切刃部のすくい面に前記切刃部の母材より耐摩耗性の高い材料の被覆が施され、前記切刃部の逃げ面の全部又は前記切刃部の切刃先端に連続する一部において前記母材が露出してなる切削工具。 The rake face of the cutting edge part is coated with a material having higher wear resistance than the base material of the cutting edge part, and the flank of the cutting edge part or a part continuous to the cutting edge tip of the cutting edge part A cutting tool in which the base material is exposed. 超硬合金を母材として切刃部が形成され、
前記切刃部のすくい面にダイヤモンド被覆が施され、前記切刃部の逃げ面の全部又は前記切刃部の切刃先端に連続する一部において前記母材が露出してなる切削工具。 The cutting edge is formed using cemented carbide as the base material.
A cutting tool in which the rake face of the cutting edge portion is coated with diamond, and the base material is exposed at all of the flank face of the cutting edge portion or a part continuous with the cutting edge tip of the cutting edge portion. 切刃先端から軸方向後方に連続する稜線に沿って逃げ面側に延在し前記逃げ面に連続するマージンのうち、少なくとも前記逃げ面に連続する一部においては母材が露出していることを特徴とする請求項１又は請求項２に記載の切削工具。 The base material is exposed in at least a part of the margin that extends to the flank side and extends to the flank side along a ridge line that extends rearward in the axial direction from the tip of the cutting edge and continues to the flank face. The cutting tool according to claim 1 or 2, wherein 前記すくい面を含めた前記切刃部の表面に前記被覆を施した後、前記逃げ面上の被覆を除去して前記母材を露出させる請求項１又は請求項２に記載の切削工具の製造方法。 The manufacturing of the cutting tool according to claim 1 or 2, wherein after the coating is applied to the surface of the cutting edge portion including the rake face, the coating on the flank is removed to expose the base material. Method. 前記すくい面を含めた前記切刃部及び前記一部の表面に前記被覆を施した後、前記逃げ面上及び前記一部上の被覆を除去して前記母材を露出させる請求項３に記載の切削工具の製造方法。 The said base material is exposed by removing the coating on the flank and the part after the coating is applied to the cutting edge part including the rake face and the part of the surface. Method of manufacturing cutting tools. 切刃部のすくい面に前記切刃部の母材より耐摩耗性の高い材料の被覆が施され、The rake face of the cutting edge is coated with a material having higher wear resistance than the base material of the cutting edge,
被削材の切削中に、前記被覆の前記切刃部の切刃先端の縁部が前記被削材との摩擦による摩耗により脱落するとともに前記切刃部の逃げ面の母材が前記被削材との摩擦による摩耗により後退することを特徴とする切削工具。During cutting of the work material, the edge of the cutting edge of the cutting edge portion of the coating falls off due to wear due to friction with the work material, and the base material of the flank of the cutting edge portion is cut by the work material. Cutting tool characterized by retreating due to wear due to friction with the material. 切刃部のすくい面に前記切刃部の母材より耐摩耗性の高い材料の被覆が施され、The rake face of the cutting edge is coated with a material having higher wear resistance than the base material of the cutting edge,
被削材の切削中に、前記被覆の前記切刃部の切刃先端の縁部が前記被削材との摩擦による摩耗により脱落するとともに前記切刃部の逃げ面の母材が前記被削材との摩擦による摩耗により後退することにより、前記切刃先端が鋭利に保持されることを特徴とする切削工具。During cutting of the work material, the edge of the cutting edge of the cutting edge portion of the coating falls off due to wear due to friction with the work material, and the base material of the flank of the cutting edge portion is cut by the work material. A cutting tool characterized in that the cutting edge tip is held sharply by retreating due to wear due to friction with the material.
