To provide a grinding method and a grinding device of a slab capable of precisely recognizing a shape of the slab and providing a favorable grinding surface state even on the slab diagonally arranged on a carrier passage with respect to the carrying direction or slab edges of both sides in the cross direction which is not rectilinear.
The grinding method includes steps of: picking up an image of the slab 17 carried in the X direction from above and to measure its shape; measuring a distance to both side surfaces in the cross direction of the slab 17 along its overall length by using a pair of distance measuring means arranged at prescribed distance positions at the outside in the cross direction of the slab 17; detecting an abnormal value included in data of the distance measured by the distance measuring means and to correct it by using data of the shape of the slab 17; and carrying out the chamfering work of the edge by controlling a grinding wheel free to move in the X direction and in the Y direction orthogonal with the X direction by using the corrected data of the distance.
