Precision Machining for the Aerospace and Aeronautics Industry
In the aerospace industry, there is no margin for error. An out-of-tolerance part means a line stoppage — or worse. This isn’t just a saying. It’s the daily reality of aerospace production teams. Tolerances are tight, materials are difficult, deadlines are constrained — and non-conformance is never an acceptable option.
This is precisely why aerospace OEMs choose certified machine shops equipped with the equipment and expertise to work under these conditions. At G.M. Précision, we are AS9100D certified — the world’s benchmark standard for aerospace quality — in addition to our ISO 9001:2015 certification.
AS9100D Certification: Much More Than a Badge
The AS9100D standard is the aerospace equivalent of ISO 9001 — but with significantly higher requirements. It covers not only the quality management system, but also risk management, configuration control, nonconformance handling, and full traceability throughout the manufacturing process.
In practice, being AS9100D certified means every order is carried out within a rigorous, audited framework:
- Manufacturing processes are documented, validated, and tracked.
- Nonconformances are detected, recorded, and handled through a formal process.
- Traceability is ensured from raw material to delivery.
- Deviations are analyzed to prevent recurrence.
- Customer and regulatory requirements are built in from the planning stage.
For an aerospace OEM, working with an AS9100D-certified shop is a guarantee of process — not just a promise of quality.
What This Means for You in Practice
Beyond certification, here’s what G.M. Précision implements on every aerospace project:
✔ Micron-level tolerances on complex parts
✔ 5-axis machining for geometries otherwise impossible to achieve
✔ Systematic CMM inspection on every critical part
✔ Full traceability from raw material to delivery
✔ Mastered materials: aerospace-grade aluminum, titanium, Inconel
Our shop runs until 2 a.m. on weekdays to meet your production deadlines. This isn’t a minor detail: in a context where the slightest delay can shut down an assembly line, the ability to deliver on time is just as critical as dimensional compliance.
Aerospace Materials: Mastery and Specifics
The aerospace industry requires some of the most difficult-to-machine materials in the industry. Each demands specific mastery of cutting parameters, tooling, and machining strategies.
Aerospace aluminum (2024, 6061, 7075, 7068): Exceptional strength-to-weight ratio, but sensitive to deformation and vibration during machining. Ideal for structures, housings, and onboard components.
Titanium (Grade 5 / Ti-6Al-4V): Very low thermal conductivity and a tendency toward work-hardening — machining titanium requires specific tooling, controlled cutting speeds, and proper lubrication.
Inconel and superalloys (718, 625): Exceptional materials for high-temperature environments (combustion chambers, turbines, heat exchangers). Among the most demanding materials to machine.
Stainless and specialty steels: For structural components, fastening assemblies, and fatigue-loaded parts.
Mastery of these materials isn’t acquired in a few weeks. It builds up order after order, through dedicated tooling, validated parameters, and a careful reading of technical specifications.
5-Axis Machining and CMM Inspection: Two Non-Negotiable Requirements
Many aerospace parts feature complex geometries — compound curves, deep pockets, multiple draft angles — that cannot be properly machined in 3 axes. 5-axis machining allows the part and tool to be oriented simultaneously, reducing the number of setups, eliminating repositioning errors, and reaching geometries otherwise inaccessible. For an OEM, this translates directly into: fewer operations, better repeatability, and tolerances that are easier to hold.
CMM Inspection
The coordinate measuring machine (CMM) is the reference tool for dimensional inspection of complex parts. It verifies dimensions and geometric tolerances (GD&T) that conventional instruments cannot reach: true positions, profiles, coaxialities, cylindricities.
At G.M. Précision, CMM inspection is systematic on every critical part. Results are documented and provided with delivery. This isn’t an extra — it’s the standard.
Types of Aerospace Projects Handled by G.M. Précision
Our shop works across a wide spectrum of aerospace projects:
- Onboard structural parts: brackets, ribs, flanges, housings, crossmembers in aluminum or titanium, machined to drawing tolerances.
- Mechanical system components: shafts, axles, gears, bushings, actuation mechanisms.
- Propulsion and thermal parts: components in Inconel or superalloy for high-temperature environments.
- Prototypes and development parts: for validation phases before series production, without dedicated tooling.
- Maintenance parts (MRO): single-unit or very small-batch manufacturing for in-service support.
Every project is approached with the same rigor: complete drawing review, identification of critical dimensions, machining process planning, and proactive communication in case of any questions or constraints.
What Aerospace OEMs Expect From a Machining Subcontractor
Expectations from the aerospace sector toward machining subcontractors are well established:
- AS9100D certification: an entry requirement for most Tier 1 and Tier 2 OEMs.
- Rigorous documentation: material certificates, CMM reports, nonconformance reports, full traceability.
- Responsiveness: the ability to respond quickly to urgent requests without compromising ongoing orders.
- Technical transparency: flagging potential issues before starting production, proposing alternatives when necessary.
- Repeatability: guaranteeing the same quality part after part, batch after batch.
These criteria are not secondary — they are the baseline conditions for a lasting partnership in this sector.
GM Précision Can Meet Every Requirement
The aerospace industry demands the best of precision machining: micron-level tolerances, difficult materials, total traceability, and flawless documentation rigor. In this context, AS9100D certification isn’t a competitive advantage — it’s the price of entry.
At G.M. Précision, we’ve built our shop and our processes to meet these requirements. Whether you’re a Tier 1 supplier, a systems integrator, or a start-up in development, we’re able to work at the right scale — with the level of quality you’re entitled to expect.
