Abstract: This study focuses on the abrasive buffing applications of nanofibres. Based on previous research, using the proposed three-direction physical model, the mass ratio of oil to abrasive grain and the abrasive size in abrasive machining for the same fibre mass and free volume were clarified. Furthermore, the base polishing characteristics of different-diameter fibres under different free volumes with different grain sizes and the effect of the combination of mesh size and grain size on the polished surface roughness of a workpiece were discussed. Herein, the polishing mechanism model of a nanofibre buffing pad is proposed, and using this model, the effects of grain size and number on polishing efficiency are demonstrated. The relationship between the combination of mesh size and grain size on the polished surface roughness of a workpiece and the effects of grain size and number on polishing ability are also verified.
