The machine tool industry should aim at the "big cake" in the rail transit market

China's railway construction and renovation with emphasis on high speed, speed, and heavy load has already entered the "fast track" of development. According to the Macro 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 be maintained at about 700 billion yuan per year, totaling 3.5 trillion yuan. The vigorous development of China's railway industry is of great benefit to the machine tool industry, and it contains huge business opportunities. Rail transit has become a very important market for China's machine tool industry.

Machine tool demand potential is huge According to the product and business division of labor, the rail transit industry's demand for machine tools can be roughly divided into the following four levels: First, the rail processing and high-speed railway pillow processing; followed by the manufacture of locomotives and vehicles; third It is the manufacture of wheel and vehicle parts; the fourth is the daily maintenance and repair of the operation. These processing and manufacturing all urgently require general-purpose CNC cutting machine tools such as machining centers, CNC lathes, etc. They also need special CNC gold-cutting machine tools, such as track plate grinders, rail grinding machines, etc., as well as forming machines such as presses and bending machines.

Taking locomotives and vehicles manufacturing as an example, the two large groups of CSR and CNR, which are part of the Ministry of Railways, have spent as much as 5 billion yuan on machine tool procurement in 2009 alone. If the other three requirements are taken into account, the annual amount spent on machine tool purchases by 2012 will reach 7 billion yuan.

Specifically, in terms of track processing and high-speed railway sleeper processing, the construction of speed-increasing and high-speed rails as well as transformations require new types of speed-increasing turnouts, and the demand for numerical control turntables and milling machines and turnout grinders continues to rise. The high-speed track is laid on a track board that is completely different from the sleeper and requires a special CNC track-plate grinding machine, which needs to be arranged about every 100 kilometers. In terms of the manufacture of vehicle parts, the demand for machine tools varies among power units, electric locomotives and electric locomotives. Electric locomotive processing focuses on the motor stator, rotor and motor shaft, etc., while electric transmission diesel locomotive processing focuses on diesel engine, generator and transmission parts. In the body part, the body of different locomotives and vehicles is basically a steel framed beam structure, which requires the processing of partial surfaces and holes. In general, these processes fall within the scope of general machinery manufacturing and diesel engine manufacturing. There are more general-purpose machine tools and special machine tools, such as large-scale vertical and horizontal machining centers, gantry machining centers, CNC boring and milling machines, CNC vertical lathes, and CNC precision grinding machines. Crankshaft cars. In the field of daily 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 in time, and repair the axles when replacing the bearings. Therefore, this piece is a necessary equipment for CNC wheel lathes, CNC falling wheels, lathes, and cylindrical grinders. At the same time, with the deepening of the reform of the railway sector and the operation of the train heads, the maintenance workload will increase substantially, and maintenance and repair work will increasingly focus on the depots and depots in the hub area. The core of the gantry wheel lathes includes: Ultrasonic flaw detection and abrasion measurement and automatic recovery of the prototype minimum cutting capacity of the production line will become the direction of future development.

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 also continue to increase. It is understood that by 2012, an additional 1,000 large-scale road maintenance machinery will be added. This is another growth point that the machine tool industry is worth paying attention to.

"Eight Immortals across the sea show their energy."

The rapid development of China's rail transportation industry and the huge demand for machine tool products have attracted the attention of machine tool companies. Many machine tool companies have made moves and strive to gain a share in this new market.

The German well-known machine tool company DMG Group, closely following the market, has already fully prepared for the rail transportation, energy and other industries that the Chinese government vigorously supports. It has been revealed that the DMU125FDduoBLOCK and DMC125FDduoBLOCK milling and compounding centers of the DMG Group have been successfully applied to the machining of the wheels of the trains of Zhiqi Railway Equipment Co., Ltd. Zhiqi Railway Equipment Co., Ltd. is a joint venture set up by Shanxi Coal Import & Export Group Co., Ltd., Boao Investment Management Group Co., Ltd. and Italy Luqini Railway Products Group. It was established in 2007. The company has wheel processing lines, axle processing lines, wheel assembly lines and wheel pair inspection lines. It is a professional international manufacturer of high-speed railway EMU wheel pairs. Its products cover the speed of the China High Speed ​​Railway Harmony EMU from 200 to 380. The wheel pair of kilometers, and the wheel pair of super high-speed test train with the speed of 400-500 kilometers per hour. At present, Zhiqi has six DMC milling and milling machining centers DMC125FDduoBLOCK and one DMU125FDduoBLOCK; as a production line proficient in wheelset processing. Whether it is a large-scale tool or mold manufacturing, machinery, automobile, model, instrument manufacturing, or aerospace industry, the DMU/CFD milling and machining center will show its capabilities as long as it is a large-scale workpiece. The gantry structure, which is most suitable for machining large workpieces, is used as the machine tool design. It embodies the rigidity of the machine structure to the greatest extent. At the same time, the thermal symmetry structure has a liquid-cooled ball screw drive mechanism and a cooling feed motor in all axes. Guaranteed long-term accuracy. The application of the DMG machine tool in the processing of the Zhiqi EMU wheels enables the complete machining of turning, drilling, boring and tilting oil holes in a single clamping. The design of the double exchange table is such that the auxiliary clamping time of the workpiece is almost zero.

New construction projects for the depots under the Ministry of Railways, maintenance bases for high-speed railways and EMUs, new locomotives and vehicles for locomotive factories, and professional railway axle manufacturing companies all have large-scale procurement of high-performance CNC axle grinding machines. Domestic machine tool companies do not lag behind and accelerate the pace of scientific and technological research and development.
