Abstract: A quill supporting member supporting a quill may include a movable body, e.g. Z-axis movable body that moves in a Z-axis direction of an XYZ orthogonal coordinate system representing a shaft core of the quill as an Z-axis. A tool holder supporting member supporting a tool holder for holding a tool may include the other movable bodies, e.g. an X-axis movable body that moves in an X-axis direction and a Y-axis movable body that moves in a Y-axis direction. Therefore, the quill is shortened in the Z-axis direction, and a contact area is reduced between a guide path of the quill and a wire rod.

Abstract: Providing a coil spring manufacturing machine capable of adjusting the shape of a manufactured spring with fixing a wire feeding unit, followed by moving a shaping tool mounting member, attached to one or a plurality of movable members, in the front-rear, left-right, and/or up-down direction of the wire feeding direction. The shaping tool mounting member may be moved in all the three directions. Each movable member is provided with a drive source for driving the movable member.

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.
