A Magnetic Abrasive Finishing Process with an Auxiliary Magnetic Machining Tool for the Internal Surface Finishing of a Thick-Walled Tube

This paper proposes a novel magnetic abrasive finishing (MAF) process that uses an auxiliary machining tool for the internal surface of thick-walled tube. The and external poles form closed field circuit. Thus, stronger force can be generated during process. In current study, we focus on analyzing distribution flux density investigating characteristics mixed speed relative revolutions. Based characteristics, also conduct stage-by-stage by changing combinations quality was mainly evaluated measured roundness roughness. experimental results show roughness Ra are affected when total amount WA iron powder is too much; better could obtained difference in revolutions considerable, but worst. Furthermore, original measurement 270 µm reach 10 µm, increase from 4.1 to nm after 105 min
