Anodizing
Anodized surface treatment is mostly used for CNC aluminum components. This surface treatment serves as abrasion resistance, insulation, decoration, and protection to components.
Electroplating
This surface treatment involves attaching the metal film to the metal surface using electrolysis. Thus, preventing the component from corrosion and abrasion. It also enhances the component’s appearance, light reflection, and conductivity.
Powder Coating
It involves spraying the powder coating using powder spraying equipment to the CNC component. Powder coating provides rich color, high gloss, lower cost, environment protection, and protection against defects.
Brushing
The brushing surface finish process includes forming a line pattern to the component. It can be categorized into corrugated brushing, swirling pattern, straight-line brushing, chaotic pattern brushing, and more. Brushing surface treatment is commonly used for stainless steel CNC components.

For CNC plastic components that are transparent and clear, a diamond tool is also essential to produce the machined part with an outstanding final polishing effect.
It is important that customers must think about the factors in choosing the right materials.
By considering these factors, customers are able to reap the advantage provided by CNC components.
There are five aspects on how to select the best material:
1. Know where your component is installed.
The first step for material selection is to know what your CNC component will be used for.
If you’re going to use a CNC component in an outdoor environment, you need a rust-resistant, stronger material.
Your material selection matters if your part complies with FDA-regulated specifications for nuclear, aerospace, military, or sanitation usage.
Finally, the dimensional tolerance, stress load, and fastening type be it bolted, riveted, or welded, will also be considered.
2. Consider the operating temperatures of your facility.
Temperatures that are very low or very high will restrict you from utilizing specific types of materials.
Ranging temperatures can cause parts to fold, expand, or break.
Choose the materials that are suitable for your facility’s operating environment.
Whether they are strong and stable, or volatile to allow temperature range bit.
3. Consider how material weight affects the entire design
Heavy materials provide decent strength and absorb stress.
They must not be always a “go-to” especially for applications and weight-sensitive products.
There are various lightweight materials like polymers, specialty alloys, and ceramics.
These materials provide adequate strength, capabilities, and tolerance.
However, selecting lightweight materials is difficult because there’s one specific material that will exceed your product requirements.
In the design process, considering the weight will matter.
So that you can choose the necessary material characteristics that help you to select the right lightweight materials.
4. Material strength
You need to think about the required strength profile of your final CNC machined component.
Strength refers to the weight-bearing load part that materials can handle.
There are many ways that the strong ability of the material can be divided.
Listed below are the four strength characteristics to consider when choosing a material for the machine:
- Tensile Strength: the material is resistant to break under tension.
- Endurance Strength: the cyclic stress amplitude that is applied to a material without failure.
- Wear Resistance: the ability of the materials to handle recurring and frictional loads with exhausting.
- Material Hardness: this strength characteristic expresses as a Rockwell or Brinell hardness number. It is the ability of a material to resist pinpoint surface loads.
5. Cost of overall project and material manufacturability
Lightweight, high-strength materials are commonly more expensive to root.
Also, machining resistant materials like carbide and titanium.
Keeping costs low is an advantage.
You may need to choose the materials that can meet temperature, strength, and fitment requirements.
However, it may be difficult because of your final CNC machines component needs.
It will become easier when you minimize the non-negotiable material properties your item design demands.
Considering these factors can ease the burden that mostly comes with selecting the right materials.
As well as the cost-effective material for your CNC machined components.
