The magnetic abrasive Finishing is magnetic abrasive particles in the magnetic field generated by the grinding pressure, and relative movement between the workpiece and the magnetic pole, and a new light on the workpiece surface finishing process. As the magnetic abrasive grains of the abrasive is an average diameter of about 150μm granular substances, large susceptibility iron powder and grinding ability of the silicon carbide, or alumina powder the mixed composite body by a certain percentage, Therefore, it is both magnetic properties and grinding capacity. Factors affecting the quality and efficiency of the magnetic abrasive Finishing the magnetic induction intensity of the processing region, the workpiece material, the surface roughness value of the former step, the machining gap, the machining time, the particle size of the magnetic abrasive grains, the component ratio and magnetic permeability can, saturation magnetic induction, fill volume, bulk density. In this thesis the magnetic abrasive finishing processing mechanism, processing, magnetic properties and applications of magnetic abrasive, and its preparation method-depth study on the theory and practice of some useful exploration. Paper using theoretical analysis and experimental testing, numerical calculation and modeling methods, from the micro and macro aspects of magnetic abrasive finishing process factors and related issues, the main research contents: 1, presents a new binder program, and prepared for the follow-up to a large number of experimental studies of the various mass ratio of the magnetic abrasive. 2, different adhesive magnetic abrasive and adhesive and sintered magnetic abrasive machining experiment, analyze the different effects on processing quality. 3, two methods to determine the the magnetic abrasive permeability performance. Adhesive magnetic abrasive, for example, studied the influence of the mass ratio of the magnetic abrasive particle size parameters of its saturation magnetic induction, the magnetic abrasive saturation magnetic induction, to provide a theoretical basis for the design of the magnetic field generating device . Adhesive magnetic abrasive particles, for example, research the magnetic abrasive bulk density, bulk density and particle size relationship model, laid the theoretical basis for determining the general scope of the bulk density of the magnetic abrasive. 5, to bond the magnetic abrasive grains, for example, the ratio in the filling amount and quality of different circumstances, magnetic abrasive Finishing machining results analyzed experimentally. In this paper, the analysis and study of magnetic abrasive preparation process, key performance indicators, as well as finishing machining process parameters to master them, and eventually applied to actual production and to further improve the quality of magnetic abrasive finishing processing to promote magnetic abrasive finishing processing technology to improve the level of China's Finishing Technology, led the development of related industries, resulting in significant social and economic benefits.
