Magnetic finishing method and device thereof

Abstract

Abstract PURPOSE:To make a three-dimensionally complex-form article polishable uniformly according to the specified form, by making up a magnetic brush rotating at a high speed in space between a fixed pole and a moving pole rotating at a high speed together, while projecting a work to this magnetic brush. CONSTITUTION:When a pulley 9 locked to a shaft 19 rotates, a moving yoke 5, a nonmagnetic material ring 11, a segment magnetic pole 12 and a machining tank 13 are all solidfied in one via a nonmagnetic material disc plate 7 and rotate around yokes 2-4 and an exciting coil 1 via a bearing 8. Hereat, when the coil 1 is excited and thereby a magnetic field is formed there, magnetic abrasive grains form a powerful magnetic brush B along a line of magnetic force lying between a fixed yoke peripheral part 2a and an upper end face 12a of the segment magnetic pole 12 and rotate together with a machining tank 13 as one body. Simultaneously with this rotation, a spindle 15 holding a work 14 is projected into the magnetic brush B with the spindle rotated, and surface polishing takes place. Thus, a three-demensionally complex-form article can be polished uniformly according to the specified form.
