As a manufacturing power, China's machine tool industry has been in a high position in recent years. Before the financial turmoil, this high-growth situation has been maintained for seven consecutive years. During this period, the manufacturing volume of Chinese machine tools also rose from the world's ninth to the world's third, and the output value increased nearly six times. The title of the world factory undoubtedly means a huge market demand. This demand is like a huge thrust. It once pushed the machine tool manufacturing industry to the forefront. It seems that there will never be a stagnant trend.
However, the arrival of the turning point is still inevitable. Whether it is the raging and turbulent financial turmoil or the internal changes in market demand, it has put a severe test on the machine tool manufacturing industry. At this moment, the transformation of the machine tool manufacturing industry is more urgent than ever. The steps of product structure adjustment are started almost simultaneously in various domestic machine tool manufacturing enterprises. Adapting to and responding to market demands as soon as possible under the new situation is the common aspiration of these enterprises.
In fact, product structure adjustment is an important part of the transformation of machine tool manufacturing industry, and the degree of automation of machine tool products has become one of the important factors to distinguish machine tool grades. Advanced automation technology and products will undoubtedly become an important direction for the transformation of the machine tool manufacturing industry, which will be a huge pull for the automation product market. And how will the automation market respond to this questionnaire full of opportunities?
Policy and demand drive the transformation of machine tool manufacturing
It can be seen that after the financial crisis was detonated, the momentum of the machine tool industry has dropped significantly. In reality, however, the market's changes in the demand structure of machine tool products have been subtly occurring before the financial crisis. According to Wu Bolin, Director General of China Machine Tool & Tool Industry Association, from January to September 2008, the machine tool industry increased sales by 32% compared with the same period last year, total output value increased by 31%, and profit increased by 30%. The data still maintains a steady and rapid development, but at the same time it also shows some characteristics.
First of all, the sales situation of domestic machine tool products has undergone major changes. In the case of metalworking machines, sales increased by 32% and production increased by only 2%. This shows that the market for low-end, small-size products has declined, while the market for high-end, high-value-added products has increased. On the other hand, from the perspective of import demand, from January to September 2008, the import value of China's machine tool industry has increased significantly, and the number of imports has decreased. Taking a large number of machining centers and CNC lathes as an example, the price of each imported machining center has increased by an average of 13,000 US dollars, and the average numerical control lathe has increased by 90,000 US dollars. This reflects that the demand for foreign high-end machine tools is not falling. .
In summary, domestic low-end machine tools are gradually experiencing overcapacity. At the same time, domestic enterprises have insufficient production capacity for medium and high-end machine tools, and the trend of demand changes is self-evident. At this moment, the advent of the financial crisis is playing a catalytic role, making the contrast of this situation more obvious. On the one hand, its impact on the manufacturing industry has caused a sharpening of the demand for some low-end machine tools. On the other hand, the series of projects that the country has responded to the financial crisis and expanded the huge domestic investment has once again stimulated the demand for high-end machine tools.
At the same time, the attention of a series of relevant national policies to the machine tool industry has also become another driving force for the transformation of the machine tool manufacturing industry.
Following the "Several Opinions of the State Council on Accelerating the Revitalization of the Equipment Manufacturing Industry", the development of high-end CNC machine tools and basic manufacturing equipment has been incorporated into 16 key points, and the state's attention to the machine tool industry has not stopped. On December 24, 2008, the State Council executive meeting reviewed and approved in principle the “Several Specialized Implementation Plan for High-end CNC Machine Tools and Basic Manufacturing Equipment”.
According to the goal plan, by 2020, China will form the independent development capability of the main products of high-end CNC machine tools and basic manufacturing equipment. The overall technical level will enter the international advanced ranks, and some products will lead the world internationally; establish complete functional parts research and development and supporting capabilities; aviation About 80% of high-end CNC machine tools and basic manufacturing equipment required for aerospace, marine, automotive, and power generation equipment manufacturing will be based in China.
The potential of automation technology highlights the machine tool industry
The degree of automation of machine tool products has a crucial impact on the speed and accuracy of machine tools, and has become an important factor in distinguishing machine grades. Advanced automation technology and products will undoubtedly become an important direction for the transformation of machine tool manufacturing industry, and its development potential will be highlighted in this change.
In machine tool products, especially high-end machine tools, automation technology and products are used in almost every part of the control mechanism, actuators and measurement and feedback mechanisms. Currently, almost all kinds of automation products used in machine tools and machine tool production lines In the midst of new changes. As the control center of medium and high-end machine tools, the numerical control system includes various technologies such as motion control, intelligent technology and self-diagnosis. Multi-axis and multi-system numerical control devices have been developed and put into use. The control method of servo system is gradually From the conventional signal type to the bus type transition; servo drives and motors are also developing in the direction of digitization, communication and intelligence.
In this regard, many cutting-edge automation technology trends have also emerged. For example, the application of linear motors and torque motors is a good example. Most of the gantry rails of Mazak and Mori Seiki are no longer using rolling guides, but instead of linear motors, thk linear motors can reach 720m/min under 3000n load, which is not to be said. A breakthrough. Torque motors were previously only available on small form factor machines and are now available for larger and larger machine sizes. The maturity of these technologies is also constantly improving the performance of machine tools.
Domestic automation industry needs to seize opportunities
Faced with the severe economic situation, the infrastructure industry, which is encouraged and supported by rail transit and electric power, is becoming a hot spot of concern, and the machine tool industry is undoubtedly the beneficiary of the rise of these infrastructure industries. If you can wait for opportunities to seek steady development in this field, it is also a good opportunity to seize the crisis. This is not only for international manufacturers that already have an advantage in the field of automation, but also for some domestic automation companies with potential for growth.
The field of numerical control systems is well represented in this respect. Although in the field of numerical control systems, domestic enterprises have not been dominant, but in the past two years, the market share of domestic CNC systems has been steadily improved. According to the person in charge of the CNC System Branch of China Machine Tool Association, there are 30 to 40 major manufacturers of CNC systems in China, which has formed a scale that cannot be neglected. The development and improvement of products have also made significant progress.
In order to meet the supporting requirements of the numerical control system, the weaker place of the domestic brand has been compensated. A group of enterprises have also developed the AC servo drive system and the AC spindle servo control system, and completed the 20-200a AC servo system and The development of the matching AC servo motor series spectrum has formed a series of products and mass production capacity. And compared with some international manufacturers, many domestic CNC systems can be opened to domestic production enterprises, which is convenient for secondary development, which is also available for competition.
