FIELD: process engineering.
SUBSTANCE: invention relates to metal forming, particularly, to making metal sleeves. Billet ends are clamped. Billet inner surface is machined by rolling with smoothing and deforming rollers. The latter have section with larger diameter. Rolling by said rollers is performed by reciprocating them toward billet opening axis. Note here that billet is arranged in container to lock billet outer lateral surface.
EFFECT: submicron and nanocrystalline hardened structure on billet surface.
