In a clamping device for the coaxial clamping of a tool holder on a spindle of a balancing machine, which spindle is rotatable about an axis of rotation (3), the coupling shaft (8) is supported in the receiver opening only at discrete support points (11-15) which, in the peripheral direction, have spaces from one another and lie in three planes of action (E1, E2, E3) that are separate from one another and intersect the axis of rotation (3). Four rigid discrete support sites (11-14) are arranged in pairs in the first (E1) and second action plane (E2) and together form a rigid support in a first radial direction. In the third plane of action (E3) lying between the first and second planes of action, a fifth discrete support site (15) is formed which effects support in a second radial direction opposite to the first radial direction. |
