-- ABSTRACT -- Improved rail grinding apparatus for correcting flatness errors in the slew bearings of large earthmoving machines is disclosed. The grinding apparatus includes a grinding wheel (22) rotated by a motor (24) and forced against a rail (13) by lead screws (28). The latter are controlled by means of displacement sensors (31) and associated control means (33 and 34) so as to grind a profile along the rail (13). The displacement sensors follow guide rails (29) which conform to the desired profile to be ground along the rail (13). The control means (33) may be interfaced with suitable computing means to modify the displacement of the lead screws (28) relative to the guide means (29).
