Development of machining technology

Before the industrial revolution, machinery and most of them are wood, made from wood by hand. Metal (primarily copper and iron) used to manufacture instruments only, locks, clock, pumps, and small parts of wood machinery. Metal processing mainly by machine maker Seiko, to achieve the required accuracy. Extension of steam turbine power plant, and appears with mining, metallurgy, ships, locomotives and other large machinery development, need forming and machining of metal parts, more and more, more and more, required accuracy is increasing. Application of metals from copper and iron to steel. Machining including casting, metal forming, sheet metal, welding, heat treatment technology and equipment, and cutting processing technology and machine tools, cutting tools, measuring tools, develop rapidly, ensuring the supply of machinery and equipment needed for the production of industrial development.
