It provides an effective solution for the high-precision machining and manufacturing of large and complex structural parts. It has been successfully applied in aerospace, rail transportation, automobile manufacturing and other fields such as high-precision drilling and milling, spatial thick plate friction stir welding and high-precision assembly. Although some existing hybrid robots have high machining accuracy, the machining stroke of the robot body is limited, and they need to be processed in conjunction with a sliding base.
