Hubs manufacturing standards

CNC Machining standards

We follow ISO 2768 standards for CNC Machining.

Limits for nominal size Plastics (ISO 2768- m) Metals (ISO 2768- f)
0.5mm* to 3mm ±0.1mm ±0.05mm
Over 3mm to 6mm ±0.1mm ±0.05mm
Over 6mm to 30mm ±0.2mm ±0.1mm
Over 30mm to 120mm ±0.3mm ±0.15mm
Over 120mm to 400mm ±0.5mm ±0.2mm
Over 400mm to 1000mm ±0.8mm ±0.3mm
Over 1000mm to 2000mm ±1.2mm ±0.5mm
Over 2000mm to 4000mm ±2mm

All parts are deburred. Tightest achievable tolerance is +/-0.01mm and is dependent on part geometry.

Process Tolerance
FDM ± 0.5% with a lower limit of ± 0.5 mm (± 0.020")
SLA ± 0.5% with a lower limit of ± 0.15 mm (± 0.006")
SLS/MJF ± 0.3% with a lower limit of ± 0.3 mm (± 0.012")
Polyjet ± 0.1% with a lower limit of ± 0.1 mm (± 0.004")
DMLS ± 0.2% with a lower limit of ± 0.2 mm (± 0.008") for parts smaller than 10 mm in any dimension. ± 2% for parts over 10 mm in any dimension.

All parts are deburred. Tightest achievable tolerance is +/-0.01mm and is dependent on part geometry.

Sample Verification Program First Article Inspection

Our Sample Verification Program is a premium First Article Inspection. This is a standard procedure for all Injection Molding orders, and is available on request for CNC machining orders.

You can utilise this program to:

  • Test for fit in-house
  • Verify that our quality meets your expectations

It works as follows:

  • 2 sets of parts will be shipped to you for verification
  • Once the parts are approved, we will continue with full production

If you require any design changes, you can submit the modified models to us. Please note that any significant changes may result in an increase in price.
