We routinely achieve tolerances as tight as ±0.002 inches (±0.05 mm) for metal skins and ±0.005 inches for composite panels, ensuring precise contour accuracy, proper rivet hole alignment, and optimal fit with underlying structures.

Aircraft skin production utilizes advanced machining and fabrication technologies:
3-axis and 5-axis CNC routing for precise panel trimming and edge profiling
CNC drilling for rivet holes and fastener patterns
Contour milling for smooth curved surfaces
Composite machining for carbon fiber and fiberglass panels
Precision deburring and edge finishing for assembly-ready surfaces

Each material offers distinct advantages for skin panel applications:
