What kind of road should China's high-end precision machining industry take? Self-reliance and technology introduction, two roads are in front of us. We want to build a powerful country in processing and manufacturing. Some people think that high-end precision machining should not take the road of technology introduction, but should take the road of self-reliance. Some people also suggested that it is also a way of thinking that the market should change technology. China has the world's largest spare parts processing market, and the introduction of technology can also catch up.

       From the perspective of China's high-speed rail industry, technology introduction is indeed a good development path. Our high-end CNC precision machining can be stronger first and bigger later. There are many detours, so under the condition of backward spare parts processing technology, if our metal processing enterprises can introduce external technology, they should take advantage of the opportunity and introduce technology for development.

       Since the reform and opening up, my country's CNC precision machining industry has seized the historical opportunity of the global industrial division of labor and achieved great success by introducing technology and opening up in an all-round way. For more than 40 years, the growth of spare parts processing industry clusters in the coastal areas of Guangdong is the best proof. Relying on the introduction of metal processing technology to develop three-to-one-supplement trade, my country has now established a processing technology system of a certain scale and level.

      Importing is not perfect, but also depends on your own digestion and absorption. While seizing opportunities and introducing development, our CNC precision machining enterprises should accumulate strength and engage in independent research and development and independent innovation. A big country in the processing of spare parts cannot always rely on external technologies. It must introduce and re-learn, and finally form its own intellectual property system. The development of the high-speed rail industry is the best example.
