Damping elements for tool chucking systems for damping vibrations and shocks that occur during machining in the case of force-fitting clamping of tools in a tool receptacle or on the tool itself. At least one damping element consisting of a shape memory alloy having a mechanical effect is provided in a tool chucking system or on the tool itself, such that the damping element provided in the chucked state in the force flow of the chucked elements is present in a reversible and hysteresis-dependent state by way of a mechanical force action and the associated crystalline conversion via the pretensioning of said damping element and leads to dissipation of mechanical energy. The mechanical energy to be damped is a cyclical vibration or represents a non-cyclical overload which is transmitted in the form of shocks.
Damping elements for tool chucking systems for damping vibrations and shocks that occur during machining when force-fittingly clamping tools in a tool receptacle or on the tool itself, wherein at least one damping element made of a shape memory alloy having a mechanical effect is disposed in a tool chucking system or on the tool itself, such that the damping element, which in the chucked state is disposed in the force flow of the chucked elements, is in a state of reversible and hysteresis-dependent deformation with its associated crystalline transformation as a result of the clamping element having been pretensioned by the action of a mechanical force, which leads to dissipation of mechanical energy, with the mechanical energy to be damped being a cyclic vibration or constituting a non-cyclic overload which is transmitted in the form of shocks.
A system comprising a tool receptacle and/or a tool having at least one damping element for damping occurring vibrations and shocks, wherein this damping element is configured in the form of a shape memory element which is completely or partially made of a shape memory alloy.
