INSTRUMENT-ELECTRODE FOR ELECTROCHEMICAL POLISHING OF CROOKED SPATIAL SURFACE Russian patent published in 2008 - IPC C25F7/00 B23H3/04 

FIELD: metallurgy.

SUBSTANCE: invention concerns area of metal electrochemical treatment and can be used for electrochemical polishing of crooked spatial surfaces. Instrument-electrode contains body 1 with cutouts located on equal spacing, at that body 1 forms chamber inside of which in alignment there are located split sleeves 3 with rod electrodes 4, which are connected to electric conductor 5 and implemented with ability of free displacement lengthwise its axis by internal surfaces of split sleeves 3 for self-adjustment by treated surface of detail. Cutouts in body 1 are through, and its chamber is filled by hydro-layer 2, and in wall of body 1 it is located binding screw 6, effecting to hydro-layer 2, staving split sleeves 3, for fixing rod electrodes 4 and fixing it with forming by them surfaces, which is retaliatory with respect to treated surfaces of detail.

EFFECT: fast formation of any crooked spatial surfaces and steady clearance between electrode and treated surface.
