Detailed Description
In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the utility model.
As shown in fig. 1-4, the present application relates to a tri-flute knife. This three-flute sword includes: the tool comprises a tool handle 1 and a connecting section 2 fixedly connected with the tool handle 1, wherein a tool bit 3 is arranged at the top of the connecting section 2; the tool shank 1 is a clamping part of the tool, so that a good clamping effect can be realized, and subsequent cutting is facilitated; the connecting section 2 is an extension part 6 of the cutter, and can realize the effect of prolonging the cutter, so that the cutter can be deeply processed inside a part; the cutter head 3 is a part for processing and cutting parts, and can realize a good cutting effect; further, the cutter head 3 includes: the cutting tool comprises a first blade 31 and a second blade 32, wherein the first blade 31 and the second blade 32 are fixedly connected, a second bevel 33 is arranged between the first blade 31 and the second blade 32, and the angle of the second bevel 33 is 30 degrees. Good cutting processing effect can be realized, and thus the effect of improving the processing efficiency is realized.
A first bevel angle 4 is arranged between the tool bit 3 and the connecting section 2; by arranging the first bevel angle 4, the condition that the cutter and the part interfere with each other can be prevented, so that the part is damaged, and meanwhile, the effect of facilitating the cutting waste residues to enter the chip groove 5 can be realized; preferably, the angle of the first bevel 4 is 54 degrees. The best chip removal effect can be realized. The outer surface of the connecting section 2 is provided with three chip grooves 5 along the axial direction; the chip removal efficiency can be improved, and the effect of simultaneously processing the three-groove parts can be realized, so that the processing efficiency is improved; further, a first R angle 7 is arranged at the junction of the tool bit 3 and the connecting section 2, and the first R angle 7 is R0.08. The effect of smooth discharge of the cutting waste can be ensured.
