ELECTRODE TOOL AND METHOD OF ELECTROABRASIVE PROCESSING OF INNER SURFACE OF SEMI-CLOSED CAVITY OF PART Russian patent published in 2023 - IPC B23H5/10 B23H5/06 

FIELD: electrode tool.

SUBSTANCE: group of inventions is related to an electrode tool and a method for electroabrasive processing of the inner surface of a semi-closed cavity of a part. The electrode tool contains a flexible conductive base and a flexible current supply in the form of a conductive tension element. The conductive base is made in form of an elastic woven mesh of elastic wire elements in form of transverse and longitudinal turns of a spiral with dielectric abrasive grains on the wire elements on the processing side. The end of the conductive base on the side of the cavity neck is connected to a flexible conductive tension element having a dielectric coating, and the opposite end of the conductive base is designed to be connected to the inner surface of the semi-closed cavity of the part with a flexible dielectric rod through an elastic element and a slider made of a ferromagnetic alloy on the side of the semi-closed cavity opposite electromagnet on the outer surface of the part.

EFFECT: finishing machining by electroabrasive method is provided inside a semi-closed cavity with a variable perimeter in a part with a narrow neck for inserting an electrode tool into the semi-closed cavity and withdrawing it after completion of the processing.
