Abstract

See full text

An ELID honing device includes a honing tool 10 positioned above a workpiece 1 having a hollow cylindrical inner surface, and vertically movable and rotationally drivable about a vertical rotation axis while being rockably suspended from an upper end, and a honing guide 20 positioned in proximity to an upper portion of the workpiece to guide the honing tool to the hollow cylindrical inner surface. The honing tool 10 has a fixed guide 12 having a predetermined radius R from the rotation axis to its outer peripheral surface, and honing stones 14a and 14b having outer peripheral surfaces movable in parallel from a diameter-increased position outside the radius R to a diameter-reduced position inside the radius R and capable of being electrolytically dressed. Further, the honing guide 20 has a hollow cylindrical ELID electrode 22 having an inner surface 22a for guiding an outer peripheral surface of the fixed guide of the honing tool and capable of being subjected to a negative voltage.
