What aerospace standards and certifications apply to Neway’s titanium machining?
Neway's titanium machining for the aerospace sector is governed by a rigorous multi-layered compliance framework, ensuring that every component meets the extreme demands for safety, reliability, and traceability. This adherence is not merely about having certificates but involves a deeply integrated quality management system that controls every aspect of the manufacturing process.
The Foundation: AS9100 Quality Management System
At the core of our aerospace manufacturing is the AS9100 Rev D certification. This is the international Quality Management System (QMS) standard specifically for the aerospace industry. It builds upon ISO 9001 with additional requirements for critical areas such as risk management, project management, and configuration control. For our Titanium CNC Machining Service, this means every process—from initial quote and raw material procurement to final inspection and shipping—is documented, controlled, and continuously improved. It ensures robust traceability, where each component can be tracked back to its original material heat lot, and all processing data is retained.
Controlling the Material: AMS and ASTM Standards
The performance of aerospace titanium is dictated by strict material standards. We routinely machine titanium alloys to specifications such as:
AMS 4928: Covers Ti-6Al-4V annealed bar, wire, and ring forms.
AMS 4934: Pertains to forged Ti-6Al-4V hand forgings and rings.
AMS 4967: Specifies the requirements for Ti-6Al-4V ELI (Extra Low Interstitial) wire, used in critical applications like medical implants within aerospace medical suites.
ASTM B348: A key standard for titanium and titanium alloy bars and billets.
Compliance means verifying material certifications against these standards, ensuring chemistry and mechanical properties like tensile strength, yield strength, and fracture toughness are fully met before machining begins.
Validating the Processes: NADCAP Accreditation
While AS9100 covers the overall QMS, Nadcap (National Aerospace and Defense Contractors Accreditation Program) provides independent, industry-managed accreditation for special processes. For titanium machining, the most critical Nadcap accreditations involve:
Heat Treating: Titanium is extremely sensitive to contamination and thermal cycle. Nadcap-accredited Heat Treatment for CNC Machining ensures processes like stress relieving and annealing are performed in controlled furnaces with precise atmosphere control to prevent embrittlement and ensure mechanical properties.
Non-Destructive Testing (NDT): Critical for detecting internal and surface flaws. We utilize Nadcap-accredited NDT methods such as Fluorescent Penetrant Inspection (FPI) and Ultrasonic Testing to validate the integrity of machined components, ensuring they are free from detrimental discontinuities.
Ensuring Part Integrity: Geometric Dimensioning and Tolerancing (GD&T)
Aerospace designs rely heavily on GD&T to define functional requirements. Our Precision Machining Service and Multi-Axis Machining Service are equipped with advanced CMMs (Coordinate Measuring Machines) and metrology software to verify complex GD&T (Geometric Dimensioning and Tolerancing) callouts, including true position, surface profile, and runout, ensuring parts conform perfectly to the engineering design intent.
Meeting Original Equipment Manufacturer (OEM) Requirements
Beyond generic standards, we comply with the specific requirements of major aerospace OEMs. This often involves being listed on their approved supplier lists and adhering to their proprietary specifications for materials, processes, and documentation. This direct compliance is essential for components destined for use in Aerospace and Aviation systems, from airframes to propulsion.
A Culture of Compliance and Traceability
Ultimately, our certification is embedded in our culture. It means every operator and engineer is trained in the requirements of aerospace manufacturing. It ensures that for every titanium component we produce, there is a complete and auditable data package—including material certs, process travelers, heat treat records, and final inspection reports—providing our customers with absolute confidence in the quality and airworthiness of every part.
