The Age of Rebirth: from Fitter Apprentice to Great Country Craftsman

Traveling back to the 1950s, Song Yang became a fitter apprentice at the Beijing Machinery Factory. Faced with the poor domestic industrial level and the international blockade environment, he used the existing resources and conditions to start the promotion and application of "small technological innovation" and "local construction", and realized the innovation of "small technology with big impact". The promotion of group drilling technology has increased drilling efficiency by 3-5 times; cyclone milling and simple tooling fixtures have increased the production capacity of existing milling machines and lathes several times without adding new equipment; ductile iron technology allows cheap pig iron to produce parts with performance comparable to steel. "Replacing boring with lathes", "high-speed cutting method", "slender shaft turning method", "tire die forging"... These technologies are like seeds that continued to grow in the industrial soil of the 1950s, and eventually grew into the solid foundation that supports the towering tree of the Huaguo Industrial Building. Many years later, when someone said to him: Chief Engineer Song, you are indispensable for China's industrial foundation to be so solid. Song Yang waved his hand and said: I am just standing on the shoulders of countless people.
