Abstract

PURPOSE:To make a lip edge of arc-shape capable of cutting and fabricating spherical surfaces, by screw tightening a tip of disc-shape to the tip seat which is constructed by a diagonal mounting at one end of the main unit shaped into a pattern of column. CONSTITUTION:A throw-away tip 3 is installed to the tip seat 2 of a main unit 1 by a mounting screw 4. At this time, the side of its thickness direction constitutes a rake face 8, and the face to present a circular shape constitutes a relief face 9. An edge 10, constituted by the rake face 8 and the relief face 9, makes a circular arc curve with respect to the rotational direction, preforming an operation of three- dimensional cutting, thus easily capable of cutting and fabricating the spherical surfaces.
