CNC Milling Surface Finishes at our– Enhance Performance and Appearance with Expert Finishing Solutions

we offer a diverse range of surface finishing options for CNC-milled parts, tailored to improve both functional and visual properties. Whether you’re aiming to enhance surface aesthetics, increase corrosion resistance, or achieve a smoother finish, our finishing processes are designed to meet your specific requirements. Choose from a variety of metal finishing techniques to optimize durability, precision, and overall part quality.

Surface FinishDescription
As machinedStandard finish with a surface roughness of 1.6 µm (126 µin).
SmoothingThe standard smoothing surface roughness (Ra) is 0.8 µm (63 µin).
PaintingSpraying paint, pigment, or color to a solid surface as a colored protective layer.
PassivationRemove ferrous contaminants or use a light coat of protective material to create a shell.
Powder CoatingA functional and decorative finish that is applied as a free-flowing, dry powder.
AnodizingType II (anodizing color or clear) or Type III (anodizing hard coat).
PolishingProduce a smooth and shiny surface.
Black OxideForming a black conversion coating on metal parts.
Bead BlastingRemoving surface deposits by applying fine glass beads at a high pressure.
Abrasive Blasting/SandblastingSmoothing and cleaning a hard surface by forcing solid particles across that surface.
Electroplating/PlatingForm a thin coherent metal coating on an electrode.
BrushingPolishing the metal with grit resulting in a unidirectional satin finish.
Chromate Conversion CoatingIncrease the corrosion resistance while maintaining conductive properties.
