Abstract
PURPOSE: To notch spiral grooves easily by using the motion of a knife edge which is let to be touched in a predetermined angle with ball substances such as mild metals, plastics, etc.
CONSTITUTION: Ball substances 10, 11 formed by mild metals, plastics, etc., are connected with the 1st axle 12 the axial center of which accords with the axle going through the conters of the ball substances 10, 11. Then if the axle 12 is made to rotate in the arrow I direction and rotate the substances 10 and 11, since a knife edge 17 is in slant contact with the equatorial surface of the substance 10 the edge 17 is let to move in the arrow I direction and as a result moves to draw a logarithic spiral locus 21 on the surface of the ball substance 10. Therefore a tool 19 synchronizes with the motion of the edge 17, moves to draw a logarithic locus 22 on the surface of the substance 11 and notches spiral grooves on the substance 11.
