High-speed growth of CNC machine tools, but the lack of numerical control personnel

China's machine tool industry is in a high-speed growth trend. From January to May this year, the growth rate of production and sales of the CNC machine tool industry reached about 40%. In June, the growth rate of CNC machine tools, although slowed down compared to the beginning of the year, remained high. The level of growth. After the country introduced a series of related supporting policies, investors’ confidence in China’s manufacturing industry has increased and the demand in the domestic market has increased. High-growth industries based on heavy industry, such as coal, automobiles, steel, real estate, building materials, machinery, electronics, and chemical industries, 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. NC machine tool companies have not stopped and have been charging forward.

The lack of numerical control personnel

With the continuous increase in the demand for CNC machine tools, CNC technology has been widely used in various fields, and the demand for talents has also gradually increased. In China, there is a shortage of numerical control personnel, and a large number of technical personnel from research and development to use and maintenance are urgently needed. At present, the demand for CNC talent is mainly concentrated in the following companies and regions:

1. Large and medium-sized state-owned enterprises, especially those that are currently economically viable, and those that are major national equipment manufacturers. The military manufacturing industry is the main application subject of China's numerical control technology. The Hangzhou Power Plant has used 6,000 yuan monthly salary to attract less CNC operators. .

2. With the rapid development of the private economy, China's coastal economically developed regions (such as Guangdong, Zhejiang, Jiangsu, and Shandong) and CNC talents are in short supply, mainly concentrated on mold manufacturing companies and auto parts manufacturing companies.

According to relevant data, at present, the numerical control rate of foreign machinery and equipment has reached More than 85%, while the numerical control rate of China's machinery and equipment is less than 30%, the application of new technologies, new processes in the machinery manufacturing industry, molds for modern manufacturing, The clock and watch industry, hardware industry, small and medium-sized manufacturing industry, computer graphics, numerical control programming design, mold design and manufacturing, etc., have all touched and used CNC technology extensively, and the demand for talents is indeed great.

CNC operator culture is uneven

Most of CNC operators come from ordinary machining, and their cultural quality is uneven. In the application of numerical control equipment, the idea of ​​general equipment processing is applied. The characteristics of high-speed cutting of CNC machine tools, choice of CNC tools, and lack of scientific choice of cutting parameters The quality of the processing program and the level of processing efficiency depend entirely on the quality of the operating personnel, and it is impossible to maximize the processing efficiency of CNC equipment.

Solutions to popularize low-end and high-end

"As with CNCs, there is no technical content." This is the view of Zhang Yu, a person in charge of a machinery manufacturing company in Chengdu. He believes that now graduated NC students, some of them are not familiar with the basic operations, some products made of defective products, some experts are low, will not be long before they will quit. "This actually reflects the problem of talent cultivation in schools." Mr. Wen, vice president of the Chengdu Changzheng CNC Electrical and Mechanical School, said that the current status of NC major training in most schools is focusing on basic knowledge training, light and high precision professional development; Classroom learning, machine tool training, light business cooperation on-site teaching; emphasis on knowledge imparted light professional ethics training. With the large number of NC students, the employment fever in the low-end jobs has gradually cooled, and these hidden concerns will be further exposed.

“From the perspective of the foreign CNC professional, there is no future for purely CNC operators.” said Mr. Chen, a CNC professional teacher at the Vocational and Technical College of Southwest Jiaotong University. Just like the computer major 10 years ago, at that time, the school was trained. The supply of computer talent is in short supply. Now, computers have basically become a general professional and employment is not easy. From the perspective of the development direction of the global numerical control industry, the use of ordinary numerical control machine tools is becoming more and more widely used. In addition, the degree of intelligence of numerical control machine tools is getting higher and higher, and it is gradually equipped with functions such as self-diagnosis, adaptive control, and logic analysis and judgment. Outside the high-precision manufacturing industry, the increase in the degree of intelligence in the system has reduced the demand for operators.

In this regard, some forward-thinking schools have proposed countermeasures, that is, popularizing the low end and refocusing on the high end. A school in Chengdu proposed that in the form of elective courses, more professional students learn numerical control, so that basic knowledge of CNC after entering the enterprise is sufficient. For a small number of professional learners, deeper theoretical courses and operation courses are established and strengthened. Professional ethics education.
