ABSTRACT:
The clamping device has two jaws between which a workpiece to be machined is immobilized on the table of a machine tool. Each jaw is supported by a carriage, and the carriages are coupled so as to move in a mirror symmetric fashion with respect to a plane orthogonal to the path of the carriages and at rest relative to the device. This avoids adding up tolerances of the shape of the workpiece with tolerance in the position of the clamping device relative to the machining tools.
