Popis:	Vibration characteristic of mechanical system is the main factor affecting machine tool accuracy and longevity. The HTM50200 CNC with eight axles and double five-axis linkage was tested by a self-made vibration test system. The dynamic characteristic and fault diagnosis was analyzed by using the method of cepstrum identification on the vibration signal of X, Y, Z direction of the principal axis front. Analysis shows that the machining center has good dynamic characteristics, and has no obvious potential problems; the machining center is greatly influenced by Spindle cutter handle system; obtain the optimal processing parameters for machining center.
