Junction surface characteristics is one of the many factors influencing the performance of machine tool. It is also a major source of machine tool contact stiffness and damping. Study on the junction surface characteristics of this machine is very important to improve the performance of the machine and the machine structure optimization. According to the similarity theory, this paper will small guide rails are used as scale model, research on small rail junction surface characteristics and combining the conclusion extended to heavy machine tool surface. This paper from the geometric similarity and dynamic similarity surface on the comparative analysis of the small rail and heavy machine tool guide rail with two aspects of similarity theory, after verification, proof of small guide surface and heavy machine tool guide surface similarity.
