  • Patent number: 4326933
    Abstract: Flat metallic varnish-coated metal stampings or laminations to be deburred are conveyed by contiguous vertically aligned pairs of horizontal rollers across the top of a plurality of deburring cells or vats which are continuously overflowing with an electrolyte. Alternate cells are equipped with positively and negatively charged electrodes. The electrolyte is continuously supplied to each of the cells at a rate such that the electrolyte overflows the lips of each cell over which the lamination approaches and retreats from the cell. In this manner, the top surface of the electrolyte is maintained above the top surface of the lamination so that the electrolyte inundates at least the burrs on the edges of the lamination. Current flow from each positive electrode through the electrolyte, the stamped burred edges of the laminations and to the negative electrode causing the burrs on the laminations to be removed by anodic action.
