The construction and transformation of China's railways with high speed and speed and heavy load has entered the “fast lane†of development. According to the Macroscopic Research Institute of the National Development and Reform Commission, China's high-speed railway construction will maintain large-scale investment in the next five years, and the investment will remain at around 700 billion yuan per year, totaling 3.5 trillion yuan. The booming development of China's railway industry is a major positive for the machine tool industry, and it has huge business opportunities. Rail transit has become a very important market for China's machine tool industry. The demand for machine tools is huge. According to the division of products and business, the demand for machine tools in the rail transit industry can be roughly divided into the following four levels: one is track processing and high-speed railway road pillow processing; the second is the manufacture of locomotives and vehicles; It is the manufacture of wheels and vehicle parts; the fourth is the daily maintenance and repair of the operation. These processing and manufacturing are urgently needed for general-purpose CNC gold-cutting machine tools such as machining centers, CNC vertical lathes, etc., as well as special CNC gold-cutting machine tools, such as track-plate grinding machines, rail-grinding machines, etc.; and forming machines such as presses and bending machines are also needed. Taking locomotives and vehicle manufacturing as an example, the two major groups of CSR and CNR, which belong to the Ministry of Railways, only spent 5 billion yuan on machine tool purchases in 2009. If the other three needs are taken into account, the amount of machine tool purchases per year will reach 7 billion yuan by 2012. According to the specific analysis, in the track processing and high-speed railway sleeper processing, the construction and transformation of speed-increasing and high-speed rails require new speed-increasing ballasts, and the demand for CNC ball-web milling machines and ball-turn grinders is increasing. The high-speed track is laid on a track board that is completely different from the sleeper. A special CNC track plate grinder is required, and a set is required every 100 kilometers. In terms of the manufacture of vehicle parts, the demand for machine tools for power parts, electric locomotives and electric drive diesel locomotives is also different. The focus of electric locomotive machining is on the stator, rotor and motor shaft of the motor, while the focus of the electric drive locomotive is diesel engine, generator and transmission parts. In the body part, the body of different rolling stock is basically a steel frame beam structure, which requires partial surface and hole processing. Generally speaking, these processing are in the scope of general mechanical manufacturing and diesel engine manufacturing. There are many requirements for general-purpose machine tools and special machine tools, such as large vertical machining centers, gantry machining centers, CNC boring and milling machines, CNC vertical lathes, CNC precision grinding machines, Crankshaft car, etc. In the field of daily maintenance services of railways, one of the main tasks is to ensure the integrity of the wheels and axles, timely repair and replacement of worn wheels and bearings, and repair the axles when the bearings are replaced. Therefore, this piece is an essential equipment for CNC wheel lathes, CNC non-falling wheel lathes, and cylindrical grinders. At the same time, with the reform of the railway sector and the running of the train across the directors, the maintenance workload will increase substantially. The maintenance and repair work will be more and more concentrated in the locomotive section and the depot of the hub area, including the gantry wheel lathe. Ultrasonic flaw detection and wear measurement and automatic restoration of the prototype's minimum cutting volume will be the future direction. In addition, with the development of China's railway construction, the degree of automation in line maintenance will be higher and higher, and the demand for road maintenance machinery will continue to increase. It is understood that by 2012, 1,000 large-scale road maintenance machines will be added. This is another growth point worthy of attention in the machine tool industry. "Eight immortals across the sea show their ability" The rapid development of China's rail transit industry and the huge demand for machine tool products have attracted the attention of machine tool companies. Many machine tool companies have made a move to strive for a slice of this emerging market. Germany's well-known machine tool company DMG Group, closely linked to the market, is well prepared for the rail transit, energy and other industries that the Chinese government is vigorously supporting. According to reports, DMG125FDduoBLOCK and DMC125FDduoBLOCK of the DMG Group's milling and compounding center have been successfully applied to the engine wheel processing of Zhiqi Railway Equipment Co., Ltd. Zhiqi Railway Equipment Co., Ltd. is a joint venture established by Shanxi Coal Import and Export Group Co., Ltd., Boao Investment Management Group Co., Ltd. and Italy Luqi Ni Railway Products Group. The company has wheel processing lines, axle processing lines, wheelset assembly lines and wheel alignment lines. It is an international professional manufacturer of high-speed railway EMUs. Its products cover the speed of China High-speed Railway Harmony EMUs 200-380. The wheel pair of kilometers and the wheelset of the super high-speed test train with a speed of 400-500 km/h. At present, Zhiqi has 6 DMG milling and turning machining center DMC125FDduoBLOCK; and 1 DMU125FDduoBLOCK; as a production line proficient in wheelset processing. Whether it's large tools or mold making, mechanical, automotive, model, instrument manufacturing, or aerospace industry, DMU/CFD milling and turning complex machining centers will be able to show their talents as long as they are processed in large batches. The gantry structure, which is most suitable for machining large workpieces, is designed as a machine tool to maximize the rigidity of the machine structure. At the same time, the thermal symmetrical structure has a liquid-cooled ball screw drive mechanism and has a cooling feed motor in all the shafts, thus maximizing the degree. The ground guarantees long-lasting precision. The application of DMG machine tool in the processing of Zhiqi motor car wheel can complete the whole machining of turning, drilling, boring and inclined oil hole in one clamping. The structural design of the double exchange table makes the auxiliary clamping time of the workpiece almost zero. The new projects of the depots of the Ministry of Railways, the high-speed rail and EMU repair bases, the new locomotives and vehicles for new locomotives, and the professional railway axle manufacturing enterprises all have large-scale purchases of high-performance CNC axle grinding machines. Domestic machine tool companies are not lagging behind, accelerating the pace of technology research and development. Since August 2009, Shanghai Machine Tool Plant has started to implement the H235 railway special CNC axle grinding machine project. In August 2010, the latest generation of H235 railway special CNC axle grinding machine passed the acceptance and delivery to customers, which became another highlight of the market expansion. In the development process of this grinding machine, the technical research and development department first introduced the automatic adjustment mechanism of the axle taper grinding with independent intellectual property rights in China, and its rotation precision reached 0.005mm or more. This technology successfully solved the axle taper grinding of the axle. High-precision control and greatly improved grinding efficiency; the latest automatic measuring device, the excuse configuration of the automatic production line matching the requirements of the Ministry of Railways, the latest high-efficiency grinding device and the data and information for axle grinding The added application of machine control functions, etc., the comprehensive application of these technologies is the first in the world.
