Title:
切削インサートおよび刃先交換式切削工具
Document Type and Number:
Japanese Patent JP7464877
Kind Code:
B2
Abstract:
A convex arc-shaped corner edge (3) centered on a corner edge center line is formed at a corner portion of a polygonal surface (2) of a polygonal plate-shaped insert main body (1). A land portion (7) that gradually protrudes in an insert center line direction from the corner edge (3) toward an inner side of the polygonal surface (2) is formed on the polygonal surface (2), and a rake face portion (8) that gradually recedes in the insert center line direction toward the inner side of the polygonal surface (2) is formed closer to the inner side of the polygonal surface (2) than the land portion (7). Within 40° around the corner edge center line from a corner edge first end portion toward a corner edge second end portion along the corner edge (3), an inclination angle Θ1 of the land portion (7) with respect to a reference plane (P) perpendicular to an insert center line is an inclination angle Θ2 or more of the rake face portion (8) with respect to the reference plane (P), in a cross-section along the corner edge center line.
