Abstract
A method and an apparatus for clearing burrs from products fabricated from metal stock. The burr of a product is used as one electrode, and another electrode is formed by extending an electrode material along, and apart from, the burr. A voltage is applied across the electrode to generate an arc between them. In the meanwhile, a magnetic field having a magnetic flux flow crossing the arc is formed to drive the arc along the burr by an electromagnetic force whereby the burr is melted and removed from the product.
