[0042] The rough machining section 401 of the reamer is preset at the front end of the blade portion 40 to control the finishing allowance and improve the finish of the reamed hole. The rough machining section 401 of the reamer is provided at the front end of the blade portion 40, so that the finishing allowance can be accurately controlled, which has a significant effect on improving the finish of the reamed hole and the tool life.

[0043] From the above description, it can be seen that the present application achieves the following technical effects:

[0044] In the embodiment of the present application, a reamer rough machining section 401 is pre-set at the end of the blade portion 40. By pre-setting the reamer rough machining section 401 at the front end of the blade portion 40, the finishing allowance is controlled and the finish of the reamed hole is improved, thereby achieving the purpose of accurately controlling the finishing allowance and significantly improving the finish of the reamed hole, thereby achieving the technical effect of improving the cutting accuracy of the tool and significantly improving the service life of the tool, thereby solving the problem that most existing reamers are single-diameter straight groove reamers with long grooves, poor rigidity and short service life; and the problem that the processing of high-precision holes and deep holes often cannot meet the requirements of the drawings, and the technical problem of poor overall consistency due to multiple welding.

[0045] Furthermore, the tool handle 10, the connecting portion 20 and the runout measurement ring 30 are integrated. It can be understood that by adopting an integrated structure, the effect of improving the structural strength can be achieved, and the effect of improving the service life can also be achieved.

[0046] Further, the connecting portion 20 is a connecting neck, the diameter of the connecting neck is smaller than the diameter of the tool handle 10 and the diameter of the runout measuring ring 30, and the diameter of the tool handle 10 is larger than the diameter of the runout measuring ring 30. It can be understood that a good matching effect can be achieved.

[0047] Furthermore, the blade of the blade portion 40 is densely toothed, and the number of the dense teeth is at least eight. It can be understood that the effect of improving cutting efficiency can be achieved. Preferably, the number of dense teeth is 10-blade dense teeth; the roundness and cylindricity requirements of hole processing can be significantly improved.

[0048] like Figure 3-4 As shown, the end of the reamer rough machining section 401 is provided with a reamer rough machining section cutting edge main angle 4011. It can be understood that a good rough machining cutting effect can be achieved.

Of course, the tool groove chip removal angle a can be determined according to the processing of different materials, and can achieve the effect of adapting to a variety of usage environments. By designing the front chip removal angle of the tool, the chips can also be discharged along the groove shape to discharge the iron chips. After the front chip removal design, the tool groove can be basically the same length as the blade, and the overall rigidity of the tool is enhanced; at the same time, each tool groove is provided with a cooling hole 60, and the temperature generated during cutting is reduced through the cold cutting hole, and the generated chips are flushed forward for chip removal, thereby improving the tool life.
