Rail transportation makes the machine tool industry booming

Date of release:2017-12-19 00:00 Source:http://www.tianlaihe.com Click:

China's rail transit has been booming in recent years. Major provincial capitals have owned their own subways. Suzhou has also constructed its own light rail and is currently also constructing the second line. The rail transit industry has undergone a rapid development in recent years. Among them, the construction and renovation of China's railways, which focus on high-speed and speed-raising and overloading, have even stepped into the "fast track" of development.


Rail transport industry demand for machine tools can be divided into four areas, one is rail processing and high-speed railroad pillow processing, the second is the manufacture of locomotives and vehicles, the third is the manufacture of wheels and vehicle parts and components, the fourth is the rail transit locomotive operation Routine maintenance. These four areas cover almost all the rail transit industry chain from the road network construction, vehicle manufacturing, operation and maintenance of rail transportation, the current annual amount of rail transportation industry for machine tool procurement nearly 70 billion yuan. Obviously, the rail transit industry has become a very important emerging customer base in China's machine tool market today.




For example, the first six speed-up locomotives of China's railways are mainly DF-G diesel locomotives based on CSRs. In the recent two years, the speed-raising of railways mainly focused on electric locomotives. However, diesel locomotives still have an irreplaceable status, especially in speeding freight locomotives.


 


    The rapid development of rail transit does bring new development opportunities to the machine tool equipment industry and the corresponding tool industry. In April 2012, MM "Modern Manufacturing" magazine held the 8th China International Metalworking Summit in Nanjing. The theme of the summit was to take the overall solutions era as an occasion, provoking a lively discussion among experts and scholars from all walks of life.




The development of the rail transit industry and machine tool manufacturing industry can be described as complementary and mutually reinforcing. Green and diversified, low noise, less pollution, low fuel consumption, low emissions and high reliability are the goals of the machine tool manufacturing industry. I believe that the prospects for rail transit and machine tool manufacturing in our country will be brighter because of mutual promotion and development.




The rapid development of rail transit can not do without advanced manufacturing technology and equipment




China's rail transit starts with the first large-scale speed increase and completes its eighth speed-up in 2011. China's rail transit has undergone a rapid development. Shanghai to Nanjing, for example, the whole speed to 4 ~ 5h, the fastest now only 1h, the speed has exceeded 350km / h; from Shanghai to Beijing only 5h. These high-speed realization, can not do without advanced manufacturing technology and equipment.




Specifically, in the field of rail processing and high-speed rail sleeper processing, the construction of new speed-raising and high-speed rails and their modification require new speed-increasing turnouts, and the demand for CNC switchmills and turn-point grinding machines is on the rise. High-speed track laying in the track board completely different from the sleepers, the need for special CNC track grinder, about every 100km need to configure a set. In the manufacture of vehicle parts, the demand for machine tools is also different for the power section, electric locomotive and electric drive diesel locomotive. The focus of electric locomotive processing is the motor stator, rotor and motor shaft, etc., while the electric drive diesel locomotive processing focuses on diesel engines, generators and transmission parts. Body parts, different locomotives and vehicles of the car body is basically a steel frame structure, the need for local surface and hole processing.




These processes belong to the general machinery manufacturing and diesel engine manufacturing range, versatility and special needs of machine tools such as large vertical processing center, gantry machining centers, CNC boring and milling machine, CNC vertical lathe, CNC precision grinding machines and crankshaft cars. In the field of routine railway maintenance services, one of the main tasks is to ensure the integrity of the wheels and axles, repair and replace the worn wheels and bearings timely, and repair the axles when replacing the bearings. Therefore, this piece of CNC wheel lathe, NC does not fall on the lathe and cylindrical grinder are all necessary equipment.
