CNC Machining Surface Finishes
Compare surface finish options for CNC prototypes and production parts. Select the finish to match your application, appearance and performance requirements.
As Machined

As machined finish leaves the surface straight from the CNC machine, providing a cost-effective option with tool marks.
Anodizing

Anodizing increases corrosion resistance and wear properties, while allowing for color dyeing, ideal for aluminum parts.
Polishing

Polishing achieves a high gloss finish, reducing surface roughness and enhancing the aesthetic appeal of metals.
Sand Blasting

Sand blasting uses pressurized sand or other media to clean and texture the surface, creating a uniform, matte finish.
Brushed Finish

A brushed finish creates a unidirectional satin texture, reducing the visibility of marks and scratches on the surface.
Powder Coating

Powder coating applies a thick, wear-resistant layer with excellent color and texture options, suitable for a variety of surfaces.
Electroplating

Electroplating bonds a thin metal layer onto parts, improving wear resistance, corrosion resistance, and surface conductivity.
Black Oxidize

Black oxidize is a conversion coating for ferrous metals that improves corrosion resistance and minimizes light reflection.
Electropolish

Electropolish is a chemical process that smooths and brightens surfaces while improving corrosion resistance.
Alodine

Alodine coating provides corrosion protection and improves paint adhesion, mainly used on aluminum surfaces.
Tumbling

Tumbling smooths and polishes small parts by friction and abrasion in a barrel, offering a consistent but slightly textured finish.
