Referring to fig. 1, there is provided a schematic structural view of a milling cutter 1 according to an embodiment of the present application, the milling cutter 1 including a cutter body 11, a cutter insert 12, and a mounting hole 13, the mounting hole 13 being used for mounting the milling cutter 1 on a milling machine. The cutter body 11 may include a plurality of cutter edges 111, at least one mounting groove 112 is provided on each cutter edge 111 along a length direction of the cutter edges 111, and the blade 12 may be mounted in the mounting groove 112. The blade body 11 may be in an integrally formed structure, and the blade 12 may be fixedly mounted in the mounting groove 112 by screws, bolts or other detachable mounting manners, so that the blade can be replaced during subsequent maintenance.
As can be seen from fig. 1, the positions of the mounting grooves 112 on any two opposing cutter edges 111 are the same, and the positions of the mounting grooves 112 on any two adjacent cutter edges 111 are different.
It should be noted that, the two opposing cutter edges 111 refer to two cutter edges 111 located on the cross-sectional diameter of the cutter body 11, and further, it is understood that the number of cutter edges 111 is even, and the positions of the mounting grooves 112 on the two cutter edges 111 are the same, so that the positions of the blades 12 mounted on the two cutter edges 111 are also the same, and the cutting positions of the blades 12 on the two cutter edges 111 are also the same when the workpiece is machined. That is, any one of the grooves to be machined may have two blades 12 cut in turn, so that the machining time can be shortened and the machining efficiency can be improved.
The positions of the mounting grooves 112 on any two adjacent cutter edges 111 are different, so that when the cutter body 11 rotates for one circle, a plurality of parallel grooves can be machined, the machining time can be further shortened, the machining process is saved, the machining efficiency is improved, and the production cost is saved.
In the embodiment of the present application, as shown in fig. 2, a schematic cross-sectional structure of a milling cutter body provided in the embodiment of the present application is shown, and two cutter edges 111 located on a cross-sectional diameter L-L' of the cutter body 11 may be regarded as a set of cutter edges 111, and the bottom thickness of each set of cutter edges 111 is the same. Therefore, the cutting force of each time of the single blade edge 111 can be reduced, and the rigidity requirement on the cutter handle is reduced, so that the service lives of the milling head and the cutter handle can be prolonged.
As can be seen in fig. 1, flutes 113 are formed between any two adjacent cutter edges 111 for discharging chips generated by the milling process.
Further, the thicknesses of the bottoms of the adjacent two junk slots 113 are different, and in one embodiment, the difference between the thicknesses of the bottoms of the adjacent two junk slots 113 is 1mm-2mm. Specifically, the difference in the thickness of the bottoms of the two chip removal grooves 113 is equal to the distance between the two adjacent mounting grooves 112 on the same cutter edge 111, so that when different cutter edges 111 process the same workpiece, the cutter is not required to be repeatedly aligned, namely, the two adjacent cutter edges 111 can serve as the cutter edges 111 which are further complemented with each other, when the workpiece structure needs more grooves, the limitation of the lengths of the cutter edges 111 can be avoided, and therefore, only the cutter handle is required to be rotated, and other cutter edges 111 can process more grooves.
In the embodiment of the present application, the number of the cutter edges 111 is not limited, and may be specifically determined according to the number of grooves to be processed, the number of the mounting grooves 112 on each cutter edge 111, and the actual needs.

Further, the number of mounting grooves 112 on each blade edge 111 may be determined by the following formula:
wherein N is the number of mounting grooves on each cutter edge, S is the number of grooves to be processed, and N is the number of cutter edges on the cutter body.
In the embodiment of the present application, the position of the mounting groove 112 on each knife edge 111 is determined according to the position of the groove to be processed on the workpiece to be processed, specifically, the position of the mounting groove 112 corresponds to the position of the groove to be processed, so as to ensure that the corresponding groove can be processed according to the production requirement.

It should be noted that this embodiment does not provide a schematic view, but the structure of the blade edge can be easily deduced from the above description.
Correspondingly, the positions of the three mounting grooves used for machining the 3 grooves with the numbers of 1, 2 and 3 on the first cutter edge 1111 and the fourth cutter edge 1114 correspond to the positions of the 3 grooves with the numbers of 1, 2 and 3, so that the production of the cutter blade after being mounted can be ensured, and the 3 grooves need to be machined.
Similarly, the positions of the three mounting grooves for machining 3 grooves of numbers 4, 5, and 6 on the second blade edge 1112 and the fifth blade edge 1115 correspond to the positions of 3 grooves of numbers 4, 5, and 6, and the positions of the three mounting grooves for machining 3 grooves of numbers 7, 8, and 9 on the third blade edge 1113 and the sixth blade edge 1116 correspond to the positions of 3 grooves of numbers 7, 8, and 9.

Then, the spacing between the first mounting groove 1121 and the fourth mounting groove 1124 should correspond to the spacing between the groove numbered 1 and the groove numbered 2.
Further, the pitch of the two mounting grooves 112 located on the adjacent two knife edges 111 and located adjacently may be set to coincide with the pitch of the grooves to be processed for each mounting groove, for example, the pitch between the two grooves is 1mm to 2mm, and then the pitch between the first mounting groove 1121 and the fourth mounting groove 1124 is also 1mm to 2mm. However, in actual implementation, the distance between two adjacent mounting grooves 112 on the same blade edge 111 may be set to any reasonable distance according to the structural requirement of the workpiece.
