Chemical milling

Chemical milling is a way of making things thinner by using chemicals instead of cutting with a knife or machine. It's like making your own paper thinner by dissolving some of it with water.

To do chemical milling, we start with a big piece of metal or material that we want to make thinner. We put it into a container with a special chemical that can dissolve it. The chemical will only dissolve a very thin layer of the material, so only the outside layer of the material will be dissolved away.

We can control how much of the material is dissolved away by controlling how long we leave it in the chemical bath. If we leave it in longer, more of the material will be dissolved and it will become even thinner.

This process is used in many different industries, like aerospace and electronics, because it allows manufacturers to create complex shapes and reduce the weight of parts without weakening their strength. It also saves money because they don't need to use expensive machinery to cut and shape the material.

So, think of chemical milling like magic potion that dissolves a little bit of metal to make it as thin as paper without using scissors or machines.
