What is CNC? Will it be easy to find a job in the future?

Employment prospects of the CNC technology major

The CNC technology major is a knowledge-intensive technology that integrates mechanical, electrical, hydraulic, optical, computer, and automatic control technologies. It is a manufacturing It is the basis for the industry to realize modernization, flexibility and integrated production, and it is also an indispensable material means to improve product quality and increase productivity.

The economic benefits gained by the adoption of CNC technology in industrially developed countries such as Japan, the United States, and Germany are roughly as follows: 50% reduction in operating personnel, 60% reduction in costs, 60%-80% machine tool utilization, and 60% reduction in the number of machine tools. A 50% reduction and a 40% reduction in production area. Due to the widespread application of CNC technology in the world's manufacturing industry, ordinary machinery is gradually replaced by high-efficiency, high-precision CNC equipment. The widespread application of CNC technology in the machinery manufacturing industry has become a powerful driving force for the development of the national economy.

After joining the WTO, with the rapid economic development, China is gradually becoming the "world manufacturing center", and the CNC rate has become one of the important indicators to measure the manufacturing technology level and economic strength of a country or enterprise. (CNC rate: the proportion of CNC equipment in equipment ownership). At present, the CNC rate of machine tools in my country is only 1.9%, while it is as high as 30% in Japan and more than 40% in the United States. CNC machine tools have been widely used in developed countries, but the application and promotion of CNC technology in my country is far behind that of developed countries. Our country will add 400,000 to 500,000 CNC machine tools within a few years, correspondingly requiring 600,000 to 800,000 CNC professional and technical personnel.

Practice in the CNC industry can be roughly divided into three levels:

1. Blue-collar level: CNC operating technicians, proficient in mechanical processing and CNC processing technology knowledge, and proficient in the operation of CNC machine tools Operation and manual programming, understanding of automatic programming and simple maintenance and repair of CNC machine tools. Such personnel are in high demand in the market and are suitable as CNC machine tool operators in workshops. However, due to their relatively simple knowledge, their salary will not be much high.

2. Gray-collar layer: First, CNC programmers: master the knowledge of CNC machining technology and the operation of CNC machine tools, be familiar with the design and manufacturing expertise of complex molds, and be proficient in three-dimensional CAD/CAM software, such as UG, PRO/E, etc.; proficient in CNC automatic programming and manual programming technology. Such personnel are in high demand, especially in the mold industry, and are very popular and receive high remuneration. Second, CNC machine tool maintenance and repair personnel: master the mechanical structure and electromechanical joint debugging of CNC machine tools, master the operation and programming of CNC machine tools, and be familiar with the characteristics, software and hardware structures, PLC and parameter settings of various CNC systems. Proficient in mechanical and electrical debugging and maintenance of CNC machine tools. The demand for such personnel is relatively small, but cultivating such personnel is not easy and requires the accumulation of a lot of practical experience. It is currently in short supply and their remuneration is also relatively high.

3. Golden collar level: CNC generalists who possess and are proficient in the comprehensive knowledge required by CNC operating technicians, CNC programmers and CNC maintenance and repair personnel, and have accumulated a lot of practical experience in actual work. The knowledge is very broad. Proficient in the mechanical structure design of CNC machine tools and the electrical design of CNC systems, and master the electromechanical joint debugging of CNC machine tools. Able to complete the selection of CNC systems, design, installation, debugging and maintenance of CNC machine tool electrical systems by themselves. Able to independently complete CNC transformation of machine tools. They are sought-after talents in enterprises (especially private enterprises) and their remuneration is very high.

With the application of new technologies in my country's mechanism industry, my country's position as the world's manufacturing processing center has been formed. Personnel for the use, repair and maintenance of CNC machine tools are in very short supply in various industrial cities across the country. In addition, CNC processing personnel The scope of employment is very wide, and it can be engaged in modern manufacturing molds, watch industry, hardware industry, small and medium-sized manufacturing industry, computer graphics, CNC programming design, machining center operation, mold design and manufacturing, EDM and wire cutting for corresponding companies and enterprises. , so the existing CNC technical talents cannot meet the needs of the manufacturing industry, and the talent pool in the talent market is not large. It is more difficult for companies to find suitable talents in the talent market, which leads to mold design, CAD /CAM engineers, CNC programming, CNC machining, etc. have become one of the most frequently recruited positions in various talent markets in my country.

my country's senior technicians are facing a serious situation of "a shortage of jobs". The original technicians are old, there are only a few middle-aged technicians, and the young technicians are not yet mature. In the manufacturing industry, talents who can skillfully operate modern machine tools have become scarce. According to statistics, among my country's skilled workers, 3.5 are senior technicians, 35 are intermediate workers, and 60 are junior workers. Among the skilled workers in developed countries, 35% are senior workers, 50% are intermediate workers, and 15% are junior workers. With the adjustment of industrial layout and product structure, the employment structure will also change. Enterprises' demand for higher-level front-line application talents will increase significantly.

With the help of foreign development experience, when entering the period of industrial layout and product structure adjustment, it has become an urgent requirement to highly match the industrial structure and cultivate a considerable number of professional talents with high educational levels. For the CNC machining major, practitioners are not only required to have excellent practical abilities, but also to master systematic and solid theoretical knowledge of machine machining. Therefore, CNC processing talents with both academic qualifications and strong operational abilities have become the talents that are in short supply in society and most urgently needed by enterprises.

But the most basic thing is to start with an ordinary lathe: a solid foundation and wide application. Then you should also gradually understand and master CNC lathes. There are several general aspects that students who learn to drive should know. 1. Have an accurate understanding of the lathe you are using. You must be very familiar with its structure, functions and functions of each component. It is necessary to understand the materials, characteristics, and uses of various cutting tools; it is also necessary to master the geometry, performance, and processing methods of the cutting tools. Be able to use measuring tools, calipers, micrometers, calipers, etc. Of course, you must also be able to understand the drawings. 2. Lathe work is a very technical job, which mainly depends on practice. Turning processing is nothing more than inner holes, outer circles, end faces, threads, crankshafts, etc. These are technologies that must be mastered through hard work. You have to study hard in mind and hands. 3. Learner drivers must pay attention to safety first. Neither personal safety nor equipment safety can be compromised. I believe you will become a technical expert.
