摘要： A cutting insert, and more particularly, an improved double-sided cutting insert is provided, which provides improved machinability obtained due to increased rake angle, without compromising coupling state. The double-sided cutting insert includes a top surface, a bottom surface, a plurality of lateral relief surfaces connecting the top and bottom surfaces, and a cutting edge formed by the top and bottom surfaces and the plurality of lateral relief surfaces, in which one or more lateral relief surfaces of the plurality of lateral relief surfaces are formed into three stages in sequence which are a first positive surface, a negative surface and a second positive surface in a direction from the top surface to the bottom surface.

摘要： A cutting insert is disclosed, where the shape of a cutting edge is improved so that the minimum cutting load is applied during a cutting process to obtain the same surface roughness although the cutting insert is fed at high speed and to thus obtain high efficiency and high productivity. The diamond-shaped cutting insert includes an upper part and a lower part, a top surface and a bottom surface that are lower than the upper part and higher than the lower part, respectively, side parts for connecting the top surface to the bottom surface, corner parts for smoothly connecting the side parts to each other, a cutting edge formed by crossing the top surface, the bottom surface, the side parts, and the corner parts, and a chip breaker formed from the cutting edge to between the top surface and the bottom surface.
