Due to the complexity and huge of CNC technology system, CNC system is a high-tech electronic industry with software and hardware research and development content. It requires a large capital and technical strength, which can not be supported by each family. If the investment is carried out rashly, it will not be able to support in the future, which will easily lead to the loss of human and financial resources. Therefore, the government's guidance is necessary. It's the same with the production, study and research of [u]CNC machining[/u], and it's also the same with the research of functional components.
At present, the CNC machine tools produced in China can be roughly divided into three types: economical machine tools, popular machine tools and high-grade machine tools. Economic machine tools are basically open-loop control; popular machine tools use semi closed-loop control technology, the resolution can reach 1 micron; high-grade machine tools use closed-loop control, with high precision, high speed, composite, with a variety of compensation functions, new control functions, automatic diagnosis, the resolution can reach 0.1 micron, the computer can replace human programming.
Industrial automation is the basis of realizing "industry 4.0", and the most representative index of industrial automation is the popularity of robots. At present, there are only 21 robots per 10000 people in China, which is far from developed countries such as Japan and South Korea, and also far from the global average of 55 robots per 10000 people. Therefore, accelerating the development of industrial automation is an important task for China's processing and manufacturing industry It's urgent.
In recent years, China's manufacturing and processing industry has developed by leaps and bounds. Supported by the huge demographic dividend, China became the world's largest country in goods trade in 2013, and won the title of "world factory". However, with the gradual disappearance of the demographic dividend, China's manufacturing and processing industry has also fallen into a transformation dilemma; At the same time, developed countries such as the United States and Germany have launched various support and stimulus policies to develop their own manufacturing industry. China's manufacturing and processing industry is forced to seek changes in order to maintain the advantages of China's manufacturing and processing industry in the future. At this time, the birth of the concept of "industry 4.0" just points out the direction for China's manufacturing and processing industry.
