PURPOSE: A method for manufacturing a pressed product with the minimized radius of curvature at corners is provided to simplify initial setting and improve workability by cutting one side of a pressed product with surface friction of a grinding member. CONSTITUTION: A method for manufacturing a pressed product with the minimized radius of curvature at corners comprises the steps of: pressing a metal plate(P) in a pres mold(10) and plasticizing to bend a corner of the pressed product into an arc shape, cutting one side of the plasticized pressed product with a grinding member, and plating, painting, coating, or depositing the surface of the pressed product. In the grinding step, the height of a lower fixing jig or abrasive cloth jig is adjusted so that the pressed product comes into contact with the grinding member and the lower fixing jig and the abrasive cloth jig are rotated in opposite directions with the grinding member in contact with one side of the pressed product so that the arc of the pressed product is reduced or removed by friction against the grinding member.
