Machine tool industry faces industrial restructuring

According to reports, in 2012, China's machine tool industry continued the downward trend that began in the second half of 2011. The growth rate continued to decline slowly and the domestic market was depressed. The demand for domestically produced low-end products has been significantly reduced, and imports have been operating at high levels. The contradiction between product structure and market demand has become more prominent. The military industry, energy equipment and other fields are considered to be an important driving force for the development of China's machine tool industry to high-end development and industrial restructuring.

According to the relevant personages of the China Machine Tool Industry Association, the demand for CNC machine tools in the power equipment manufacturing industry is embodied in the thermal power and nuclear power turbine cylinders, turbine rotors and blades, generator stators and rotors, nuclear heat exchangers and orifice plates. Hydro-generator base stators and rotors require heavy-duty machine tools.

The relevant person in charge of Shaanxi Qinchuan Machine Tool Group Co., Ltd. stated that in addition to the equipment required for traditional energy sources, the rise of new energy industries 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 parts and components and the development of wind power processing equipment.

At present, the overall design and load calculation capacity of large-scale wind turbines in China is relatively weak, and the design and production capacity of control systems, generators, gear boxes, and bearings have a large gap compared with the advanced level in foreign countries. The bearings, control systems, and other keys of fans are critical. 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 realized the important driving force of energy equipment and have begun to actively develop related machine tools. The XKD2755×570-2M numerically-controlled fixed beam double-gantry mobile boring and milling machine independently developed by Wuzhong is suitable for the processing of super-sized components such as wind power gears; the world’s largest heavy-duty TK6932 CNC double-column landing-type milling and boring machine independently developed by Qi 2 Machine is a large hydropower generating unit, The ultra-large workpiece machining of nuclear power plant equipment provides the key processing machine tools.

"On the one hand, machine tools as the parent equipment for equipment manufacturing is the fundamental guarantee for the upgrade of the energy equipment manufacturing industry. On the other hand, the energy equipment industry has a strong pulling effect on the machine tool industry and can help the machine tool industry to optimize and upgrade the industrial structure. The relevant person said.

Under the support of important industries such as energy equipment, the industry structure and product structure of the domestic machine tool industry have seen some promising development trends: For example, new progresses have been made in the production line manufacturing technology and application fields; One of the models, the machining center develops in terms of functions to high speed and precision; the precision machine tool enters the micro-nano era; the intelligent technology is widely used; the industrial robot industry develops rapidly and becomes intelligent manufacturing and industrial automation. The key technologies and important products.
