Abstract: The present invention relates to a machine tool for machining surfaces of in particular rotationally symmetrical workpieces (7), comprising at least one machining station (1, 2), at least one loading station (3) and/or unloading station (4) for the workpieces to be machined and/or the machined workpieces, a loading device (6) for transferring the workpieces (7) from one station (1, 2, 3, 4) to an adjacent station (1, 2, 3, 4), characterized in that the loading device (6) comprises a rotatably driven sliding device (8), a drive (9) for the sliding device (8) and a rotatably mounted and braked guiding device (10), wherein driving the sliding device (8) initially causes a workpiece (7) to be pressed by the sliding device (8) against the guiding device (10), after which the workpiece (7) abutting against the sliding device (8) and abutting against the braked guiding device (10) indirectly moved by the sliding device (8) is transferred onto a circular arc track from one station (1, 2, 3, 4) into an a
