As-milled, bead blast, anodized, and powder coat are all finishes that are available through CNC milling.

As-milled is a finish that refers to the surface of a part or component as it appears after it has been machined. Parts and components produced through CNC milling can be left in their raw, unfinished state, which can be useful for applications where a specific finish is not required.

Bead blast is a finish that is produced by blasting the surface of a part or component with small glass beads. This can produce a rough, matte finish that is suitable for applications where a smooth surface is not required.

Anodizing is a process that involves coating the surface of a metal part or component with a layer of oxide. This can provide a hard, durable finish that is resistant to wear and corrosion.

Powder coating is a process in which a dry, powdery paint is applied to the surface of a part or component using an electrostatic charge. This can provide a durable, protective finish that is resistant to wear and corrosion.

When selecting a finish for a CNC milled part or component, it is important to consider the specific requirements of the application, as well as the properties and characteristics of the available finishes. This will help ensure that the right finish is chosen to meet the desired performance and functionality requirements.
