PROBLEM TO BE SOLVED: To provide a polishing method and a polishing machine capable of polishing the polishing surface of a work having different curvature radii in a longitudinal direction and in a short side direction crossing the longitudinal direction at right angles and having a concave surface in the short side direction without waviness and not requiring an auxiliary tool such as a polishing protector in polishing. SOLUTION: This invention relates to the method for polishing the polishing surface having different curvature radii in the longitudinal direction and the short side direction crossing the longitudinal direction at right angles and having the concave surface in the short side direction. A column-shaped polishing wheel having a larger diameter than the total width of the polishing surface in the short side direction is employed. The column-shaped polishing wheel is rotated around an axial line while the axial line is set toward the longitudinal direction. The column-shaped polishing wheel and the polishing surface are relatively moved in the longitudinal direction to simultaneously polish the whole width in the short side direction of the polishing surface.
