Our standard surface finishes

Here is a list of standard surface finishes. For custom surface finishes such as electroplating or polishing, please contact sales@nuoue.com.

As machined

Our standard finish is “as machined” finish. It has a surface roughness of 3.2 μm (126 μin). All sharp edges are removed and parts are deburred. Tool marks are visible.

Smoothing

A finishing CNC machining operation can be applied to the part to reduce its surface roughness. The standard smoothing surface roughness (Ra) is 1.6 μm (63 μin). This can be decreased down to 0.4 μm (15.7 μin) upon request and on a case-by-case basis. Machine marks are less evident but still visible.

Bead blasting

Bead blasting adds a uniform matte or satin surface finish on a machined part, removing the tool marks. This is used mainly for visual purposes and comes in several different grits which indicate the size of the bombarding pellets.

Requirement Specification
Grit #100, #120 and #150
Color Uniform matte of raw material color
Part masking Indicate masking requirements in technical drawing
CNC machining surface finishes Bead Blasted

Anodizing color or clear (type II)

Type II anodizing is mainly used to produce parts with a uniform, aesthetically pleasing surface and provides good corrosion and limited wear resistance.

Requirement Specification
Thickness 8 - 12 μm (clear), 4 - 8 μm (color)
Color Black, clear or any RAL code or Pantone number
Part masking Indicate masking requirements in technical drawing
CNC machining surface finishes Anodized Clear or Color type 2

Anodizing hardcoat (type III)

Type III anodizing provides excellent corrosion and wear resistance, suitable for functional applications.

Requirement Specification
Thickness 50 - 125 μm
Color Black or clear
Part masking Indicate masking requirements in technical drawing
CNC machining surface finishes Anodized Hardcoat type 3

Powder coating

Powder coating is a strong, wear-resistant finish that is compatible with all metal materials and can be combined with a bead blasting to create parts with smooth and uniform surfaces and excellent corrosion resistance.

Requirement Specification
Thickness 18 - 72μm
Color Black or any RAL code or Pantone number.
Part masking Indicate masking requirements in technical drawing
CNC machining surface finishes Powder Coated

Electropolishing

Electropolishing is an electrochemical process used to polish, passivate and deburr metal parts. It is useful to reduce surface roughness.

Requirement Specification
Color Natural metal color.
Part masking Indicate masking requirements in technical drawing

Black oxide

Black oxide is a conversion coating used to improve corrosion resistance and minimize light reflection.

Requirement Specification
Color Black.
Part masking Indicate masking requirements in technical drawing
CNC machining surface finishes Black oxide

Brushing

Brushing is produced by polishing the metal with grit resulting in a unidirectional satin finish. Not advisable for applications where corrosion resistance is required.

Requirement Specification
Surface roughness 0.8 - 1.5 μm
Grit #80-120
Part masking Indicate masking requirements in technical drawing
