Abstract: A machine tool having at least one or more spindles that can be positioned in space, the spindle being mounted on displaceable slides by rods and the displacement of the slides leading to the spindle being positioned in space. A correction device is provided which defines the actual position of the spindle relating to one or more reference points.

Abstract: The invention refers to a machine tool with only one work spindle which carries and drives an exchangeable machining tool. Furthermore a tool supply is provided which has tool tongs for receiving machining tools. For exchanging and replacing the machining tools a relative movement is provided. It is suggested to share out the tool supply between at least two partial magazines.

Abstract: The invention refers to a machine tool with at least one headstock for one or more tool spindle(s) with a spindle head, where the headstock can be shifted in the direction of the spindle axis, the machining room of the machine tool is limited by a wall, the headstock projects through an opening into the machining room, and the tool spindle carries on its front end a tool projecting into the machining room. The invention is characterised by the fact that at least one guide block for the headstock is provided which can move on a guide rail, and the headstock carries the guide block.

Abstract: The invention refers, among others, to a loading system for a machining station which machines on work pieces, the loading system having a loading device which interacts with a pallet carrying the work piece. Several swivelling levers are arranged on the loading device in a way that they can be driven. The pallet is held by several swivelling levers on the gripping device.

Abstract: The invention refers to machine tools, in particular for the metal cutting machining of workpieces, for which several machining spindles are provided, and wherein a tool magazine serves for supplying and changing the tools of at least two machining spindles. At least a part of the supplied tools and the tools which have to be changed are arranged in the same plane.

Abstract: The invention refers to a production line comprising at least two machine tools which machine work pieces. The work pieces are conveyed on a supply line from a conveying line to the machine tool. After machining the work pieces are conveyed by a removal line from the machine tool to a conveying line. Supply line and removal line are arranged in different levels one above the other.

Abstract: The invention refers to a device for conveying goods as well as a conveying system for goods. The good runs on a conveying belt. The good has running treads, which are supported on the edges. The running treads are inclined.

Abstract: The invention refers to a conveying device for a production or machining line with at least one, in particular cutting, machining station. The conveying device serves for conveying workpieces by means of conveying aids, like pallets or workpiece carriers, a primary part of a linear motor being provided along the conveying path which creates a magnetic field, and the conveying aid being formed by the secondary part of the linear motor.

Abstract: The invention refers to a machine tool for the in particular cutting machining of work pieces. The machine tool carries at least two spindles. At least one of the spindles can move, in particular move back, axially to the spindle axis relatively to the other spindle.

Abstract: The invention refers to a production system, in particular machining line, which is formed, on the one hand, by one or more process modules which machine on work pieces and, on the other hand, is at least formed by one logistics module, and the logistics module provides a conveying of the work pieces, wherein the logistics module as a pre-assembled system module provides with and disposes of work pieces to a number of process modules, and the process module as system module can be connected to the logistics module.

Abstract: The invention refers to a machine tool where the work piece is conveyed in the working area of the machine tool by means of a conveying device, and the work piece is clamped in the working position by a clamping device. It is proposed that the conveying device provides the feeding as well as the removal of the work piece to and from the machine tool, and also the conveying of the work piece in the working area.

Abstract: The invention deals with a machine tool with a tool spindle holding device which is connected over at least one rod with a slide stand. The slide stand can move on a guide. The positioning of the tool spindle holding device is accompanied by the positioning of the slide stand. The tool spindle holding device carries at least two tool spindles.

Abstract: A Machining center in particular for cutting machining of at least one workpiece is proposed wherein at least said one workpiece is held by a clamping device, which can drive along at least one direction, and wherein a machining unit, which can drive along at least one direction, carries at least three tool spindles wherein each drives one tool, and wherein the relative movement necessary for the positioning and for the machining or the relative movement necessary for the machining and the positioning of said tool and said workpiece is carried out through the movement of said clamping device as well as through the movement of said machining unit.

Abstract: The invention deals with a machining installation comprising at least one transfer path which conveys a workpiece to several machining stations. In the machining stations at least one tool spindle is provided. The workpiece is moved while being machined by the tool spindles.

Abstract: The invention relates to a machine tool having at least one or more spindles that can be positioned in space, the spindle being mounted on displaceable slides by means of rods and the displacement of the slides leading to the spindle being positioned in space. A correction device is provided which defines the actual position of the spindle relating to one or more reference points.

Abstract: One or a pair of aligned dovetail grooves secure various shelves to supports depending upon whether the shelf is an upper or lower unit. Vertical supports have male dovetail projections formed on each end for mating with a groove. A wedge projection is formed on the support end adjacent to the male dovetail projection for wedging against the shelf in interference fit when the male and female elements are assembled. Various embodiments for the wedge projection are disclosed. The supports have a width less than that of the shelves so that the dovetail joints are only visible from the shelving rear. The wedge projections are sufficiently small so as to not be observable from the shelving front. A particular shelf construction employs upper and lower shelves each comprising a dual construction of an upper and lower member. A triangular brace is secured to the lowermost shelf for support when the shelving is hung on a wall.
