Provided is a rod feeding machine that is capable of preventing run out of a rod, and easily matching the height of the axis of the rod, which is received inside a guide rail, with the height of the rotation axis of a main shaft. This rod feeding machine (20) comprises a guide rail (30), a feed arrow (50), and a centering device (100) that lifts a front end portion (Bb) of the rod (B) to a feed axis (21). The centering device (100) comprises a rotating shaft (102b) and a plate (102c) that rotate around a rotation axis (102a), and a bottom roller (106) and a top roller (108) that are rotatably attached to the plate (102c). The lower roller (106) is able to move between a bottom position (106a) positioned lower than the rod (B), and a top position (106b) where the rod (B) is lifted up to the feed axis (21). |
