| Zusammenfassung: | The clamp is activated by a pressure tube (5) coaxial with the machine tool spindle. For clamping a spring (7) exerts a first axial force on the pressure tube to which forces are added by a first air pressure introduced through a conduit (902) in a clamping pressure chamber arranged between axially fixed walls (81-85) and walls (810-850) fixed to the pressure tube. Unclamping is obtained by a second air pressure introduced through another conduit (912) in an unclamping pressure chamber arranged between the axially fixed walls and the walls fixed to the pressure tube. |
