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] Other names for chemical etching include photo etching, chemical etching, photo chemical etching and photochemical machining. It is ...
The term "crystallographic etching" is synonymous with "anisotropic etching along crystal planes". However, for some non-crystal materials like glass, there are unconventional ways to etch in an anisotropic manner. [2] The authors employ multistream laminar flow that contains etching non-etching solutions to fabricate a glass groove.
Photochemical machining (PCM), also known as photochemical milling or photo etching, is a chemical milling process used to fabricate sheet metal components using a photoresist and etchants to corrosively machine away selected areas. This process emerged in the 1960s as an offshoot of the printed circuit board industry.
GFS Chemicals Inc, formerly known as G. Frederick Smith Chemical Company, [1] is a privately owned fine and specialty chemical company with headquarters in Powell, Ohio and manufacturing facilities in Columbus, Ohio. It was founded by G. Frederick Smith in Urbana, Illinois in 1924, and moved to Columbus, Ohio in 1928. [1] [2] [3]
ferric chloride may be used for etching copper or zinc plates, whereas nitric acid may be used for etching zinc or steel plates. Typical solutions are 1 part FeCl 3 to 1 part water and 1 part nitric to 3 parts water. The strength of the acid determines the speed of the etching process. The etching process is known as biting (see also spit ...
Chemical milling is an example of a specialty process that removes excess material by the use of etching chemicals and masking chemicals. There are many technologies available to cut metal, including: Manual technologies: saw, chisel, shear or snips; Machine technologies: turning, milling, drilling, grinding, sawing
