To provide a manufacturing method for a metal round rod material efficiently manufacturing it by in-line processing, reducing facility investment by space-saved production facility, and manufacturing the surface uniform quality at low cost.

This manufacturing method for the metal round rod material is characterized in having a first process turning-machining the hot rolled round rod material and a second process polishing the metal round rod material turning machined in the first process by a polishing device capable of polishing it on the central axis of the turning device without rotating.
