This　paper　integrates　experiment　modal　analysis　and　the　analytical　modal　analysis　to　study　on　the　vibration　phenomena　occurring　occasionally　at　the　different　components　of　a　precise　horizontal　machining　centre.　The　paper　is　focused　on　extracting　the　mode　shape　of　the　major　components　of　the　machine　in　order　to　ensure　resonance　phenomena　as　a　cause　of　vibration.　At　first　the　main　natural　frequencies　with　the　corresponding　modes　of　vibration　of　the　machine　structure　are　obtained　by　the　experiment　modal　analysis.　Then　the　dynamic　behavior　of　the　machine　components　is　simulated　using　a　finite　element　simulation　model.　The　comparison　of　the　results　based　on　finite　element　calculation　with　their　experimental　counterparts　shows　the　reasonableness.　The　model　is　evaluated　and　corrected　with　experimental　results　by　modal　testing　of　the　machine　components.
