The linear rolling guideway is one of the most essential parts of the machine tool. So it is very important to analyze the dynamic-static characteristic of the machine tool by considering rolling guideway for the study of the effect on machinery function. The research is based on a NC machine tool produced by a certain plant of machine tools. In this study, methods of simulating the rolling guideway support were studied; and the configuration of the spring damper elements of the bearing supports were investigated. The finite element analysis on the CKS6125 machine tool was used to confirm its dynamic characteristics. The finite element analysis models were validated by some experiments.
