| Zusammenfassung: | A hydraulic chuck includes a center bore for receiving a tool shank. At least one closed cavity is disposed in the chuck body adjacent the bore and extend circumferentially by a distance less than 360 degrees. The cavity containing device communicates with the medium for pressurizing the medium to radially deform and expand the bore wall from a normal diameter to a larger diameter to enable the tool shank to be moved into or from the bore. A depressurizing of the medium causes the bore wall to radially retract to the normal diameter for clamping the member in the bore. |
