With the economic recovery coupled with the acceleration of the speed of industrialization in China, it has a good role in promoting the machine tool industry. The demand for the machine tool industry is very strong. Blowouts occur in small and medium size machine tools. After the Spring Festival, sales in the machine tool industry continued to rise. Small and medium-sized machine tools are particularly popular, and there are blowout phenomena. The phenomenon of out-of-stock products and customer rushing is widespread, and price increases for small and medium-sized machine tools are common. Some of the products that are in short supply have been scheduled for production until the second half of the year, and have even been scheduled for production in 2011.
At the 6th China CNC Machine Tool Show that ended earlier in the period, many companies also stated that the machine tool market is very hot and the supply of machine tools is in short supply. The thick warmth of the Chinese machine tool market has advanced into the fiery summer. The future of CNC machine tool industry can be expected.
Industry Action: Upgrading In progress In 2009, China became the world's largest machine tool consumer and importer for the eighth consecutive year, and for the first time became the world's largest machine tool producer. The data shows that the machine tool industry maintained a good momentum of growth under the joint efforts of the whole industry to accelerate independent innovation and vigorously adjust the structure.
Although the domestic market share of domestic machine tools has been significantly improved, the market share of high-end CNC machine tools and core functional components in the domestic market is still very low, and the potential for the whole industry to replace imports is still huge. Data show that last year, machine tool component imports continued to increase, indicating that the domestic machine tool parts can not meet the requirements of the host industry. Therefore, to further accelerate the adjustment of product structure and promote industrial upgrading is still the top priority for China's machine tool industry. The industrial upgrading of CNC machine tools is still in progress.
Industry decline: The basic consensus for expanding the development of CNC machine tools in high-end areas is toward high-speed, high-precision, precision, compound, intelligent, information, environmental protection, and modular design.
High-speed and high-efficiency: High-speed and ultra-high-speed machining technologies can improve processing efficiency, and are also an important guarantee for difficult-to-cut materials, increase machining accuracy, and control vibration. The key to this technology is to increase the spindle speed and feed speed of the machine tool. For example, the maximum speed, power, and torque of the high-speed spindle are further increased. The sensor technology is used for vibration monitoring and diagnosis. A further light-weight feed system is adopted. The direct drive of the linear motor and the torque motor is adopted, and the tool spindle component realizes three machine tools. Linear coordinate movement.
Precision: Due to the precision of the machine tool structure and the processing of various components, it is not a problem that the machine tool can reach micron-level accuracy. At present, the high-precision CNC machine tool positioning accuracy (full stroke) has reached 0.004 to 0.006mm, and the repeat positioning accuracy is 0.002 to 0.003mm. At the same time, ultra-precision nano-machine tools representing precision have begun to emerge.
Compounding: While the degree of integration of parts and components continues to increase and the number is decreasing, the shape of processed products is becoming more and more complex. Multi-axis controlled machine tools are suitable for machining complex-shaped workpieces. On the other hand, the shortening of the product cycle requires the processing machine to be able to adjust and adapt to new changes at any time to meet the processing needs of various products. This requires that a machine tool can handle processes that previously required several machine tools. Under the premise of maintaining process concentration and reducing the relocation of workpieces, more and more different machining processes are combined on one machine tool to reduce the floor area, reduce the parts transfer and inventory, and ensure the processing accuracy and energy saving requirements.
Intelligent: Modern intelligent CNC machine tools can automatically adjust the working parameters according to changes in cutting conditions, maintain the best working conditions, get higher machining accuracy and lower surface roughness values, and can also increase the service life of the tools. Equipment production efficiency. In addition, the system can also perform self-diagnosis and inspection on the CNC system itself and various devices connected to it at any time to achieve fault shutdown, fault alarms, and indications of locations and causes of failures. The trend of intelligent modern CNC machine tools is to adopt artificial intelligence expert diagnosis system.
Informatization: Using computer technology and network communication technology, machine tool manufacturers can establish a remote machine support system for machine tools to realize the transmission, storage, query and display of operating conditions, and remote intelligent diagnosis. Based on the network connection, the machine tool user can obtain the remote technical support of the machine tool manufacturer in time. The machine tool manufacturer can accurately and effectively obtain the data of the user's machine tool condition data, perform on-line online diagnosis of the machine tool status, and realize the opening of the whole production cycle service of the machine tool. Network monitoring services can improve the efficiency of after-sales services and help improve the quality of products in a timely manner.
Environmental protection: Environmental protection is a prerequisite for machine tool products. Through dry cutting, quasi-dry cutting, hard cutting and other measures to avoid the cooling fluid, lubricating fluid to cause ecological damage to the surrounding environment and the use of fully enclosed enclosures, to avoid completely cutting or splashing fluid is the main two environmental protection requirements.
Modular design: Modular design has been applied in the manufacture of machine tools. The modular design of horizontal, vertical, full series and cross series makes the same two machines look exactly the same, but the function is Completely different, many modules are common. Modular design will be a main thread throughout the entire product design process. Whether it is the trend of machine tool technology development or the requirements of market competition, both the need to reduce costs and the need to improve product quality are required in the development and design of products. Do a good job of modular design. Product production will develop in the direction of social collaboration and specialization. Small and complete models will be eliminated.
