CNC Milling Parts Finishes
For material and application-specific projects, we offer a comprehensive list of surface finishes, which include:
1. As Milled
Natural, regularly arranged cutting tool marks. According to the specific materials and cutting tools used, they may appear with different patterns and visual effects. The surface is quite smooth, which can achieve a Ra 0.8 ~ 1.6 µm. For non-critical or decorative parts, it’s totally usable. It’s also the most cost-effective and fast turnaround option.
2. Anodizing
We offer Type Ⅱ and Type Ⅲ for aluminum and titanium milled parts. For purposes include enhance cooriance resisance, wear resistance, and decoration(different colors available).
3. Plating
Our plating options include chrome plating, zinc plating, and nickel plating, which are typically applied to enhance visual appearance and the ability to withstand harsh environments, such as humid or seawater.
4. Powder Coating
Powder coating offers more protection for the CNC milling parts with a thick layer of plastic attached closely to the surface. This isolates the metal from the environment, preventing it from corrosion and impact. Typically, the plastics are thermosetting, such as Epoxy, Polyester, and Hybrid. We can also customise plastic powder to meet your specific needs.
4. Sand/Bead Blasting
We offer both sand and bead blasting for either deburring or surface enhancement needs.
5. Laser Engraving
For series number, part number, and brand logo etching needs, we offer laser engraving options available on the surface of different metals.
What is CNC Milling
CNC Milling, named for the “milling” process, involves the use of rotary cutting tools to remove material from a workpiece, achieving precise shapes and features. Here’s a closer look at the specifics of CNC milling:
- Why “Milling”?: The term “milling” refers to the process of grinding or cutting material with a rotating tool, which differs from turning where the part is rotated. In milling, the tool rotates at high speeds to cut materials into the desired form and dimensions.
- Characteristics of Milling: CNC milling machines can operate on multiple axes (3-axis, 4-axis, or 5-axis mills), providing versatility to create complex geometries and deep cuts with high precision. The multi-axis setup allows the machine to move the tool in various directions, offering detailed and intricate machining capabilities.
- Suitable Shapes and Parts: This process is ideal for producing parts with detailed features such as slots, holes, notches, and contours. CNC milling is highly effective for functional prototypes, engine components, and complex mechanisms, which require precise and repeatable cuts.
