ABSTRACT:
There is provided a bar material supply device of a simple configuration suited to machining of a bar material without increasing machining cost even when a short bar material such as an end material is machined. The bar material supply device includes a stocker12for supplying a bar material w on an axis C of a spindle230, a base10attached to a head stock220, a push rod15disposed in the base10to move back and forth on the axis C and to push the bar material w fed from the stocker12, a push rod guide11disposed in the base10to guide the back-and-forth movement of the push rod15, a plurality of rollers arranged on both sides of the axis C of the base10to hold the push rod15on the axis C therebetween, one of the plurality of rollers being constituted as a driving roller135which is rotated by a driving body disposed in the base, and at least one of the other rollers excluding the driving roller135being constituted as a driven roller132which is rotated without any slippage with the push rod15, and rotation detection means133for detecting the rotation of the driven roller132.
