Surface Finishes

Surface finishes are crucial for achieving the desired functional or aesthetic quality of CNC machined components. At SogaWorks, we offer a spectrum of surface finishes that enhance the aesthetics and functionality of your custom projects.

anodized aluminum parts

Grow a thickness oxide layer ranging from 0.0001 to 0.001 inches to protect and color aluminum CNC machined parts for corrosion resistance and aesthetics.

Anodizing Type II

Create a thicker layer ranging from 0.001 to 0.004 inches. it is ideal for where hardness and wear resistance are crucial.

Anodizing Type III

Preserve or enhance the electrical conductivity of the aluminum parts while still providing the benefits of traditional type II.

Conductive Anodizing Type II

Cover a part with a thin layer of metal by electrochemical deposition for function, decoration or corrosion resistance.


Apply a protective coating of zinc to steel, iron, and copper objects to prevent corrosion.


Apply a protective or functional coating to surfaces. It involves the application of liquid paint and then undergoes a curing process to solidify the paint film.


Apply a protective and decorative coating to materials, primarily metals. It involves applying a dry powder onto a surface, which is then applied electrostatically and cured under heat or UV light.

Powder Coating

Spray silica sand to the surface of the workpiece using compressed air to clean, smooth, or texture surfaces, providing a desired finish for functional or aesthetic purposes.

Sand Blasting

Apply images, patterns, or text to surfaces.

Silk Screen

A conversion coating applied to ferrous metals to provide a thin, protective layer of black iron oxide.

Black Oxide

Use abrasive belts or roller brushes to refine and improve the surface quality of components.


Selectively remove material from the surface, resulting in a smooth, polished, and often corrosion-resistant finish.

FAQs About CNC Machining Service

CNC machining is a subtractive manufacturing process that typically uses a computer program to control cutting tools, remove layers of material from a workpiece, and produce custom-designed parts.

The expense associated with our CNC machining service is variable and directly influenced by the distinct attributes of your project, including its design and tolerance specifications. The machining duration for the chosen material is another key determinant of the cost.

We cater to both one-off prototype and large-scale production runs. Thus, there is typically no strict MOQ. Whether you need a single part or thousands, We aims to provide a solution.

Lead times could change depending on the chosen material, the degree of design complexity. For smaller items specifically, CNC machining’s speed is one of its benefits. Machining times may be rather fast after the setup is finished. Parts delivered as fast as 2 day! For a more precise estimate, nevertheless, it is advisable to ask for quotations straight forwardly.
