Abstract
A spring manufacturing apparatus includes a supporting body which moves in X, Y, and Z-axes directions of a XYZ orthogonal coordinate system representing a moving direction of a wire rod fed from a wire rod feeding unit as a Z-axis. The supporting body is formed with an opening in which the quill is arranged. The supporting body further includes a tool holder for holding a processing tool for processing the wire rod to a spring. The supporting body arranged at the vicinity of the quill is moved to accurately adjust the relative position of the quill and the processing tool, thereby manufacturing a desired spring.
