The rapid development of wind power in China creates opportunities for the machine tool industry
Knitted Bed Blanket
This Knitted Blanket can be used instead of a quilt to cover the body in the less cold seasons such as spring, summer and autumn to prevent catching cold when sleeping. It is lighter and thinner than a quilt, so there is no sultry feeling. The high-quality wool fabric is also very soft and skin-friendly, and has a comfortable feeling. In winter, you can spread it on the quilt to make the quilt feel warmer.

In order to meet the development of the national economy, the power industry will maintain a certain growth rate. The introduction of government policies and the adjustment of energy structure have created new market opportunities for the machine tool industry while expanding the market space for energy equipment manufacturing. At present, the new energy industry throughout the country is developing rapidly.
Recently, China's first set of large-scale wind turbine core component processing machine was officially offline in Heilongjiang Qizhong CNC, marking China's implementation of localization of large-scale wind turbine core component processing machine tools. Luo Baihui, head of the International Die & Metals and Plastics Industry Suppliers Association, said that with the sound development of the wind power equipment manufacturing industry, the demand for high-end CNC machine tools will have a double increase in quality and quantity, and the technology of the wind power equipment manufacturing industry will be further developed. The breakthrough of the machine tool, the advancement and accuracy of the machine tool are indispensable, which means that the Chinese machine tool industry will be more broad and higher-demand development.
The gearbox of wind power equipment is mainly composed of a box body, a planetary gear train and a transmission mechanism. The gearbox body belongs to a large box body, and its structure is complex. The manufacture of various components requires different machine tool equipment for processing. CNC floor milling and boring machines, large horizontal machining centers, and gantry machining centers require high machining accuracy. Large-size, large-modulus gears and ring gears need to be machined using CNC forming milling machines and CNC forming grinding machines. The processing of large blades requires CNC milling machines. These machines belong to large-size light non-metal five-axis machining machines. Although the machining accuracy is not high, the power and torque are also small, but the requirements for the cutting speed of the machine are very high, and the cutting speed is high. 30 meters/minute or more. Spindles, wind turbines and towers are all large-scale components, which are difficult to process and require high precision. Specially designed special processing equipment is required, and it is both high-speed, high-efficiency, intelligent, flexible, automatic CAD/CAM conversion, and automatic Detection, error compensation and automatic fault diagnosis and many other advanced features.
For a long time, the above-mentioned processing equipment basically relied on imports to solve, causing the cost of wind power equipment to rise. With the continuous improvement of the industrialization level of wind power equipment, the proportion of domestic production has increased rapidly, which has promoted the rapid development of the wind power market and also provided new opportunities for the machine tool industry. In recent years, for the processing of components in the wind power industry, China's machine tool industry is actively developing some processing equipment with independent intellectual property rights, and its processing accuracy, efficiency, and stability are comparable to those of imported equipment.
In 2010, China's machine tool industry was in good condition, with overall production and sales booming. Although various economic indicators fluctuate slightly, they all have larger increases. The development of the shipbuilding, wind power equipment and other industries in the downstream industries of machine tool manufacturing has a greater impact on the machine tool industry. At present, the rapid development of China's wind power industry has led to a rapid increase in the domestic level of domestic wind power equipment, driving the development of China's high-end machine tool industry. However, the development of the state-owned shipbuilding industry is still grim and the market competition is becoming fiercer. In particular, it is difficult to ship, difficult to ship, and difficult to raise financing. The large capacity, low operating rate, and product homogeneity have also triggered low-price competition. In addition, the state-owned shipbuilding industry is still facing a severe test of structural adjustment and fierce competition from major shipbuilding nations in the world. Therefore, in the face of the current state of the shipbuilding industry, we must recognize the situation and we must not be blindly optimistic. In 2011, the machine tool industry must make clear its main direction, further accelerate structural adjustment and change the mode of development to create conditions and environment for the healthy and sustainable development of the industry.
Wind power equipment demand for high-end machine tools to maintain growth China's wind power industry continued to improve in recent years, the annual increase and cumulative installed capacity doubled for four years in a row, wind power installed capacity in 2010 jumped to second in the world. The rapid development of China's wind power industry has promoted the rapid increase in the domestic level of domestic wind power equipment and has also led to the rapid development of domestic related industries. The processing of the main components of the wind turbine requires a large number of sophisticated and efficient CNC machine tools and high-end tools. The advances in processing technology of wind power equipment largely depend on the advancement and precision of machine tools and tools. In addition, most of wind power equipments are in poor working conditions. This also imposes higher requirements on the processing of related equipment. It can be said that advanced equipment manufacturing processes, especially advanced machine tools and cutting tools, are fundamental guarantees for the upgrading of wind power equipment manufacturing industry.
In the transmission case of wind power equipment, CNC floor-level milling and boring machines, large-scale horizontal machining centers, gantry machining centers, CNC forming milling machines, and CNC forming grinding machines are high-end equipment with relatively high technological content in the current machine tool industry.
China's shipbuilding industry reduced demand for heavy machine tools From January to December 2010, China's shipbuilding capacity was 65.6 million dwt, an increase of 54.6% year-on-year, of which seagoing vessels were 20.78 million corrected gross tons, and new orders for vessels were 75.23 million dwt. In the same period last year, the number of new orders received was 2.9 times, of which sea vessels were 22.9 million corrected gross tons. As of the end of December, orders for hand-held vessels amounted to 195.9 million dwt, which represented a 4.1% increase over hand-held orders at the end of 2009, among which seagoing vessels accounted for 59.95 million corrected gross tons and export vessels accounted for 84.6% of the total.
As an important client of the machine tool, the ship supporting equipment (medium and low speed diesel engine, crankshaft, propeller, deck machinery, etc.) industry has made great progress during the "Eleventh Five-Year Plan" period, and many projects have been newly built and expanded. However, the funds for these projects have basically been put in place, and orders for key processing equipment for heavy-duty (including super heavy-duty) machine tools have been basically completed. Obviously, in 2011, orders for heavy-duty machine tools will be significantly reduced in the ship equipment industry, and there will be new demand for other types of machine tools.
