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 treatment after machining can change the appearance, surface roughness, hardness, and chemical resistance of the parts produced.
As machined (Ra 3.2μm / Ra 126μin)
As printed MJF parts are typically gray in color and have a smooth surface, without visible layers, and a powder texture.
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.

Fine machining (Ra 0.8μm / Ra 32μin)
Finer-looking machining obtained either through higher-precision machines, lower feeds, sharper tools, or a combination of all the above. Machining marks are less evident.
Polishing (Ra 0.8μm / Ra 32μin)
Parts are manually polished in multiple directions. Surface is smooth and slightly reflective.
Electroless Nickel Plating
Parts are machined to Ra1.6µm and electroless nickel plated. Ideal for wear abrasion and corrosion resistance, not for cosmetic purposes.
Bead Blasted + Anodized type II (Glossy)
Parts are bead blasted, anodized type II and bright dipped. Results in glossy color. Ideal for cosmetic parts needing an increase in corrosion resistance.
As machined + Anodized type II
Parts are anodized (type II) directly after machining. The most cost-effective anodizing option; ideal for non-cosmetic, functional parts. Used to improve wear and corrosion resistance.
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.
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 bead blasted + glossy anodizing option.
Bead blasted
Parts are bead blasted with glass beads which results in a grainy texture and reduced machining marks.
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.
Tolerances
We follow ISO 2768 standards for CNC Machining.
Limits for nominal size | Plastics (ISO 2768- m) | Metals (ISO 2768- f) |
|---|---|---|
Over 1000mm to 2000mm | ±1.2mm | ±0.5mm |
Over 400mm to 1000mm | ±0.8mm | ±0.3mm |
Over 120mm to 400mm | ±0.5mm | ±0.2mm |
Over 30mm to 120mm | ±0.3mm | ±0.15mm |
Over 6mm to 30mm | ±0.2mm | ±0.1mm |
Over 3mm to 6mm | ±0.1mm | ±0.05mm |
0.5mm* to 3mm | ±0.1mm | ±0.05mm |
