Used NDT & Inspection Equipment for Aerospace

Buying Guide: Used NDT & Inspection Equipment for Aerospace

Expert guidance for aerospace equipment buyers. 2 listings currently available.

What to Look For When Buying Used

CMMs are only as good as their calibration and thermal environment. Request the dimensional accuracy verification report (ISO 10360-2 or ASME B89.4.10) from the last 12 months showing maximum permissible error (MPE) across the measuring volume. Any CMM showing MPE outside specification needs factory recalibration — cost $8,000–$25,000 depending on machine size. Verify the probe system and qualification sphere are included — Renishaw probe heads and stylus libraries represent $5,000–$30,000 in accessories that are often stripped before equipment sales. For ultrasonic NDT equipment, check the transducer condition and ask for calibration certificates for all included transducers — expired calibration means you're buying equipment you can't use for aerospace production without recertification. Software licensing is the hidden cost in used CMM purchases: Zeiss Calypso, Brown & Sharpe PC-DMIS, and Hexagon licenses are tied to the original machine serial number, but transfer is not guaranteed — verify license transferability before purchase.

Price Ranges by Condition and Age

NDT and inspection equipment spans a wide price range by type: Bridge CMMs (small to mid-size, < 1.5m × 2m work volume): $25,000–$150,000 for units from Zeiss, Hexagon, Brown & Sharpe, or Mitutoyo with current calibration certificates. Large bridge CMMs (> 1.5m × 3m) and gantry CMMs: $80,000–$400,000 — production-scale measurement for large structural assemblies. Portable CMM arms (Romer, FARO): $15,000–$60,000 for 6- and 7-axis arms with current calibration. High portability value for field inspection work. Ultrasonic NDT systems (phased array, immersion): $20,000–$120,000 depending on channel count and software capability. X-ray and digital radiography systems: $35,000–$250,000 for portable and fixed systems. Compliance documentation (calibration certificates, equipment history, NADCAP audit records) adds 15–30% to equipment value versus identical equipment without paperwork. Software licensing for CMM post-processors can add $8,000–$25,000 to effective acquisition cost.

Top Manufacturers and Why They Matter

Zeiss (Germany) leads in CMM accuracy and software — their Calypso software is the aerospace standard for prismatic part measurement and first article inspection reporting. Service network is extensive in North America and Europe. Hexagon Manufacturing Intelligence (formerly Brown & Sharpe, Leitz, Romer) offers the broadest CMM portfolio from portable arms to large gantry systems. PC-DMIS software runs on virtually all Hexagon CMMs regardless of age. Mitutoyo builds reliable mid-tier CMMs with lower total cost of ownership — widely used in aerospace QA labs handling high-volume inspection. FARO Technologies dominates portable metrology — their Quantum Arms and laser trackers are the aerospace field inspection standard for large assembly verification. Olympus (ultrasonic and industrial videoscope systems) is the preferred brand for aerospace UT inspection. GE Sensing & Inspection Technologies provides X-ray and CT systems used for weld inspection and composite void detection. For NADCAP-qualified NDT operations, documentation of equipment calibration history and personnel qualification records from the previous facility directly supports faster re-qualification at the new site.

Common Applications in Aerospace Manufacturing

Inspection equipment supports quality assurance across every stage of aerospace manufacturing: First article inspection (FAI) — CMMs measure machined parts against engineering drawings for AS9100 first article approval. Required for every new part introduction on aerospace programs. Production statistical process control (SPC) — CMMs and vision systems track dimensional variation in production machining and forming operations. Composite NDT — ultrasonic C-scan systems map delaminations, porosity, and foreign object inclusions in cured composite panels. Required for every primary structural composite part. Weld inspection — radiographic (X-ray) and ultrasonic phased array systems verify weld quality in fuel systems, structural joints, and engine components. Assembly verification — laser trackers and photogrammetry systems verify large assembly geometry — wing attachment, fuselage join, empennage — to tolerances achievable only with optical metrology. Engine component inspection — borescopes and eddy current probes inspect turbine blades, disk bores, and compressor cases for fatigue cracking and erosion damage without disassembly.

Why Buying Used Makes Sense

Inspection and NDT equipment holds value exceptionally well in the aerospace market because the buyer pool is narrow and qualified. A used Zeiss CMM with current calibration performs identically to a new one at 40–60% of the price. The aerospace inspection cycle doesn't punish age — it rewards documentation. A 10-year-old CMM with 10 years of calibration certificates is more valuable to an AS9100-qualified buyer than a newer CMM without records, because the calibration history directly supports faster qualification into production. New high-end CMMs from Zeiss or Hexagon list at $120,000–$600,000 with 8–16 week delivery windows. Used equivalents from aerospace plant closures deliver immediately at 40–65% of new cost. Portable metrology — FARO arms and laser trackers — is the highest ROI used inspection category: instruments that list at $80,000–$180,000 new are routinely available at $25,000–$60,000 with calibration certificates from facility downsizes and technology refresh cycles.
