After the financial crisis in the second half of 2008, due to the shrinking market, the world's machine tool output value, consumption, import, and export have all declined immediately. In the development of machine tool technology, it has inevitably been seriously affected. Fully demonstrated at the two major international machine tool exhibitions in 2009 (EMO in Europe, CIMT in China), exhibitors dropped sharply, exhibits decreased, visitors decreased, machine tool technology innovation decreased, and practical, low prices, and markets needed The development of technology. This is particularly evident on the EMO. Due to the stable development of China's economy, there is still a large demand for the machine tool market, so the impact is lighter. At the two major international machine tool exhibitions in 2010 (IMTS in the US and JIMTOF in Japan), due to the recovery of the world economy, the situation improved. From 2010 Top 10 News of the world's machine tool industry, IMTS, JIMTOF exhibited exhibits and CIMT 2011 Exhibition products, you can see the current world machine tool technology trends have the following three points:
1. The development of high-precision, high-efficiency, high-automation, intelligence, networking, and environmental protection will become the eternal theme of the development of the world's machine tool technology in the future.
As civilian products, military products, automobiles, and aerospace products continue to improve their quality and performance, they urgently need to further develop high-precision, high-efficiency, high-automation, compound, intelligent, networked, and environmentally-friendly methods for processing machines. The level of machine tools has generally increased. The four major international machine tool exhibitions are displayed in four different locations in Europe, the United States, Japan, and China because of their history. The needs, markets, and host countries of different countries have different backgrounds, and the exhibits have their own characteristics. For example, at the EMO exhibition, there were many innovations and developments; at the IMTS exhibition, new processes, new materials, new structures, and difficult-to-cut materials processing machines were the most distinctive; at the JIMTOF show, high-level machine tools from Japan were fully exhibited and displayed. With advanced technology and complete facilities, at the China CIMT Exhibition, there are many advanced and practical products. At the JIMTOF 2010 exhibition, Japan’s Mazak Corporation demonstrated five concepts for the development of new technologies: 1 New Mazak design and ergonomic design techniques; 2 Leading technologies, small batches of efficient processing, diversity, and flexibility Automated technology; 3 intelligent functions; 4 energy conservation, environmental protection; 5 comprehensive support, the most effective investment, can provide comprehensive technical solutions. FANUC Corporation demonstrated its three strategic development directions: 1FA-factory automation; 2RO-robot development and application; 3RM-intelligence. All these are both the current trends in the development of machine tools in the world and will also be the long-term development direction in the future. With the ups and downs of the world economy, it will develop wavy and open up new ideas, new fields and new products.
2. Scientific research is more in-depth and systematic; development and promotion of new technologies are more widespread; new product development is faster, especially in industrialized countries, and the concept of scientific research and innovation is particularly profound and popular.
Research is the source of innovation. Without scientific research, there can be no innovation. As a result, machine tool industry powerhouses and manufacturing powerhouses such as U.S., Germany, and Japan have made great achievements in scientific research and innovation in their IMTS, EMO, and JIMTOF international machine tool exhibitions. New technologies have been rapidly applied and new product development has been fast. . At the JIMTOF 2010 exhibition, Otsuka Innovation researched and developed a “thermal affinity technologyâ€. Through a large amount of test and measurement data for more than 20 years, a complete method for thermal balance of the machine tool structure was developed, and the use of numerical control systems was selected. Set reasonable control points and compensation data to compensate for machine tool machining errors, greatly improving the thermal balance of the machine tool structure, thereby improving the machining accuracy. The breakthrough of this technology and the significant improvement of machine tool accuracy have far-reaching impact on the overall acceleration and development of high-precision machine tools in the future. The positioning accuracy of Japanese machining centers has been able to reach ±2μm, even 1μm. Due to the in-depth, systematic, and constant research innovation, Japan's new product development speed has accelerated. The promotion of high-quality, stable, reliable, and durable SGD components and new technologies is also accelerating. Such as linear motor, direct drive, hardware and software combination, automatic compensation, anti-shake system, four new universal (new materials, new processes, new components, new structures). At the JIMTOF 2010 exhibition, various new products were on display and Mazak exhibited various advanced CNC machine tools. Of the 28 exhibits, 11 are new products. Nine of Mori Seiki's 28 exhibits were new products; FANUC exhibited a highly reliable, cost-effective Φi-D series of new CNC systems, high-speed, high-quality nano-scale 30i/31i/32i- B-Series new CNC system; THK company exhibited precision linear guides with a precision of 23nm/m, circular guideways with a diameter of 2.3m, new linear guides with a length of 7m and so on. At CIMT2011, 10 new production lines were exhibited. These fully demonstrate that, in combination with market demand, the promotion of new technologies and the development of new products will all be greatly accelerated.
3. High-precision machine tools, composite processing machine tools, 5-axis linkage, difficult-to-cut materials processing, and further accelerated development of large-scale micro-machine tools? The structure and parts of the world's manufacturing equipment continue to be high-precision, high-rigidity, high-quality large-scale, miniaturization , Complex development; in the special structure, changes in the material, the market requires more high-precision, composite processing, 5-axis linkage, difficult-to-cut material processing, large-scale micro-machine tools. Therefore, relevant new technologies, new structures, and new products are constantly emerging. In recent years, the demand for heavy machine tools in China has increased and developed rapidly. Japan's 2010 JIMTOF show has grown to become a major feature of the large-scale development. China has many low-middle-range machine tools, and imports a large number of high-grade high-precision, composite machining, 5-axis linkage, and difficult-to-cut material processing machines. The United States has developed a number of special, large-scale, numerically-controlled machine tools, machining centers, etc. after cooperating with Japan in order to develop a spacecraft for Mars.
