Surface Finishing

When it comes to CNC machined parts, achieving the desired surface finish is essential for both aesthetics and functionality. Surface finishing processes are used to improve the appearance, texture, and performance of CNC machined parts. We provide various surface finishes.

Types of surface finishes

We also offer various surface finishes for CNC metal parts. These finishes can enhance the appearance and functionality of the parts, as well as protect them from wear and corrosion.

as-machined parts


This is the natural finish produced by CNC machining, without any additional post-processing. It has visible tool marks and slight roughness on the surface.

anodized aluminum parts

Anodized Finish

Anodizing is a surface treatment process commonly used for aluminum CNC machined parts. It involves creating a protective oxide layer on the surface of the part through an electrochemical process.

black oxide aluminum parts

Black oxide

A chemical process that creates a black oxide layer on the surface of the metal, providing corrosion resistance and enhancing the appearance of the part.

brushing parts


Brushed finishes are created by brushing the surface with abrasive materials to create a uniform pattern of fine lines for aesthetic purposes.

polished CNC parts


Polishing involves smoothing and shining the surface of CNC machined parts. It is typically achieved using abrasive materials, such as polishing compounds or diamond pastes, along with rotating polishing wheels or pads.

bead blasted parts

Bead blasted

This process uses fine glass beads or other abrasive materials to blast the surface, resulting in a uniform matte texture.

power coated parts

Powder coated

Dry powder is sprayed onto the surface and then baked, resulting in a durable and uniform coating.

Electroless Nickel Plating parts

Electroless Nickel Plating

Nickel-phosphorus alloy is deposited onto the surface of the metal, providing increased hardness, wear resistance, and corrosion resistance.
