Demand for high-end machine tools continues to grow in wind power equipment

Editor's note: The rapid development of China's wind power industry has led to a rapid increase in the domestic level of domestic wind power equipment, and has also driven the rapid development of domestic related industries. Advances in wind power equipment processing technology rely heavily on the advancement and precision of machine tools and tools. Therefore, the wind power industry has continued to improve in recent years, driving the development of China's high-end machine tool industry.

China's wind power industry has continued to improve in recent years. The annual new and cumulative installed capacity has doubled for four consecutive years. In 2010, the installed capacity of wind power ranked second in the world. The rapid development of China's wind power industry has led to a rapid increase in the domestic level of domestic wind power equipment, and has also driven the rapid development of relevant domestic industries. The processing of the main components of wind turbines requires a large number of sophisticated and efficient CNC machine tools and high-end tools. The advancement of wind power equipment processing technology depends largely on the advancement and precision of machine tools and tools. In addition, most of the wind power equipment working environment is relatively harsh, which also puts high requirements on the processing of related equipment. It can be said that advanced equipment manufacturing processes, especially advanced machine tools and tools, are the fundamental guarantee for upgrading the wind power equipment manufacturing industry.

Among the related wind power equipment manufacturing enterprises, both managers and technicians have expressed strong dependence on wind power equipment for advanced processing equipment such as machine tools. At the Beijing Wind Energy Exhibition held in October 2010, Huarui Wind Power's technical staff explained to the reporter some of the process requirements for wind power equipment processing. Taking the gearbox of wind power equipment as an example, it is mainly composed of a box body, a planetary gear train and a shifting mechanism. The gearbox body belongs to a large box body, and its structure is complicated. The processing of various components requires different machine tools and tools to complete. Most of the MW-class wind power equipment gearboxes are split-structured. CNC machining, floor milling and boring machines, large horizontal machining centers and gantry machining centers are required for machining. Large-size, large-modulus gears and ring gears need to be machined using CNC forming and milling machines and CNC forming gear grinding machines. Among them, CNC forming and milling machine requires large depth of cut, large feed and high rolling speed. The precision of CNC forming gear grinding machine is more than 5 grades, and it requires high degree of automation such as automatic centering, automatic measurement and automatic shaping. High stability.

In the case of gearbox processing of wind power equipment, CNC floor milling and boring machine, large horizontal machining center, gantry machining center, CNC forming and milling machine and CNC forming gear grinding machine are all high-end equipment with high technical content in the current machine tool industry. The technicians of wind power equipment manufacturers have clearly stated that the machine tools used by their company are technologically advanced high-end products imported from abroad. This shows that the wind power equipment processing process is extremely high. In an interview with wind power equipment manufacturing companies, the reporter recorded the requirements for machine tools and related processes when processing multiple wind power equipment parts.
