Patent ID: 8529420

Claim:
A machine tool for processing workpieces, the machine tool comprising: a machine bed, two side walls, which side walls are arranged to be substantially parallel to one another, which side walls are arranged respectively with a side wall bottom side on the machine bed, and, which side walls respectively have a side wall top side, a z-slide, which z-slide is arranged in the region of the side wall top side on the side walls, and, which z-slide can be moved by means of a z-drive motor in a horizontal z-direction on the side walls, an x-slide, which x-slide is arranged on the z-slide, and, which x-slide can be moved by means of an x-drive motor in a horizontal x-direction on the z-slide, and, a rotary-driven tool spindle for mounting a tool, which spindle is arranged suspended on the x-slide, and, which spindle can be moved by means of a y-drive motor in a vertical y-direction on the x-slide, wherein the side walls each comprise a basic body, a support projection, and a front overhanging projection arranged thereon, and wherein: each of the front overhanging projections is in alignment with the associated basic body so that the z-slide can be moved on both the respective overhanging projection and the respective basic body, and wherein first spaces are formed directly underneath the front overhanging projections, and wherein a second space lying between said first free spaces forms a processing space for processing a workpiece with the tool mounted on the tool spindle, and the machine tool further comprising: at least one workpiece positioning unit for positioning the workpiece to be processed, the at least one workpiece positioning unit being positioned in the processing space and in the first spaces, each support projection being arranged directly below a respective one of the front overhanging projections, the at least one workpiece positioning unit is supported on an upper surface of each of the support projections, said upper surfaces being spaced from one another in the x-direction.
