Abstract: A device for heat-treating shrink chucks for shank tools includes a receiving device for a shrink chuck, a heat treatment unit, and a measuring/computing unit for temperature measurement. The measuring/computing unit has a temperature sensor measuring a shell temperature of a shrink chuck in the receiving device, and a reflection sensor. The measuring unit applies a current test pulse before heat treatment on the shrink chuck in the heat treatment unit. A time/current curve ascertained for the test pulse is taken as a magnetic fingerprint for the shrink chuck in the heat treatment unit. An item of geometrical information for the shrink chuck is ascertained using the magnetic fingerprint. A reflection measurement is performed on the shrink chuck in the heat treatment unit. A temperature measurement on the shrink chuck performed by the temperature sensor in the heat treatment unit is corrected by the reflection measurement.

Abstract: A hydraulic expanding chuck having a main body which extends along a rotational axis and has a clamping part for receiving and clamping a shank tool and a shank part having a hollow shank for directly or indirectly coupling the hydraulic expanding chuck to a module of a modular tool system or to a machine spindle. The clamping part has a central receiving opening and, around the receiving opening, at least one pressure chamber to which fluid pressure can be applied and which is separated from the receiving opening via an elastically yielding expansion wall and is connected via a pressure duct to a pressure-generating device situated in the main body. The pressure-generating device is arranged axially in the region between the receiving opening and the hollow shank in a central cut-out, which is coaxial with the receiving opening and which opens into the hollow shank.

Abstract: The invention relates to a hydraulic expansion chuck comprising a main body (1) that extends along a rotational or longitudinal central axis (2) and is composed of a shaft part (20), for directly or indirectly coupling the hydraulic expansion chuck to a module of a modular tool system or to a machine spindle, and a clamping part (30), joined to the shaft part in a rotationally and axially fixed manner for receiving and clamping a shank tool. The shaft part comprises a receiving socket which extends towards the clamping part and has a central socket-opening in which a connection pin (31) of the clamping part, which pin extends towards the shaft part, is form-fittingly received. According to the invention, the clamping part comprises a stop which is radially offset from the connection pin and axially strikes the receiving socket.

Abstract: A clamping assembly includes a collet adapter and an expansion sleeve movably disposed in collet adapter and a draw pin movably disposed in the expansion sleeve. The expansion sleeve cooperates with the draw pin to define a containment system configured maintain the expansion sleeve within an axial envelope and a radial envelope within the collet adapter. Axial movement of the draw pin in the expansion sleeve within the axial envelope causes a portion of the expansion sleeve to expand radially outward to a predetermined maximum diameter to releasably clamp the collet in the collet adapter.

Abstract: A cutting tool includes a tool holding system having a clamping portion. The clamping portion includes an integrally formed one-piece inner coupling member that at least partially forms a clamping sleeve portion having a clamping bore for clampingly receiving a cutting insert. The clamping portion also includes an integrally formed one-piece outer coupling member that is circumferentially disposed about at least a portion of the inner coupling member. The tool holding system also has a mounting portion that is connected to one of the inner and outer coupling members. The inner and outer coupling members are captively and non-releasably engaged with each other via inter-engaged first and second engagement surfaces that are slidingly displaceable with respect to each other.

Abstract: A clamping device for clamping a workpiece or a tool or, more specifically, a tool holding fixture in a machine part of a machine tool includes a tension rod slidably mounted within the machine part; a clamping set movable by the tension rod between clamped and released positions; a tension spring dedicated to the tension rod so as to generate the pull-in force of the clamping set; and a release mechanism, by which the clamping set can be moved against the force of the tension spring into the released position by the tension rod. To make possible effective clamping at optimum force, the tension spring is clamped between first and second rod parts of the tension rod. The second rod part can move relative to the first rod part, and, as the clamping set moves into the released position, is compressed on both ends by the release mechanism by moving the two rod parts in opposite directions.
