Examination and Research of the Surface Topography of Ultrasonic Vibration Honing Nd-Fe-B

The mechanism of ultrasonic vibration honing Nd-Fe-B has been briefly elaborated after the introduction of the strategic significance of processing Nd-Fe-B.Based on the formation principle of Scanning Electronic Microscope(SEM),and at the examination with the aid of SEM to the ultrasonic vibration honing Nd-Fe-B material's superficial microscopic topography,the paper discusses the new processing mechanism according to the SEM examination picture.The research indicates that as a result of supersonic high frequency vibration,the path of the abrasion extends at the same time,and the supersonic cavitation effect forms the intense shock-wave,impacting Nd-Fe-B material's internal surface,providing the supersonic energy for the superficial abrasive dust's elimination,which directly explain that the honing processing efficiency is enhanced,and the processing surface roughness is high.
