Abstract-The mechanism of ultrasonic vibration honing Nd-Fe- B has been briefly elaborated after the introduction of the strategic significan ce of processing Nd-Fe-B. Based on the formation principle of Scanning Electro nic Microscope (SEM), and at the examination with the aid of SEM to the ultrason ic vibration honing Nd-Fe-B material′s superficial microscopic topography, th e paper discusses the new processing mechanism according to the SEM examination picture. The research indicates that as a result of supersonic high frequency vi bration, the path of the abrasion extends at the same time, and the supersonic c avitation effect forms the intense shock-wave, impacting Nd-Fe-B material’s internal surface, providing the supersonic energy for the superficial abrasive d ust′s elimination, which directly explain that the honing processing efficiency is enhanced, and the processing surface roughness is high.
Key words-SEM; ultrasonic processing; honing; Nd-Fe-B ; ultrasonic cavitation
