Abstract (en)
[origin: WO2007035037A1] The present invention is to provide a synchronized clamping chuck for a machine tool, in which a plurality of jaws (30, 40, 50) move at the same time to clamp a work piece with hydraulic pressure increased by hydraulic oil pressurizing (20) in a state that a center of the work piece is positioned at a center of the chuck, and then other jaw clamps the work piece, so that the machining can be done in a state the work piece is clamped rigidly when the centers of the work piece and the chuck are coincident.
