Auto parts

Economic development has accelerated in recent years. The automobile processing industry has also got a good development space and maintained a good momentum of development, so the processing and manufacturing technology of automobile parts has also developed rapidly. Numerical control technology has obvious advantages in multi-category processing and production. It can process various mechanical components, as well as automotive sheet metal, chassis welding, shaft forging, vehicle assembly, electric spark, laser and other special processing. Therefore, it has a particularly important position in the automobile manufacturing industry.

Aviation field

With the progress of science and technology, the requirements for large-scale parts processing, the complexity of parts materials and the accuracy of parts in the aviation field are getting higher and higher. The technology of CNC machine tools in our country is becoming more and more mature. It has high stability and high precision in the processing process, and can process different sizes of material parts. These specific advantages have promoted its wide application in the aviation field.

Metal working

Nowadays, the demand for industrial development in China has been faced with the fact that it can not be realized through the ancient metal material processing technology. Faced with the expansion of the industrial market and the emergence of new materials, there is an urgent need to improve the processing level, and metal material processing has a strong vitality by virtue of CNC processing technology. The application of numerical control technology realizes automatic processing, which can not only reduce the labor intensity of people, but also ensure the high quality and low cost of processing.

Rail Transit

The rail transit industry has experienced a rapid development process in recent years. Among them, the demand for machine tools in rail transit industry can be roughly divided into four aspects, the first is track processing and high-speed railway sleeper processing, the second is locomotive and vehicle manufacturing, the third is wheel and vehicle parts manufacturing, and the fourth is the daily operation of locomotives in rail transit industry. At present, the annual amount of machine tool procurement in rail transit industry is close to 7 billion yuan. Obviously, the rail transit industry has become a very important emerging customer base in today's machine tool market.

Plastics machinery

Compared with metal, stone and wood, plastic has the advantages of low cost and strong plasticity, and is widely used in the national economy. The plastic industry occupies an important position in the world today, and the production of plastic products has developed rapidly all over the world for many years. China's output of plastic products has always been in the forefront of the world rankings. As China has become the world's largest producer of plastic products, numerical control machine tool technology has been used more and more in plastic machinery. The application of numerical control not only reduces the labor cost, but also improves the product quality and production speed.
