What are the Different Finishes that can be Applied to CNC Turned Parts?

here are many different finishes that can be applied to CNC turned parts, depending on the desired aesthetic, performance, and environmental requirements. Here are some of the most common finishes:

As-machined finish: This is the simplest and least expensive finish, and it is often used for parts that do not require a high level of precision or smoothness. The as-machined finish is achieved by simply removing the excess material from the part with the cutting tool.

Polished finish: This finish is achieved by using a series of progressively finer abrasives to smooth the surface of the part. Polished finishes are typically used for parts that need to be highly smooth and reflective, such as jewelry or medical devices.

Hardcoat anodizing: This finish is applied to aluminum parts and creates a hard, wear-resistant layer on the surface. Hardcoat anodizing is often used for parts that are exposed to harsh environments, such as marine or industrial applications.

Powder coating: This finish is applied to metal parts by electrostatically spraying a powder coating onto the surface. The powder coating is then cured in an oven, which creates a hard, durable finish. Powder coating is often used for parts that need to be corrosion-resistant or that need to be a specific color.

Brazing: This finish is applied to metal parts by melting a filler metal onto the surface. The filler metal bonds to the base metal and creates a smooth, corrosion-resistant finish. Brazing is often used for parts that need to be joined together or that need to be a specific color.

The finish that is best for a particular CNC turned part will depend on the specific requirements of the application. It is important to consult with a CNC turning serviceprovider to discuss the different options and to choose the finish that is right for your needs.
