ABSTRACT:
A method of finishing of ferromagnetic articles by means of ferromagnetic abrasive powders in a magnetic field formed by electromagnets of opposite polarities, wherein a ferromagnetic abrasive powder and a ferromagnetic article are first magnetized to the saturation induction, then the ferromagnetic article is placed into an external magnetic field so as to form a working gap between said ferromagnetic article and the poles of electromagnets, the total magnetic field produced therein being the sum of the external magnetic field and the field of said magnetized ferromagnetic articles. The ferromagnetic powder is finally introduced into the working gap to form a cutting "brush" and the article and the external magnetic field are brought into relative motion.
