CNC machine tools are growing at a high speed but there is a shortage of CNC talents
February 28, 2023
China's machine tool industry is in a high-speed growth momentum. From January to May this year, the production and sales growth of the CNC machine tool industry reached about 40%. In June, the output growth rate of CNC machine tools slowed down compared with the beginning of the year, but remained high. The level of growth. After the country issued a series of related support policies, investors' confidence in China's manufacturing industry increased, driving demand in the domestic market to increase. A number of high-growth industries based on heavy industry, such as coal, automobiles, steel, real estate, building materials, machinery, electronics, and chemicals, have a strong momentum of development, which constitutes a huge demand for the machine tool market, especially CNC machine tools. CNC machine tools have become the mainstream of machine tool consumption, and CNC machine tools companies have not stopped and have been rushing forward.
Lack of CNC talent
With the increasing demand for CNC machine tools, CNC technology has been widely used in various fields, and the demand for talents has gradually increased. However, there is a shortage of numerical control talents in China, and there is an urgent need for a large number of technical talents from research and development to use and maintenance. At present, the demand for CNC talents is mainly concentrated in the following enterprises and regions:
1. State-owned large and medium-sized enterprises, especially the current military enterprises with good economic returns and national major equipment manufacturing enterprises. The military manufacturing industry is the main application object of China's numerical control technology. Hangzhou Power Generation Equipment Factory can't recruit CNC operators with 6000 yuan monthly salary. .
2. With the rapid development of the private economy, China's coastal economically developed regions (such as Guangdong, Zhejiang, Jiangsu, Shandong), CNC talents are in short supply, mainly concentrated in mold manufacturing enterprises and auto parts manufacturing enterprises.
According to relevant data, the numerical control rate of foreign mechanical equipment has reached more than 85%, and the numerical control rate of mechanical equipment in China is less than 30%. The application of new technology and new technology in the machinery manufacturing industry, molds of modern manufacturing, The watch industry, hardware industry, small and medium-sized manufacturing, computer graphics, CNC programming design, mold design and manufacturing, etc., have extensively touched and used CNC technology, and the demand for talent is indeed very large.
CNC operator culture is uneven
Most of the numerical control operators come from ordinary machining, and the cultural quality is uneven. In the application of numerical control equipment, the idea of ordinary equipment processing is applied. The characteristics of high-speed cutting of CNC machine tools, the selection of CNC tools and the selection of cutting parameters are not scientific. The advantages and disadvantages of the processing program and the level of processing efficiency depend entirely on the quality of the operators, and the processing efficiency of the numerical control equipment cannot be maximized.
Resolve measures to popularize low-end and focus on high-end
“The numerical control operator has the same technical content as the sweeping.” This is the view of Zhang Yu, the head of a machinery manufacturing company in Chengdu. He believes that some of the NC majors who are graduating now are not familiar with the basic operations, and some of the products that have been made are often defective. Some of them have low-handedness and will not be able to change jobs for a long time. “This actually reflects the problem of talent training in schools.” Mr. Wen, the vice president of Chengdu Changzheng Mechanical and Electrical School, said that the current status of the training of CNC majors in most schools is that they focus on basic knowledge training, light and high professional development; Classroom learning, machine tool training, light enterprise cooperation on-site teaching; heavy knowledge transfer light professional ethics training. With the large increase in the number of NC majors and the slowdown in the employment of low-end jobs in the industry, these hidden concerns will be further exposed.
“From the perspective of the foreign CNC professional, there is no future for a simple CNC operator.” Mr. Chen, a CNC professional teacher at the Vocational and Technical College of Southwest Jiaotong University, said that just like the computer major 10 years ago, at that time, school training Computer talent is in short supply. Nowadays, computers have basically become a general profession, and employment is not easy. From the development direction of the global CNC industry, the use of ordinary CNC machine tools is more and more extensive, and the degree of intelligence of CNC machine tools is getting higher and higher, and gradually has the functions of self-diagnosis, adaptive control, logic analysis and judgment, except for a small amount. Outside the high-precision manufacturing industry, the degree of intelligence of the system is increasing, and the requirements for operators are decreasing.
In this regard, some forward-thinking schools have proposed countermeasures, that is, popularizing the low-end and focusing on high-end. A school in Chengdu proposed that in the form of elective courses, more professional students can learn CNC, so that after entering the enterprise, the NC knowledge is basically sufficient. For a small number of professional learners, deeper theoretical and operational courses are opened and strengthened. Professional ethics education.
