As one embodiment, the polishing disk 8 is internally provided with magnetic pole holes 801, the polishing disk 8 is molded by magnetic conductive materials, and each magnetic pole is fixed in the corresponding magnetic pole hole 801 by magnetic attraction. In the polishing process, the magnetorheological polishing liquid is adsorbed on the polishing disk 8, and the magnetorheological polishing liquid forms a flexible 'small grinding head' with a plastic bonding action and has rapid relative motion with the workpiece, so that the surface of the workpiece is subjected to great shearing force, and the material on the surface of the workpiece is removed, thereby achieving the polishing effect.
Preferably, a connecting screw is fixed at the center of the lower end of the iron core 2, and the polishing disk 8 is sleeved at the lower end of the iron core 2 and is in threaded connection with the connecting screw through a locking nut 4 to lock and fix the polishing disk 8. The polishing disk 8 is fixed through the lock nut 4, so that the polishing disk is convenient to assemble and disassemble and can be applied to various processing machine tools; the polishing disk 8 can be disassembled and replaced by a common grinding wheel polishing disk 8, a flannelette polishing disk 8 and a polishing wheel which are required, so that the application range is enlarged.
