Abstract
A device for hydraulically clamping tools or workpieces, a tool holder or workpiece holder for short, has a clamping portion for clamping a tool or workpiece. An interior of the clamping portion has a plurality of chambers which are connected in fluidic communication by way of a channel system. In order to be able to change, in particular increase, the dynamic rigidity of the hydraulically clampable tool/workpiece holder, a central throttle point is arranged in the channel system. The central throttle point has an adjustment element with which a flow cross section in the central throttle point can be changed.
