Machining centre for the mechanical processing of workpieces

A machining centre for the mechanical machining of workpieces, with a first machining unit which has a first tool slide which can be equipped with a machining tool for machining a workpiece arranged in a machining zone and is movable in a Z-axis direction of a coordinate system formed by three mutually perpendicular axis directions X, Y, Z, and a first workpiece positioning unit that can be moved in an X-axis direction and in a Y-axis direction and can be equipped with a clamping device for receiving and clamping the workpiece to be machined, wherein the first tool slide has a drive spindle which can be driven in rotation to provide drive energy for the machining tool, and wherein the clamping device is rotatable about a first axis of rotation, wherein a second machining unit is provided operable independently of the first machining unit, which is arranged adjacent to the first machining unit in the X-axis direction and has a second tool slide movable independently of the first tool slide in the Z-axis direction and a second workpiece positioning unit movable independently of the first workpiece positioning unit in the X-axis direction and the Y-axis direction.
