What is an aerospace machine shop?
An aerospace machine shop is a specialized precision manufacturing facility that produces components for aircraft, spacecraft, defense systems, and aviation applications. These shops use advanced CNC machining equipment to create parts with extremely tight tolerances, often working with aerospace-grade materials like titanium and aluminum alloys. Aerospace machine shops must meet rigorous quality standards including ISO 9001 certification, maintain complete traceability documentation, and often hold ITAR registration for defense-related work.
