PURPOSE: Four-direction forging system and method of an axle are provided to reduce material costs compared to product processing like a turning operation since the diameter of a target decreases and the length of the target increases by a forging operation. CONSTITUTION: A four-direction forging system of an axle comprises a left clamp, a right clamp, a loading unit, a forging unit, and an unloading unit. The forging unit comprises a die, which makes selective contact with the outer surface of a target(M). The die comprises a lateral protrusion, a lateral slope, a central surface, and a plurality of slopes. The lateral slope is formed on the left and right surfaces of the lateral protrusion at an angle. The central surface is formed on the central part. The slopes are symmetrically formed on the front and rear of the central surface. The slopes are formed as concave surfaces.
