Abstract (en)
[origin: WO2016087047A1] A rotary tool chuck for a unit for modifying a flat material, on which a sleeve (13) is intended to be fitted, comprises a cylindrical core (14), a peripheral wall (17), which is able to take up a rest position and a locking position exerting a radial pressure on the sleeve (13) so as to lock it in position on the chuck (12), a pressure fluid circuit (21), provided between the peripheral wall (17) and the cylindrical core (14), for exerting the radial pressure on the sleeve (13), and a cooling fluid circuit (24) for allowing circulation of a fluid at the cylindrical core (14) and for cooling the chuck (12).
