The finishing pressure has an important effect on the removal rate in the process of Magnetic Float Polishing. In this paper the pressure was measured using a dynamometer and the relationship between the pressure and the finishing characteristics was analyzed. The results were summarized as follows. (1)The magnetic field lowered the transient high pressure at the beginning of the polishing, and kept the finishing pressure constant during all polishing time. (2) The finishing pressure influenced to the finishing characteristics strongly, and the characteristics were elevated by the higher pressure. (3) The changes of the finishing characteristics under the conditions of the parameters such as the volumetric concentration ratio of abrasives, the vertical polishing position, the grain size and the work speed could be explained by the changes of the strength of magnetic field gradient or the volume of effective abrasives under the workpiece.
