The application of numerical control technology has not only brought revolutionary changes to the traditional manufacturing industry, making the manufacturing industry a symbol of industrialization, but also with the continuous development of numerical control technology and the expansion of application fields, it plays an increasingly important role in the development of some important industries (IT, automobile, light industry, medical treatment, etc.) of the national economy and the people's livelihood, because the digitalization of the equipment required by these industries has become a major trend of modern development. At present, CNC lathes present the following development trends.

The common lathe has a wide range of machining objects, a wide range of spindle speed and feed adjustment, and can process the internal and external surfaces, end faces, and internal and external threads of workpieces. This kind of lathe is mainly manually operated by workers, with low production efficiency, and is suitable for single piece, small batch production and repair workshops.
