CNC lathe

CNC turning machines are able to provide low cost parts for simple cylindrical geometries. Live tooling is available for more complex geometries and is assessed on a case by case basis.

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.

  Name Description
As-machined As machined (Ra 3.2μm / Ra 126μin) This is our standard finish. Parts are machined and deburred, sharp edges are chamfered.
cnc-surface-smoothed 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 blasting Bead Blasted Parts are bead blasted with glass beads which results in a grainy texture.
Brushed + Anodizing type II (Glossy) 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) 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.
Anodized type III (Hardcoat) 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 Coated Powder coating is a strong, wear-resistant finish that is compatible with all metal materials.
brushed-electropolished Brushed + Electropolished (Ra 0.8μm / Ra 32μin) Parts are brushed and electropolished. Ideal to reduce the micro-roughness of the part.
Black oxide Black oxide Applicable on steels, black oxide is a conversion coating used to improve corrosion resistance and minimize light reflection.
Chromate Conversion Coating (Alodine) 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 Brushed (Ra 1.2μm / Ra 47μin) Parts are brushed with a #400 - 600 grit. Ideal to reduce the surface roughness of the part.
hand-polishing-photo 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.
