Chemical Milling

Photo Chemical Milling

  • What is Chemical milling?

    • Chemical milling is the process of removing metal by chemical etching and is ideally suited for the production of flat, relatively thin parts of unlimited configurations.
    • Chemical milling is also known as metal etching, photo etching, and stainless steel etching.

    Why should a metal fabrication shop have photo chemical milling capabilities?

    • Accurate and Complex
        • Metal etching has the capability to make extremely complex and accurate metal components. Since all the features are being machined at the same time the complexity can be endless.
    • Bur-Free and Stress-Free
        • Since the etching process is a chemical machining instead of mechanical machining the components will be bur free, stress-free, and will maintain all its original metal properties.
    • Fast Prototyping and Quick Design Changes
        • Metal etching has a digital tooling process that allows etcher owners to make fast changes to component designs.
    • Endless Metal Options
        • Below is a list of metals that Chemcut has built chemical etchers for in the past.
