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.
