CNC machining parts and prototype surface finishing
Why do you need surface treatment for CNC parts and prototypes?
1. Enhance the durability of products.
Corrosion and oxidation can easily damage the surface of a product, thereby preventing it from being used properly. Adding a coating or antioxidant layer to the surface of the product can increase its resistance to breakage.
2. Improve Product Aesthetics
For many products, especially consumer products, enhancing the appearance of the product can greatly attract customers and increase sales and market share.
What surface processing you could get from us?
Whatever surface treatment you need, our professional and skilled technicians can provide high-quality surface finishing services for your prototype and parts.
Machine parts retain the accuracy of CNC and have a short turnaround time. However, parts have visible tool marks and potentially sharp edges and burrs, which can be removed. Machined parts have a standard roughness of 3.2 μm (125 μin), but finishing can reduce the roughness to 0.4 μm (16 μin).
There are three types of polishing methods: mechanical, chemical, or electrochemical. It is a finishing process that uses polishing tools on the surface of the workpiece to achieve a shiny, flat surface. This prevents degradation of quality due to corrosion, oxidation.
Bead blasting is the process of blowing glass beads onto machined parts with a high-pressure robotic force, which adds a uniform matte or satin surface finish to the part and makes it look better.
Anodizing is an electrochemical process that adds a ceramic layer to the surface of a metal part. This layer resists corrosion and wears while adding aesthetic appeal to the product. There are two main types of anodizing: Type II (clear or colored) anodizing and Type III (hard coat) anodizing.
Electroplating is a surface treatment process that uses electrolytic chemical reactions to apply a metal film to certain metal surfaces. Specially processed plastics can also be plated. Plating can prevent oxidation, and improve wear resistance, electrical conductivity, and aesthetics.
Laser engraving is using a laser beam to shine on the surface of various materials, making the evaporation of the surface material or chemical-physical changes or burning off part of the material. And finally, the parts are etched with the desired permanent.
Pad printing is one of the characteristic printing methods. It can print various single-color, two-color or multi-color text and patterns on the surface of irregular products.
Wire drawing is a mechanical movement and chemical corrosion metal processing process on the metal surface through abrasive materials. It can form a line pattern on the surface of the workpiece to achieve a beautiful, corrosion-resistant effect.

The overview of the surface finishing
Surface treatment works by adding, altering, removing, or reforming the material surface to improve the aesthetics, material strength, corrosion resistance, and other properties of the finished product. It is mainly done by mechanical, chemical, or electrical means.
Surface finish and surface roughness are the same concepts, surface finish is another name for surface roughness.
Surface roughness is the unevenness of the machined surface with small spacing and tiny peaks and valleys.
Surface treatment refers to the alteration of the surface of a material by adding, removing, or reshaping it. The goal is to protect the material and improve the appearance of the product.
1.Product use environment
Careful consideration of the product’s use and application environment will help you make the right choice.
2. Product Durability
Durability is an important part of manufacturing.
4. Part dimensions
Machining surface finishing may change the size of the part. The surface finishing may affect the mating surfaces and clearances of parts that must be mated.
Good finishes higher quality materials.
According to the process and method, surface treatment is divided into the following 4 methods:
- Adding Materials
- Modify material
- Eliminating materials
- Rebuild materials
