Specific embodiments

[0026] The technical solutions of the present application will be further described below in conjunction with specific embodiments, but the present application is not limited to these embodiments.

[0027] As Figure 1 and Figure 2 shown, in this embodiment, a composite tool is proposed, which includes a tool body. The tool body successively has a clamping part 11, a chip - blocking part 12, an edge - grinding part 13, a cutting part 14, and a grooving and milling part 15 from top to bottom. The edge - grinding part 13 is cylindrical and is used for grinding the product; the cutting part 14 is cylindrical, and a cutting edge 20 is provided on the cutting part 14; the grooving and milling part 15 is cylindrical, and the grooving and milling part 15 is used for grooving or milling the product.

[0031] A transition area 21 is provided between the grooving and milling part 15 and the cutting part 14, and the surface of the transition area 21 is streamline.

[0032] When grooving or milling the product is required, the transition area 21 can conduct the waste chips discharged from the grooving and milling part 15 upward, avoiding the waste chips directly hitting the bottom surface of the cutting part 14. At the same time, it can also conduct the waste chips in a diffusive manner, making it more convenient for the grooving and milling part 15 to discharge chips.

[0033] The cutting part 14 is provided with a first chip evacuation groove 16. The first chip evacuation groove 16 runs through the upper and lower ends of the cutting part 14 and is arranged in the right-hand helix direction for discharging waste chips downward. The number of the first chip evacuation grooves 16 is four, which can effectively improve the operation efficiency.

[0034] When cutting the product, the waste chips are discharged downward along the right-hand helix direction of the first chip evacuation groove 16, which can prevent the waste chips from damaging the product.

[0035] In addition, a liquid inlet hole 18 is provided at the top of the tool body, and a liquid outlet hole 19 is provided in the first chip evacuation groove 16. The liquid inlet hole 18 and the liquid outlet hole 19 are in through connection.

[0038] In this solution, a chip baffle part 12 is arranged above the edge grinding part 13 to prevent the waste chips generated by grinding from splashing upward into the tool holder chuck, playing a role in protecting the tool holder chuck. In order to improve the chip blocking effect of the chip baffle part 12, the lower end face of the chip baffle part 12 has a spherical arc structure or a chamfer structure.

[0039] For those of ordinary skill in the art, without departing from the inventive concept of the present utility model, several variations and improvements can still be made, and these all belong to the protection scope of the present utility model.
