[0007] An indexable carbide grooving insert for cutting-off and grooving operations, comprising a blade body. A machining edge portion is provided on the blade body, and the machining edge portion includes a double-sided high-low type radial main cutting edge that is lower in the middle and higher on both sides. Axial main cutting edges are provided on both sides of the double-sided high-low type radial main cutting edge;
[0008] The axial main cutting edge is in the shape of an outwardly protruding body that slopes upward, and the edge body of the axial main cutting edge is arranged in a high-low slope shape, forming an axially outwardly convex high-low axial edge body structure.
[0009] Further, a machining chip convergence groove is provided in the middle of the blade body corresponding to the double-sided high-low type radial main cutting edge.
[0010] Further, the machining chip convergence groove is connected to a machining chip outward discharge rising slope.
[0011] Further, a machining chip discharge ramp is also provided on the blade body corresponding to the machining chip outward discharge rising slope, forming a smooth chip evacuation structure in combination.
[0012] Further, the blade body is in the shape of a long rectangular bar, and machining edge portions are provided at both ends.
[0013] Further, the blade body is clamped to the machining equipment, and one of the machining edge portions is directly aligned with the workpiece material, or rotated by an appropriate angle to align with the workpiece material, forming an indexable grooving insert structure.
[0014] Compared with the prior art, the utility model has smooth chip removal, effectively reduces the load of the machine tool, maintains a good tip temperature, effectively improves the impact resistance, and effectively improves the processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
