A machining system for controlling and moving work tools during machining and assembly operations. The system has multiple drive-guide systems that allow work tools to be moved along all three perpendicular Cartesian axes. The drive-guide systems have rollers that are designed to fit and move along rails, thus altering the position of the work tools. A plurality of magnets apply axial pre-load to the rollers, keeping them adequately positioned on the rails. Likewise, a preloaded roller may be used to modify the radial force applied to the drive rollers. Both this radial and axial preload can be adjusted to reduce calibration and tolerance errors throughout machining and assembly processes.

A tool system for machining a workpiece is provided having a cylinder-shaped retaining shank that has a cutting head holder on an end surface facing the workpiece, a drive mount on an end surface facing the drive, a cutting head having at least one cutting edge, a cutting head hub corresponding to the cutting head holder on the retaining shank, a tool coupling with a tool interface, and a coupling hub corresponding to the drive mount. The coupling hub or the cutting head hub have elevated areas, with contact surfaces, distributed in circumferential and longitudinal directions of the coupling hub or the cutting head hub. The contact surfaces make contact on support surfaces on the drive mount or on the cutting head holder on the retaining shank. The drive mount or the cutting head holder is permanently connected to the coupling hub or the cutting head hub by a joining material in intermediate spaces between the elevations.

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).

A positioning device, in particular a tool positioning device, for a processing center that comprises a compound slide with a first slide movable in a longitudinal direction of the processing center and a second slide that can be moved in a transverse direction relative to the first slide. The first and the second slides have a matching offset configuration of the sides opposite each other, that bear guides and guide elements that interact with each other in order to guide the second slide in the transverse direction. These guides and guide elements are in part arranged at different heights in a vertical direction in such a manner that the second slide is guided on the first slide on at least two spaced apart guiding points, wherein the guiding distance between the guiding points varies during a traversing motion of the second slide relative to the first slide in the transverse direction.
