Beschreibung
Zusammenfassung:	A rotary machining device (1) provided with a rotation device (2) for supporting a workpiece on which helical teeth are formed and causing the workpiece to rotate, a machining device (3) for using grinding teeth (71) of a rotary grindstone (7) to grind the helical teeth of the workpiece caused to rotate by the rotation device (2), and a transportation device (4) for loading and unloading the workpiece (8) to and from the rotation device (2). The transportation device (4) has a plurality of grippers (51) for holding the workpiece and dressers (52) for molding the grinding teeth (71). The transportation device (4) turns about a turn center axis (401), causes the grippers (51) to sequentially move nearer the rotation device (2), and causes the dressers (52) to sequentially move nearer the machining device (3). The dress teeth of the dressers (52) have tooth surfaces that are differently shaped from each other.
