ABSTRACT:
The chuck has a mounting body with an associated chuck assembly and a pivot device. For clamping of a workpiece at least one chucking jaw can adjustably be swung away from its chuck assembly, and the clamped workpiece, together with the chucking jaws can be turned about a pivot axis which extends perpendicularly with respect to the axis of rotation of the operational spindle of the lathe and with respect to the axes of operation of the workpiece, into pivot positions determined by the directions of the axes of operation. For workpieces with a pair of axes of operation, which are disposed at a distance with respect to one another, the mounting body is comprised of a base member and a turning member. The turning member is journaled for rotation at the base member so as to be able to revolve about a turning axis which extends parallel to the axis of rotation of the operational spindle and which intersects the pivot axis at predetermined distance. The turning member can be locked at the base member in the two turning positions, in which the two axes of operation cross the pivot axis.
