Aerospace CNC Machining — Flight-critical parts to ±0.001 mm
Ginwate is a Tier-2/Tier-3 CNC machining supplier to Airbus, Boeing, Embraer, Leonardo, Safran, and HAL subcontractors. We deliver titanium, Inconel, and high-strength aluminum parts with full material traceability, AS9102 First Article Inspection reports, and EN 9100-compliant documentation.
What aerospace structural and propulsion sub-suppliers actually need
The pain points we hear from real customers in this segment — sorted by frequency. If two or more of these resonate with you, we should talk.
Zero-defect tolerance under FAA / EASA scrutiny
A single out-of-spec part can ground an aircraft, void an airworthiness certificate, or trigger a costly customer rework cycle. Aerospace buyers cannot afford a 'mostly good' supplier.
Material traceability from melt to part
Every component must trace back to its melt lot, with full certifications matching the customer's drawing-called material spec. Lost or ambiguous documentation kills the order.
Complex 5-axis geometry on hard materials
Titanium Ti-6Al-4V and Inconel 718 are notoriously difficult to machine. Tool wear, work-hardening, and deflection all compound on aerospace tolerances ±0.005 mm or tighter.
Tight delivery windows from prototype to qualification
MRO and program teams cannot wait 12 weeks for prototype iterations. Tooling delays cascade through the production schedule.
Cost pressure vs. Western suppliers without quality compromise
China sourcing must beat Western pricing by 30-50% to justify the supply chain risk — but only if quality, paperwork, and on-time delivery match a domestic Tier-1 supplier.
Export-control and ITAR-sensitive documentation handling
Customers need confidence that their CAD files, BOMs, and process documentation are handled per ITAR/EAR rules, including controlled access and non-disclosure enforcement.
How we solve those problems
Direct mapping from challenge → capability. Every claim verifiable.
18 DMG MORI / Mazak 5-axis centers + 8 wire EDM machines
Real capacity for complex titanium and Inconel geometry. We run aerospace work in dedicated cells with controlled coolant temperature and zero contamination risk between jobs.
Full EN 10204 3.1 material certification standard
Every aerospace order includes melt-lot traceability, chemical composition analysis, mechanical properties (UTS, yield, elongation), and heat treatment records. AS9102 FAI reports on first production run.
EN 9100 / AS9100-compliant process documentation
We can supply documentation packages that match AS9100 quality management requirements — internal audits, calibration records, non-conformance tracking, supplier rating data. We're not AS9100-certified ourselves but our Tier-1 customers' audits have validated the process maturity.
Counterfeit parts prevention per AS5553
Material sourced only from named primary mills (RTI, ATI, VSMPO for titanium; PCC Metals for Inconel). Full chain-of-custody. No 'mystery metal' from secondary brokers.
Engineering review on every quote
A dedicated aerospace engineering reviewer flags DFM concerns, suggests alternate processes, and validates that the print is producible at the target tolerance before quote. No surprises after PO.
Controlled IP environment
Dedicated server with access logging for aerospace CAD files. Drawings supplied to machine operators with material list, BOM, and customer name redacted. NDA on file before any technical detail exchange.
Materials we work with for this industry
Titanium Ti-6Al-4V (Grade 5)
Workhorse aerospace alloy — high strength-to-weight, corrosion resistance, fatigue resistance up to 400°C. Used for structural brackets, fasteners, hydraulic components.
Titanium Ti-6Al-4V ELI (Grade 23)
Lower interstitial content for fracture-critical applications. Higher ductility, better cryogenic toughness — used for safety-critical brackets and fittings.
Inconel 625 / 718
Nickel superalloys for hot-section components — engine mounts, turbine fixtures, exhaust hardware. Resists oxidation to 900°C+.
7075-T651 Aluminum
Highest-strength aluminum alloy for structural airframe components. Better strength-to-weight than 2024-T351 for most aerospace structures.
PEEK (medical/aerospace grade)
High-temp polymer for hydraulic seals, electrical insulators, cable cleats. Outgassing-controlled grades available for satellite applications.
Stainless Steel 17-4 PH / 15-5 PH
Precipitation-hardening stainless for high-strength, corrosion-resistant aerospace fittings. Aging temperatures controlled per AMS specs.
Processes & equipment
5-axis CNC milling (DMG MORI DMU 80, Mazak VARIAXIS)
Complex impellers, structural brackets, blade fixtures — single setup eliminates re-fixturing tolerance stack-up.
Wire EDM (Sodick, Mitsubishi)
Internal features < R 0.2 mm, hardened-material slots, complex profiles unreachable by milling cutters.
Swiss-type CNC turning (Citizen L20/L25/L32)
High-precision small-diameter components: connector pins, hydraulic fittings, sensor housings up to Ø 32 mm.
Surface grinding (precision flat & cylindrical)
Ra 0.1 µm finish, ±0.001 mm dimensional control on hardened components and tooling.
Passivation per ASTM A967 / AMS 2700
Citric acid passivation for stainless aerospace parts. Removes free iron, prevents corrosion.
Heat treatment + cryogenic stress relief
Solution annealing, aging, sub-zero stabilization for titanium and PH stainless. Hardness verified per AMS specs.
