Abstract: A spindle unit for machine tools that includes a working spindle rotationally bearing-mounted in axially spaced spindle bearings in a spindle case, and an electric driving motor. The working spindle includes at its head side a clamping device for a tool and at its rear side a non-rotating ring cylinder for activating said clamping device via a rotating tie rod, and rotational bushing for supplying said tool with cooling and/or lubricating agents through a hydraulic conduit extending longitudinally through said working spindle. At least a segment of the non-rotating ring cylinder may be received in the rear end portion of said working spindle.

Abstract: The present invention relates to a handling apparatus 1 for use at a machine tool, comprising: a base body 2 which can be set up on a floor space, a storage body 3 which can be set up on the top side of the base body 2 and serves to store a plurality of workpieces or tools, and a handling robot 5, which is arranged on the base body 2 and has a gripper device 6 for receiving a workpiece and/or tool from the storage body 3 and for inserting the workpiece and/or tool taken from the storage body 3 by the gripper device 6 into a corresponding workpiece and/or tool support of the machine tool.

Abstract: A machine tool including a spindle oriented along a first direction with an adjustable chuck to receive a piece to be worked on. The machine tool further includes a transport device positioned essentially perpendicular to the first direction with deposit areas for the deposit of a number of the pieces to be worked on. The transport device is positioned such that each of the deposit areas may be moved into a transfer position in order to receive a piece to be worked on from the pertinent deposit area by the adjustable chuck or to release it from the adjustable chuck and to deposit it in the pertinent deposit area. An orientation device is provided that is configured to orient the piece to be worked on in a deposit area such that it may be received by the adjustable chuck in the transfer position.

Abstract: A machine-tool turret-type unit includes a turret disk that is free to rotate about a rotational axis, and a housing on which to mount the turret disk is provided. The housing includes at least one securing device to be secured to the securing section of the machine tool. The securing device includes at least one securing surface to rest against the securing section of the machine tool. The rotational axis lies within a first plane defined by the securing surface(s).
