ッドのねじ送り機構。In a head screw feeding mechanism configured to feed a head guided and slid by a guide shaft by a feed screw rotationally driven by a motor, the lead angle of the thread groove of the feed screw is the same as S. A roller tilted at an angle is rotatably supported on the head, the roller is engaged with a thread groove of the feed screw, and the roller is rotated by the rotation of the feed screw and transferred in the axial direction of the feed screw. A screw feed mechanism for a head, characterized in that the head is screw fed by using a screw.
