Abstract
PURPOSE: To form precision patterns without causing side etching in the stage of forming rugged patterns by a chemical etching method on the surfaces of the metallic body to be worked by etching the surface of the metallic body with an etching soln. and bringing a matrix for patterning into press contact therewith.
CONSTITUTION: The lower part of a metallic cylindrical body 3 to be formed with rugged patterns on its surface by chemical etching is dipped in an etching soln., and a matrix 1 which is formed with rugged patterns on the surface thereof and is made of a material to be unaffected by the etching solution, such as PVC, epoxy resin or the like, is kept energized to be brought into contact at all times with the body 3 and in this state both are rotated mutually in opposite directions. The surface of the body 3 is etched by the etching soln. to form an oxidized film. This film is pressed by the projecting parts of the matrix 1, by which cracks are induced and the film is broken. The parts pressed and broken by the projecting parts of the matrix upon repetition of such stages are further etched, whereby the rugged patterns reversed from those of the matrix are formed. Since no masking is used, side etching is obviated and the rugged patterns are chemically etched with high accuracy.
