specific Embodiment approach 1
[0021] Specific implementation mode one: combine Figure 1-Figure 3 Description, a heavy-duty cutting indexable turning and milling composite insert, the forward projection of the rake face of the insert is a square, the insert has four straight cutting edges 1, and the junction of adjacent straight cutting edges 1 has an arc cutting edge 3; The contour guarantees that the blade is a symmetrical structure, and the cutting depth of the cutting edge is the same, which improves the processing efficiency and blade utilization rate during turning or milling.
specific Embodiment approach 2
[0022] Specific implementation mode two: combination figure 1 , figure 2 Explain that a heavy-duty cutting indexable turn-milling compound insert described in this embodiment has a rake angle of 8 ° left and right, rear angle is 7 ° left and right, blade inclination angle is 0 ° ; The undisclosed technical features in this embodiment are the same as those in Embodiment 1.
specific Embodiment approach 3
[0023] Specific implementation mode three: combination figure 1 , figure 2 Explain that a kind of heavy-duty cutting indexable turning-milling composite insert described in this embodiment is designed with a negative chamfer 2 with a width of 0.2 mm, which can increase the impact resistance of the insert and improve the wear resistance of the insert; The undisclosed technical features in the embodiment are the same as those in the first embodiment.
