Precision CNC Machining Services

Southern Precision Machining is a woman-owned company providing precision CNC machining services specifically designed to meet the needs of the aerospace industry. We are ISO 9001:2015 and AS 9100D certified, and registered with ITAR. Machining capabilities include profiling, pocketing, drilling, boring, turning, and threading. Our CNC machining centers are 5-axis capable for complex milling of intricate parts while holding a true position tolerance of ±.001”. Length and diameter tolerances can be held to ±.001” and verified with precision CMM equipment. We machine a number of materials including Titanium, steel, stainless steel, and aluminum alloys up to 170” x 50” x 39” for milled parts and up to 22” in diameter for turned parts. To learn more about the equipment available at SPM, visit our equipment page SPM Equipment List.

Leading OEMs including Boeing, Airbus, and Lockheed Martin and Gulfstream have trusted SPM to provide them with quality Airframe parts and assemblies. SPM maintains partnerships with a number of qualified vendors to provide value added heat treating and finishing services, simplifying customers’ supply chains. We are dedicated to quality parts, on time delivery and provide complete material traceability reports.
