A cutting tool holding mechanism for detachably holding a cutting tool includes: a collet chuck configured to clamp and unclamp the cutting tool; a piston disposed deeper on the proximal side of the spindle than the collet chuck and configured to urge the collet chuck by the pressure of a fluid supplied from the proximal side of the spindle in the direction from the proximal side toward the distal end side of the spindle so that the collet chuck unclamps the cutting tool; a spool valve provided in the piston and configured to open thanks to centrifugal force at the time when the spindle is turned, so as to supply the fluid fed from the spindle side to the cutting tool.

A tool changing mechanism includes a tool base housing, a mandrel disposed therein and having a chamber and a keyway provided axially, and first and second linked units. A first shoulder portion is provided at an end of the keyway, and pulling jaws are disposed at the other end. The first linked unit has a first pulling rod, an end of which has an external thread, and the other end has a connecting portion driven by a pneumatic cylinder. The second linked unit has a second pulling rod, an end of which has an internal thread, and a pressing head is disposed at the other end. The second pulling rod has a sliding key located in the keyway. The first pulling rod is screwed into the second pulling rod, and the relative screwing rotation therebetween attains tool pulling for fixing or tool loosening for removing the cutting tool.

In a device, in particular machine, for producing Wiegand wire from a wire, in particular pulse wire, and a method for operating a device, the device having a first clamping chuck, a second clamping chuck, and a third clamping chuck, the wire being fed through each of the three clamping chucks, in particular so that the wire is able to be connected in a releasable and torsionally fixed manner to the three clamping chucks, in particular able to be connected to the three clamping chucks in a releasable, torsionally fixed and nonpositive manner. The clamping chucks are set apart from one another in the wire direction, and the second clamping chuck is situated between the first and the third clamping chuck in the wire direction. The second clamping chuck is rotatably mounted so that a torsion is able to be applied to a first wire section and the reverse torsion is able to be applied to a second wire section, the first wire section being situated between the first clamping chuck and the second clamping chuck, the second wire section being situated between the third clamping chuck and the second clamping chuck. The distance in the wire direction between the first and the second clamping chuck is controllable and/or regulatable with the aid of a first linear actuator, and the distance in the wire direction between the second and the third clamping chuck is controllable and/or regulatable with the aid of a second linear actuator.

A chuck for clamping workpieces or tools in a clamping space with a clamping force (F). The chuck includes at least two chuck jaws movable in translation along one clamping plane (E) in the direction of one center Z of the clamping space and a gear train located at least largely within the chuck for transfer of a driving torque of a drive motor, which can be coupled to the gear train by coupling means of the gear train, to the chuck jaws for movement of the chuck jaws. The coupling means able to be coupled to a corresponding coupling connection of the drive motor. The movement from the maximum size of the clamping space to the minimum size of the clamping space is executed via the gear train from the drive motor.
