PURPOSE: A beading machine is provided to minimize the fracture or deformation of a beaded part by employing a diameter expansion plate and precisely controlling a roller corresponding to the shape of the beaded part. CONSTITUTION: A beading machine comprises a body(10), a diameter expansion plate(110), a rotary support(100), and a beading roller unit(200). The diameter expansion plate is formed with a first shape corresponding to the shape of a beaded part along the outer peripheral surface, wherein the beaded part is formed in the body. The diameter expansion plate is expanded inside the body to be pressed onto the interior surface of the body. The rotary support rotates the body. The beading roller unit is formed with a second shape corresponding to the shape of the beaded part and rotates by contacting the rotating body.
