Custom Aerospace CNC Components | Precision Machined Parts for Satellite, Defense & Airframe

Direct answer: VOLCRIX manufactures custom aerospace CNC components — including satellite defense dual use cnc machined parts such as structural components and gimbal housing — from aluminum (6061-T6, 7075-T6), titanium (Grade 2 / Grade 5), stainless steel (17-4PH, 303, 304), and engineering plastics. Parts are machined to ±0.01 mm with full traceability from mill cert to final FAI report. Whether you are sourcing a flight-qualified bracket for a low-earth-orbit constellation, a gimbal housing for a stabilized EO payload, or a build-to-print airframe fitting, the same workflow applies: DFM review, controlled machining, in-process CMM inspection, and AS9100-grade documentation. We have run aerospace programs continuously since 1991 from our Wenzhou facility, shipping to primes, Tier-1s, and direct satellite integrators across North America, Europe, and Israel.

Common Applications

• Satellite structural components and gimbal housings. Aluminum 7075-T6 and 6061-T1 brackets, sensor mounts, and antenna gimbal housings machined for low-earth-orbit constellations and EO/IR payloads. Typical envelope 30–250 mm, ±0.02 mm positional tolerance, surface treatment per MIL-DTL-16232 or chromate-free passivation.
• Defense and dual-use airframe fittings. Titanium Grade 5 and 17-4PH H1024 condition fittings, clevises, and hinge bodies for unmanned platforms and tactical systems. Parts meet AS9100D traceability with full heat-lot and mill cert capture.
• Avionics enclosures and RF shielding cans. Machined aluminum housings with internal EMI shielding pockets for flight-control units, navigation modules, and radar front-ends. Tight flatness and surface-finish controls support gasket compression.
• UAV frame and payload structures. Lightweight machined aluminum and carbon-filled PEEK components for fixed-wing and multirotor airframes, gimbals, and sensor pods — typically optimized for stiffness-to-weight ratio.

Manufacturing Support from VOLCRIX

• Material sourcing with full mill cert. We stock 7075-T6, 6061-T6, 2024-T3, Ti Grade 2 / 5, 17-4PH H1024 / H900, 303, 304, plus PEEK, PPS, and Delrin. Every bar carries a traceable mill certificate; no secondary-market dealers for aerospace work.
• DFM review against aerospace drawing notes. GD&T callouts, datum schemes, surface-finish requirements, and “critical feature” or “no substitute material” notes are reviewed against our process capability before any quote is issued.
• Star Swiss turning and 4-axis VMC. 60 Star Swiss machines (SB-16R, SR-20R, SR-32JII) handle cylindrical features to ±0.01 mm OD. For housings, brackets, and gimbal structures, we run Brother R650X1, Haas VF-2, and a 4-axis Doosan DNM 400 with 4th-axis trunnion.
• In-process CMM and FAI reporting. Every aerospace batch is verified on a Zeiss Contura CMM (1.9 µm accuracy) with full FAI reports, material certs, and process records packaged per AS9100D. First Article Inspection Reports ship in AS9102 format or your customer-specific template.
• Surface treatment coordination. Chromate conversion coating (MIL-DTL-5541), anodizing (Type II / Type III per MIL-A-8625), passivation (ASTM A967), nickel / cadmium plating, and dry-film lubricant — routed through Wenzhou-qualified partners with full process certs. Masking and prep done in-house.

Custom Aerospace CNC Components Buyer Checklist

• Mark all “critical features”, “no substitute material”, and “flight-grade” requirements in the drawing. These notes dictate material condition, traceability, and inspection scope. We hold tighter process capability on flight-critical features than the drawing tolerance implies.
• Confirm whether surface treatment is included or supplied by the customer. Chromate, anodize, passivation, and plating each have masking requirements. A bracket with one masked face changes cosmetic acceptance criteria.
• Specify datum scheme and GD&T clearly. We machine to your datums, not ours. If the drawing uses a 3-2-1 scheme with MMC or RMB modifiers, send the model with the datums applied so we can fixture correctly the first time.
• For defense and dual-use parts, flag any ITAR or export-control markers early. We do not currently hold an ITAR registration, so for parts subject to US ITAR we either route through a US-domestic partner or work on the technical-data-only side with the prime holding the export-controlled information.

Frequently Asked Questions

Can VOLCRIX produce satellite defense dual use cnc machined parts including structural components and gimbal housing?

Yes. We routinely machine structural components and gimbal housings for satellite and defense programs from 7075-T6, 6061-T6, Ti Grade 5, and 17-4PH. Typical work includes antenna gimbal housings, sensor-mount brackets, RF shielding enclosures, and structural fittings. We hold ±0.01 mm on critical features, run full FAI per AS9102 format, and ship with mill certs and process records. We do not currently hold AS9100D certification or ITAR registration; if your program requires either, we flag it during the RFQ.

What tolerances can VOLCRIX hold on aerospace CNC components?

Standard machined tolerances are ±0.01 mm on OD and ID features, ±0.02 mm on linear dimensions, and ±0.01 mm on critical-to-function features when the drawing allows. Surface finishes to Ra 0.4 µm are routine on turned and ground features. We hold these on production parts, not just on a single golden sample — process capability (Cpk) data is available on request for established programs.

What aerospace materials does VOLCRIX stock and machine regularly?

Aluminum 6061-T6, 7075-T6, 2024-T3, 5052; titanium Grade 2 and Grade 5; stainless 17-4PH (H900 / H1024 / H1075), 303, 304, 316; Inconel 718 on request; engineering plastics including PEEK, PPS, Delrin, and Torlon. Every aerospace shipment leaves with the original mill cert and our incoming-material spectrometer check on file.

Do you supply First Article Inspection Reports for aerospace CNC parts?

Yes. We issue FAI reports in AS9102 format by default, with material certs, process records, surface-finish logs, and CMM reports attached. Customer-specific FAI templates are used when required; we ask for the template at RFQ time so we can build the inspection plan around it. Reports are signed off by our quality engineer and archived per program for the duration of the production run plus 7 years.

What is the typical lead time for prototype aerospace CNC components?

Prototype aerospace parts ship in 7–15 working days from PO, depending on material availability, surface treatment routing, and inspection scope. Production orders run 3–4 weeks after tooling or fixture approval. We do not cut aerospace lead times to chase a delivery date — if a date is not real, we say so at the quote stage and propose a workable alternative.

Can you handle small-batch and low-volume aerospace production, not just prototypes?

Yes. A meaningful share of our aerospace work runs in volumes from 50 to 2,000 pieces per year — flight spares, sustainment orders, and small-lot production runs for established platforms. We hold fixture and process documentation per part number so repeat orders do not restart from scratch.
