The Function Principle
of Multi-Taper Clamping Tools

Multi-taper clamping tools are the best choice in case of greater tolerances and more loading clearance In the automated process the demand for high loading clearance intends to cover a maximum part range without retooling. The function principle of multi-taper tools allows higher loading clearances than conventional hydraulic expansion tools. The clamping sleeve is mounted on the base body. Due to a special thread profile and axial force the clamping sleeve moves axially. The result is a fully cylindrical expansion which leads to workpiece clamping. Depending on the application and the clamping diameter, tolerances up to IT 13 can be obtained.
