Surface Finishes for CNC Machined Parts
In addition to our custom CNC machining services, we offer complete surface finishing solutions for precision machined parts. If you need a custom surface finishing solution that is not listed, please contact us and we would be honored to customize our services for you.
| Name | Description | ||
|---|---|---|---|
 | As machined | The machined aluminum parts are left with visible tool marks and potentially sharp edges and burrs, which can be removed upon request. | |
 | Bead Blasted | Give the machined parts a smooth and uniform matte surface finish, thereby removing tool marks. | |
 | Polishing | Creating a smooth and shiny surface by manually polishing in multiple directions or by applying a chemical polish treatment. | |
 | Anodizing | Type II (Anodizing color or clear) or Type III (Anodizing hard coat) Anodizing does not cover tool marks unless bead blasted beforehand. | |
 | Chromate Conversion Coating | Increase the part’s corrosion resistance while retaining its conductivity. RoHS compliant. | |
 | Decorative Chrome Plating | Enhance aesthetics and durability of the cnc aluminum components. | |
 | Powder Coat | Applying powdered paint to the components and then baking it in an oven, which results in a stronger, more wear- and corrosion-resistant layer that is more durable than traditional painting methods. | |
