Such as high-end CNC systemfor five axis CNC machine tools, can also be used for high precision machiningcomplex curved surface, more suitable for more complex high-grade,advanced mold processing and automobile parts, aircraft structure, precisionmachining of complex parts. At present, five axis NC machine tool system is the only way to solve the impeller, blade, marine propeller, heavy-duty generator rotor, turbine rotor, large diesel engine crankshaft machining etc.. This paper describes the application characteristics, the cradle type machining center, five axis machine status and importance of the future, and introduces the working principle and key technology of five axis machine. Then, the whole structure of reasonable Mazak five axis machine, respectively for thecomponent systems were designed, produced the assembly drawing, part drawing, schematic and design specifications and design documents. Finally,A/C rotary axis of five axis machine were analysed and checked, detailedcalculation shows that, the A/C rotary axis is designed to meet
