Experimental Investigation of Polishing Character of Rotating Magnetic Polishing Fluids

Abstract:

In the face of the mechanical part of shape complex, the surface is difficult to be finished by the automatic and effective methods, but the magnetic fluid mixed with the polishing and cutting particles has motion characteristics in magnetic field. This paper introduces a kind of polishing technology which can rotate magnetic polishing fluid in the influence of magnetic field. The viscosity and hardness of magnetic polishing fluid change under the magnetic field, and the magnetic polishing fluid rotates in the fluence of the magnetic stirring apparatus, when machining magnetic in the liquid in polishing, and fixed in the liquid in proper position. When we select the best position in the magnetic polishing fluids and immerse the workpiece in the magnetic polishing fluids, the magnetic fluids rotate and move relatively to the workpiece. The friction between the magnetic fluid and the surface of workpiece has the finishing efficiency. The experiment is carried out to study the relation of the roughness and polishing and location on the home-made polishing laboratory platform in detail. The experimental results show that the rotating magnetic polishing liquid can be used for polishing the workpiece in super smooth processing, which is much better than polishing abrasive alone in reducing surface roughness. The study opens a new field for the application of the magnetic fluid. However, the direction of the field, the speed of the movement, and the polishing time of the process parameters still needs further research.
