As the times are changing, there are many processing technologies around us, each is different, in the industry, making a different contribution, precision machining is one of them, then the development of machining technology is not very good?
Before the industrial revolution, machinery is mostly made of wood structure by hand by carpenters, metal (mainly steel and iron) is only used to manufacture instruments, clocks, locks, pumps and small parts on wooden machinery. Metal processing mainly relied on the machinist's fine work to achieve the required precision. With the widespread use of steam engines and the subsequent emergence of mining, metallurgy, ships and locomotives and other large machinery development, the need for forming and cutting metal parts more and more, the metal materials used from copper, iron to the development of steel-based.
Mechanical processing (including casting, forging, welding, heat treatment and other technologies and their equipment, as well as cutting and machining technology and machine tools, tools, gauges, etc.) developed rapidly, thus ensuring the development of the supply of various mechanical equipment needed for production. At the same time, with the increase in production volume and the development of precision processing technology, but also to promote the formation of a large number of production methods (parts interchangeable production, professional division of labor and collaboration, flow processing line and flow assembly line, etc.).
