Who can talk about the theoretical knowledge test of intermediate CNC lathe workers in Shandong Province?

I also study numerical control, and I just passed the intermediate certificate, which is quite easy. Personally, I think it is very important to go out to work in the future. It can also show that you are actually an intermediate worker. And since I chose to study CNC, of course, I have to take the lathe work certificate.

The so-called ordinary lathe: refers to the universal lathe, the operation is relatively simple (numerical control). It came out earlier, and now it is widely used in the secondary industry (industry), which is very practical. . CNC lathe: Its essence is the optimization of ordinary lathe. On the basis of ordinary lathe, a numerical control programming system is added, which can make the lathe have complex process graphics. After the computer is implanted with the program, the CNC lathe can process complex parts according to the program, and the same program can be reused to obtain high-precision and high-efficiency production level.

Numerical control lathe is an advanced equipment controlled by computer software on the basis of the original ordinary lathe, and its accuracy is higher than that of ordinary lathe. Because many imported equipment are ball screws, the guide rail is fully enclosed, and there are many commonly used systems such as falak Siemens; Mitsubishi and others. The main advantages are that it is more convenient to process arcs and angles than ordinary equipment, and the tools are mostly machined, which greatly improves the finish and has little spare time. In a word, if you are engaged in machinery industry, you will choose CNC lathe for processing, which will greatly improve the quality and output.

In recent years, with the development of computer technology, digital control technology has been widely used in various fields of industrial control, especially in the field of machinery manufacturing. Ordinary machinery is gradually being replaced by numerical control machinery with high efficiency, high precision and high automation. At present, the numerical control rate of mechanical equipment abroad has reached more than 85%, while the numerical control rate of mechanical equipment in China is less than 20%. With the application of new technology in China machinery industry, China's position as a world manufacturing center has been formed, and the use, maintenance and maintenance personnel of CNC machine tools are very scarce in industrial cities all over the country. In addition, CNC machining personnel have a wide range of employment. Can be engaged in computer drawing, numerical control programming design, machining center operation, mold design and manufacturing, EDM, wire cutting and other modern manufacturing industries such as molds, watches, hardware industry and small and medium-sized manufacturing industries. Therefore, the existing numerical control technical talents can not meet the demand of manufacturing industry, and the talent market is not large. It is difficult for enterprises to find suitable talents in the talent market, which leads to mold design, CAD/CAM engineer, NC programming and wire cutting. In all kinds of job fairs, CNC professionals are one of the few positions that enterprises are keen to mark as "urgent employment" and "high salary recruitment", which makes it difficult for CNC technicians with a monthly salary of 6,000 yuan and an annual salary of 6,543.8+0.6 million yuan to recruit. According to the newspaper, senior technicians in China are facing a grim situation of "green and yellow". Old technicians are old, middle-aged technicians are few, and young technicians are not mature yet. In the manufacturing industry, talents who can skillfully operate modern machine tools are scarce. According to statistics, at present, among skilled workers in China, senior technicians account for 3.5%, intermediate workers account for 35% and junior workers account for 60%. Among the skilled workers in developed countries, senior workers account for 35%, intermediate workers account for 50% and junior workers account for 15%. It can be seen that in the next 5- 10 years, the gap of senior technicians in China is still large. With the adjustment of industrial layout and product structure, the employment structure will also change. The demand of enterprises for higher-level first-line applied talents will increase significantly. With the help of foreign development experience, when entering the period of industrial layout and product structure adjustment, it is urgent to match the industrial structure and cultivate a considerable number of professionals with high cultural level. For CNC machining specialty, not only practitioners are required to have excellent practical ability, but also a solid knowledge of machining theory. Therefore, CNC machining talents with both academic qualifications and strong operational ability have become the most urgently needed talents in society and enterprises.
