A machining unit for a machine tool includes a carrier head base, which on its rear side includes a carriage. The carriage can be coupled to axis guides and is longitudinally displaceable. The machining unit further includes a spindle carrier head held pivotably on the carrier head base. The spindle carrier head has a spindle with a tool holder. The carrier head base is provided with a damping unit. The disclosed machining unit provides increased precision of a machine tool. The machining unit may be incorporated in a machine tool.

A machine tool includes a bed including a bottom surface and legs arranged at three positions of the bottom surface. The bed includes two oblique sides arranged such that the bottom surface has a triangular shape. The machine tool also includes a first support surface arranged on the bed and extending along a substantially horizontal first axis, a work table supported by the first support surface so as to move along the first axis, a second support surface arranged on the bed and extending along a substantially horizontal second axis, which is perpendicular to the first axis, and a machining unit supported by the second support surface so as to move along the second axis. The second support surface is located higher than the first support surface.

A machine tool (1, 100) comprises a support structure (4, 104) and a machining head (8) bearing a mandrel (12). The machine further comprises at least one action device (20) contained on the support structure (4,104) and applied to it, which generates pushing or pulling actions on said support structure (4, 104) acting against the action of the weight of the head (8) thereon.

The present invention relates to a machine tool 100 for machining a workpiece, said machine tool 100 having the following: a support portion 30 on which at least one vertical guide 18, 32 is disposed; a machining unit 10 for machining a workpiece on the machine tool 100, said machining unit 10 being guided so as to be vertically movable on the at least one vertical guide 18, 32 of the support portion 30; a drive mechanism 20 having at least one drive 21 and at least one gearbox 22, said drive mechanism 20 being specified for driving a relocation of the machining unit 10 in the vertical direction along the at least one vertical guide 18, 32 of the support portion 30, wherein the machining unit is suspended from one or a plurality of gearbox portions of the at least one gearbox 22 of the drive mechanism 20 in such a manner that the centre of gravity 101 of the machining unit 10 conjointly with an effective point 12 of the suspension 11 of the machining unit 10 on the drive mechanism 20 is disposed in a common vertically oriented straight line 23.

A transfer center for machining at least one workpiece is disclosed, having a machine frame, having a plurality of preferably stationary machining spindles arranged in the machine frameparticularly in a machining head, having a workpiece carrier on which at least one workpiece to be machined is arranged by means of a respective clamping device, and having a workpiece manipulator arranged in the machine frame, onto which workpiece manipulator the workpiece carrier is flange-mounted and which is movable by drive means in at least one spatial direction in relation to the machine frame. To achieve a high machining accuracy in parallel machining, according to one proposal, the transfer centerin order to compensate for a deviation between the actual position and the desired position of the workpiece or workpieceshas a position compensation system with at least two pressure elements situated between the workpiece or workpieces and the machine frame, whose operating directions enclose an angle with each other.
