carry 41 from an operating mechanism 61. | ||||||

| PURPOSE:To enable automatic chucking of a work, by so constituting that a pair of tightening metal fittings is made to slide in a radial direction in a receding state from each other by centrifugal force due to a rotation of a main spindle and the work, which is made to penetrate through a long hole of each of the tightening metal fittings, is pinched between inner ends of the long holes. CONSTITUTION:When both ends of a pillarlike work 5 are supported by a center 3 provided by inserting it into a tapered hole of a main spindle 1 and a center 4 provided by inserting it into a tapered hole of a tail stock, the work 5 is made to support after penetration of the work 5 through long holes 16, 17 of a pair of tightening metal fittings 11, 12. When a face plate 9 is revolved by revolving the main spindle 1 under this state, both the tightening metal fittings 11, 12 are slided in a radial direction in a receding state from each other by applying more strong centrifugal force than bounce of a compression coil spring 20 to each of the tightening metal fittings 11, 12. An external circumferential part of the work 5, consequently, is chucked between the inner ends of the long holes 16, 17. When grinding work is completed and a revolution of the main spindle 1 is suspended, both the tightening metal fittings 11, 12 are restored by the bounce of the spring and the above mentioned chuck is released. | ||||||

| During machining of workpieces, particularly crankshafts, in a central ren of the workpiece, both tips at opposite unmachined ends are axially retracted from the workpiece; both machined ends of the workpiece are clamped centered with the radial clamping members. During the machining of one workpiece end, the workpiece is clamped equalized at the oppositely located end and during the machining of the central region is clamped centered at this end. A workpiece after end machining and before machining of the central region is relieved for elimination of existing axial tensile-strength pressure stresses. Before the machining of the central region there is applied an axial tensile-strength stress upon the workpiece. Apparatus for carrying-out the method includes two oppositely located main spindles and chucks, which have radially and axially adjustable clamping elements and having two oppositely located centering tips, which are adjustable axially relative to the clamping elements respectively the chucks. One chuck has centering-clamping clamp elements and equalizing-clamping clamp elements which are radially adjustable independently of each other. The centering and the equalizing-clamping clamp elements are adjustable axially in common. One chuck is provided with a load-relief device which is provided with a piston-cylinder-unit. The one chuck for axial stress loading of the clamped workpiece is adjustable by engagement of the piston. The one chuck is a clamping-tong chuck arrangement. | ||||||

| A chuck for clamping a discoid portion of a work piece includes a base, at least two fixed clamps secured on a front end surface of the base, a movable clamp adjacent to the front end surface of the base and a pin secured to the front end surface of the base. The pin is adapted to fit in a hole formed in the discoid when the discoid is mounted on the chuck wherein the hole has a larger diameter than the pin. Furthermore, the pin is positioned radially inwardly of the movable clamp toward the chuck center and oriented so that the two fixed clamps are equiangularly spaced about and equidistantly spaced from the pin. As a result, the discoid may move relative to the pin and toward the two fixed clamps, without rotation thereof. Accordingly, the centroidal axis of the discoid may be aligned with the rotational axis of the chuck so that precision machining may be achieved. | ||||||
