Abstract
A polishing machine for polishing a periphery of a sheet of the present invention comprises a grinding shaft tilting mechanism () capable of changing a tilting angle of a rotary shaft of a grinding stone () with respect to a rotary shaft of the sheet () and also capable of changing its tilting direction. Accordingly, in a recess portion or a protrusion portion in the periphery, when the tilting direction is changed while the tilting angle is being maintained, chamfering (polishing) can be executed with high accuracy in the same manner as that of the outer circumferential portion of the sheet.
