Surface Finishing for CNC Machining
As Machined
The fastest finishing option. Parts are delivered with visible tool marks and may have sharp edges or burrs, which can be removed upon request. The surface typically corresponds to a 125 µin Ra finish.
Anodizing
An electrochemical coating that improves corrosion resistance and appearance.
Type II: Available in clear, black, red, gold, and more.
Type III: Thicker and harder for added wear and corrosion protection.
Alodine
A chemical conversion coating that provides corrosion resistance while maintaining electrical conductivity. Commonly used for aluminum parts requiring strong protection without altering dimensions.
Bead Blasting
Abrasive media is propelled at high pressure to create a uniform matte texture. Ideal for cosmetic parts where a smooth, non-reflective appearance is desired.
Brushing
A mechanically applied, unidirectional satin finish created using abrasive belts or pads. This process reduces surface imperfections and gives metals like aluminum and stainless steel a clean, refined look.
Black Oxide
A chemical coating applied to steel and stainless steel to create a black, corrosion-resistant surface. Often used for aesthetic appeal while offering mild protection without affecting dimensions.
Sand Blasting
Similar to bead blasting but uses sand-based abrasive material. Produces a matte, textured finish suitable for smoothing surfaces or removing imperfections.
Plating
A thin metal layer is applied to the part to improve durability, conductivity, and appearance. Creates a smooth and glossy finish while protecting against corrosion.
Painting
A coating of liquid or powdered paint is applied to achieve a smooth, glossy, or clear finish. This method can enhance appearance and provide basic environmental protection.
Polishing
A mechanical finishing process that smooths and buffs the surface to achieve a reflective, glossy appearance. Reduces surface roughness and improves overall aesthetics.
Chromate
A conversion coating that creates a matte, clear protective layer. Enhances corrosion resistance while maintaining electrical conductivity—often used for aluminum and zinc parts.
E-Coating
An electrocoating process that applies a uniform, corrosion-resistant paint layer over the entire surface of the part. Known for excellent coverage, even in hard-to-reach areas, and available in multiple colors.
