Chemical Machining: Working Principle, Application ...

28/07/2020  Chemical machining is the material removal process for the production of desired shapes and dimensions. It is done by selective or overall removal of material by a controlled chemical attack with acids or alkalies. The metal is slowly converted into metallic salt by chemical reaction and is finally removed in this form.
