Background

The development of cutters has taken a significant role in the history of human progress. Copper cutters such as brass cones and copper cones, drills, cutters and the like are already appeared in China as early as 28 to 20 centuries before the male element. In the late war state (the first three centuries of the primordial), copper tools were made by mastering carburization techniques. Drill bits and saws at that time have somewhat resembled modern spade drills and saws, however, the rapid development of cutters has been accompanied by the development of machines such as steamers in the late 18 th century. In 1783, the mill was first manufactured in french lux. In 1792, british morse notes made taps and dies. The earliest literature on twist drills was written in 1822, but the twist drills were not produced as commercial products until 1864, and when alloy tool steels were used, the cutting speed of the cutters was increased to about 8 m/min, and when high-speed steels were used, the cutting speed was increased by more than two times, and when cemented carbides were used, the surface quality and dimensional accuracy of the cut work pieces were also greatly improved.
