Abstract: An apparatus for machining a workpiece has a housing having a vertical front wall and first and second side walls extending generally perpendicularly back from outer edges of the front wall, directed horizontally oppositely away from each other, and defining first and second planes themselves delimiting a space. First and second vertical guides on the first and second side walls outside the housing carry first and second vertical slides moveable vertically on the first and second vertical guides of the first and second side walls. First and second horizontal guides on the first and second vertical slides carry first and second horizontal slides movable horizontally on the first and second horizontal guides of the first and second vertical slides between the first and second front work stations and the first and second rear transfer stations.

Abstract: A workpiece is machined using a first cutting tool and subsequent cutting tools in a predefined time sequence. The sequence of cutting tools defines a sequence of previous and subsequent cutting tools, with each previous cutting tool being replaced by a subsequent cutting tool in the course of the machining operations. Each previous cutting tool, which is replaced by a subsequent cutting tool, is deposited at a defined storage place in a tool magazine. When being put back into the tool magazine, the previous cutting tools are distributed to the storage places in a spatial sequence which is different from a spatial sequence at the start of the machining operations and which substantially corresponds to the time sequence.

Abstract: An apparatus on a machine tool for machining workpieces, preferably for machining workpieces by removing material, is provided to control functions of the machine tool and to program and/or test the machining of workpieces and/or to test the machine tool itself. The apparatus is provided with at least one display unit and at least one input unit, whereby masks for displaying and/or for inputting, via the input unit, machine and/or control parameters are displayable on the display unit. A start matrix having a grid of fields, which are stored in a geometrically addressable manner and are preferably arranged in rows and columns, can be displayed on the display unit, the input unit which is separate from the display unit being able to be used to select each field via its geometrical position in the grid at which it is displayed on the display unit, and the assigned function being able to be immediately triggered or a mask being able to be immediately displayed on the display unit by activating a field.

Abstract: A machine tool for cutting machining of work pieces has a tool spindle and a work piece spindle. The work piece spindle is a hollow spindle having a through hole extending through the spindle and a holding mechanism for holding a work piece at one end. The work piece held in the holding mechanism can be machined through the through hole by means of a machining tool held in the tool spindle.

Abstract: The invention relates to a machine tool for introducing bores into a workpiece, said machine tool comprising a machine frame, a drilling tool holder which is arranged on the machine frame and has at least one tool spindle, and a workpiece carrier which is arranged on the machine frame, the boring tool holder and the workpiece carrier being displaceable in relation to each other in a direction of displacement. A longitudinal direction of the at least one tool spindle is oriented transversally in relation to a horizontal plane, and the drilling tool holder is arranged on the machine frame in such a way that it can be pivoted in relation to the workpiece carrier, so that inclined bores can be introduced into the workpiece.

Abstract: A machine tool for the cutting machining of workpieces, in particular of metallic workpieces, has a first and a second tool spindle for receiving a first and a second machining tool, and it has a first and a second workpiece carrier for receiving a first workpiece and a second workpiece. The first tool spindle is movable relative to the first and to the second workpiece carrier in order to selectively machine the first or the second workpiece. Moreover, the first workpiece are movable relative to one another in order to transfer a workpiece from one workpiece carrier to the other workpiece carrier. The second tool spindle is movable relative to the second workpiece carrier in order to machine the second workpiece.
