Abstract
Various clamping mechanisms are known for clamping shank-like tools such as drills, milling cutters and the like. The known clamping mechanisms often require long setting times involving long idle times when changing tools, particularly on machines with several spindles. The instant disclosure teaches a clamping mechanism allowing rapid tool change on the machine spindles and having good concentricity characteristics. A bayonet catch-like locking device is used for this purpose.
