Development history of CNC tools


    The development of cutting tools plays an important role in the history of human progress. As early as the 28th century BC to the 20th century BC, brass cones and pure copper cones, drills, knives and other copper tools have appeared in China. In the late Warring States period (the 3rd century BC), due to mastering the carburizing technology, steel knives were made. At that time, drills and saws had some similarities with modern flat drills and saws. However, the rapid development of cutting tools came in the late 18th century with the development of steam engines and other machines. In 1783, Rene in France first produced a milling cutter. In 1792, Mozley, England, produced taps and dies. The earliest literature record about the invention of Fried Dough Twists drill was in 1822, but it was not produced as a commodity until 1864.
