Claim:
1. A tool holding system comprising: at least one tool or tool part, a drive or driven axle, a hydraulic clamping device, arranged on said axle and comprising a pressure chamber, pressurization of which causes an outer sleeve of the clamping device to expand radially outwardly to clamp the tool or tool part to the axle, an abutment configured to be fixed to the axle at a first axial side of the tool or tool part; a setting device including a base configured to be fixed on a second axial side of the tool or tool part and at least two separate setting members extending through the base and engagable with the tool, wherein the setting members are axially moveable to provide axial movement to respective different portions of the tool to adjust an axial position of the tool relative to the setting device when the hydraulic clamping device is in a non-clamping state; and a synchronization mechanism disposed in the setting device and connected to the setting members to synchronize the axial movements of the setting members.
