CUTTING TOOL WITH POLYCRYSTALLINE DIAMOND SINTER BODY
To provide a cutting tool having a polycrystalline diamond sinter body, that is suitable for use in cutting materials to be cut, excluding: fiber-reinforced plastic materials, such as carbon fiber reinforced plastic materials; laminate materials in which the fiber reinforced plastic material and a metal material, such as a titanium alloy material or an aluminum alloy, are superimposed on one another; composite materials consisting of carbon materials; and ferrous materials, such as ceramic materials.SOLUTION: On at least the tip of a tool body 1 to be rotated about an axis O, a cutting edge 7 is formed that extends from an inner peripheral side to an outer peripheral side of the tool body 1. The cutting edge 7 is formed on a polycrystalline diamond sinter body 8 disposed at the tip of the tool body 1. The polycrystalline diamond sinter body 8 has different compositions in an inner peripheral layer 8A of the inner peripheral side and in an outer peripheral layer 8B of the outer peripheral side of the tool body 1.SELECTED DRAWING: Figure 2
【課題】炭素繊維強化プラスチック材等の繊維強化プラスチック材や該繊維強化プラスチック材とチタン合金材やアルミニウム合金等の金属材とを重ね合わせた積層材、あるいは炭素材同士のコンポジット材、もしくはセラミックス材等の鉄系材料以外の被削材の切削に用いて好適な多結晶ダイヤモンド焼結体付き切削工具を提供する。【解決手段】軸線Ｏ回りに回転される工具本体１の少なくとも先端に、工具本体１の内周側から外周側に延びる切刃７が形成され、この切刃７は、工具本体１の先端部に配設された多結晶ダイヤモンド焼結体８上に形成されていて、多結晶ダイヤモンド焼結体８は、工具本体１の内周側の内周層８Ａと外周側の外周層８Ｂとで組成が異なる。【選択図】図２
