PURPOSE: To provide an automatic self-aligning type round bar guiding apparatus for supplying the workpiece to the bite in such a way that the central point of a round bar workpiece supplied to a bite through an infeed roller is accurately adjusted to the rotary central point of the bite and preventing vibration of the workpiece during peeling. CONSTITUTION: The automatic self-aligning type apparatus for guiding round bar comprises a front block(20) in a central part of which a through hole(21) passing through the front and back sides of the front block is formed, and at the backside of which a bearing supporting part(22) is installed so that a bearing(23) is supported by the bearing supporting part; a spiral gear(30) which is rotatably connected to the bearing installed on the bearing supporting part of the front block, on the outer circumferential surface of which a first gear part is formed, and on the backside of which a second gear part is formed; a plurality of guiding means(10) arranged in a circular shape around the central point of the spiral gear, the plurality of guiding means comprising a third gear part engaged with the second gear part of the spiral gear so that the plurality of guiding means are moved to the central point of the spiral gear or to the opposite side by rotation of the spiral gear, and a roller installed at an end part of the third gear part; a backside block(40) which is formed in such a plate shape that the backside block is assembled with the front block, on which a through hole(21) passing through the front and back sides of the backside block is formed, and in which a guiding space assembled with the front block is formed to move the guiding means; and a driving part comprising a worm(51) engaged with the first gear part of the spiral gear, and a handle and a motor connected to both ends of the worm to rotate the worm.
