The method includes the steps of positioning a workpiece (50) with a centering surface (51) on a centering clamping member (32) of a chuck (1), pressing a radial contact surface of the workpiece against a clamping surface (27) of the chuck (1) with a first force, centering the workpiece (50) by clamping the centering clamping member (32) against the centering surface (51), and pressing the radial contact surface (52) of the workpiece (50) against the clamping surface (27) of the chuck (1) with a second force, the second force being greater than the first force. The chuck comprises a centering clamping member (32) having a variable diameter, a radially extending clamping surface (27), which is adjacent to the centering clamping member (32), a movable clamping element (18), a first spring element (43), via which the centering clamping member (32) can be moved into a clamping position, a second spring element (21), via which the clamping element (18) can be loaded with a first force, a third spring element (13), via which the clamping element (18) can be loaded with a second, higher force, and an axially movable actuating device (8) by which the centering clamping member (32) and the clamping element (18) can be moved into a release position against the force of the first and third spring elements (43, 13).
Method for centering and clamping a workpiece, in particular an articulated shaft, in a balancing machine, comprising the steps of positioning a workpiece with a centering surface on a centering clamping member of a chuck, pressing a radial contact surface of the workpiece against a clamping surface of the chuck with a first force which still allows radial movement of the workpiece, centering the workpiece by clamping the centering clamping member against the centering surface of the workpiece, and pressing the radial contact surface of the workpiece against the clamping surface of the chuck with a greater second force which clamps the workpiece.
Chuck for centering and clamping a workpiece, in particular an articulated shaft, in a balancing machine comprising a centering clamping member with a centering portion having a variable diameter, a radially extending clamping surface, which is adjacent to the centering clamping member, a movable clamping element for axially pressing the workpiece against the clamping surface, a first spring element via which the centering clamping member can be moved into a clamping position, a second spring element via which the clamping element can be loaded with a first force, a third spring element, via which the clamping element can be loaded with a second force, and an axially movable actuating device by which the centering clamping member and the clamping element can be moved into a release position against the force of the first and third spring elements.
