In order to reduce the offset between the clamping force and the one which brings about unclamping of a chuck including a body (1) whose front face has radial slits (3) in which there slide jaw holders (4) provided with slideways, provision is made for each lateral face of the jaw holder to carry at least two slideways (8), preferably 4 to 8, which interact with the corresponding faces of the slits (3) and which have a certain flexibility so that despite the machining tolerances, all the slideways participate in holding the jaw holder during clamping. …<??>Advantageously, the front of the chuck is made of several parts (10) which define the slits (3) between them. …<IMAGE>… |
