Wheel machining equipment is provided, including a first-stage turning system used for carrying out first-stage turning of a wheel, a high-precision connection system used for carrying out high-precision positioning conversion from first-stage turning to second-stage turning, and a second-stage turning system used for carrying out second-stage turning of the wheel. A wheel machining method is also provided.

A manufacturing cell comprises a machine tool that has a tool carrier carrying a tool unit and has two adjacent workpiece paths oriented in a longitudinal direction. The tool unit can be displaced relative to a machine bed of the machine tool in a transverse direction and in a vertical direction. At least one workpiece carriage per workpiece path can be displaced in the longitudinal direction along the machine tool. The tool unit can be displaced in the longitudinal direction relative to the machine bed and/or relative to the workpiece carriages. The tool carrier overhangs or projects beyond the workpiece paths. The individual workpiece carriage can also be displaced in the longitudinal direction along the workpiece supply. Furthermore, the workpiece supply has at least one lowerable or tiltable stop device per workpiece path.

A machining centre includes a base supporting several superposed stages. At least one stage is movable and can be position indexed relative to the base. Each stage includes distinct stations at a constant angular pitch including machining units or grippers. The combination of stations from adjacent stages defines a plurality of machining locations each combining a unit and a gripper. Each relative movement between two indexing positions of two stages changes the composition of the locations. Each gripper has at least one rotational degree of freedom relative to the stage that carries it. At least one station includes both at least one machining unit and at least one gripper.

A manufacturing cell comprises at least one workpiece path having a workpiece supply region of a workpiece supply and a workpiece table of a machine tool. The machine tool has at least two machining robots. The workpiece table comprises at least one suction block assembly. The manufacturing cell has a second workpiece path running in a longitudinal direction of the manufacturing cell and parallel to the first workpiece path, with a second workpiece table comprising at least one suction block assembly. In addition, each suction block assembly can be displaced in the longitudinal direction of the manufacturing cell. This increases the output rate of a manufacturing cell and expands its machining capabilities.
