Popis:	In the circumstance of the commissioning of a vertical machining lathe centre, since a previous overhaul due to operative inattention, the rolling bearing of the working table was damaged. When this damaged part was changed, a detection of the machine dynamic response by vibration measurements was also performed. An inacceptable level of vibrations was detected which negatively influences the machining quality. Although it was initially suspected that the higher level of vibrations was solely due to a combination of mechanical causes, an additional analysis performed on frequencies, showing more complex vibrational spectra, suggested a deep interaction between electronical and mechanical criticalities.
