Abstract: In order to save the investment for a separate cold rolling machine for applying threads etc. a cold rolling unit is placed in a moveable manner onto the Z-drives of a turning machine wherein the cold rolling unit can be configured much larger and much more stable and with less wear than a cold rolling unit used in a tool revolver. Even parallel processing through turning and rolling is facilitated.

Abstract: A machine tool for the production of teeth on workpieces is provided, comprising a workpiece holding device, a cold rolling device for the production of rough teeth on at least one workpiece held by the workpiece holding device by way of cold rolling and a cutting machining device for the fine cutting machining of the rough teeth of the at least one workpiece which is held on the workpiece holding device.

Abstract: A method for manufacturing a ball cage of a joint, comprising an inner side, an outer side and windows between the inner side and the outer side, is provided, wherein a blank is clamped on a workpiece fixture of a machine tool, with a clamping area of the blank lying outside of a machining area, and wherein the inner side, the outer side and the windows are machined by the same machine tool without reclamping the workpiece.

Abstract: A process of producing profiled tracks for joint parts is provided, wherein a cutting tool acts on the workpiece, a workpiece machining being performed with the cutting tool during the relative forward movement between workpiece and tool, and a workpiece machining being performed with the same cutting tool during the return movement following the forward movement.

Abstract: In a machine tool comprising at least one tool carrier and at least one moveable workpiece carrier with which one or more workpieces are positionable for machining, a tool can be changed in a simple manner by providing a tool holding device connected to the at least one workpiece carrier.
