Before the industrial revolution, the machinery was mostly made of wood structure, metal (mainly Gang Hetie) used to manufacture equipment, Zhong Biao, lock, pump and wood structure of small parts. Metal processing mainly depends on the maker of Seiko secret agents in order to achieve required accuracy. With the development of the wide use of the steam engine and the resulting mines, metallurgy, ships and locomotives, large machinery, forming processing and cutting of metal parts becomes more and more, the metal materials by copper, iron to steel.

Rapid development of mechanical processing (including casting, forging, welding, heat treatment, such as technology and its equipment and machining technology and machine tools, cutting tools, measuring tools, etc.), so as to ensure the development of production of all kinds of machinery and equipment supply. At the same time, with the development of the bulk of the production increasing and precision processing technology, but also to promote the formation of mass production methods (interchangeable parts production, specialized division of labor and cooperation, water processing line and assembly line, etc.).
