1. In recent years, new materials continue to appear, the types of materials proliferate, and the strength, hardness and heat resistance continue to improve. The rapid development of new materials poses new challenges to machining. On the one hand, it forces the ordinary processing method to change the tool material and improve the equipment used; On the other hand, for the processing of special materials such as high-strength materials, extremely hard and extremely brittle materials, it is necessary to apply more modern knowledge of physics, chemistry and material science to develop new manufacturing technologies. Therefore, there are many special processing methods, such as electric discharge machining, electrolytic machining, ultrasonic machining, electron beam machining, ion beam machining and laser machining. These processing methods break through the traditional metal cutting methods and make the machinery manufacturing industry take on a new look.

2. In recent years, the popularity of CNC machine tools and various automatic tool changing machining centers has made the machine tools develop in the direction of high speed and high precision. In the process of machine tool numerical control, the cost of mechanical parts in the machine tool system continues to decline, and the modular, universal and standardized numerical control software makes it easy for users to achieve the purpose of processing.

3 The main task of China’s machinery industry is to provide various advanced, efficient and energy-saving new mechanical and electrical equipment for the development of various sectors of the national economy; Efforts to improve quality, ensure delivery time, and actively reduce costs will raise China’s machinery processing industry to a new level.

  4 Manufacturing industry occupies a very important position in the national economy of many countries, especially developed countries, and is also the pillar industry of the national economy. While 68 percent of U.S. wealth comes from manufacturing, 49 percent of Japan’s national economy is provided by manufacturing. China’s manufacturing sector accounts for more than 40% of its total industrial output. It can be seen that the development level of the machinery manufacturing industry is one of the important signs of measuring a country’s economic strength and scientific and technological level.

5 Machinery manufacturing industry is the main body of industry. Today, it has grown into a huge and all-encompassing industry. Machinery manufacturing is a general term for the manufacturing process of various machines, machine tools, tools and instruments. Machinery manufacturing related products cover home appliances, auto parts, construction machinery, factory equipment and other fields. Mechanical manufacturing technology is the engineering technology to study the processing principles, processes and methods of these mechanical products and corresponding equipment. The machinery manufacturing industry is the foundation and pillar of the national economy, and it is the technical equipment department that provides tools, instruments and various mechanical equipment to other departments.
