Cutting Insert and Cutting Tool Including the Same

摘要

An indexable cutting insert is suitable for vertical and oblique machining. The cutting insert has top and bottom surfaces, first to fourth side surfaces extending between the top and bottom surfaces, and a screw hole passing through the top and bottom surfaces. The top surface has a mounting surface of a flat surface. The top and bottom surfaces are rotationally symmetric with each other. A cutting edge is formed at a junction between the top surface and the adjacent first and second side surfaces. A non-cutting edge is formed at a junction between the top surface and the adjacent third and fourth side surfaces. The first and second side surfaces form an acute angle with a plane extending from the mounting surface of the top surface. The third and fourth side surfaces form an obtuse angle with the plane extending from the mounting surface of the top surface.

1. A cutting insert, comprising:
a top surface; a bottom surface; first to fourth side surfaces extending between the top surface and the bottom surface; and a screw hole passing through the top surface and the bottom surface, wherein the top surface includes a mounting surface comprising a flat surface, and the top surface and the bottom surface are rotationally symmetric with each other, wherein a cutting edge is formed at a junction between the top surface and the first and second side surfaces, the first and second side surfaces being adjacent to each other, wherein a non-cutting edge is formed at a junction between the top surface and the third and fourth side surfaces, the third and fourth side surfaces being adjacent to each other, and wherein the first and second side surfaces form an acute angle with a plane extending from the mounting surface of the top surface, and the third and fourth side surfaces form an obtuse angle with the plane extending from the mounting surface of the top surface.
