    Dynamic characteristic of ball screw feed system in a milling machine is studied numerically in this work. In order to avoid the difficulty in determining the stiffness of rolling joints theoretically a dynamic modeling method for analyzing the feed system is discussed and a stiffness calculation method of the rolling joints is proposed based on the Hertz contact theory.
