Types of Finishes Avaiable for Our CNC Machining Services
As finished
CNC parts are cleaned and deburred, leaving milling and tool marks visible. The default surface finish is Ra 125 microinches, with no extra treatments.
Anodized
Anodizing is an electrochemical process that creates a clear, durable oxide layer on metal surfaces, improving corrosion resistance and appearance.
Bead Blasting
Bead blasting creates a smooth matte or satin finish by spraying the surface with fine abrasive particles, removing tool marks for a clean and attractive look.
Polishing
Polishing creates a smooth, shiny mirror finish on metal surfaces and can control material precisely, usually between 0.0001 and 0.0025 inches.
Powder Coating
Powder coating applies a colored powder to the surface, then heats it to create a tough, protective layer with strong wear and corrosion resistance and a smooth finish.
Heat Treatment
If not strict with a surface finish, heat treatments can alter the surface hardness and durability of the part, preparing it for demanding applications.
Brushing
Brushing produces a uniform, linear texture on the surface, giving it a sleek and modern appearance. It is commonly used for decorative purposes.
Chem Film
This process creates a thin, corrosion-resistant film on the metal surface without significantly altering its dimensions. It is often used for aluminum and magnesium parts.
