Available surface finishes for CNC machining
Surface finishes are applied after machining and can change the appearance, surface roughness, hardness and chemical resistance of the produced parts.
|As machined (Ra 3.2μm / Ra 126μin)||This is our standard finish. Parts are machined and deburred, sharp edges are chamfered.|
|Smooth machining (Ra 1.6μm / Ra 63μin)||Smooth machining is like an ‘As machined’ finish but with slightly less evident machine marks. Parts are machined at a lower feed, no hand polishing is applied.|
|Bead Blasted||Parts are bead blasted with glass beads which results in a grainy texture.|
|Brushed + Anodized type II (Glossy)||Parts are brushed and then anodized type II. Ideal for increasing the corrosion resistance of the part. Typically results in a glossy color.|
|Bead blasted + Anodized type II (Matte)||Parts are bead blasted and anodized type II. Ideal for increasing the corrosion resistance of the part. Results in naturally matte colors. For glossy colors, please select the brushed anodizing option.|
|As machined + Anodized type III (Hardcoat)||Parts are machined and an anodizing type III coating is directly applied to the surface. Ideal to improve corrosion and wear resistance of components.|
|Powder Coated||Powder coating is a strong, wear-resistant finish that is compatible with all metal materials.|
|Brushed + Electropolished (Ra 0.8μm / Ra 32μin)||Parts are brushed and electropolished. Ideal to reduce the micro-roughness of the part.|
|Black oxide||Applicable on steels, black oxide is a conversion coating used to improve corrosion resistance and minimize light reflection.|
|Chromate conversion coating||Parts are machined and a chromate conversion coating is applied. Ideal to increase the corrosion resistance of the part while maintaining its conductive properties. RoHS compliant.|
|Brushed (Ra 1.2μm / Ra 47μin)||Parts are brushed with a #400 - 600 grit. Ideal to reduce the surface roughness of the part.|
|Polishing (Ra 0.8μm / Ra 32μin)||Parts are manually polished in multiple directions. Surface is smooth and slightly reflective.|
Other surface finishes are also available. Learn more about our metal and plastic surface finishing capabilities here.
We follow ISO 2768 standards for CNC Machining.
