Five axis linkage CNC machine tool is a high-tech, high-precision, machine tool used for processing complex surfaces. It is one of the means to solve the machining of impellers, blades, marine propellers, heavy-duty generator rotors, turbine rotors, and large diesel engine crankshafts. Industries such as aviation, space, military, research, precision equipment, and high-precision medical equipment have significant impacts. At the end of the last century, Toshiba banned the export of precision machine tools to the Soviet Union, shocking the international community and causing the United States to lose its maritime advantage over the former Soviet Union. Five axis linkage CNC machine tools have long been listed as strategic control materials and are a major strategic tool of great significance.
