The chip breaker is disposed on the cutting surface, and the chip breaker has a V-shaped edge with an opening facing the main cutting edge. The chip breaker gradually recesses from the V-shaped edge towards the middle of the cutting surface to form a concave region.

[0023] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0024] See Figure 1The diagram shows a schematic of a slotting insert according to an embodiment of the present invention. The insert includes at least one cutting surface 100. The cutting surface 100 includes a main cutting edge 110, a first transverse moving cutting edge 120, a second transverse moving cutting edge 130, and a cutter 140. The main cutting edge 110 is disposed on one edge of the cutting surface 100, and its height gradually increases from the middle to both ends. The first transverse moving cutting edge 120 is disposed on the edge of the cutting surface 100 near one end of the main cutting edge 110, and the first transverse moving cutting edge 130... The cutting edge 120 gradually decreases in height from the end near the main cutting edge 110 to the end away from the main cutting edge 110; the second transverse moving cutting edge 130 is disposed on the opposite side of the first transverse moving cutting edge 120, and the first transverse moving cutting edge 120 gradually decreases in height from the end near the main cutting edge 110 to the end away from the main cutting edge 110; the chip cutter 140 is disposed on the cutting surface 100, the chip cutter 140 has a V-shaped edge 141 with an opening facing the main cutting edge 110, and the chip cutter 140 gradually recesses from the V-shaped edge 141 toward the middle of the cutting surface 100 to form a concave region 150.
[0025] Typically, cutting edges are designed as flat edges. The aforementioned grooving insert employs a high-low edge design. Based on the characteristics of the material being machined, in this embodiment, the main cutting edge 110 is set with a lower center and higher sides. The first transverse moving cutting edge 120 and the second transverse moving cutting edge 130 are both set with specific angles. This makes the chip removal direction more controllable, preventing chip removal from striking the tool's cutting edge and causing tool damage. It further improves the smoothness of chip removal, thereby reducing tool heat, increasing durability, and decreasing machine tool load. The durability of this product is 30% longer than that of other products on the market.
[0026] See Figure 4 and Figure 5 Preferably, in one embodiment, the height difference between the high point at the middle of the main cutting edge 110 and the low point at the end of the main cutting edge 110 is 0.2 mm; the tilt angle of the first transverse moving cutting edge 120 is 4°, and the height difference between the high point at one end of the first transverse moving cutting edge 120 and the low point at the other end is 0.2 mm; the tilt angle of the second transverse moving cutting edge 130 is 4°, and the height difference between the high point at one end of the second transverse moving cutting edge 130 and the low point at the other end is 0.2 mm.
[0027] In one embodiment, two cutting surfaces 100 are provided and are symmetrically arranged at both ends of the grooving blade 10.
[0028] See also Figure 2 and Figure 3In one embodiment, a central chip removal area 152 is provided at the centerline 151 of the concave region 150, and the central chip removal area 152 gradually expands from the side close to the main cutting edge 110 to the side away from the main cutting edge 110.
[0029] like Figure 2 and Figure 3 In one embodiment, the central chip removal region 152 includes a first region 1521, a second region 1522, a third region 1523, and a fourth region 1524 that gradually move away from the main cutting edge 110. The areas of the first region 1521, the second region 1522, the third region 1523, and the fourth region 1524 gradually increase, with the first region 1521, which is closer to the main cutting edge 110, having the smallest area. In this embodiment, the area of the first region 1521 is close to zero.
[0030] like Figure 2 As shown, in one embodiment, a fifth region 153 and a sixth region 154 that are symmetrically arranged on both sides of the first region 1521 are respectively provided; the fifth region 153 and the sixth region 154 gradually shrink from the side connected to the first region 1521 to the side away from the first region 1521.
[0031] like Figure 2 As shown, in one embodiment, a seventh region 155 and an eighth region 156 that are symmetrically arranged on both sides of the second region 1522 are respectively provided; the seventh region 155 and the eighth region 156 gradually expand from the side connected to the second region 1522 to the side away from the second region 1522 and extend to the V-shaped edge 141.
[0032] like Figure 2 As shown, in one embodiment, a ninth region 157 and a tenth region 158 that are symmetrically arranged on both sides of the third region 1523 are respectively provided; the ninth region 157 and the tenth region 158 both extend from the third region 1523 to the V-shaped edge 141.
[0033] like Figure 2 As shown, in one embodiment, eleventh regions 159 and twelfth regions 160 are respectively provided on both sides of the fourth region 1524. The eleventh region 159 and the twelfth region 160 gradually expand from the side connected to the fourth region 1524 to the side away from the fourth region 1524 and extend to the V-shaped edge 141.
[0034] The aforementioned grooving insert features a "Y"-shaped chip breaker design. Symmetrically distributed chip breaker areas are located on either side of the central chip breaker area 152, including symmetrical fifth and sixth areas 153 and 154, symmetrical seventh and eighth areas 156, symmetrical ninth and tenth areas 158, and symmetrical eleventh and twelfth areas 159 and 160. This design ensures smooth chip removal and allows for a suitable chip break angle tailored to the specific material being machined. The high and low edge design of the main cutting edge 110, the first transverse moving cutting edge 120, and the second transverse moving cutting edge 130 optimizes the length of the discharged chip, resulting in an ideal medium-length chip shape.
[0035] In one embodiment, an inclined connecting portion 170 is provided between the main cutting edge 110 and the opening of the chip cutter 140. This arrangement provides better support and facilitates the movement and discharge of metal chips.
