Claims

[Scope of Claim for Utility Model Registration] (1) A throw-away type face milling cutter in which a tip mounting seat is provided on the outer periphery of the tip of a cylindrical tool body, and a throw-away tip is attached to each chip mounting seat. away chips,
It has an octagonal plate shape, and has cutting edges that intersect at obtuse angles formed on each ridgeline on at least one of its upper and lower surfaces, and a plurality of adjacent cutting edges are arranged as main cutting edges. A throw-away type front milling cutter featuring: (2) The throw-away tip is formed so that the angle between adjacent cutting edges is 45°, and the cutting edge located on the outer circumference side is -5° with respect to the plane containing the rotation axis of the tool body. °~+5°
The side surface continuous with the proximal cutting blade is in contact with the wall of the tip mounting seat, and this wall is at least connected to the outer peripheral side of the proximal cutting blade. A throw-away type face milling cutter according to claim 1, wherein a portion on the outer peripheral side from the edge is formed to be open toward the base end side of the tool body. (3) The above indexable tip is a positive tip in which the side surface and the top surface intersect at an acute angle, and the axial rake angle of the main cutting edge is 0 to 25 degrees, and the relief angle of the main cutting edge is 5 to 30 degrees. A throw-away type face milling cutter according to claim 1 or 2 of the utility model registration claim.
