<p><P>PROBLEM TO BE SOLVED: To provide a method of grinding a cast piece in which, when the cast piece formed by continuous casting is ground by a rotary grinding wheel, the rotary grinding wheel is not slipped from a ground surface. <P>SOLUTION: When the cast piece is ground along edges 30b and 30c of the cast piece 30 while tilting a rotational axis 32 of the rotary grinding wheel 31 relative to these edges 30b and 30c, the direction of a reaction force R in a moving direction exerted from a portion of the cast piece 30 during grinding is oriented inward of the cast piece 30 with respect to a side surface 31a located downward of the moving direction of the rotary grinding wheel 31. The inward reaction force R relative to the cast piece 30 is achieved by setting an acute angle as an angleαformed between the rotational axis 32 extending outward of the cast piece 30, and the edges 30b and 30c of the cast piece 30 located downward in the moving direction of the rotary grinding wheel 31. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
