ABSTRACT:
A method for surface finishing of non-magnetic articles by means of ferromagnetic abrasive powders in a magnetic field, wherein ferromagnetic powder is introduced into the magnetic field produced by oppositely positioned unlike poles of a magnetic system to form a cutting "brush" of the ferromagnetic abrasisve powder and non-magnetic articles are then placed into said magnetic field, said articles being moved relative to the cutting "brush" of the ferromagnetic powder. Additionally, each pair of non-magnetic articles is separated by a ferromagnetic body, the latter being moved relative to the cutting "brush" of the ferromagnetic abrasive powder so as to restore the cutttng "brush".
