Manufacturing titanium components for aerospace propulsion and structural airframes requires absolute adherence to the AS9100D quality management standard and NADCAP special process accreditations. When CNC-machining critical elements like aircraft engine bulkheads or dynamic rotor heads from Grade 5 titanium, the process must mitigate micro-structural damage induced by high thermal stresses. BOZE strictly controls the surface integrity by enforcing specialized milling parameters that eliminate the formation of the brittle alpha-case layer, ensuring zero micro-cracks.
All high-stress fasteners and structural brackets undergo non-destructive testing (NDT), including liquid penetrant inspection per ASTM E1417 and digital radiography to detect subsurface discontinuities. Microstructural verification guarantees that the grain size conforms perfectly to ASTM E112 standards, securing maximum fatigue life under extreme cyclic aerodynamic loading. Full EN 10204 3.1 material traceability and AS9102 First Article Inspection reports accompany every aerospace lot.
Medical & Biomedical Devices — ISO 13485 & FDA Title 21 CFR Part 820
For long-term human implants such as orthopedic bone screws, trauma plates, and dental implant abutments, production must comply with ISO 13485 and FDA Title 21 CFR Part 820 quality system regulations. Utilizing Grade 23 ELI (Extra Low Interstitials) titanium, BOZE deploys specialized multi-axis CNC Swiss Lathes operating inside controlled cleanroom zones. To ensure absolute biocompatibility, our production protocol enforces a strict zero-contamination workflow, completely banning all lubricants containing heavy metals, chlorine, or sulfur.
Post-machining surface treatments strictly follow ASTM F86 surface preparation guidelines. Components undergo an automated multi-stage deionized water ultrasonic cleaning validation lifecycle to eliminate organic hydrocarbon micro-residues, guaranteeing compliance with ISO 10993 biocompatibility, non-cytotoxicity, and bio-burden thresholds before sterile packaging.
Titanium components integrated into semiconductor gas delivery networks, matrix chambers, and ultra-high vacuum (UHV) systems must align precisely with the SEMI F20 specification. The critical metric here is eliminating gas desorption outgassing pathways and preventing chemical reactions with corrosive precursor gases. BOZE machines these specialized vacuum components under strict temperature-controlled environments to hold tolerances within 0.01 mm.
Following machining, components undergo specialized electropolishing (EP) and chemical passivation protocols per ASTM A967, yielding an ultra-smooth internal surface finish with a roughness value of Ra ≤ 0.2 µm. This crystalline surface refinement effectively eliminates microscopic pits and structural crevices, preventing volatile fluid stagnation nodes and ensuring high-purity vacuum integrity under 10⁻⁹ Torr operating conditions.
