Claims (1)

[Scope of Claim for Utility Model Registration] A large number of retaining grooves with groove widths equal to or larger than the diameter of the round steel are arranged in parallel in the axial direction of the spiral roller at pitches corresponding to the pitches of the threads of the spiral roller as shown below. A round steel transfer member, which is connected to the round steel transfer member and moves the round steel transfer member up and down above and below the height position of the spiral roller, and reciprocates approximately in the axial direction of the spiral roller. A round steel supply device comprising a moving mechanism and a drive device connected to the moving mechanism and operating the moving mechanism; a rotating grindstone; and a face plate disposed above the rotating grindstone substantially parallel to its axis; A plurality of smooth rollers are rotatably disposed in front of the whetstone, and the axis of the shaft is inclined at a predetermined angle with respect to the rotary whetstone and the spiral roller; 1. A device for chamfering round steel, characterized in that it is configured in combination with a peripheral edge grinding device for the end face of round steel, which is composed of a plurality of spiral rollers each having a shaped thread formed on the outer periphery.
