Abstract

The tool has a tool shank (which may be hollow) ( ), whilst the machine spindle has a connecting sleeve ( ) containing a recess ( ) to accommodate the tool shank. A clamping mechanism ( ) is located in the area between the tool shank ( ) and the connecting sleeve ( ). This mechanism has at least one clamping element ( ″), with radial movement, which acts as a wedge drive, providing axial clamping movement between the tool shank ( ) and connecting sleeve ( ). The clamping mechanism comprises an actuating nut ( ), which screws onto an exterior thread ( ) on the connecting sleeve ( ) and is coaxial in relation to the spindle axis. During the clamping procedure, the axial movement of the actuating nut can be converted into the radial movement of the clamping element ( ″), with the help of at least one connecting link ( ″).
