[0024] Reference is made below Figures 1-7 A indexable cutting tool 1000 according to an embodiment of the present application is described below, the indexable cutting tool 1000 comprises a blade body 100 having a cutting edge 20, the indexable cutting tool 1000 further comprises a tool body 200, the blade body 100 is arranged on the tool body 200, the blade body 100 can be switched to use a new cutting edge 20 by indexing on the tool body 200.

[0025] like Figures 1-6 As shown, according to an embodiment of the present invention, the blade body 100 has a plurality of cutting surfaces 10, and a cutting edge 20 is provided at the intersection of at least two adjacent cutting surfaces 10. Each of the two cutting surfaces 10 is provided with a groove 101, and the groove 101 of each cutting surface 10 is adjacent to the cutting edge 20 and extends along the extension direction of the cutting edge 20.

[0026] The cutting surface 10 is the outer surface of the insert body 100. The cutting edge 20 is used to remove excess material from the workpiece. The groove 101 is a groove formed by an inward indentation of a part of the cutting surface 10. Since long chips can entangle the tool and the workpiece, making it impossible to continue processing and affecting processing efficiency, and long chips are also unsafe for the operator, a groove 101 is provided on one side of the cutting edge 20 to perform chip breaking function and form short chips, thereby controlling the chip flow and ensuring processing efficiency and safety. A groove 101 is provided on the other side of the cutting edge 20 to avoid processing interference.

[0027] By setting a groove 101 on each side of the cutting edge 20, when the cutting edge 20 participates in cutting and uses different cutting surfaces as the main rake face, the two grooves 101 can play different functions. One groove 101 plays the role of chip breaking, forming a chip breaking groove, while the other groove 101 plays the role of air clearance, forming an air clearance groove. This design makes the indexable cutting tool 1000 more adaptable to different machining methods (such as climb milling and conventional milling). No matter what working position the insert body is in, one groove 101 can always play the role of chip breaking, while the other groove 101 plays the role of air clearance. Thus, a stable and reliable chip breaking effect can be guaranteed under various working conditions, and cutting interference can be effectively avoided, improving the surface quality of the machined surface and operational safety.

[0028] For example, the first cutting edge 21 is provided at the intersection line of the first cutting face 11 and the second cutting face 12, the first cutting face 11 has a first recess 111, the second cutting face 12 has a second recess 121, the first recess 111 and the second recess 121 are respectively adjacent to the first cutting edge 21, the first recess 111 and the second recess 121 respectively extend along the extension direction of the first cutting edge 21, when the insert body 100 is in the first working position and the first cutting face 11 is used as the main rake face, the first recess 111 is a chip breaker, and the second recess 121 is a relief groove; when the insert body 100 is in the second working position after indexing and the second cutting face 12 is used as the main rake face, the second recess 121 is a chip breaker, and the first recess 111 is a relief groove, that is, when the insert body 100 is indexed and used for cutting on the other side of the same cutting edge 20, the recess 101 used for chip breaking can be used as a relief groove, and the recess 101 used for relief can be used as a chip breaker, so that the cutting edge 20 can be suitable for multiple cutting directions, the utilization rate of the cutting edge 20 is improved, and the application conditions of the insert body 100 are expanded.

[0030] As shown in Figure 1 and Figure 5 In some embodiments, the recesses 101 of the two adjacent cutting faces 10 are symmetrically arranged relative to the cutting edge 20 at the intersection line, so that the structures of the recesses 101 on the two sides of the cutting edge 20 are completely the same, when any cutting face 10 is used as the main rake face, the recesses 101 as chip breakers can achieve the same chip breaking effect, the chip breaking groove maintains the set cross-sectional shape and depth, can effectively control the curling and breaking of the chip, reduce the cutting resistance, and can promote the dissipation of cutting heat; the recesses 101 as relief grooves can effectively avoid cutting interference, thereby improving the machining surface quality and operation safety.

For example, the diameter of the positioning hole is D, and 3.5mm≤D≤10mm, so as to facilitate the installation of the insert body 100 on the tool body 200. Thus, each support protrusion 102 can be used as a positioning structure for connecting with the tool body 200, so that the support protrusion 102 can play a positioning and fixing role, and the insert body 100 can be installed on the tool body 200 by multiple support protrusions 102.
