We machine production parts for Wind Energy Components customers, from single prototypes through to repeat batches of tens of thousands. Typical work covers blade root inserts, pitch system parts and yaw bearing housings, usually in 4140 or Ductile iron.
What makes Wind Energy Components different from general machining is not the geometry — it is the documentation and the failure modes. The parts that come back are the ones where fatigue life is the governing design case, over 20 years was not designed out at the start.
Parts we machine for Wind Energy Components
- Blade root inserts
- Pitch system parts
- Yaw bearing housings
- Nacelle fittings
Materials we run for Wind Energy Components
- 4140
- Ductile iron
- 316L
- Aluminium
Standards and documentation
- IEC 61400, DNV GL certification, GL guidelines
Tell us which standard applies and which documents you need with the shipment. Dimensional reports, material certificates, certificates of conformity and first article inspection reports are all available, and it is much cheaper to agree them before the batch runs than to reconstruct them afterwards.
Where Wind Energy Components projects usually go wrong
- Fatigue life is the governing design case, over 20 years
- Very large parts push machine envelope limits
Tolerance and finish we hold
| Requirement | Typical capability |
|---|---|
| General tolerance | +/-0.05 mm; fatigue-critical surfaces require Ra 0.8 um or better |
| Surface finish | Ra 0.4 to 3.2 um |
| Material certification | EN 10204 3.1 on request |
| Inspection | Dimensional report, CMM report, FAIR |
| Packaging | VCI and desiccant for steel, individual wrap for cosmetic faces |
Frequently asked questions
Do you have experience with Wind Energy Components parts?
Yes. Typical parts we run are blade root inserts and pitch system parts. We can share the process route and inspection approach for a comparable part before you commit.
Which materials do you recommend for Wind Energy Components?
4140, Ductile iron, 316L, Aluminium. The right choice depends on which of corrosion, weight, strength and cost is the binding constraint, and we will say so plainly rather than quoting the most expensive option.
What documentation do you provide?
A dimensional report and a certificate of conformity as standard. Material certificates, CMM reports, FAIR and PPAP submissions are available when your quality system requires them.
What tolerances do you hold for Wind Energy Components parts?
+/-0.05 mm; fatigue-critical surfaces require Ra 0.8 um or better is typical for the industry. Tighter tolerance on individual features is possible and is quoted against the specific feature rather than the whole part.
