REMOVING IRREGULARITIES FORM RAILS

摘要

A continuously advancing rail grinding machine comprises a grinding tool head vertically and laterally adjustably arranged on a mounting linked to the machine frame. A drive is connected to the tool head for imparting thereto a continuously reciprocating working movement superimposed upon the working movement derived from the advancement of the machine along the track, the reciprocating working movement extending in a plane transverse to the track and over a range extending from an end point of the arcuate corner surface at the side surface of the rail head to at least one third of the periphery of the arcuate corner surface. The reciprocating working movement enables rapid and coarse removal of surface irregularities from the rail head.
