When the school chooses the CNC system of CNC machine tools, it must consider the use of some other CNC systems, especially the open CNC system. Under the current conditions, try to achieve a comprehensive mix, and gradually increase the proportion of open CNC systems; schools with better economic conditions can use imported, under normal circumstances, domestically available. A few days ago, when I visited the Beijing Industry and Trade Technician College, the teacher who listened to the CNC training said that there are often factories that can operate Siemens. CNC system students, so they are considering purchasing with Siemens. CNC machine tools for CNC systems, of course, the price is definitely more expensive. Now the price of the domestic open CNC system is equivalent to the price of the system, but its function and performance are basically a grade with the system. In fact, as long as the open CNC system is adopted, it can be conveniently adopted; the communication protocol has an Ethernet interface and is physically networked. This is one of the important reasons why we strongly recommend the active adoption of the sixth generation of open CNC technology. In this standard of equipment, if this factor is not taken into consideration, within a few years, it will be difficult to change the situation in which China continues to lag behind in this field. Seizing this opportunity will greatly change the situation that China's numerical control technology is always backward. It is a step forward from equipment and personnel training to narrow the gap with developed countries. It is the most active change in China's transition from a manufacturing power to a manufacturing power. Initiative.
