Aerospace CNC Machining
Aerospace CNC machining demands more than accurate parts. It demands certified quality, documented materials, and traceability you can audit, because the components we make may end up in flight-critical assemblies. At Baetro, we machine aerospace parts to AS9100 and ISO 9001 standards, with 5-axis capability, tolerances to ±0.001″, and full material traceability on every order.
We work the alloys aerospace relies on, from titanium and Inconel to high-strength aluminum 7075, and we back every part with CMM inspection and AS9102 first-article documentation. Because we manufacture direct from our certified facility in Qingdao, you get that aerospace-grade rigor at 30 to 60% below typical domestic cost, with a dedicated engineer on your program from quote to delivery.
What Is Aerospace CNC Machining?
Aerospace CNC machining is the precision manufacturing of components for aircraft, spacecraft, and defense systems. It demands tighter tolerances, stricter material controls, and more rigorous documentation than standard machining. Every part must meet AS9100 quality standards, with full traceability from raw material to finished component.
At Baetro, we specialize in 5-axis machining of aerospace alloys, including titanium, Inconel, and aluminum 7075. We hold tolerances to ±0.001", with CMM inspection and AS9102 first-article inspection reports. Our facility is AS9100 and ISO 9001 certified, ensuring every part meets the stringent requirements of the aerospace industry.
What Aerospace CNC Machining Demands
Aerospace parts are not ordinary machined components. They operate under extreme loads, temperatures, and safety requirements, so the standards around them are strict. Aerospace CNC machining is defined by four demands that go beyond typical precision work.
AS9100 Quality Systems
Aerospace buyers require a quality management system built for the industry, which is exactly what AS9100 provides. Our processes follow the International Aerospace Quality Group standards, with rigorous risk management and configuration control.
- AS9100 certified: built on ISO 9001 with aerospace-specific requirements
- Process control: first-article inspection and in-process checks ensure consistency
- Audit-ready: documentation that stands up to customer and regulatory review
Traceability & Mill Certs
Every part needs traceability back to the raw material lot, with mill certifications to prove it. We maintain full material documentation from raw stock to finished component, so you always know what went into your part.
- Material traceability: complete chain from mill lot to finished part
- Mill certifications: included with every shipment
- Alloys: titanium, Inconel, 7075 aluminum, stainless, and more
Tight, Inspected Tolerances
Critical features are inspected and recorded, not just machined and shipped. Any shop can claim precision. Aerospace machining is about proving it, consistently, with documentation that stands up to audit.
- Standard: ±0.001" (±0.025 mm) on critical features
- CMM inspection: every part verified, not assumed
- AS9102 FAI: first-article reports for production approval

Aerospace Manufacturing Reference
Aerospace favors materials with high strength-to-weight ratios and strong performance at temperature. Each machines differently, and knowing how matters as much as knowing why it is used.
| Material | Why Aerospace Uses It | Machining Notes |
|---|---|---|
| Titanium (Ti-6Al-4V) | Strength-to-weight, heat resistance | Work-hardens; needs sharp tooling, low speeds, rigid setup |
| Inconel / superalloys | Extreme high-temperature strength | Very tough to cut; slow, rigid, heavy coolant |
| Aluminum 7075 | High-strength aluminum | Machines well; great for structural brackets |
| Aluminum 6061 | Versatile, weldable | Easy to machine; general airframe parts |
| Stainless 316 | Corrosion resistance | Work-hardens; sharp tools, steady feeds |
Titanium and Inconel are where aerospace machining gets demanding. Both work-harden and resist cutting, so they punish dull tools and weak setups. Our 5-axis centers, rigid workholding, and process discipline are built for exactly these alloys.
5-Axis Capability and Tolerances
Many aerospace components have complex, contoured geometry that is hard to reach from a single direction. Our 5-axis simultaneous machining centers handle these shapes in one setup, which matters for two reasons.
5-Axis Machining Capabilities
| Axis Configuration | Typical Application | Precision | Efficiency |
|---|---|---|---|
| 3-Axis | Prismatic parts, flat faces, standard features | ±0.005" (±0.13 mm) | Multiple setups required |
| 4-Axis | Multi-sided parts, angular holes, indexed features | ±0.002"–0.005" | Fewer setups, better alignment |
| 5-Axis Simultaneous | Undercuts, deep pockets, contoured surfaces, aerostructures | ±0.001" (±0.025 mm) standard | Single setup, eliminates cumulative error |
Across our aerospace work, we hold tolerances to ±0.001" (±0.025 mm) as standard, with tighter available on request for critical features. That precision is verified, not assumed.
Why 5-Axis Matters
- Accuracy: The part is never re-fixtured and re-aligned between operations, which eliminates cumulative positioning error.
- Complex geometry: Handles undercuts, deep pockets, and contoured surfaces that are impossible or difficult on 3‑axis machines.
- Verification: Every part is inspected on CMM equipment, with AS9102 first‑article documentation available.
- Cost efficiency: Single‑setup machining reduces fixture costs, programming time, and overall lead time on complex parts.

