The rapid development of science and technology in the world today is gestating a new revolutionary breakthrough. Processing technology has entered the era of sub-micron and nano-scale super-precision processing. Networked manufacturing technology is in the ascendant, green manufacturing is on the rise, and digital manufacturing with CNC machine tools as a technology platform has enhanced the new stage of intelligent manufacturing. Technology integration and technology compounding have become CNC machine tools. One of the most active trends in technology.
As one of the main features of machine tools that distinguishes it from other machines, “precision” has always been the goal of the global machine tool industry. Luo Baihui, chief analyst of Jinmo Machine Tool Network, believes that nano-scale CNC system and servo drive, nano-scale measurement and feedback compensation, high-speed and high-precision trajectory control, high stiffness and high dynamic drive, high stiffness and low inertia structure design, high precision spindle, vibration suppression The increasing use of advanced technologies such as temperature control has pushed modern machine tools into the micro-nano era.
The emergence of the micro-nano era is inseparable from the support of emerging technologies, and the intelligent technology of the machine tool industry is currently applying great results. Intelligentization is a high-level control technology that integrates information technology, system control technology, electronic technology, optoelectronic technology, communication technology, sensing technology, software technology and expert system to achieve expansion or replacement of mental labor. An important technical foundation for digital factories.
The emergence of robots further enhances the level of machine micro-nano, and the rapid development of internal and external industrial robot industry has become a key technology and important product of intelligent manufacturing and industrial automation. It is also an important part of the higher-level CNC machine tool to be automated. Various types of industrial robots and examples of integrated application with machine tools fully demonstrate the current situation of industrial robots, the emergence of new army, rapid development, and the technological advantages and market prospects brought by the combination of CNC machine tools.
Numerical control technology is the core technology of advanced manufacturing technology. Its overall level marks the level of industrial modernization of a country and the strength of comprehensive national strength. It has a strategic material status that transcends its economic value. There is still a long way to go before we can become a machine tool powerhouse.
In 2013, China's machine tool industry continued its development trend in the second half of 2012. The growth rate continued to slow down and the domestic market was sluggish. The demand for domestic low-end products has been significantly reduced, and the import volume has been running at a high level. The contradiction between product structure and market demand is more prominent. The military industry and the field of energy equipment are considered to be an important driving force for the development of China's machine tool industry to high-end and industrial restructuring.
According to Luo Baihui, chief analyst of Jinmo Machine Tool Network, large-scale power generation, power transmission and transformation equipment, large-scale petrochemical and coal chemical plants in the energy field require a large number of heavy-duty, precision, multi-coordinate, high-efficiency, special-purpose CNC machine tools for manufacturing. One heavy, two heavy, Harbin and other energy equipment companies, many large key components must be produced by themselves, and there is a great demand for high-end machine tools.
According to Luo Baihui, the demand for CNC machine tools in the power equipment manufacturing industry is embodied in the steam turbine block, steam turbine rotor and blades of thermal power and nuclear power; generator stator and rotor; nuclear heat exchanger and orifice plate; hydroelectric generator base Both the stator and the rotor require heavy machining.
In an interview with the reporter of China Sankei Shimbun, Luo Baihui said that in addition to the equipment needed for traditional energy, the rise of the new energy industry will expand the application range of mechanical products, thus providing new market opportunities for processing equipment. The most obvious example is the development of the wind power industry for the demand for wind turbines and their components and the development of wind power processing equipment.
At present, the overall design and load calculation capability of large-scale wind turbines in China is weak. The design and production capacity of control systems, generators, gearboxes and bearings are far from the advanced level of foreign countries. The key of bearing and control system of wind turbines Parts also need to be imported from abroad. One of the key factors of the restriction is that our manufacturing process and processing equipment are relatively backward.
However, machine tool leaders have already recognized the important driving force of energy equipment and have begun to actively develop related machine tools. The XKD2755×570-2M CNC fixed beam double gantry mobile boring and milling machine independently developed by Wuzhong is suitable for the processing of large-sized parts such as wind power gears; the world's largest heavy-duty TK6932 CNC double-column floor milling boring machine independently developed by Qi Er Machine Tool is a large hydropower unit. The processing of very large workpieces in nuclear power plant equipment provides key processing machines.
"On the one hand, machine tools as the main machine for equipment manufacturing are the fundamental guarantee for the upgrading of the energy equipment manufacturing industry. On the other hand, the energy equipment industry has a strong pulling effect on the machine tool industry, which can help the machine tool industry to achieve industrial structure optimization and upgrading. Luo Baihui said that under the support of important industries such as energy equipment, the industrial structure and product structure of the domestic machine tool industry have seen some gratifying development trends: for example, new progress has been made in production line manufacturing technology and application fields; One of the main types of large-scale machines, the machining center is functionally compounded, and its performance is developing at a high speed and precision; precision machine tools enter the micro-nano era; intelligent technology is widely used; the industrial robot industry is rapidly developing and becoming Key technologies and important products for intelligent manufacturing and industrial automation.
The relevant person in charge of the National Energy Administration also said that in the process of structural adjustment and technological progress in the energy industry, it can stimulate the technological progress of domestic machine tool products and domestic processing equipment. The machine tool industry can ask energy companies to talk about demand, talk about products to be processed, process technology and requirements, conduct supply and demand docking, and then determine demonstration projects and supporting units.
