Next, the mode of use and operation of the above-configured embodiment will be described. The shape of the base material W formed at the time of steel making has various shapes such as a long pillar material having a square cross section or a rectangular plate material having a rectangular cross section, but the square cross section is received by one loading device 45. The grinding operation of the supplied substrate W is performed as follows. That is, in FIG. 5, the base material W placed on the carry-in device 45 as shown in FIG. 5A is sequentially supplied onto the roller 21 by the operation of the feeding arm 49 in the forward movement cylinder 48. The supplied base material W is conveyed by the rotation of the roller 21 (FIG.
