Research on Vibratory Behavior Assessment and Maintenance of Drilling and Threading Machine VA20A

Vibrations due to mechanical defects,are transmitted within the entire structure of the equipment, are amplified during its dynamical operation, having a direct impact on the accuracy of the processed surfaces. Spectral components need vibration analysis is required. In order to determine the operation state and the vibration level caused by the mechanical failures , the FFT (Fast Fourier Transform Method) method has been used. The vibrations measurements is repeated at constant intervals; It specify the measured vibration limits; It compares the values in ISO-sites exist for determining optimal predictive maintenance intervals.
