The effect of the main design parameters on the dynamic characteristics of the principal axis system is discussed by caculating natural requency and the swing at cutting point.

In this paper, in view of the working condition of common principal axes and the exothermic situation, the uneven and steady temperature field of the principal axis system during the working process is described.

Based on the function structure of principal axis system of cutting tube machine, the dynamics model of principal axis system of the cutting tube machine is build, and then the dynamic simulation for equilibrium and running stability of the system is conducted by employing MATLAB/SIMULINK.
