CNC turret is the customary term for a modern and efficient tool holder. It is an integral part of modern digital manufacturing technology. Over the past decade, with the manufacturing industry to accelerate the pace of modernization, China's digital manufacturing technology has gained rapid development. Of the 20th century, China's annual output of metal-cutting machine tools reached 190,000 units, but only 14,000 units of CNC machine tools; then to new carbide knife as the representative of a modern and efficient turret, turret value of all has only 15 %. After entering the new century, the pace of development of China's machine tool industry greatly accelerated frame work, in 2007, China's CNC machine tool production reached 123,200 units, output NC rate reached 43.7%. The proportion of high-performance carbide knife with this match, also rose to 40.3% of all knife output. Thus, entering the new century, China's CNC machine tool and efficient knife, made a rapid, synchronous development. At present, the localization of a modern and efficient turret, has entered the bulk of the automotive industry, mold industry, aerospace, power generation equipment, general machinery and other fields. Performance of some products has been at or near the international advanced level, effectively breaking the monopoly of imported knife in some areas, to regulate competition in the market of high-turret contributed.
