[0025] As Figure 3 shown, the embodiment of the present invention provides a tool for two-plane synchronous machining, which includes a tool shank 1, a tool body connected to the tool shank 1, and a cutting edge 3 installed on the tool body. The tool body includes an upper tool platform 21 and a lower tool platform 22. There is a spacing distance between the upper tool platform 21 and the lower tool platform 22, and the upper tool platform 21 and the lower tool platform 22 are connected by a connecting column 23.

[0026] The main bodies of the upper tool platform 21 and the lower tool platform 22 are in the shape of round cakes. Both the upper tool platform 21 and the lower tool platform 22 have a plurality of convex structures 24 extending radially outward along the tool. The plurality of convex structures 24 are evenly arranged in a circular array on the upper tool platform 21 or the lower tool platform 22. One side of each convex structure 24 is provided with a cutting edge installation slot, and each cutting edge installation slot is installed with a cutting edge 3. The cutting edge 3 is fixed on the convex structure 24 of the tool body by brazing. The upper tool platform 21 and the lower tool platform 22 are symmetrical structures up and down. The cutting edge of the cutting edge 3 installed on the upper tool platform 21 faces downward, and the cutting edge of the cutting edge 3 installed on the lower tool platform 22 faces upward.

[0027] Preferably, the upper tool table 21 and the lower tool table 22 are respectively provided with five convex structures 24, and the number of cutting edges 3 is ten.

[0028] The total length of the tool (as Figure 4 shown in f) is 100 - 120 mm. The edges of all the convex structures 24 on the upper tool table 21 are located at the same circumferential position, and the diameter corresponding to this circumference (as Figure 4 shown in d) is 45 mm - 50 mm. In this embodiment, d is 45 mm. The edges of all the convex structures 24 on the upper tool table 21 are located at the same circumferential position, and the size of this circumference is the same as the circumferential size of the upper tool table 21. The upper tool table 21 and the lower tool table 22 have the same thickness, and this thickness (as Figure 4 shown in a) is 5 mm - 8 mm. In this embodiment, a is 7 mm. The spacing distance between the upper tool table 21 and the lower tool table 22 (as Figure 4 shown in c) is 5 mm - 15 mm, and the specific value can be correspondingly set according to the size of the workpiece to be processed. The cutting edge 3 protrudes 0.02 mm - 0.8 mm from the surface of the upper tool table 21 or the lower tool table 22, and this protruding size is as Figure 4 shown as b in. The diameter of the tool handle 1 (as Figure 4 shown in e) is 15 mm - 30 mm. In this embodiment, e is 20 mm. The diameter of the connecting column 23 is less than or equal to the diameter of the tool handle 1.

[0029] Preferably, arc chamfers are respectively provided at the joints of the connecting column 23 with the upper tool table 21 and the lower tool table 22 (see Figure 5 R4 in), and such a smooth connecting surface is not easy to accumulate the dust and chips splashed by cutting. Arc chamfers are provided at the edges of the cutting edge 3 (see Figure 5 R3 in), which can reduce the cutting resistance and temperature concentration during the machining process, effectively reduce the wear and damage during the machining process, and extend its service life. Chamfers are provided at the upper edge of the upper tool table 21 and the lower edge of the lower tool table 22 (see Figure 5 R2 in), reducing the sharpness of the tool table edge, so that it is not easy to cause scratches when the staff takes it.

Due to the synchronous and symmetric cutting forces acting on the workpiece canceling each other out, the deformation amount of the product is reduced. Using the tool for machining two-plane synchronous machines in the embodiment of the present utility model can greatly improve the machining efficiency.
