<P>PROBLEM TO BE SOLVED: To provide a grinding method by which the excessive grinding of the surface of a base material at the periphery of a bead can be prevented and a grinding width can be made small. <P>SOLUTION: The grinding method includes a grinding device preparing step and first and second grinding steps. Since a contact part of a grinding belt 29 is made horizontal and a non-contact part of the grinding belt 29 is easily separated from the curved base material when the reverse V-shaped grinding belt 29 is made to abut on a flat surface 39 obtained by grinding a part of a bead 16 in the first grinding step in the second grinding step, the excessive grinding of the surface of the base material 37 at the periphery of the bead 16 can be prevented. Since the grinding belt 29 grinds only the flat surface 39 in the second grinding step, the grinding width W2 can be made small. Thereby the excessive grinding of the surface of the base material 37 at the periphery of the bead 16 can be prevented and the grinding width W2 can be made small. <P>COPYRIGHT: (C)2013,JPO&INPIT |
