Study on the Characteristics of Simply Mixed the Magnetic Abrasives Particles

Utilize the characteristic that magnetic force line may penetrate the non-magnetic material, using the magnetic abrasive finishing (MAF) method complete to the non-magnetic small workpiece surface precise processing. In order to enhance polishing efficiency, usually with the magnetic particles and abrasive particles mixes together in the sinter method or the cementation method, the cost is higher; the variety is not also complete. Therefore, use the simply mixed method mixed the ferromagnetism iron particles, the alumina particles and the lipin, directly participates in magnetism polishing, already obtained the good processing effect through the experiment. This paper analysis and explanation the best experimental condition such as the granularity proportion of the ferromagnetism iron particles and the alumina particles etc.
