Grinding machine is an important sub-industry of metal cutting machine tools, referring to machine tools that utilize abrasives to grind and process the surface of a workpiece. According to the different control methods used in grinding machines, grinding machines are categorized into CNC grinding machines and non-CNC grinding machines. CNC grinding machines represent the development trend of the grinding machine industry.

CNC grinding machine is a product of the combination of information technology and mechanical manufacturing technology after the third industrial revolution. As the basic tool of modern mechanical processing, CNC grinding machines are widely used in the automotive industry, consumer electronics, shipbuilding industry, aerospace, national defense industry, electric power equipment, railroad locomotives, construction machinery and other important areas of national economic development. With the development of science and technology, the downstream industry on grinding processing performance and accuracy requirements are increasingly high, the product replacement is increasingly frequent, the type of production from the large volume of a single production gradually to the transformation of multi-species small batch production, the various types of high-precision, high-efficiency, high-flexibility and high degree of automation of CNC grinding machine demand continues to grow.

(1) CNC grinding machine has become the dominant product in the grinding machine market, and the scale of the industry continues to expand.
The development of CNC grinding machines in China began in the mid-1970s. In recent years, with the rapid development of the national economy, China's grinding machine market demand structure has changed significantly, leading the industry development direction of CNC grinding machine demand is growing. On the one hand, the development of China's automobile industry, consumer electronics, shipbuilding industry, aerospace, defense industry, electric power equipment, railroad locomotives, construction machinery industry provides a broad market for CNC grinding machine, on the other hand, and constantly on the CNC grinding machine in terms of quantity, quality, and level of higher and newer requirements to promote the rapid development of CNC grinding machine industry.

According to the China Machine Tool Industry Yearbook, the CNC rate of grinder output value reached 51.75% in 2015, an increase of 5.07 percentage points over 2014. And at present, the numerical control rate of output value of CNC machine tools in developed countries has reached more than 80%, so the development of CNC machine tools in China still has greater potential.

(2) Enhancement of independent innovation ability and technical level improvement
In recent years, China's CNC grinding machine industry has increased the development of new products, the enterprise's scientific research, design, manufacturing capacity continues to strengthen the industry's overall technical level to further improve the product structure to further optimize the success of the development of a large number of new products with a higher level of technology has been initially formed to participate in international competition. According to the statistics of China Machine Tool Industry Yearbook on the main grinding machine enterprises included in the scope of statistics, 28 enterprises in the CNC grinding machine industry developed a total of 97 kinds of new products in 2013, an increase of 3.2% over the previous year, of which 57 kinds of new products of CNC grinding machine, and some of them have reached the international advanced level in terms of new product technology.

(3) There is still a more obvious gap with developed countries, and there is more room for development in the field of high performance.
Overall, Germany, the United States, Japan in the field of CNC grinding machine technology research and development level in the global leading position. As the CNC grinding machine requires very complex processing accuracy and manufacturing process, involving software development, precision manufacturing, electrical control, system integration, and other related services.
Because the processing precision and manufacturing process required by CNC grinding machines are very complex, involving software development, precision manufacturing, electrical control, system integration and other factors, the industry is mainly distributed in the above countries and regions with a higher level of scientific and technological development.

Although China in 2009 has jumped to the world's first big machine tool producer, but the gap with the developed countries is still obvious, high-performance CNC grinding machine is still heavily dependent on imports. The gap between China's CNC grinding machines and developed countries is mainly manifested in: first, the weak technical research and development capabilities, China's production of CNC grinding machines are still mainly low-end traditional products, high-performance and precision high-grade products in the basic research and development capabilities are insufficient to meet the large-scale core components, high-precision product processing requirements; second, the CNC system and the function of localized components lagging behind the functional parts of the supporting capacity of weak, key core components still need to be imported. Secondly, the CNC system and functional localized components lag behind, and the supporting capacity of functional components is weak, the key core components still need to be imported; thirdly, insufficient investment in the development of large-scale, intelligent and composite products, and insufficient reserves for the future development trend of the technology; fourthly, the personalized solutions and service capabilities are weak.

The above gaps are the driving force and market space for the overall improvement of China's CNC grinding machine industry. With the steady growth of China's economy, industrialization and the deepening of the information process, the adjustment and upgrading of industrial structure, the development of high-end equipment manufacturing industry, especially the state attaches great importance to the CNC grinding machine industry as one of the workhorses of the equipment manufacturing industry and the pillar industry will usher in a good opportunity to raise the nature of the intelligence and a broad space.
