March 4, China Railway Technology Management in conjunction with the Department of Public Works and Transport Bureau in Xi'an organized XM-1800 Rail milling vehicle technology will be assessed. The experts briefed the company related materials, Xi'an Railway Bureau, the views of users, transport assessment and inspection reports on the kind of vehicle quality inspection center, watched the demonstration of the kind of car field operations, the experts unanimously agreed to review. The company independently developed the XM-1800 Rail milling vehicle, able to work on the rail line running on the dynamic milling eliminate rail side wear, corrugation, rolling layer, cracks, peeling or other defects, thereby restoring the rail head designed shape of the working part. Rail milling vehicle can achieve the following objectives: to improve the rail service life, improve rail longitudinal and cross-sectional contour ride quality (reduce rail wear, improve the state of the wheel-rail contact geometry, the relative reduction in the wheel-rail wear), reduce the cost of rail maintenance and reuse costs, reduce operating noise, improve the road network operational safety and operational efficiency. Rail milling vehicle having a rail milling operations and iron filings, debris real-time collection, storage, milling disc with a diameter of 1400mm, replaceable knife holder and knife tablets consisting of milling apparatus, tool holder can be achieved by customizing different profile shape rail milling, advanced level of technology. XM-1800 Rail milling vehicle through technical evaluation, will fill the autonomy rail milling equipment refurbishment blank, shorten the gap with the world advanced technology, provide strong technical support for the application and development of China Railway Rail maintenance equipment refurbishment. With the development of the railway construction speed and high-speed rail, rail milling vehicles rail line will be a serious disease, small curve radius rail line, the line of rail line repair station, human performance and environmental requirements grow high tunnels, subways, Light rail line repair diseases, profile high precision turnouts disease repair line has played a huge advantage, with significant economic and social benefits.
