Recently, Hangzhou Machine Tool Group Co., Ltd. and the China Railway Second Bureau and other three user units signed an agreement to obtain the CRTSII track plate CNC special grinding machine orders for the Beijing-Shanghai high-speed railway. The price of a single machine tool and the amount of a single contract reached a historical record, with a total sales amount of nearly 40 million yuan.
The special grinding machine for track plate CNC is used for the grinding of the Borg ballastless track plate bearing table. The development of this is very difficult. Only the German Borg company can manufacture such machine tools. The machine adopts a viaduct type gantry structure with a beam span of about 7 meters. It has 3 stations and servo engraving axes. The number of servo control axes is up to 14. The left and right grinding heads are processed at the same time, and the internationally advanced laser is used online. Detection technology, etc.
Zhu Jingen, chairman of Hangji Group, said that after undertaking the development task of the special grinding machine for track plate CNC, the group will adhere to the localization road, set up a project team, use advanced technology resources at home and abroad for development, and complete research and development tasks according to quality, on time and in quantity. .
Background reading:
The Beijing-Shanghai high-speed railway passenger dedicated line with a total investment of 220 billion yuan has been opened. The length of the whole line is more than 1,300 kilometers and the design speed is 350 kilometers per hour. It is expected to be officially put into operation in 2013. The Beijing-Shanghai high-speed railway will be paved with ballastless tracks and seamless lines. In order to improve the smoothness, stability and safety of the line and meet the needs of high-speed trains, the Beijing-Shanghai high-speed railway passenger line is not laid on ordinary sleepers. Instead, it is laid on a track plate that is precisely ground by a machine tool. The accuracy of the track plate is high, and the error is within 0.1mm.
In order to further expand domestic demand and promote steady and rapid economic development, by the end of 2010, the state plans to invest 4 trillion yuan, including 1.8 trillion yuan for infrastructure investment in railways, highways and aviation. At present, there are 150 railway key projects under construction throughout the country; the planned railway mileage will reach 100,000 kilometers in 2010, including the newly built 7000-km passenger dedicated line and 12,000 kilometers by 2020. Most of the passenger dedicated lines are high-speed railways, so the demand for track-plate grinding machines will become larger and larger, and the market prospects are very broad.
