摘要
Process for clamping a drilling or milling tool of a circuit-board drilling machine in the drilling spindle, provided with a collet, of the same, in which process, to clamp a ringless drilling or milling tool with defined free working length in the collet of the drilling spindle, the collet, with the drilling-tool holding shank gripped provisionally, is fed in the direction of a measuring barrier provided in the clamping station until the tip of the tool reaches a predetermined distance greater than or equal to zero behind the measuring barrier, the collet of the clamping station being clamped and the collet of the drilling spindle being released, after which the collet of the drilling spindle is advanced until the desired free working length is reached, whereupon the collet of the drilling spindle is finally clamped.
