How long CNC apprentices usually study varies from person to person, depending on the individual's acceptance ability. People with a good foundation can start school in six months to one year, while those with poor acceptance and no foundation generally have to study for two to three years.

Learning CNC lathe requires some basic knowledge, such as mathematics, physics, mechanical drawing and so on. It usually takes about 2-3 years to master it skillfully. Apprentices need to master the basic knowledge of CNC lathe structure, working principle, programming method, tool selection, machining technology and so on, and also need to master the operation skills of CNC machine tools. CNC lathe apprentices need to study for about 2-3 years, but the actual study time will vary from person to person, depending on learning foundation, learning attitude, practical experience and other factors. During the study period, apprentices need to study hard, practice diligently and constantly improve their technical level in order to become a qualified CNC lathe technician. With the application of new technology in China's machinery industry, China's position as the machining center of the world manufacturing industry has been formed, and the use, maintenance and maintenance personnel of CNC machine tools are in short supply in industrial cities all over the country. In addition, CNC machining personnel have a wide range of jobs, and can engage in computer drawing, CNC programming design, machining center operation, mold design and manufacturing, EDM, wire cutting and other work in modern manufacturing industries such as molds, watches, hardware industry and small and medium-sized manufacturing industries. Therefore, at present, the existing numerical control technical talents can't meet the demand of manufacturing industry, and the reserve of such talents in the talent market is not large, and it is more difficult for enterprises to find suitable talents in the talent market, so that mold design, CAD/CAM engineer, numerical control programming and numerical control machining have become one of the positions with the highest recruitment frequency in various talent markets in China. Therefore, CNC machining talents with both academic qualifications and strong operational ability have become the most urgently needed talents in society and enterprises.
