ABSTRACT:
A tool changer for machine tools having at least two tong-shaped grippers, the legs of which are formed for engaging with the ring groove at a broader end of a tool taper. The grippers are symmetrically mounted about the central axis of a carrier and are rotatable around the central axis with their legs pointing outward. The carrier is mounted on a support structure that has a drive for moving the carrier. In order to enable an earlier release of the tool taper from the collet chuck in the work spindle, and thus faster tool changes, at least one leg of the grippers is extended to form a protruding holding finger.
