Provided a full-automatic wheel hub feeding-blanking system for intelligent production line of automotive wheel hubs, comprising: an intelligent material rack and a robot; the intelligent material rack comprises a bracket assembly, a turntable assembly and a bearing seat assembly; the turntable assembly being rotatable is mounted on the bearing seat assembly; the bracket assembly mounted on the turntable assembly comprises a base provided with at least one group of lifting devices, and each the group comprises three the lifting devices, and each of which an automotive wheel hub supporting plate assembly is provided on, central axis of the three automotive wheel hub supporting plate assemblies forming the angle of 120 degrees; the robot being mounted on one side of the intelligent material rack and comprises a robotic arm, and a manipulator is mounted on the robotic arm, and the manipulator is used for clamping the automotive wheel hub.

A machine tool system includes: a machine tool that includes an openable door configured to block an opening of a cover surrounding the machine tool, and a door driving unit configured to open and close the door; and a work exchange device configured to exchange a work disposed in the cover. Further, the machine tool system includes: a first opening width setting unit configured to set a door opening width of the door; a second opening width setting unit configured to set a turnback opening width; and a door control unit configured to control the door driving unit to move the door in an opening direction from a completely closed position of the door to a position of the turnback opening width of the door, then move the door in a closing direction and stop the door at a position of the door opening width.

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 adjacent station (1, 2, 3, 4).
