Photo Chemical Machining, also known as Photo Etching, is a chemical milling process used to produce highly complex, thin metal parts with intricate details that cannot be obtained via other machining methods. The photo etching process utilizes etchants to dissolve away unwanted portions of metal, so the process does not affect the temper of the raw material. When performed by an experienced photo etching company, chemical etching is able to custom machine flat sheets of metal quickly, accurately and cost-effectively.
