[0016] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0017] Please refer to Figure 1 and Figure 2A milling cutter includes a cylindrical cutter body 10. The cylindrical cutter body 10 has parallel first and second cutter grooves 30 formed on its peripheral wall. Both the first and second cutter grooves 20 extend from one end of the cylindrical cutter body 10 to the other. A plurality of first protrusions 21 are spaced apart along the length of one side of the first cutter groove 20. These protrusions 21 protrude sequentially toward the other side of the first cutter groove 20, and each of the end faces of the protrusions 21 is provided with a first blade 22. A plurality of second protrusions 31 are spaced apart along the length of one side of the second cutter groove 30. These second protrusions 31 and the first protrusions 21 are staggered along the length of the cylindrical cutter body 10. The second protrusions 31 protrude sequentially toward the other side of the second cutter groove 30, and each of the end faces of the second protrusions 31 is provided with a second blade 32.

[0018] In the above scheme, several first blades 22 are installed on corresponding first bosses 21, and the several first blades 22 are arranged in a staggered manner. As the cylindrical cutter body 10 rotates, the product is cut in segments, making cutting easier, improving cutting quality, and extending blade life. In addition, several second blades 32 are installed on corresponding second bosses 31, also arranged in a staggered manner, and adopt a segmented cutting method. They are staggered with the several first blades 22 along the length direction of the cylindrical cutter body 10 to ensure that the blades can cut the entire surface of the product.

[0019] Specifically, there are two first cutting grooves 20 and two second cutting grooves 30. The two first cutting grooves 20 are symmetrically arranged with respect to the axis of the cylindrical cutter body 10, and the two second cutting grooves 30 are also symmetrically arranged with respect to the axis of the cylindrical cutter body 10. A first cutting insert 22 is installed in each of the two first cutting grooves 20, and a second cutting insert 32 is installed in each of the two second cutting grooves 30. During cutting, all cutting inserts work together, improving cutting efficiency and cutting quality.

[0020] Furthermore, a first chip removal groove 23 is formed on the side wall of the first tool groove 20 corresponding to the position of the first boss 21, and a second chip removal groove 33 is formed on the side wall of the second tool groove 30 corresponding to the position of the second boss 31. The chip removal grooves are positioned to correspond to the positions of the blades on the bosses, allowing for faster chip removal, easier cutting, and a smoother cutting surface, thereby increasing the service life of the blades.

A notch 41 is formed on the hemispherical cutter body 40 at one end corresponding to the first cutting groove 20. A third cutting blade 42 is provided on one side of the first cutting blade 22 corresponding to the notch 41. The third cutting blade 42 is arc-shaped, with one end extending to one side of the first cutting blade 22 and the other end extending to the end of the hemispherical cutter body 40 away from the cylindrical sphere. The third cutting blade 42 on the hemispherical cutter body 40 is connected to the first cutting blade 22 on the cylindrical cutter body 10, which can meet different cutting requirements of the product and increase its application range.

[0023] Furthermore, a third chip removal groove 43 is provided at the position of the notch 41 corresponding to the third cutting tool 42. The third chip removal groove 43 can accelerate the removal of waste chips generated by the cutting of the third cutting tool 42, making cutting easier and increasing the service life of the third cutting tool 42.
