ABSTRACT:
A chucking tool for non-positive precision chucking of a part such as a workpiece or the shank of a tool, for example. The tool consists of a base body, an expansion sleeve that is detachably mounted on a part of the base body which is elastically deformable in the radial direction, and a device for introducing a hydraulic medium into a pressure space provided between the expansion sleeve and the wall of the base body. According to this invention, the expansion sleeve is made of a comparatively thick-walled thermoplastic material, at least in its radially deformable part. According to another feature of this invention, there is at least one groove-shaped hydraulic medium channel in the area of the surface pairing of the expansion sleeve and the base body and it can be acted upon by the supply of hydraulic medium, for example, with a manually operated piston-cylinder unit provided in the base body.
