Abstract
A detachable fixture of a rotary machining tool (3) on the tool spindle (2) of a machine tool and in particular of a grinding wheel flange (4) on the spindle nose (1) of a grinding spindle (2) is provided with two clamping rings. By means of the Cardanic located clamping rings (10, 13), the clamping force F generated by turning a clamping screw (7) is distributed uniformly on the spindle flange (6). The tool fixture according to the invention permits even large and heavy driven tools with high demands on stiffness and repeatability with respect to radial and axial runout and quality of balance to be changed with little time expenditure.
