Abstract

The known on-line roll grinding method is improved so as to avoid clogging of grinder, breaking of a grinder corner portion, complication of a grinder con­ struction and buzzing vibration of a grinder. A plurality of grinder holders adapted to press grinders mounted to their tip end portions against a roll surface, are arrayed along the axial direction of the roll within a frame which can reciprocate along the roll axis. The grinders are mounted within the holders with their rotary axes inclined in the axial direction of the roll with respect to normal lines of the roll surface. The rotary axes of the grinders are displaced by a given offset amount H with respect to the rotary axis of the roll. The improvements reside in that an inner diameter d G and an outer diameter DG of the grinder and the offset amount H are chosen so as to fulfil the following formulae:
0.1 ≦ H/DG ≦ 0.4, and
0.1 ≦ d G/DG.
