Abstract:
When a tip of a blade cascade is ground with a grindstone, a jig is inserted between blade cascades of a blisk and a jig is inserted between blade cascades. A blade locking section of the jig locks with a side section in the width direction of a corresponding rotor blade via a damping member made from rubber or the like. A disk locking section of the jig locks with a disk of the blade cascade which the blade locking section locks with.
