Abstract: The invention relates to a method and a device for producing a split bearing arrangement, in which a top bearing part (6) is separated in several machining stations from a basic bearing part (5) that is monolithically joined thereto via a severing breaking process on a predefined plane of breakage (10) by applying a certain force, whereupon the two parts are joined back together by means of a screw connection comprising at least two screws. The basic bearing part (5) and the top bearing part (6) are fixed on an adapter device (1) that is conveyed from one machining station to another while the top bearing part is retained at least during some processes in the machining stations via a retractable auxiliary support (13) which is disposed on the adapter device and catches the top bearing part outside the area of the screw connection.

Abstract: A multi-spindle machining center for the chip forming processing of workpieces comprises a spindle group having at least two spindles arranged in a spindle row adjacent to each other to mount a chip forming tool, and a workpiece support, on which at least two workpiece holders, correlated with the geometrical arrangement of the spindles, for holding workpieces for a simultaneous processing by means of the spindles, are arranged, the workpiece support having a beam-like longitudinal support member bearing the workpiece supports, and the spindles are guided for a movement toward the workpiece support in a first axial direction on a spindle linear guide arrangement.

Abstract: A processing machine arrangement includes a processing machine with at least one tool spindle and with a tool magazine for offering tools to the processing machine for the machining of a workpiece. A method for the operation of such a processing machine arrangement is also provided. There is a robot with a multi-joint robot arm for providing the tool magazine with tools from a tool storage supply means and for removing spent tools from the tool magazine, and that the tool magazine includes a tool holder portion which is alternatingly able to be shifted, and more especially pivoted, into a robot access space for a tool change of the robot and into a spindle access space for a tool change on the tool spindle, with the tool holder portion having a tool holder for holding a tool.

Abstract: The invention relates to a device for fracture splitting of an annular section (12) of a workpiece, with a housing (34) for mounting the workpiece (10), during the machining, a laser device (30), for the formation of two diametrically opposed nicks in an inner circumferential surface (16) of the annular section (12) by fusion of the material using laser energy and a fracture splitting device (32), for the fracture splitting of the annular section (12) of the workpiece (10) into two pieces along a fracturing plane (5) given by the nicks, characterised in that the laser device (30) and the fracture splitting device (32) form a single machining station and are embodied such that the formation of the nicks and fracture splitting of the workpiece (10) are carried out from opposing sides of the workpiece (10).

Abstract: The invention relates to a device for machining workpieces, especially for chip removing machining. The device includes a spindle which is mounted on a first end of a pivoting arm in such a way that it can be linearly displaced in a direction parallel to the rotation axis of the spindle, and a console on which the pivoting arm is mounted by its second end in such a way that it can rotate about an axis parallel to the rotation axis of the spindle. The console can be displaced in a direction which is perpendicular to the displacement direction of the spindle in all of the pivoting positions of the pivoting arm.

Abstract: The invention relates to a machine tool, in particular to cutting machine tools. The inventive machine tool comprises at least two machining modules provided with at least one spindle with a horizontally oriented axis and at least one clamping module having a tooling surface for at least one part which is horizontally oriented and rotatable around a vertical axis. The clamping module includes structure for a rigid coupling thereof to the machining module. One or several clamping modules and/or machining modules are provided with at least one fictive midplane which is parallel with respect to the spindle axis. The machine tool also includes at least one pallet changing module which is connected to the clamping module asymmetrically with respect to the midplane.
