Revealing of spindle units defects by vibroacoustic methods

Abstract

Results of the research of machine tools spindle units are showed. Questions of supports defects diagnostics are considered on the basis of the analysis of vibroacoustic signal registered on the spindle unit’s case. Methods of revealing of various defects on the basis of spectral processing of signals, constructions of envelope, the analysis of hodographs and oscillatory movements trajectories are offered.
