Precision CNC Machining for Defense Teams

Defense companies in Union City need parts that are exact, traceable, and compliant. A weapon mount that's out of spec affects reliability in the field. We machine aluminum 7075, 4340 steel, and titanium 6Al-4V to tolerances as tight as ±0.0005 inches. We are pursuing ITAR registration and handle controlled technology with proper export controls.
