DEVICE FOR FINISHING TREATMENT Russian patent published in 2009 - IPC B24B31/104 

FIELD: machine building.

SUBSTANCE: invention is related to the field of machine building and may be used for finishing treatment of parts by loose abrasive with application of alternating force field. There is rotary rotor and working chamber with technological medium installed in fixed body. Chamber is installed with the possibility of rolling due to friction contact of external surface of working chamber and internal surface of friction element secured on fixed body with provision of centrifugal-planetary motion of working chamber along cone. Rotor is arranged with openings that are located pairwise opposite to each other at the angle α_i to axis of fixed body and at the same distance R _i from rotation axis. In one of openings of mentioned pair having values α_i and R_i specified for this type of treatment, working chamber is installed, and balancing device is installed in the other opening. Inside working chamber there is replaceable chamber with openings arranged in its bottom along external diametre. System is provided for continuous flushing of process medium, having insert installed in working chamber bottom with groove along Archimedes spiral intended for removal of spent liquid through replaceable chamber openings with its displacement along groove to the center of working chamber.

EFFECT: treatment process is intensified due to provision of alternating centrifugal force field.
