Our standard surface finishes

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.

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.

RequirementSpecification
Thickness8 - 12 μm (clear), 4 - 8 μm (color)
ColorBlack, clear or any RAL code or Pantone number

Anodizing hardcoat (type III)

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

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.

RequirementSpecification
Grit#100, #120 and #150
ColorUniform matte of raw material color

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.

RequirementSpecification
Thickness18 - 72μm
ColorBlack or any RAL code or Pantone number.

Electropolishing

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

RequirementSpecification
ColorNatural metal color.

Black oxide

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

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.
