They Machine This From a 6,000-Lb Metal Block – And It Flies

Witness the incredible transformation of a massive 6,000-lb block of aluminum-lithium into a critical flight component. This is not just machining; this is the extreme engineering behind the airplane wings that carry millions of passengers every day.

In this cinematic documentary, we go inside the hidden factory where raw metal billets are carved, dissolved in acid, and coated in emerald green protection to withstand the forces of flight. From high-speed 5-axis Makino CNC mills to the precise chemical milling tanks, see how the Boeing 787 and Airbus A350 wings are born.

🔥 Key Processes in this Video:

1. Heavy Machining: Watch a 12,000 RPM spindle shred aerospace-grade aluminum.
2. Chemical Milling: The science of using sodium hydroxide at 180°F to etch metal.
3. The "Green" Coating: Applying Alodine conversion coating for 30-year corrosion resistance.
4. Final Assembly: Fitting the triple-slotted Fowler flaps that control lift.
