Abstract
A method for laser carving of paint on an outer surface of a vehicle wheel includes a step of priming: priming an outer surface of the wheel to form a painted surface; a step of laser carving: carving the primer from a selected area of the wheel by laser to remove the painted surface from the selected area, the selected area having an exposed area with metallic luster, and a step of fine-polish: polishing the outer surface of the wheel to form a fine-polished area at the exposed area. The painted surface on the wheel can be quickly removed to disclose a selected area with metallic luster, while the wheel is prevented from corrosion so as to reduce manufacturing cost and increase precision.
