PROBLEM TO BE SOLVED: To provide a bar feeding device for a bar cutter which can accurately cut a material with a precise cutting length at low cost without labor and waste and can be accurately maintained. SOLUTION: The bar feeding device for the bar cutter includes a reach sensor 6 for outputting a reach signal at a cutting spot when an end of a bar 2 comes into contact therewith in a termination spot spaced by a cutting dimension from a cutting surface to a bar discharge side on a feed rail R and a feed amount sensor 7 for outputting a feed amount of the bar 2 passing a length measuring spot at the length measuring spot spaced by a fixed distance from the cutting surface in which the bar 2 is cut to a bar supply side on the feed rail R. The bar feeding device for the bar cutter includes a feed control means of a pinch roller 3 for outputting an acceleration command during a start of a feed operation, a constant velocity command during the reach of a maximum speed, a deceleration command before the completion of the feed operation and a stop command in accordance with the cutting dimension, the feed amount and the reach signal as deciding materials.
