摘要： An induction heating device for a shrink-clamping and/or unshrink-unclamping of tools into and/or out of tool holders has an induction heating unit with at least one first inductor and at least one second inductor, which is preferably realized separately from the first inductor, wherein the first inductor and the second inductor are configured to respectively expand at least a portion, in particular different portions, of the tool holder by inductive heating in a shrink-clamping and/or unshrink-unclamping process, and has an electric supply unit,
wherein the inductors are configured to output respectively different energies to different subregions of a tool holder, which are in a heating operating respectively encompassed by the inductors, as one of the inductors has more windings than the other inductor, in particular by at least 10%, preferably by at least 20% and preferentially by at least 30% more windings, and/or as the electric supply unit is at least configured to operate the first inductor and the second inductor in different manners.

摘要： The invention relates relates to a clamping system for clamping an object (1), in particular for clamping a cutting tool in a machine tool, comprising an accommodating bore (4) for accommodating the object (1) to be clamped, a threaded bore, which extends in the wall of the accommodating bore (4) transversely to the longitudinal axis (12) of the accommodating bore (4), and a clamping screw (6), which can be screwed in the threaded bore in order to selectively clamp or release the object (1) in the accommodating bore (4) in accordance with the screwing position of the clamping screw (6). The invention further relates to an intermediate element (9), which is arranged between the clamping screw (6) and the object (1) such that the clamping screw (6) touches the object (1) to be clamped (1) not directly, but rather indirectly by means of the intermediate element (9). According to the invention, the threaded bore is preferably arranged eccentrically in relation to the accommodating bore (4).
