Abstract: A machine tool having a carrier device for workpieces or tools or tool spindles. A console supports the carrier and can be pivoted about a first axis (X) from the horizontal into the vertical position and beyond. The console is pivotably housed on carriages guided in the machine body. The carrier for a workpiece, a tool, or a tool spindle is arranged on the console, and a drive device is provided for the synchronous displacement of the carriages on guide rails fixed on the machine tool. The console is hinged via two crank-like arms to the stationary machine body in addition to being supported on both carriages to form a kniematic coupling.

Abstract: A tool changer for machine tools, the tool changer having at least one rotatable tool gripper, a supporting column for the tool gripper which can be lifted and lowered and rotated about a rotational axis, a mechanical cam gear for generating the lifting and rotating movements of the tool gripper, all driven by a drive motor connected to a cam barrel and intermediate gearing. The cam barrel has a tappet for the rotational drive of the tool gripper on its upper front and a cam curve or groove on its peripheral surface for the lifting movement of the tool gripper. The tappet drives a Maltese wheel supported on a shaft parallel to the rotational axis of the tool gripper. The Maltese wheel, the cam barrel, and the supporting column of the tool gripper are successively supported in a manner parallel to the axis.

Abstract: A workpiece table arrangement for a milling and drilling machine comprising a rigid machine tool frame comprising an upper cross girth, a machining unit movable on the front side of the cross girth along at least two coordinate axes by means of a motor and including a rotationally driven work spindle including exchangeable tools. The workpiece table is disposed in front of the machine tool frame and horizontally movable along at least one coordinate axis by means of a motor and comprises a tabletop for clamping at least one workpiece. The machine tool frame comprises two rigid side walls rigidly connected to each other by the upper crossbar and a front end.

Abstract: A machine tool, and in particular a milling and drilling machine, which includes a rigid base on which an inclined support surface pointing forward and upward is formed. The support surface forms a support for a workpiece support rotatable about the central axis and comprises a support supported on the support surface and rotatable about its central axis. A workpiece table is provided on a bent support portion of the support. The axis of the workpiece table forms an acute angle with the central axis of the support surface. The support surface is laterally offset with respect to the vertical central plane of the base so that its central axis forms an acute angle with the vertical central plane of the base, and the workpiece table assumes a forward tilted posture in intermediate positions within a rotational angle range.

Abstract: A machine tool with a driven tool spindle that is rotatable about a spindle axis that includes a tool exchanger including grippers to displace tool-holders or tools between a receiver position in the tool spindle and a storage position, or vice versa. The tool-holders or tools in these two positions are identically oriented, and the storage position and the receiver position are displaced with respect to each other along the spindle axis direction of the tool spindle. The tool exchanger possesses a transport mechanism that includes a carrier element pivotable about a pivot axis inclined with respect to the spindle axis, to which grippers pivotable about axes perpendicular to each other are connected. Guide elements are mounted so they may be driven and rotate about the first axis parallel to the pivot axis in the opposite direction to the pivot direction of the carrier element are included on the carrier element.

Abstract: A milling machine with a rotating drivable machine tool spindle perpendicular to a work piece stage slanting downward and away from the front side of the machine bed displaceable along the Z-axis that may be displaced via a first carriage along the Y-axis, and via a second carriage along the X-axis on guides mounted to the machine bed. A chip collection chamber is provided behind the work stage surface when in the operating position. The guides for the second carriage are provided on opposing struts of a portal frame parallel to the work tensioning surface, that is connected on its front side by means of lateral front support areas and on its rear side directly with the machine bed.

Abstract: A tool exchanging apparatus for a processing center, provided with at least one tool spindle (2), in which a tool (1) can be clamped and which can be moved in the direction of the spindle axis and at least also in a direction vertical to this direction, equipped with a tool magazine (3) and with two tool holding devices (4a) on a transporting device (4) with which the tool holding device (4a) can be moved to a tool exchanging position located in the movement region of the tool spindle (2), wherein one used tool (1) can be deposited from the tool spindle (2) and a new tool can be removed from the tool spindle (2). Each of the tool holding devices (4a), which are provided at least in pairs, is allocated to its own transporting device (4) so that the transporting devices can be moved back and forth independently of each other between the tool exchanging position and a tool receptacle (3a) of the tool magazine (3). The tool receptacles (3a) of the tool magazine (3) are movable in a circulating manner.

Abstract: A tool changing device for a tool machine having a tool spindle which can be moved at least in the spindle direction and with which a tool can be engaged in a spindle hand-over position. A tool magazine/storage area houses a tool to be changed in a magazine ready position with an orientation diverging from the spindle direction. A transport device is fitted with a tool holder which, by means of an operating device provided with a driving guide/guide path, swivels the tool about a swiveling axis during its transport from the ready position in the tool magazine and an orientation parallel to the spindle direction. The transport device is designed for an entire transport path between the magazine ready position and a spindle hand-over position. The transport device is aligned with the rotation axis of the stored tool. The swiveling axis runs perpendicularly to the transport direction and the spindle axis.
