CNC Milling
Precision 3-, 4-, and 5-axis CNC milling for complex UAV structural and mechanical components, delivering tight tolerances, repeatable accuracy, and consistent surface finishes for flight-critical parts.
UAVs and drones demand components machined to exacting tolerances—where even the smallest deviation can mean mission failure. Criterion Precision Machining delivers Swiss turning, CNC milling, and precision inspection for drone and UAV parts that perform flawlessly in the field. From lightweight airframe elements to intricate actuation components, we machine to ± .0002" with zero-compromise quality standards.

From complex multi-axis milling to micro-tolerance Swiss turning, we deliver every drone component with mission-critical precision.