Certifications That Qualify Us
Certifications are table stakes in aerospace, but buyers' teams deserve to know what each one actually guarantees. Here is the plain-English version.
AS9100 & ISO 9001
ISO 9001 is the baseline quality management standard used across industries. AS9100 builds on it with aerospace-specific requirements for risk management, configuration control, and product safety. It is the certification most aerospace and defense buyers require before they will even quote you, and it is the foundation of our quality system. The standard is maintained by the International Aerospace Quality Group, and our processes follow its requirements.
AS9102 First-Article Inspection
First-article inspection is the aerospace way of proving a new part is made correctly before full production. Under AS9102, we document every dimension, material, and process on the first article and verify it against your drawing. That record gives you confidence that the production run will match the approved part, and it gives your quality team the paperwork they need. The AS9102 forms and requirements are published through SAE International.
ITAR & NADCAP
ITAR governs the handling of defense-related technical data and parts, and we can support ITAR-controlled work on request. NADCAP covers special processes like heat treatment and plating. If your program requires either, talk to our team so we can align documentation and controls to your needs. For dedicated defense programs, see our defense manufacturing capabilities.
Prototype to Production, One Supplier
Aerospace buyers worry about a specific risk: qualifying a supplier for prototypes, then having to re-qualify someone new for production. That re-qualification costs time, money, and program risk. We eliminate it by handling the full lifecycle under one roof.

Design for Manufacturability in Aerospace
Good aerospace design balances performance against machinability, and small choices have a big effect on cost and lead time. Our free DFM review looks for these on every quote, but it helps to know them up front.
- Apply tight tolerances only where they matter. Over-tolerancing drives up cost and inspection time. Hold ±0.001" on critical features and use general tolerances elsewhere.
- Design for 5-axis access. Geometry a single setup can reach is faster and more accurate than shapes that need multiple fixtures.
- Simplify where you can. Fewer deep pockets, thin walls, and hard-to-reach features mean shorter cycle times and less risk.
- Pick the right alloy for the job. Titanium and Inconel cost far more to machine than aluminum, so reserve them for where their properties are truly required.
- Plan finishing early. Specifying anodizing, passivation, or plating up front avoids surprises late in the program.
- Design with these in mind. Your aerospace parts will quote lower, machine faster, and pass inspection more easily.
Frequently Asked Questions
Answers to common questions about aerospace CNC machining certifications, materials, tolerances, and production.
What certifications do aerospace machine shops need?
Most aerospace and defense buyers require AS9100, which builds on ISO 9001 with aerospace-specific quality requirements. Depending on the work, ITAR registration and NADCAP special-process accreditation may also apply. As an AS9100 machine shop with ISO 9001 certification, we can also support ITAR-controlled work on request.
What materials are used in aerospace CNC machining?
Common aerospace materials include titanium alloys like Ti-6Al-4V, nickel superalloys like Inconel for high-temperature parts, high-strength aluminum such as 7075 and 6061, and stainless steels like 316. Each is chosen for its strength-to-weight ratio and performance at temperature.
What tolerances do aerospace parts require?
Requirements vary by part, but critical aerospace features often call for ±0.001" or tighter. We hold ±0.001" (±0.025 mm) as standard, with tighter tolerances available on request, and we verify critical dimensions with CMM inspection and documented first-article reports.
Why is 5-axis machining used in aerospace?
Many aerospace components have complex, contoured geometry. 5-axis machining produces these shapes in a single setup, which improves accuracy by eliminating re-fixturing and reduces cumulative error between features. It also shortens lead time on complex parts.
What is AS9102 first-article inspection?
AS9102 is the aerospace standard for first-article inspection. It requires documenting every dimension, material, and process on the first production part and verifying it against the drawing. That record confirms the part is made correctly before full production and gives your quality team the required documentation.
How much does aerospace CNC machining cost?
Cost depends on material, complexity, tolerances, and quantity. Difficult alloys like titanium and Inconel cost more to machine than aluminum. Because we manufacture direct from our Qingdao facility, aerospace-grade quality typically runs 30 to 60% below domestic pricing. Upload your CAD file for an exact instant quote.
Can you handle both prototypes and production?
Yes. We machine low-volume aerospace prototypes and full production runs in the same AS9100 certified facility, with the same quality system and traceability. That lets you validate a design, then scale to production without re-qualifying a new supplier or changing your documentation.
