HomeSurface Finishing Service: Process & How Does it Work
Surface finishing is the process of utilizing different techniques to alter the surface of an object.
Surface finishing is a broad range of industrial processes that alter the surface of a manufactured item to achieve a certain property, Finishing processes may be employed to improve appearance, adhesion or wettability, solderability, corrosion resistance, tarnish resistance, chemical resistance, wear resistance, hardness, modify electrical conductivity, remove burrs and other surface flaws, and control the surface friction.
Surface finishing processes can be categorized by how they affect the workpiece:
- Removing or reshaping finishing
- Adding or altering finishing
Benefits of Metal Surface Finishing Process
The functions of metal surface treatment can be summarized as follows:
- Improve the appearance
- Add specific beautiful colors
- Change the luster
- Enhance chemical resistance
- Increase wear resistance
- Limit effects of corrosion
- Reduce friction
- Remove surface defects
- Cleaning the parts
- Serve as a primer coat
- Adjust the sizes
Different Types of Metal Finishes - Metal Surface Finishing Services Available at Tuofa
Do you want your CNC parts to be more corrosion-resistant or get a specific look? Here are the introductions to different types of metal finishes, more details please feel free to contact us.

Tuofa Precision Machining Shop of Surface Finishing Capabilities
Here is a list of standard surface finishes. For custom surface finishes such as electroplating or polishing, please contact.
Machining parts, as-machined
Tuofa, as the CNC machining manufacturer you need, 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.

Anodizing
Anodizing is an electrolytic passivation process that grows the natural oxide layer on aluminum parts for protection from wear and corrosion, as well as for cosmetic effects. We are better than the most 3D printing parts manufacturers.

Powder Coating
Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light. Take a look on our metal stamping services.
