A chucking device for tools or workpieces having a cylindrical or slightly conical chucking surface. The chucking device includes body (1), which is provided with truncated cone-shaped surface (3), cavity (4) located inside the surface and along a substantial portion of the axial extension thereof, and a pressurizing member located in body (1), by which the cavity as desired can be subjected to pressure by means of a medium. The device further includes holder (9) for tool (11) or workpiece (18) which is provided with a surface having a conical shape substantially corresponding to that of body (1), cylindrical surface (10) which is concentric with the conical surface, and slits (12) which are open at one end and extend through the wall of the holder. The device also includes clamp ring (15) which can be screwed on threads arranged in the body concentrically with the conical surface for causing the conical surface of the holder to contact the conical surface of the body. |
