The surface finishing of CNC parts is mainly used to enhance appearance, improve corrosion resistance, and increase wear resistance. Below are common surface coating methods for CNC parts:
🔹 Common Surface Finishing Processes for CNC Parts:
Spray Painting – Suitable for aluminum, stainless steel, etc., providing various color options.
Powder Coating – Forms a thick, wear-resistant, and corrosion-resistant layer, commonly used for industrial parts.
Anodizing + Coloring – Mainly used for aluminum alloys to enhance hardness and provide different colors.
Plating – Such as nickel plating and chrome plating, improving corrosion resistance and conductivity.
Baking Paint – Suitable for precision parts, offering a uniform and durable surface coating.
UV Coating – Provides high gloss and is suitable for high-end electronics or automotive parts.
Brushed Finish + Clear Coat – Used for metal surfaces to retain the metallic texture.
PVD Coating (Physical Vapor Deposition) – High-end decorative coatings such as gold, black, or rainbow colors.
🔹 How to Choose the Right Surface Finish for CNC Parts?
✅ Functional Requirements (e.g., corrosion resistance, wear resistance)
✅ Aesthetic Needs (e.g., color, glossiness)
✅ Cost Consideration (powder coating is cost-effective, while PVD is more expensive)
✅ Industry Application (medical and aerospace industries require stricter surface treatment)
