surface grinding vibrations

According to the roughness test, the roughness of ultrasonic vibration-assisted grinding is better than that of conventional grinding, and the increase in amplitude has a significant effect on the improvement of roughness. When the amplitude increases from 3μm to 9μm, the surface roughness is improved about 38.1%.

The surface roughness of Ra and Rz was reduced by 14.5% and 20.6%, respectively, during the UVA-ELID grinding. The surface morphology was dramatically changed with the help of ultrasonic vibration. In a word, for nanocomposite ceramic, the UVA-ELID grinding can significantly improve surface performance and achieve a better machining effect.

The lower surface roughness value (R a: 0.118 µm and R z: 0.671) and uniform surface profile such as smooth tips of peak and valley portion was obtained in the case of ultrasonic vibration assisted dry grinding. This happens due to discontinuous shearing, ploughing, and rubbing action on the ground surface with the help of ultrasonic vibration.

surface finish, tolerances or accuracies. Depending on the circumstances, it should be noted that a machine could be both a source and recipient of unwanted vibration. For example, a surface grinder is generally a vibration-sensitive piece of equipment that needs to be protected from floor vibrations. However, as the surface grinder reverses
