The effect of rail grinding

Before grinding, the surface of the rail under the curve showed an irregular and intermittent block drop phenomenon, and the depth of these blocks was between 4 and 4 mm. At the same time, the top of the rail showed a flat and concave wear pattern, which undoubtedly affected the normal use of the rail. However, after our professional grinding service, these block drop problems have been significantly improved, and the width of the contact light band has been accurately controlled between 30 and 40 mm, showing a more reasonable distribution state. This change not only improves the performance of the rail, but also lays a solid foundation for its subsequent long-term use. In fact, in the subsequent 10 months of use, the lower rail has always maintained a good state, no new block drop phenomenon has occurred, and its profile and performance have been significantly improved.

After professional grinding, the surface of the rail of the lower rail of the curve presents a brand new look. The block drop phenomenon has been effectively controlled, and its depth is controlled within 4 mm, ensuring the integrity and safety of the rail. At the same time, the flat and concave wear patterns of the rail top have also been significantly improved, and the contact light band width is accurately controlled between 30 and 40 mm, showing a reasonable distribution state. This series of changes not only significantly improves the performance of the rail, but also provides a strong guarantee for its subsequent long-term use. In fact, in the subsequent 10 months of use, the lower rail has maintained an excellent state, without any block drop or wear, and its profile and performance have been significantly improved.

After one month of use, the excellent state of the lower rail after grinding has been further consolidated. No new block drop phenomenon has occurred, and its depth remains within 4 mm, verifying the durability of the grinding effect. At the same time, the flat and concave wear patterns of the rail top remain stable, and the contact light band width is still precisely controlled between 30 and 40 mm, showing a reasonable distribution. This series of continuous good performance fully demonstrates the significant effect of grinding treatment on improving rail performance and extending service life.

After three months of continuous observation, the excellent status of the lower rail after grinding is still maintained. No new damage has appeared, and its surface state remains smooth without obvious unevenness. At the same time, the wear morphology of the rail top part remains stable, and the width of the contact light band is still controlled within a reasonable range of 30 to 40 mm, showing a good distribution state. This series of stable performance further confirms the significant role of grinding technology in improving rail performance and extending its service life.
