Beschreibung
Zusammenfassung:	The utility model provides a turning tool which is used for fixing a to-be-machined workpiece, the turning tool comprises a clamping body and a fastening device, the to-be-machined workpiece is arranged on the clamping body in a sleeving mode, the fastening device comprises an expansion piece, the expansion piece is arranged between the outer wall of the clamping body and the inner wall of the to-be-machined workpiece in the circumferential direction, and the expansion piece is arranged between the clamping body and the inner wall of the to-be-machined workpiece. And the supporting device is used for providing supporting force in the radial direction for the to-be-machined workpiece. The inner hole of the to-be-machined workpiece can be filled with the turning tool through the expansion piece, so that the outer circle of the to-be-machined workpiece is stressed uniformly in the turning process, the phenomena of burrs, tearing, deformation and the like of the outer circle of the to-be-machined workpiece in the
