The present invention relates to a boom manufacturing apparatus, comprising: a base including a lower jig, a first driving part, and a second driving part on both sides in a longitudinal direction; a vertical member including a pair of a first vertical column and a second vertical column in the form of facing each other in the upper part of the base, and having a first cylinder horizontally moving in one among the first and second vertical columns; a horizontal member formed in the horizontal column which rotates based on one among the first and second vertical columns for connecting the upper parts of the first vertical column and the second vertical column while being located in the upper part of the vertical member, including an upper jig corresponding to the lower jig formed in the base, and having a second cylinder vertically moving; a support part wherein the vertical member and the horizontal member are formed to be arranged at a distance away in the longitudinal direction of the base; and a fixture mold whose both sides are connected to the first and second driving parts formed on the base, slide in the longitudinal direction of the base, and are formed in the form of a circle or a polygon. The present invention supports the inside of a boom while smoothly moving a fixture mold through first and second driving parts formed on a base, improves operation efficiency while precisely manufacturing a boom without an error, and more precisely shaping a boom through a fixture mold which moves by first and second driving parts.
