Finishing Options Suitable for CNC Machined Parts

As finishes for CNC machined parts, there are numerous finishing options to create various aesthetics and features while including the desired performance characteristics. The selection of finishing option is based upon the nature of part material, its purpose and appearance expected thereof. Here are some common finishing options for CNC machined parts:
Anodizing: Suitable for aluminum parts, delivers corrosion protection and color variants.
Plating: It provides an additional metal layer for better visual appearance and corrosion protection.
Powder Coating: Durable finish available in different colors, meant for metal and plastic surfaces.
Painting: Flexible for customization and security.
Polishing: Polishes and improves the visual appearance of metal parts.
Bead Blasting: Ensures perfection and produces matte/textured surfaces.
Passivation: It strengthens corrosion resistance on stainless steel parts.
Electropolishing: Makes a shiny finish on stainless steel with increased anti-corrosive properties.
Laser Marking/Engraving: Adds permanent markings or information.
Chemical Treatments: Provides particular finishes or coating for parts.
The other options to consider for finishing your CNC machined parts are based on the material, functional requirements, appearance and possibly certain industry standards or regulations that may apply in your case. It is often the case of juggling between beauty, functionality and cost efficiency.
