Chemical Milling . Immersion of a part in an etching solution to remove metal and leave a pre-determined design is the basic operation of the CHEM-MILL process. The cross-section of the finished part may show tapers, selected reduction in certain dimensions, uniform reductions in all dimensions, or a combination of these configurations.

In the chemical milling process the artwork is applied on both sides of the material and is etched from both sides to cut all the way through the material. It is a versatile manufacturing technique that retains hardness, temper, magnetic permeability, and other qualities without causing excessive stress on the material.
