The Most Suitable Clearance in MCF (Magnetic Compound Fluid) Polishing

Abstract

Prof. Shimada has demonstrated experimentally that the polishing effect using our developed intelligent fluid, magnetic compound fluid (MCF), is greater than that using previously developed intelligent fluids, i.e., magnetic fluid (MF) and magneto-rheological fluid (MRF). Shimada succeeded in float polishing with a large clearance utilizing a newly developed magnetic responsive fluid, MCF, which was improved by the addition of a-cellulose, thereby achieving a clearance as great as 8mm. He also clarified the mechanism of the new polishing technique. A comparison of the MCF polishing effect with those of techniques using the ordinary magnetic responsive fluids, MF and MRF, showed the polishing effect of MCF to be greater than those of MF and MRF. The MCF polishing technique is applicable to many types of polishing, widening the variety of the uses of magnetic float polishing (MFP). However, while clearance to8mm is possible, this may not be the most suitable value. In this study, we clarified the most suitable value for MCF abrasion experimentally.
