CNC tool development progress
CNC tool development occupies an important position in the history of human progress. The brass cone and copper, diamond, copper CNC tools had already appeared in China as early as BC 28 ~ the 20th century. People at that time mastered carburizing technology, so copper CNC cutting tool was made. The drill and saw has some similarities with the modern flat drill and saw. However, the fast development of the CNC tool was in the late 18th century, along with the development of the steam engine and other machines. In 1783, Rene in France developed the first cutter system. In 1792, the British Maudslay made tap and die system. The earliest document for twist drill invention was in 1822, but it was not produced as commodity until 1864.
CNC tool cutting speed is constantly increased
The CNC tool at that time was manufactured by overall carbon tool steel, allowable cutting speed was about 5 m / min. In 1868, the British Muchet made tungsten alloy tool steel. In 1898, the American Taylor and White invented high-speed steel. In 1923, the Germany Schroter invented Carbide. When using alloy tool steel, CNC tool cutting speed has been increased to about 8 m / min, which had been raised more than twice at the use of high-speed steel; until using hard alloy, it improved more than twice than high-speed steel, the cutting workpiece surface quality and dimensional accuracy are also greatly improved.
CNC tool structure has been greatly enriched
Because the price of high-speed steel and carbide is more expensive, CNC tool has welding and mechanical folder solid structure. Machine tools and CNC tool development are complementary and mutually reinforcing. The NC tool is the most active factor in the process system composed by cutting machine tools, CNC tool and workpiece. Whether the CNC tool holders performance is good or bad depends on the CNC tool material and CNC tool structure. The cutting productivity, the CNC tool life, processing cost, machining precision and the pros and cons of surface quality largely depends on reasonable choice of CNC tool materials, CNC tool structure and cutting parameters. As the most basic cutting, CNC tool materials have rapidly developed in recent decades, the CNC tool structure has also been greatly enriched.
