Description

Technical Field

[0001] This utility model relates to the field of milling cutters, and in particular to a powerful chamfering milling cutter. Background Technology

[0002] Milling cutters are common components in machining, generally used in subtractive manufacturing to cut raw materials. In the machining of parts, after machining the main dimensions such as diameter, it is often necessary to chamfer the edges and corners. When using a milling cutter for chamfering on a machine tool, because the milling cutter uses its bottom surface for chamfering, and the contact area with the product is small, it bears high pressure. This can lead to chipping when machining materials with slightly higher hardness.

[0003] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a powerful chamfering end mill. This utility model is achieved through the following technical solution:

[0005] A high-power chamfering end mill includes a shank and a cutting edge. The cutting edge is fixedly disposed at one end of the shank. The cutting edge is provided with a plurality of cutting edges, and the plurality of cutting edges are disposed on the end face of the cutting edge. Each cutting edge includes a cutting face, a flank face, and a side bevel. The cutting face and the flank face are both inclined. The side bevel is disposed on one side of the cutting face. A plurality of helical cutting edges are provided on the cylindrical surface of the cutting edge. The position and number of the helical cutting edges correspond to the cutting edges. A chip removal groove is also provided between two adjacent helical cutting edges.

[0006] In the above technical solution: the shank is used for tool holder clamping; the cutting edge is used for cutting raw materials; the cutting face is used for cutting; the flank face is used to control the cutting shape; the side bevel is used to ensure that the thickness at the edge of the cutting face is not too thin, thereby avoiding chipping; the helical cutting edge is used to achieve side cutting; and the chip removal groove is used for chip removal.

[0007] A further feature of this invention is that the cutting edge further includes a chip discharge port, which is connected to the chip discharge groove.

[0008] In the above technical solution: the chip discharge port is used to guide the chips into the chip discharge groove.

[0009] A further feature of this invention is that the cutting surface is inclined.

[0010] In the above technical solution, the cutting edge is set at an angle to achieve cutting.

[0011] A further feature of this invention is that the back blade surface is inclined.

[0012] In the above technical solution, the back face is inclined so that the chip shape and chip removal direction can be controlled due to the uneven compression of the chips.

[0013] A further feature of this invention is that the side bevel intersects with both the cutting edge and the back face.

[0014] In the above technical solution: the beveled surface intersects with the cutting edge to strengthen the edge of the cutting edge; the flank face intersects with the flank face to strengthen the edge of the flank face.

[0015] This utility model discloses a high-power chamfering end mill, which, compared with the prior art:

[0016] This invention reduces the possibility of chipping during chamfering by setting a side bevel, which increases the thickness at the corner of the cutting edge.

[0017] This invention also makes it less likely for chips to get stuck by setting up a chip discharge port, thereby avoiding processing difficulties caused by chip accumulation. Attached Figure Description

[0021] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0022] like Figure 1 and 2As shown, this utility model proposes a powerful chamfering end mill, including a shank 10 and a cutting edge 20. The cutting edge 20 is fixedly disposed at one end of the shank 10. The cutting edge 20 is provided with a plurality of cutting edges 201, and the plurality of cutting edges 201 are disposed on the end face of the cutting edge 20. The cutting edge 201 includes a cutting face 201a, a flank face 201b, and a side bevel face 201c. The cutting face 201a and the flank face 201b are both inclined. The side bevel face 201c is disposed on one side of the cutting face 201a. The cylindrical surface of the cutting edge 20 is provided with a plurality of helical cutting edges 202. The position and number of the helical cutting edges 202 correspond to the cutting edges 201. A chip removal groove 203 is also provided between two adjacent helical cutting edges 202. Preferably, the cutting edge 201 can be divided into long edge and short edge according to its length, and the long edge and the short edge are arranged alternately; preferably, there are two long edges and two short edges; there are four spiral cutting edges 202, and the spiral angle of the spiral cutting edges 202 is 30 degrees; there are also four chip removal grooves 203.

[0023] like Figure 1 and 2 As shown, the present invention proposes a high-power chamfering end mill, wherein the cutting edge 201 further includes a chip removal port 201d, which is connected to the chip removal groove 203. The number of chip removal ports 201d is four.

[0024] like Figure 1 and 2 As shown, this utility model proposes a high-power chamfering end mill, wherein the cutting surface 201a is inclined. Preferably, the cutting surface 201a is unequally divided on the end face of the cutting edge 20.

[0025] like Figure 1 and 2 As shown, this utility model proposes a high-power chamfering end mill, wherein the flank face 201b is inclined. The inclination angle of the flank face 201b is greater than the inclination angle of the cutting edge 201a.

[0026] like Figure 1 and 2 As shown, this utility model proposes a high-power chamfering end mill, wherein the side bevel 201c intersects with both the cutting edge 201a and the flank face 201b. The inclination angle of the side bevel 201c is 45 degrees.

[0027] The working principle of this utility model is as follows:

[0028] When using a milling cutter for chamfering;

[0029] The cutting edge of the end mill's bottom surface comes into contact with the product to be machined;

[0030] When the cutting edge is subjected to force, it experiences a force perpendicular to the cutting edge.

[0031] Due to the presence of the lateral bevel, there is no thinner section at the edge of the cutting edge;

[0032] This allows the cutting edge to withstand the force, and the force received can be transmitted to the entire cutting edge through the back face;

[0033] This prevents the blade from chipping.

[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
