Magnetic abrasive machining is a newlydeveloped technology for super finishing machining duringthe latest decade. The magnetic abrasive materials are putinto the space between S-pole and N-pole, which areattracted by the S、N poles and the machining part, soforming a flexible“abrasive material brush”along thedirection of the magnetic line of force. Under this conditionthe machining part rotates and oscillates simultaneously,there by the burrs will be abraded and the superficial finishwill be greatly improved.In this Paper the principle of magnetic abrasive machiningis introduced; the proper geometric shape of the magneticpoles is studied; and the stress analysis of the machiningpart in the magnetic field is given.By the experiment of magnetic abrasive machining on thequenched steel external surface, some technical findingshad been achieved. They said: while having axial oscillationswith various amplitudes and frequencies or without axialoscillation, the abrasive magnitude and the roughness ofthe machined part vary with the duration of grinding.According to the testing data, the workable optimumparameters of magnetic abrasive machining is summarized,which can be used as a tentative reference in real practice.
