  • Chemical milling - WikiMili, The Free Encyclopedia

    Chemical milling or industrial etching is the subtractive manufacturing process of using baths of temperature-regulated etching chemicals to remove material to create an object with the desired shape. 1 2 It is mostly used on metals, though other materials are increasingly important. It was developed from armor-decorating and printing etching processes developed during the Renaissance

  • Chemical Machining | Working Principle, Application ...

    2 Chemical milling sometimes called Chem milling or contour machining or etching. It is used to produce shapes by selective or overall removal of metal parts from relatively large surface areas. The main purpose is to achieve shallow but complex profiles, reduction in weight by removing unwanted material from the surface as in the skin of an ...
