CNC Milling Surface Finishing

CNC Milling Parts surface finish is critical to a successful part design and it is used for aesthetic and functional reasons in injection molded parts for engineering products. The surface finish improves the look and the feel of a product as the perceived value and quality of the product increase with a suitable surface finish.

Different grades of surface finishing chart.



Material Compatibility




As Machined

For as machined all sharp edges are removed and parts are deburred. Tool marks are visible.

All plastics and metals

Uniform matte of raw material color



A finishing CNC machining operation can be applied to the part to reduce its surface roughness. Machine marks are less evident but still visible.

All plastics and metals

Uniform matte of raw material color


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.

All metals

Uniform 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.

All metals

Black or any RAL code or Pantone number


Anodizing Color(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.

Aluminum alloys

Black, 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.

Aluminum alloys

Black or clear



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

All metals

Natural metal color


Black Oxide

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

Stainless steel and copper alloys



Chromate Conversion Coating (Alodine/Chemfilm)

Chromate conversion coating is used to increase the corrosion resistance of metal alloys while maintaining their conductive properties.

Aluminum and copper alloys

Clear or yellow



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

All metals

Natural metal color
