MANDREL FOR ELECTROMECHANICAL MACHINING Russian patent published in 2013 - IPC B24B39/02 

Abstract RU 2471608 C1

FIELD: process engineering.

SUBSTANCE: invention relates to machine building, particularly, to mandrels for electromechanical machining of holes. Mandrel front part has isolating bush and fixture. Gaging tooth and lock nut are arranged on said fixture. Mandrel rear is external thread to support coupling nuts and current-isolating bush. Fixture is articulated to mandrel from for self-alignment in machined hole. Lock nut OD complies with that of machine hole.

EFFECT: reduced forces to be applied to mandrel, expanded machining performances, higher precision.
