Development of mechanical processing technology

Machining (including casting, forging, welding, heat treatment technology and equipment and cutting technology and machine tools, cutting tools, measuring tools, etc.) developed rapidly, thus ensuring the supply of various machinery and equipment needed for the development of production. Meanwhile, with the development of production volume increases and precision processing technology, also contributed to the mass production method (production of parts interchangeability, the professional division of labor and cooperation, water processing line and assembly line, etc.) is formed.

Before the Industrial Revolution, the mechanical structure consists of mostly wooden handmade carpentry, metal (mainly iron and steel) only in small parts manufacturing instruments, watches and clocks, locks, pumps and mechanical wood structure on. Metalworking mainly by machine maker Seiko secret agents in order to achieve the required accuracy. With the widespread use of the steam engine and the subsequent emergence of mining, metallurgy, ships, locomotives and other large machinery development requires forming and machining of metal parts more and more, the development of a metallic material made of copper, iron to steel as the Lord.
