The work presents a new technology for the assembly of ball guideway systems which involves the use of a thin layer of special casting compound (EPY resin) used mainly for stable seating of machinery, especially on steel or concrete foundations. The paper presents results of simulation investigations. Simulation model was built using results of static tests. The results of simulation dynamic tests in the form of frequency response functions are shown. Experimentally supported simulation research presented in the work indicates that the use of EPY resin between the guide rail and the bed of the machine tool positively influences the dynamics of the system. The comparison of the new solution with the one used so far was performed on the basis of a guideway combination consisting of a body and a milling table. The dynamics was compared with the use of a frequency response function obtained using an impulse test. The proposed solutions are characterized by higher dynamic stiffness, which may directly influence the precision of the machined surfaces.
