Chemical Milling in Rancho Cucamonga, CA

What Is Chemical Milling?

Chemical milling, also called industrial etching or chemical machining, is a process that uses chemical baths of temperature-regulated etching chemicals to remove material from metal to produce the required shape or configuration. Chemical milling can create channels or pockets.

Chemical milling removes material through a chemical reaction. Any material not to be chemically milled first gets masked off using a maskant. After the milling, the entire piece gets stripped of the maskant and thoroughly cleaned.

• It uniforme removes metal from specific areas without altering the integrity or properties of the metal.
• It can also remove material from the entire surface of the component to reduce weight.

Chemical milling is often used in the aerospace industry to remove material from skin panels to reduce weight and create small thin metal parts of the complex design with no defects or stresses to the metal parts.

Why Use Chemical Milling?

The primary purpose of chemical milling is to reduce weight, improving the aircraft’s efficiency. The aerospace industry uses chemical milling to remove shallow layers of material from aircraft components such as airframe parts or missile skin panels or to produce blind features such as channels or pockets.
