Abstract
An ELID honing device includes a honing toolpositioned above a workpiecehaving 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 guidepositioned in proximity to an upper portion of the workpiece to guide the honing tool to the hollow cylindrical inner surface. The honing toolhas a fixed guidehaving a predetermined radius R from the rotation axis to its outer peripheral surface, and honing stonesandhaving 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 guidehas a hollow cylindrical ELID electrodehaving an inner surfacefor guiding an outer peripheral surface of the fixed guide of the honing tool and capable of being subjected to a negative voltage.
