1. Blue collar layer: that is, CNC machining operation technicians, proficient in machining CNC machining process knowledge, proficient in CNC machine tool operation manual programming, understanding of automatic programming simple maintenance repair of CNC machine tools. Such personnel have a large market demand are suitable for the workshop's CNC machine tool operators. However, due to their single knowledge, their wages will be high.

2. Gray Collar layer: first, NC machining programmer: master NC machining process knowledge NC machine tool operation, be familiar with the design manufacturing of complex mold, be familiar with 3D CAD / CAM software, such as UG, Pro / E, etc.; be familiar with NC automatic programming manual programming technology. This kind of personnel needs a lot, especially in the mold industry is very popular, treatment is also very high. Second, the maintenance repair personnel of CNC machine tools: master the mechanical structure electromechanical joint debugging of CNC machine tools, master the operation programming of CNC machine tools, be familiar with the characteristics, software hardware structure, PLC parameter settings of various CNC systems. Proficient in mechanical electrical debugging maintenance of CNC machine tools. The demand for such personnel is relatively small, but it is very difficult to cultivate such personnel, which requires a large number of practical experience accumulation, which is very lacking at present, its treatment is also high.

3. Gold collar layer: it belongs to the CNC processing generalist. It has comprehensive knowledge required by CNC processing operation technicians, CNC programmers CNC maintenance repair personnel, has accumulated a lot of practical experience in practical work, with a wide range of knowledge. Proficient in the mechanical structure design of CNC machine tools the electrical design of CNC system, master the electromechanical joint debugging of CNC machine tools. Be able to complete the selection of numerical control system, the design, installation, debugging maintenance of electrical system of numerical control machine. Can independently complete the numerical control transformation of machine tools. Is the enterprise (especially the private enterprise) the hot talent, its treatment is very high.
