Available surface finishes for CNC machining

Surface finishes are applied after machining and can change the appearance, surface roughness, hardness and chemical resistance of the produced parts.

Name Description
CNC machining surface finishes As Machined standard As Machined (standard) ~125 RA µin (3.2 RA µm). Minor tool marks will be visible on the part.
CNC machining surface finishes Smoothed Smoothed Parts are machined at a lower feed rate in order to achieve a surface roughness of ~62.5 RA µin (1.6 RA µm). Surface roughness can be decreased up to ~32 RA µin (0.8RAµm) upon request.
CNC machining surface finishes Bead Blasted Bead Blasted Bead blasting adds a uniform matte or satin surface finish on a machined part, removing all tool marks. Mainly used for aesthetic purposes.
CNC machining surface finishes Anodized Clear or Color type 2 Anodized Clear or Color (type II) Anodizing adds a thin, hard, non-conductive ceramic coating on the surface of aluminum parts, increasing their corrosion and wear resistance. Available in a variety of colors.
CNC machining surface finishes Anodized Hardcoat type 3 Anodized Hardcoat (type III) Hardcoat anodizing produces a thicker ceramic coating providing excellent corrosion and wear resistance. for functional applications.
CNC machining surface finishes Powder Coated Powder Coated Powder coating adds a thin layer of strong, wear and corrosion resistant protective polymer paint on the surface of a part. Available in a large range of colors.
CNC machining surface finishes Electropolished Electropolished Electropolishing is an electrochemical process used to polish, passivate and deburr metal parts. It is useful to reduce surface surface roughness.
CNC machining surface finishes Black oxide Black oxide Black oxide is a conversion coating used to improve corrosion resistance and minimize light reflection.
CNC machining surface finishes Brushing Brushing Brushing is produced by polishing the metal with grit resulting in a unidirectional satin finish.

Other surface finishes are also available. Learn more about our metal and plastic surface finishing capabilities here.


The table below summarizes the standard tolerances of the parts produced by certified Nuoue Manufacturing Partners. Tolerances up to .0008” (0.020mm) are available upon request.

Part size / Dimension Tolerance Angularity
< 12’’ (300 mm) ± .005’’ (0.125 mm) ± 0.5°
< 24’’ (600 mm) ± .010’’ (0.250 mm) ± 1.0°
< 36’’ (900 mm) ± 1/64’’ (0.400 mm) ± 1.0°

Tightest tolerance: ±.0008’’ (0.020 mm) Tighter tolerances are examined on a case by case basis with your technical drawings.
