PURPOSE:To perform easily and surely the surface quality control of a rolling product by changing the pressing force onto a rolling roll of a grinding body simultaneously with the movement and by making the grinding quantity of non-plate passing part much more compared to a plate passing part. CONSTITUTION:Plural grinding bodies 6, 6C, 6R being arranged along the axial line of a rolling roll 4 are pressed onto the surface of the rolling roll 4 with energizing by respectively separate presser mechanism 7L, 7C, 7R, also the surface of the rolling roll 4 is ground with the reciprocating movement in parallel to the axial line of the rolling roll 4 by driving the grinding body with a driving mechanism. In this case the presser mechanisms 7L, 7C, 7R are controlled simultaneously with the movement of the grinding body so that the grinding body located at the stepped part 4C being formed on the surface of the rolling roll 4 by a plate passing, namely the press force of the grinding bodies 6L, 6R is made bigger compared with the press force of the grinding body 6C of the other part of the surface of the rolling roll. |
