Abstract

Such a work spindle has a clamping device with a clamping rod (7) that is spring-loaded and acts on clamping elements (6) which can engage in a hollow shaft taper of the corresponding tool (2). The correct chucked position of the tool (2) that has been mounted is determined by means of the axial position of the clamping-rod head (9), using a sensor facility (11) that generates a release signal for spindle start-up. The sensor facility (11) comprises a sender (12) and a receiver (13) for a measurement beam (14), whose length can be determined in an evaluation unit. The measurement beam, directed in the direction of the stroke of the clamping-rod head, or roughly in that direction, runs between the clamping-rod head (9) and a site on the work spindle fixed with respect to the frame; its length is compared in the evaluation unit with a length value which can be entered or preprogrammed, and if these two values agree, the start-up release signal is generated.
