Abstract
Form-transmitting clamping of a tool with a shaft in an opening of the tool receptacle by shrinking with heating and cooling and adjustment of an axial insertion depth of a shaft in an opening of the tool receptacle, the method includes placing a movable contact piece on a free end of a tool for positioning the tool coaxially to the tool receptacle, clamping the tool between the contact piece on the one hand and a counterforce which acts opposite on the tool and oppositely to an insertion of the tool in the opening of the tool receptacle on the other hand before starting a heating, retaining the shaft clamped during the heating, and stopping the heating after reaching a predetermined nominal value during insertion of the shaft in the opening of the tool receptacle.
