Precision Manufacturing for the Demanding CNC Machining Aerospace Parts Industry

Aerospace components face some of the harshest operating conditions on earth, requiring the utmost in quality, reliability, and traceability from manufacturing partners.

Specialty CNC Machining Aerospace Parts Alloys

Unique high-strength alloys like titanium and aluminum lithium, as well as super alloys like Inconel and Haynes, present machining challenges due to work hardening. Special tooling and processes are essential for precision outcomes.

Tight Tolerances and Surface Finishes

Aerospace parts specify tolerances within +/- 0.001" and surface finishes down to 16 Ra. Submicron resolution measurement and strict process control are mandatory to meet such stringent specifications.

Extensive Certification

AS/EN/JISQ 9100 and NADCAP accreditation certify that aerospace fabricators demonstrate quality management systems with validated processes and qualified personnel for standardized part traceability and configuration control.

Special Processes Capabilities

Capabilities for heat treating, plating, non-destructive testing, and specialty machining methods like EDM and 5-axis are often requisites. Multifunctional turn-mill centers consolidate elaborate part features into a single setup.

Robust Quality Management

First Article Inspection, process FMEAs, SPC, and metrology including CMM and optical scanning ensure consistent conformance to blueprints, and facilitate customer audits.

Supply Chain Risk Management

Assemblers vet supplier quality systems and financial stability to guarantee the continuity of critical aerospace hardware production long after the original design cycles.

Engineering Collaboration

CNC machining houses partner closely with airframers and tier-one systems companies throughout new program development and lifespan support.

Pristine Production Environments

Class 7-10 cleanrooms employing stringent ESD, foreign object exclusion and contamination controls are the norm in this industry.
