These processes fall within the scope of general mechanical manufacturing and diesel engine manufacturing, overall. There is a high demand for general-purpose and specialized machine tools, such as large vertical and horizontal machining centers, gantry machining centers, CNC boring and milling machines, CNC vertical lathes, CNC precision grinders, and crankshaft lathes.
In the field of daily railway maintenance services, one of the main job responsibilities is to ensure the integrity of the wheels and axles, timely repair and replace worn wheels and bearings, and repair the axles when replacing bearings. Therefore, this is an essential equipment for CNC wheel lathes, CNC non falling wheelset lathes, and cylindrical grinders.
At the same time, with the deepening of the reform of the railway department and the long-distance operation of trains across bureaus, the workload of maintenance will increase significantly. Maintenance and repair work will be increasingly concentrated in the locomotive and rolling stock depots in hub areas. A production line with a gantry wheel lathe as the core, including ultrasonic testing and wear measurement, and automatically restoring the minimum cutting amount of the prototype, will become the direction of future development.
On track,
The eighth acceleration completed in 2011 marked the beginning of China's rail transit system's first major acceleration. China's rail transit has gone through a rapid development process. Taking Shanghai to Nanjing as an example, the entire journey takes 4-5 hours before acceleration. Currently, the fastest speed in just 1 hour has exceeded 350km/h, and it only takes 5 hours from Shanghai to Beijing. The realization of these highways relies on advanced manufacturing technology and equipment.
The demand for machine tools in the rail transit industry can be roughly divided into four levels: firstly, rail processing and high-speed railway sleeper processing; Secondly, the manufacturing of locomotives and vehicles; The third is the manufacturing of wheels and vehicle components; The fourth is the daily maintenance and repair of operations, based on product and business division of labor. These four aspects almost cover the entire rail transit industry chain, including road network construction, vehicle manufacturing, operation and maintenance. These manufacturing processes urgently require universal CNC metal cutting machines such as machining centers and CNC vertical lathes, as well as specialized CNC metal cutting machines such as track plate grinders and track grinding machines; We also need forming machines such as presses and bending machines.
In terms of track processing and high-speed railway sleeper processing, specifically. The construction and renovation of speed-up and high-speed tracks require new types of speed-up switches, and the demand for CNC switch milling machines and switch grinding machines is constantly increasing.
The high-speed track is laid on track boards that are completely different from sleepers and requires a dedicated CNC track board grinder, which requires a set every 100km. In terms of manufacturing vehicle components, the demand for machine tools varies among power trains, electric locomotives, and electric drive diesel locomotives. The focus of electric locomotive processing is on the motor stator, rotor, and motor shaft, while the focus of electric drive diesel locomotive processing is on the diesel engine, generator, and transmission components.
