The disk edge polishing machine is capable of polishing an inner edge of a center hole of a disk and an outer edge thereof. In the disk edge polishing machine, a sucking member has a cylindrical end section. The sucking member sucks the disk by the cylindrical end section and exposes the inner edge and the outer edge of the disk. The sucking member spins together with the disk. An outer polishing member polishes the outer edge of the disk. An inner polishing member is inserted into the center hole and simultaneously polishes the inner edge of the disk. A first driving mechanism relatively moves the outer polishing member and the sucking member close to and away from the outer edge of the disk along a predetermined course. A second driving mechanism relatively moves the inner polishing member and the sucking member close to and away from the inner edge of the disk along another predetermined course extended from the predetermined course.
