·The strength of the grinding stone GS has a significant effect on the sustainable operational capacity and grinding efficiency of grinding car thus probing the effect of grinding stone strength
·The maximum grinding temperature at the same grinding cycle increases with the grain size of grinding stone decreasing shown in Fig 5 c Decreasing grain size of grinding stone means an increase of grinding grain density which results in more intense interaction between the grinding stone and rail specimen So the maximum grinding
·Axial ultrasonic vibration assisted grinding has been widely proved to be effective on the ground quality as well as efficiency for hard and brittle materials However the deference of two typical modes axial ultrasonic vibration assisted peripheral grinding AUPG vibration directions are parallel to the ground surface and axial ultrasonic
·Different types of sandpapers were used to grind surface of 304L alloy and the effects of grinding treatment on surface properties and deformation microstructure were studied Three dimensional profilometer Vickers hardness tester X ray diffraction XRD scanning electron microscopy SEM focused ion beam FIB and transmission electron
