摘要

To provide a lathing method for a hollow cylindrical workpiece, by which the occurrence of chattering vibration and a deformation is suppressed for a long period of time and a highly accurate hollow cylindrical workpiece can be produced.SOLUTION: A lathing method for a hollow cylindrical workpiece includes: an insertion step of inserting a core having a shaft and a plurality of thin plate-like elastic bodies, through which the shaft is penetrated via a spacer, into the hollow cylindrical workpiece; and a lathe turning step of lathing the surface of the hollow cylindrical workpiece, in which the thin plate-like elastic bodies have the maximum outer diameter, which is smaller than the inner diameter of the hollow cylindrical workpiece, and come in contact with the inner surface of the hollow cylindrical workpiece at the time of lathing.SELECTED DRAWING: None
