MANUAL TOOL-ELECTRODE FOR ELECTROCHEMICAL POLISHING Russian patent published in 2008 - IPC C25F7/00 C25F3/16 

FIELD: metallurgy.

SUBSTANCE: invention concerns field of metals electromachining and can be used for manual electrochemical polishing of different products, including products with c crooked spatial surface. Tool-electrode contains body 1 of ergonomic shape made of dielectric material, with attached to it electrode plate 2, connected by means of electric contact 4 and wire 5, passing through hole with sealant 6 in bode wall 1, to negative contact of constant-current source, at that to the body 1, by means of connecting pipe 7, is connected flexible tubing 8 for electrolyte continuous feed to body hollow 1. Electrode plate 2 is made with multitude of holes, located after equal pitch, and from the outside to it is attached remote spacer 3, creating clearance between electrode plate 2 and workpiece, connected to positive contact of constant-current source. Electrode plate can be made of concave camber in the form of globe calotte or of convex camber in the form of globe calotte.

EFFECT: providing of efficient production, qualitative performing operations and achievement of surface roughness Ra 0.4...0.2, at universality, availability, low cost price and ability of manually moving of tool-electrode by any surface.
