Influence of the machine frame on the dynamic properties of spindle and tool is investigated using an example of a real machine tool. Model of the whole mechanical system is created as a coupled system of the tool, spindle and machine frame single submodels. Experimental verification of the model has shown a good match of the system critical frequencies and compliances. It has been proved that properties of the machine frame limit the dynamic properties at the tool tip especially in the case, if a compact tool is used.
