Chemical Milling

Chemical Milling Line

Chemical Milling is used to etch different sizes and configurations of a variety of machined components within very specific tolerances. The chemical milling process is an efficient and economical step in the manufacturing of critical components. This is achieved by immersing intricate components in a series of chemical baths covering the complex profile. The material is reduced evenly in all dimensions. This alleviates some or all of the need for designing special tooling to get into awkward corners. Obviously the control parameters in such an operation are critical.

There are five key criteria; the concentration of the solution, it's temperature, additive dosing volumes, the time the parts are in process and the agitation of the solution. The chemical milling process consists of highly dangerous chemistries including but not limited to Hydrofluoric Acid, Hydrochloric Acid, Nitric Acid, Sodium Hydroxide and Deionized water at boiling temperatures. This chemical makeup requires an abundance of Personal Protective Equipment (PPE) including respirators, rubber boots, aprons, safety glasses and splash shields. Air emission compliance can be largely obtained by utilizing a Wet Scrubber ventilation system such as a hedron, phaser or omni.
