To provide a worm form rolling processing method capable of preventing a material to be processed from elongation to the minimum and interference with the apparatus, in the warm form roll processing by the flat dies.
In the worm form rolling processing of a number of strips n by the flat dies, the lead angle of the flat dies and the material outside dia. (D2) of the guide cylindrical section are set up, so that the rolling circular dia. (D1) calculated by a flat die lead angle (θ) and an axial direction module (m) and the material outside dia. (D2) of the guide circular section abutting with the pressing surface of the pressing board, situated in the axial end side of the worm roll processing region of the material to be processed, are substantially equal to each other and satisfy the relationship of the following formula: D2D1=n×m÷tanθ.
