CNC Machining Surface Finishes
With over ten different surface finishes available, our extensive selection enables you to find the perfect finish for your project, enhancing both aesthetics and functionality. Whatever your vision may be, we have the expertise to bring it to life.
As Machined
Finishing Method: 5-Axis CNC process itself
Description: The surface directly after machining, with visible tool marks
Key Advantages: Typically used for functional parts where aesthetics are not critical.
Polishing / Buffing
Finishing Method: Mechanical Finishing (Abrasive Methods)
Description: A method of using progressively finer abrasives to achieve a shiny, reflective mirror surface.
Key Advantages: Can be done chemically or mechanically, often used on metals like stainless steel and aluminum, easy to clean and anti-fingerprint.
Sand Blasting
Finishing Method: Abrasive Blasting
Description: High-pressure airflow sprays fine abrasive media to strip tool marks, forming uniform matte frosted texture.
Key Advantages: Evens out surface defects, improves adhesion for subsequent coating/anodizing, uniform low-gloss appearance.
Anodizing
Finishing Method: Electrochemical Oxidation
Description: Builds a hard protective aluminum oxide film on aluminum surface, supports dyeing into multiple colors.
Key Advantages: Great corrosion & wear resistance, thin coating without losing dimensional tolerance, customizable color options.
Powder Coating
Finishing Method: Electrostatic Powder Spraying + High-Temperature Curing
Description: Dry plastic powder is electrostatically adsorbed then baked into a thick solid protective coating.
Key Advantages: Ultra durable anti-scratch & anti-rust layer, rich matte/gloss color choices, eco-friendly with low VOC emission.
Chrome/Nickel Plating
Finishing Method: Electroplating Deposition
Description: Electrochemically deposit a thin layer of chromium, nickel or other metal onto workpiece surface.
