Description

Technical Field

[0001] The utility model belongs to the technical field of slotting knives, and specifically refers to a multi-tooth counterbore composite-edge slotting knife. Background Art

[0002] In the field of modern machining, the demand for high-precision and high-efficiency machining is increasing day by day. Especially in industries such as aviation, automotive, and mold manufacturing, the requirements for machining tools are particularly strict. Traditional counterbore machining tools often have some deficiencies, which to a certain extent limit the improvement of machining efficiency and machining quality. First of all, traditional tools usually only have a single cutting function, such as only being able to perform rough machining or finish machining. This results in the need to frequently replace tools during the machining process, which not only increases the machining time but also raises the production cost. In addition, frequent tool replacement may also lead to the accumulation of errors during the machining process, affecting the accuracy of the final product. Secondly, the edge design of traditional tools is often relatively single and lacks adaptability to different machining stages. For example, during rough machining, it is necessary to quickly remove materials, while during finish machining, it is necessary to ensure the surface finish. A single edge design is difficult to meet these two requirements simultaneously. Moreover, the edge life of traditional tools is limited. Especially when machining high-strength and high-hardness materials, the edge wears quickly and needs to be frequently ground or replaced, which not only increases the maintenance cost but also reduces the production efficiency. Content of the Utility Model

[0003] In order to solve the above problems in the prior art, the utility model proposes that the first tooth of a multi-tooth counterbore composite-edge slotting knife is used for rough machining, the second tooth is used for semi-finish machining, and the third tooth is used for finish machining. The tool combines rough, semi-finish, and finish machining in one, ensuring the life of the tool edge while reducing the tool replacement time, and improving the machining efficiency and machining accuracy.

[0004] To solve the above technical problems, the technical solution adopted by the utility model is as follows: A multi-tooth counterbore composite-edge slotting knife includes a tool shank and a tool tip. Three teeth are evenly arranged around the tool tip. The three teeth include a first tooth, a second tooth, and a third tooth. The widths of the three teeth are all different. The width of the first tooth is W1, the width of the second tooth is W2, and the width of the third tooth is W3. The width relationship of the three teeth 3 is W1 < W2 < W3. The first tooth is used for rough machining, the second tooth is used for semi-finish machining, and the third tooth is used for finish machining. The tool combines rough, semi-finish, and finish machining in one, ensuring the life of the tool edge while reducing the tool replacement time, and improving the machining efficiency and machining accuracy.

[0005] Furthermore, three cutting edges are provided on each tooth. The outer side of each cutting edge is the main flank face, the left and right sides of each cutting edge are the side flank faces, and the side away from the tool shank of each cutting edge is the rake face.

[0006] Furthermore, the included angle between the rake face and the end face of the cutter head is β1, and the included angle between the rake face of each cutting edge of each cutter tooth and the end face of the cutter head is equal.
