DETAILED DESCRIPTION OF THE INVENTION

(5) Specific details and working conditions of a device provided by the present application will be given below in combination with the accompanying drawings.

(6) Embodiment 1: According to a wheel machining tool, a rough turning tool 3 and a finish turning tool 4 are arranged on two sides of a tool head 2 respectively and embedded into a tool groove in the tool head 2 through fastening screws 7. The primary declination angle of the rough turning tool 3 is 100, and the primary declination angle of the finish turning tool 4 is 90. The height difference a between the rough turning tool 3 and the finish turning tool 4 in the direction parallel to the axis of a tool shank 1 is 0.4 mm, the distance c between the rough turning tool 3 and the tool head 2 is 6 mm, and the distance b between the finish turning tool 4 and the tool head 2 is 4 mm. The rake angle of the rough turning tool 3 is set to 13, the rake angle of the finish turning tool 4 is set to 15, and the cutting edges of blades of the rough turning tool 3 and the finish turning tool 4 are distributed clockwise.

(7) According to the present application, the machining tracks originally completed using a rough turning tool and a finish turning tool are integrated on one tool, and the tool can simultaneously complete rough turning and finish turning by reasonably distributing the angles and the relative position relation of the rough turning tool 3 and the finish turning tool 4 for the actual machined blank, thereby saving the time when the turret returns to the origin, reducing the tool change time, saving the quick positioning time for one tool at the same time and achieving higher machining efficiency.

(8) The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teachings. The exemplary embodiments were chosen and described in order to explain certain principles of the invention and their practical application, to thereby enable others skilled in the art to make and utilize various exemplary embodiments of the present invention, as well as various alternatives and modifications thereof. It is intended that the scope of the invention be defined by the claims appended hereto and their equivalents.
