Rail grinding is to remove rust, oxidation and dents on the surface of the rail, and to repair burrs and irregularities that may occur during the cutting process. Grinding the rail can improve the surface hardness and smoothness of the rail, reduce the friction with the wheel, and extend the service life of the rail. A common grinding tool is a grinding wheel, which can choose different abrasive grains and hardness according to the material and surface conditions of the rail. When grinding the rail, it is necessary to control the grinding force and speed to avoid excessive grinding causing the rail surface to wear and shape changes.

The selection and use of the rail cutting and grinding wheel is very important for the cutting and grinding effect of the rail. Choosing the appropriate grinding wheel material, particle size and shape can improve work efficiency and quality. Common grinding wheel materials include alumina, silicon carbide and boron nitride, and different materials have different characteristics and scope of application. When using the grinding wheel, it is necessary to pay attention to the balance and fixation of the grinding wheel, as well as the service life and replacement cycle of the grinding wheel. Regular inspection and maintenance of the grinding wheel can ensure the effect and safety of rail cutting and grinding.

In short, rail cutting and grinding wheels are important rail maintenance tools, which can improve the quality and service life of rails. When cutting and grinding operations, it is necessary to pay attention to safety and technical requirements, and select suitable grinding wheels and tools to ensure the work effect and work quality. At the same time, regular inspection and maintenance of tools and grinding wheels can extend their service life and reduce maintenance costs.
