A multifunctional stone-processing center with function of eight-five axis cooperation control relates to a stone machining center. The special-shaped stone processing center adopts the structure of a movable gantry. Gantry beams are positioned on both sides of a beam support by a steel positioning guide rail and a steel horizontal guide rail. The gantry beams are provided with horizontal sliding saddles, which are mounted on the beam by the steel positioning guide rail and the steel horizontal guide rail. The horizontal sliding saddle is provided with a vertical sliding saddle, which is connected with a working head part by the positioning of a feed shaft and the horizontal sliding saddle. The working head part is hung on the vertical beam by a rotary pair consisting of journal bearings. A horizontal rotary working station and a T-shaped working station are arranged under the beam respectively. The center with a CNC system of eight-five axis cooperation control separates the process into five different modules to complete the processing of various special-shaped stones.
