Enabling New Technologies Through Metal Etching Applications; 508-478-2025; pei@photofabrication.com; Menu. Chemical machining. Chemical Machining (CHM) • Chemical Machining (CHM) was developed based on the observation that chemicals attack metals and etch them by using chemical dissolutions. Electrochemical machining works on the Faraday law of electrolysis which state that if two electrode are placed in a container which is filled with a conductive liquid or electrolyte and high ampere DC voltage applied across them, metal can be depleted form the anode (Positive terminal) and plated on the cathode (Negative terminal).
