CNC lathe is a kind of numerical control machine tool which is widely used at present. This product is mainly used for cutting the inner and outer cylindrical surface of shaft or disc parts, the inner and outer conical surface of any type of NC machine tool cone Angle, the inner and outer curved surface of complex rotation, as well as the cylindrical and cone threads, etc., and can be used for grooving, drilling, expanding, reaming, boring, etc.

CNC lathe, also known as CNC lathe, namely computer digital control lathe, is currently the most widely used in China, the most widely used CNC lathe, accounting for about 25% of the whole CNC machine tools. CNC machine tool is a collection of mechanical, electrical, hydraulic, pneumatic, microelectronics, information technology in one of the mechatronics products. In the machinery manufacturing equipment, the working machine has the advantages of high precision, high efficiency, high degree of automation, good flexibility and so on. The technical level of CNC machine tool and its share in the metal cutting machine tool recovery CNC machine tool is one of the important signs to measure the level of development of a country's national economy and the overall level of industrial manufacturing industry. CNC lathe is one of the main varieties of CNC machine tools, its importance is self-evident, in recent decades, CNC lathe in the world has attracted wide attention, and has been a rapid development.

Since its emergence in the 1950s, CNC lathe as a single production, small batch production tools, used for the processing of complex shape parts, not only improve labor productivity and processing quality, but also shorten the production preparation period, reduce the numerical control machine tool model for workers skills requirements. Thus, it becomes an important development direction of technological innovation and technological revolution in small batch production. This new technology is also being developed in countries around the world.
