Magnetic Fluids are colloidal dispersions of subdomain ferromagnetic particles in various kinds of carrier liquids. When magnetic fluid is placed in magnetic field gradient, it is attracted towards the higher magnetic field side. if a nonmagnetic substance is immersed in magnetic fluid, it is discharged relatively to lower field side. Magnetic Float Polishing makes an application of the magnetic buoyant levitational force. In this process the revolving workpiece is pressed to the nonmagnetic abrasives floating on the magnetic fluid.In this project the development of high-efficiency finishing machine by Magnetic Float Polishing was performed. From the series of investigations, the following points have been clarified.1) Either magnetic abrasives or nonmagnetic abrasives suspending in magnetic fluid must be used in order to apply magnetic field.2) Finishing abilities in Magnetic Float Polishing were affected by the magnetic field gradient, the viscosity of the compound or the affinity between abrasives and magnetic fluid.3) Permanent magnets are desirable to use in the finishing machine, because permanent magnets have stronger magnetic field strength than electric magnets.4) The process which the compound on the magnetic fluid was used as a lapping abrasives has better finishing abilities than Magnetic Float Polishing.

磁性流体是各种载体液体中亚域铁磁颗粒的胶体分散体。将磁性流体放置在磁场梯度中时，将其吸引到更高的磁场侧。如果将非磁性物质浸入磁性流体中，则将其相对放置在较低的侧面。磁性浮动抛光使磁性浮力悬浮力的应用。在此过程中，旋转工件被压在磁性流体上的非磁性磨料。在此项目中，通过磁性浮动抛光进行了高效效率装饰机的开发。从一系列调查中，已经阐明了以下几点。1）必须使用磁性磨料或悬浮在磁性流体中的非磁性磨蚀剂以应用磁场。2）2）在磁场抛光剂中饰面能力受磁场梯度的影响，化合物的粘度或磨料与磁性流体之间的亲和力。3）永久磁铁可在修饰机中使用，因为永久磁体的磁场强度比电气磁铁具有更强的磁场强度。4）4）化合物在磁性上的过程与磁性浮动抛光相比，将流体用作打磨的磨料具有更好的饰面能力。
