Aerospace Components
Precision CNC machining for aerospace components on German Hermle 5-axis centers — titanium, Inconel and high-temperature alloys, held to ±0.002 mm on critical features and verified on a Zeiss CORTORA CMM before they ship. From one-off prototypes to production runs, we support the full range of our CNC machining services. In partnership with eVTOL enterprises since 2020, we machine flight-critical hardware that has to perform on the first part — and on every part.
Aerospace Parts We Machine
We machine aerospace parts every day — not just standard geometries, but the thin-walled, close-tolerance features that aircraft and UAV hardware demands. Since 2020 our machining has supported eVTOL enterprises on flight-critical structures and housings.
Housings & Enclosures
Motor housings, electronics enclosures and casing-style parts machined from billet to close-tolerance fits.
Structural Brackets & Fittings
Mounting brackets, lugs and fittings that carry real structural load — not just hold tolerance.
Impellers & Flow Components
Impellers, vanes and flow bodies whose geometry holds under rotation — verified on CMM, not eyeballed.
UAV & Aircraft Lightweight Structures
Thin-wall aluminum structures and frames for UAV and aircraft platforms where every gram counts.
Actuator & Mechanism Parts
Actuator housings, gear and linkage components with repeatable positioning and controlled backlash.
Avionics & Sensor Components
Precision enclosures, mounts and instrument parts for avionics and sensing packages.

Aerospace CNC Machining Capabilities
| Capability | Equipment & Specification |
|---|---|
| 5-Axis Machining Centers | 9 units — German Hermle C22U / C42U / C42UMT / C52UMT / C62UMT (×8) + Swiss Mikron (+GF+) MILL E 500U (×1) |

| 3/4-Axis Machining Centers | Japan FANUC ×16 · Taiwan Hartford ×23 · Korea Doosan ×5 · Kejie ×5 |
| CNC Lathes | Japan OKUMA / Takisawa ×20 |
| Critical-Feature Tolerance | ±0.002 mm on 5-axis critical features (machine rated) |
| Quoted Tolerance | Designed feature-by-feature — ±0.002 mm where the part demands it, cost-optimized everywhere else |
| Inspection | German Zeiss CORTORA CMM 12/18/8 RDS (0.001 mm) ×2 · Hexagon absolute measuring arm (0.006 mm) · VMS-3020G vision system ×2 · full gage suite |
| Outgoing Inspection | 100% inspection on every shipment — inspection reports, FAI and CoC available; PPAP on request |
| On-Time Delivery | 98% |
| Minimum Order | No MOQ — from a single prototype piece |
What these numbers mean
±0.002 mm is only half the story. Every critical feature is verified on a Zeiss CORTORA CMM with 0.001 mm resolution, and 100% of shipments pass through final inspection before leaving the floor. That tolerance-to-verification loop is what aerospace buyers are really purchasing.

Aerospace Components — Frequently Asked Questions
Straight answers to the questions buyers ask before sending a drawing.
What aerospace materials can you machine?
We provide aerospace CNC machining for titanium (Ti-6Al-4V / TC4, TA2), Inconel 625 and 718, 7075 and 7050 aluminum, 303/304/316 stainless steel, PEEK, POM, PEI, and ABS. Material specifications are controlled according to project requirements, with AMS/ASTM-compliant materials and material certificates available upon request.
What tolerances can you achieve on aerospace parts?
Our 5-axis aerospace machining capability can achieve ±0.002 mm on critical features, with dimensional verification using a ZEISS CMM with 0.001 mm resolution. Machining tolerances are controlled against the requirements specified on your engineering drawings, with inspection results documented as part of our quality process.
Are you AS9100 certified for aerospace machining?
Yes. We are AS9100D certified for aerospace and defense manufacturing and undergo independent audits. We also hold IATF 16949, ISO 9001, and ISO 13485 certifications. Our quality management system covers production control, inspection, documentation, and traceability. Certificates are available upon request.
Do you have a minimum order quantity for aerospace CNC machining?
No minimum order quantity (MOQ). We support aerospace CNC machining from single prototypes and low-volume production to full production runs. Each project follows defined engineering, production, inspection, and documentation procedures regardless of order volume.
What quality documents do you provide for aerospace parts?
We provide quality documentation according to project and customer requirements, including inspection reports, First Article Inspection (FAI) reports, and Certificates of Conformance (CoC). PPAP and other quality documentation can also be prepared when required by your program.
Can you machine prototype aerospace parts?
Yes. We support single-piece aerospace prototypes, low-volume builds, and production parts. Our engineers review your drawings or 3D CAD models before production, including manufacturability and tolerance requirements. We can provide DFM feedback and a quotation within 24–48 hours. Once approved, the job proceeds through our controlled production and inspection process.
How do you ensure material and aerospace part traceability?
We maintain traceability throughout the aerospace CNC machining process, from incoming material inspection through first-piece inspection, in-process inspection, final inspection, and shipment. Material lot information, production records, inspection results, and quality documentation are linked to the corresponding order. This allows each aerospace component to be traced back to its material lot and inspection history.
