Abstract: The present invention relates to a machine tool for machining a workpiece. The machine tool has a motor spindle for the rotative actuation of a tool. The motor spindle is supported by a stand. A turning bearing is provided at the stand and the motor spindle at the turning bearing is pivotable and positionable about a first turning axis. At the motor spindle, a linear guide is provided, which enables an advancing movement of the tool parallel to the spindle axis.

Abstract: The invention relates to tool tongs for the releasable holding of a tool, for example in a machine tool. The invention is characterized in that the tool tongs are formed by a tongs basic element and a tongs clamping element interacting and connected with the tongs basic element, wherein in the tool holding position the tongs basic element and the tongs clamping element hold the tool clampingly at its gripping elements, wherein the tongs basic element and/or the tongs clamping element is/are formed of flat material or plate-like material, such as, for example, steel sheet or the like.

Abstract: The invention refers to a metal cutting machine tool, with a motor spindle, which is also used for moving a work piece between the preparation area and the work piece table. The invention also refers to a corresponding method and to a corresponding system.

Abstract: The invention refers to a machine tool with a work piece table, wherein a clamping or lifting means disposed on the work piece table is driven by temporary power transmission from outside the work piece table. The invention also refers to a corresponding method.

Abstract: The invention relates to a machine tool having a motor spindle for machining a workpiece. The motor spindle is supported by a stand, a turning bearing being provided at the stand, and the motor spindle is pivotable and positionable at the turning bearing about a first turning axis. At the motor spindle, a linear guide is provided, which enables an advancing movement of the tool parallel to the spindle axis. The machine tool has a workpiece support, which is movable and positionable along a preferably horizontally oriented workpiece guide and which is rotatable and positionable about a second turning axis.
