XM-1800 Rail Milling and Grinding Machine
性能及特點
Adopting the technology of circumferential milling and equipped with the computer monitoring system, the rail milling and grinding machine effectively helps perform copy milling and grinding of the rail and allows reaching the desired effect at one time work. It has the following beneficial effects: extending the rail life after completely eliminating rail defects and failures; improving rail longitudinal regularity and cross-sectional profile quality (reducing rail wear, improving wheel-rail contact geometric state, lowering relative wheel-rail wear); saving rail maintenance and re-use costs; decreasing the working noise; optimizing the operational safety and efficiency of the railway network. It is featured by higher working precision, favorable effect, fewer limits, shorter setup time, smaller environmental influence, and lower working costs.
Rail milling and grinding machine and rail grinding machine have their respective advantages in terms of railway maintenance, and are strongly complimentary to each other. Specifically, in terms of preventive rail trimming, treatment of slightly-defective rails, rail trimming at the inner side of the line, and unusual rail profile grinding, the rail grinding machine is featured by high efficiency and flexible grinding; while in terms of profile restoration for rail maintenance and treatment of seriously-damaged rails, the milling and grinding machine has higher potential, as well as such advantages as enhanced efficiency, and eco-friendly working process featured by less sparkling and convenience for protection.
