Rail grinding machine for grinding rails of a track

The present invention refers to a rail grinding machine for grinding rails of a track, and in particular to a rail grinding machine of a type having a machine frame supported by rollers for mobility on both rails and associated with a grinder adjustably secured to a carrier frame in the area of one rail, with the carrier frame together with the grinder being swingably mounted to the machine frame for rotation about a

Experimental investigation on material removal

2020-3-1  Rail grinding is essentially the process of abrasive cutting accompanied by high thermal and mechanical stresses. A large amount of heat generated in the shear zone was transferred into the ground rail, resulting in a series of physical and chemical changes of rail material. As shown in Fig. 15a, the spherical material is observed on the ground rail. As mentioned above, the spherical material is
