Abstract: Such characteristic parameters as static/dynamic stiffness and damping force were studied for the linear rolling guide joint of NC machine tools on a CKS6116 horizontal NC lathe. A static/dynamic characteristic test was done to obtain all dynamic parameters of the lathe, then the software ANSYS for FEA was used to simulate and display various vibration modes and natural frequencies with the guide joint parameters taken into account. In addition, a vibration excitation test was done for the whole lathe to verify the exactness of the parameters obtained from simulation. As a result, it is proved that the static/dynamic stiffness and damping force of the linear rolling guide joint affect greatly the dynamic behavior of NC machine tools.
