Five-axis linkage machining center has the characteristics of high efficiency and high precision. The workpiece can be processed with pentahedron by one clamping. It can also process complex space surfaces with high precision. This machine tool system has a decisive influence on a country's aviation, aerospace, military, scientific research, precision instruments, high-precision medical equipment and other industries. At present, five-axis linkage CNC machine tool system is the only means to solve the machining of impeller, blade, marine propeller, heavy-duty generator rotor, steam turbine rotor, large diesel engine crankshaft, etc.
