摘要：
A hydraulic expansion chuck for chucking a tool such as a boring tool, a milling cutter, or other cutting tool. The hydraulic expansion chuck has an expansion bushing which can be deformed radially under the action of a pressure fluid contained in a pressure chamber to chuck a tool. Pressure is transmitted to the pressure chamber from a pressure generating unit via an annular gap positioned about the chuck axis.
