CUTTING EDGE STRUCTURE FOR CUTTING TOOL, AND CUTTING TOOL WITH CUTTING EDGE STRUCTURE |
摘要 |
A cutting edge structure for a cutting tool including: a base member having first and second surfaces intersecting each other; and a cutting edge member supported by the base member and having higher hardness than the base member. The cutting edge member includes a coating formed by generating electric discharge between the second surface and a discharge electrode and by depositing a constituent material of the discharge electrode or a reacted substance of the constituent material on the second surface, the discharge electrode being formed by molding powder of metal, powder of a metal compound, powder of a ceramic, or powder of a mixture thereof. An edge of the coating projects from a cross ridge line between the first and second surfaces toward a distal end side of a cutting edge. The cutting edge angle is 10° to 20° inclusive. |
