A chuck, especially for a device for machining pipes and the like as for instance for threading, deburring, cutting and similar operations, with chucking jaws pivotable about an axis substantially parallel to the axis of the chuck for chucking the workpiece to be machined. The chuck is mounted on a rotatable support, and the chucking jaws are positively connected to the driving motor so that the chucking jaws automatically move into their chucking position in response to the start of the motor. |
