A guide bush for a machine tool includes a belt pulley, a spindle, a collet, a sleeve, and a piston tool. The belt pulley receives rotary force from a servo motor of a machine tool. The spindle is combined with the inner circumferential surface of the belt pulley. The collet is combined with the inner circumferential surface of the spindle to be movable in the axial direction of the spindle to chuck a material. The sleeve is screw-combined with the collet. The piston tool selectively fixes the sleeve for the collet to rotate by the rotary force from the belt pulley in order to adjust the chucking force of the collet. Therefore, the present invention can adjust the chucking force of the collet while the collet chucks the material without an additional tool. Moreover, as the rotary force can be controlled precisely by the servo motor, the present invention can adjust the moving displacement in the axial direction of the collet precisely. As a result, the chucking force of the collet can be ...
