chemical milling
finishing process
Also known as: deep etching
Quick Summary
Chemical milling is a finishing process that removes metal from selected or overall areas of metal parts through controlled chemical action. This method is similar to the process used for creating metal printing and engraving plates. It can be used for cutting blanks of thin metal parts or for removing metal from larger parts. Chemical milling is one of several nonconventional machining methods used when materials are too hard or brittle for traditional machining.12
