Abstract
A chucking device for accurate mutual fixation of disk-shaped parts or rotationally symmetrical parts. The device has a chucking element that engages with members in a form-fitting manner and has an expansion sleeve that together with the chucking element forms the border of a pressure chamber filled with an incompressible medium. Due to a relative axial movement between the chucking element and the expansion sleeve, the medium enclosed in the pressure chamber is pressed against the wall of the expansion sleeve, which thus comes in pressure contact with the corresponding peripheral surfaces of the two members.
