ABSTRACT OF THE DISCLOSURE A tangential grinding machine, particularly for railway rails, comprising a rotating member, a plurality of abrasive sectors mounted on supports radially movable on said rotating member, elements which radially move said supports in order to move said abrasive sectors outwards by an extent which compensates their wear, and a plurality of sensors which when a predetermined degree of wear of the abrasive sectors is attained are activated to act under the control of an electronic unit on the radially movable supports, in order to restore the original grinding surface of the abrasive sectors which have undergone wear, characterised in that between the rotating member provided with abrasive sectors and the machine structure slidable on the rail there is interposed an articulated frame provided with means which cause said rotating member to undergo transverse oscillations about a longitudinal axis substantially coinciding with the axis of curvature of the corresponding band of the rail to be ground.
