| 摘要 |
The present invention relates to a cutting insert for shoulder milling cutting. The insert comprises rectangular end surfaces, first side surfaces and second side surfaces connecting the end surfaces and facing each other. First cutting edges and second cutting edges in the first side surface are diagonally symmetrical with respect to a first imaginary median plane, which transverses the middles of both the first side surfaces facing each other. The first cutting edges and the second cutting edges in the second side surface are diagonally symmetrical with respect to a second imaginary median plane, which transverses the middles of both the second side surfaces facing each other. The second cutting edge is offset toward the first median plane from the first cutting edge. The first cutting edge is offset toward the second median plane from the second cutting edge. |
