Abstract: A positioning and clamping system, in particular for positioning and clamping a workpiece-bearing pallet 1 on a pallet receiving table 2, consists of at least two conical supports 4 arranged spaced from each other on the pallet receiving table 2 and at least two tapered sleeves 3 adapted to cooperate with the conical supports, the tapered sleeves being connected to the pallet 1 on the side which is to be located on the table. The at least one cone angle ?1, ?2 of one of the conical supports 4 and the tapered sleeve 3 adapted to cooperate therewith has an angle size which is suitable for the introduction of a self-locking connection between the support and the tapered sleeve upon cooperation thereof.

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 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 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 relates to a pallet changing system for changing the pallet carrying the workpiece in a machine tool, in particular in a machining center.

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.
