Capabilities

At TEC Aerospace, our in-house manufacturing capabilities are central to our ability to deliver mission-critical military parts with uncompromising precision and reliability. We strategically utilize a fleet of advanced, American-made Haas CNC machines to handle a wide range of production demands. Our Haas Milling machines, including versatile VF-Series and 5-axis machining centers, allow us to produce components with complex geometries, such as hydraulic manifolds and structural airframe parts, from advanced materials like titanium and high-strength alloys. For rotational components, our Haas ST-series CNC lathes are indispensable. Equipped with live tooling and Y-axis capabilities, these machines enable us to perform multiple operations like turning, milling, and drilling in a single setup, ensuring exceptional accuracy and concentricity for parts like MIL-SPEC fasteners, sleeves, and spacers. Complementing these are our high-speed Haas Drill & Tap centers, which leverage high-RPM spindles and rapid rigid tapping to efficiently produce the precise, numerous threaded features common in military assemblies. This integrated ecosystem of Haas machinery forms the backbone of our commitment to producing high-quality components that meet the stringent tolerances and performance standards required by the defense industry.
