Photo Chemical Milling Equipment: Etchers to Strippers
Photo Chemical Milling is a process for the removal of metal by chemical action and is ideally suited for production of flat, relatively thin parts of unlimited configurations, and for other jobs requiring area, point, or line removal of metal. Chemcut revolutionized the chemical milling process in 1957 when we developed conveyorized double-sided spray etching. The new technique made the Photo
