Abstract
A hydraulic expanding chuck for receiving and clamping a tool with a shank. The hydraulic expanding chuck has a main body, which on an axial side has a clamping section that extends along a longitudinal central axis of the expanding chuck and has a clamping part lying in a neck region and in which are formed a central receiving opening for receiving a tool shank and a chamber system to which a fluid pressure can be applied. The chamber system comprises at least one pressure chamber, which is separated from the receiving opening in the radial direction by an expansion wall yielding elastically under the fluid pressure, and which can be supplied with fluid pressure by means of at least one axial pressure channel running from a piston clamping mechanism accommodated in a clamping region of the hydraulic expanding chuck.
