Chemical deburring system with a soluble mask

Abstract From the Canadian patent

A process for chemically deburring a workpiece comprising the steps of: coating the workpiece with a soluble masking material, allowing the masking material to pull away from sharp projections on the workpiece such as burrs or edges, so that the sharp projections are thinly coated or not coated, exposing the coated workpiece to a corrosive solution so that the thinly coated or not coated sharp projections are chemically attacked by the corrosive solution, and stopping the chemical attack of the corrosive colution. These steps may be repeated, as necessary, until the sharp projections or burrs are removed or edges are sufficiently milled.
