Zusammenfassung:PROBLEM TO BE SOLVED: To provide a pipe machining device capable of manufacturing a shaped pipe such as a bellows pipe having wave-like bellows without using a die.SOLUTION: The pipe machining device 10 includes: two chucks 11, 12 for holding a pipe P at first and second holding positions H1, H2, respectively, so as to sandwich a heating section S of the pipe P which is formed of a heating coil 14, and a mandrel 13 abutting to the pipe P between the holding positions H1 and H2 to support the pipe P. In the device, transfer devices 15, 16 are used to shorten a distance between the holding positions H1, H2 to impart a compressing force in the axial direction of the pipe P between the holding positions H1, H2.
