A type of detecting method for vibration default of precision roller grinder of cold rolling factory was introduced. Ac-cording to influence of grinding technical parameters on vibration,and assisting by detecting and FFT analysis of displacement signals and acceleration signals,frequency character of default vibration was gotten. By default classification elimination method combining frequency analysis,default reasons were found,and a correct method for default elimination and avoidance was given in end.
