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 consider rolling guideway and to study the effect on machinery function. The paper’s research is based on a NC machine tool produced by a certain plant of machine tools. Methods of simulating the rolling guideway support are studied, and the configuration of the spring damper elements of the bearing supports are also studied, and the finite element analysis on the CKS6125 machine tool has been made to confirm its dynamic characteristics. Then the finite element analysis models are validated by some experiments.
