Sensing the vibrations of grinding wheels by contact and non-contact methods

Abstract

This study explores vibration diagnostics and balancing techniques for grinding wheels using non-contact measurement technologies. It focuses on the impact of static balancing on vibration reduction, measured with a laser interferometer for high-frequency resolution. Theoretical foundations of technical diagnostics and the application of FFT (Fast Fourier Transform) for vibration analysis are discussed. Contact and non-contact methods are compared, with experimental data demonstrating the superior accuracy of non-contact approaches. Results confirm that proper balancing enhances operational stability and extends tool life. The study highlights the benefits of non-contact diagnostics for predictive maintenance and improved reliability in industrial rotating equipment.
