Abstract：

A certain type high-speed CNC made by TRUMPF was studied, the structure and working principle of rotating screw punch were introduced, and the electric serew punch was analyzed based on finite element analysis. The screw punch model was simplified, and the first ten order undamped natural frequency and mode shape of screw based on model analysis were obtained by using the numerical simulation soft of ANSYS，then the correctness of modeling and analysis was verified by experiment. The results of model analysis show that the punch may be easily destroyed when excitation frequency approaches to the eighth natural frequency. As a result，the serew punch should be reinforced in the weak rigidity portion obtained by natural frequency，then the resonant response could be analyzed and the response of screw punch under the external excitation was analyzed so as to proofread the maximum speed of screw punch under the saft situation and avoid working at the resonant frequency.
