美国的钢铁巨人：世界最强的金属工匠

Machine Thinking tells the story of the Cold War Heavy Press Program, the giant forging presses that make parts for aircraft, missiles and turbines.

Why HN likes it: HN commenters recommend it as an excellent introduction to massive forging presses, especially in threads about gigacasting and large manufacturing machines.

“I first learned about these presses several years ago from the YouTube channel Machine Thinking which is excellent and unfortunately infrequent.”
