The chemical milling process selectively removes material while maintaining structural strength where needed. Material weight reductions of 75 percent or more and thickness reductions down to .010" or less produce super lightweight yet strong parts. Conventional machining methods render it virtually impossible to lighten complex contour sheet metal parts with the close tolerance results of chemical milling.
