Knife, including cutter hub, the cutter hub include knife bar and blade, and the head bottom surface of the knife bar is provided with crescent supporting, the knife
Chip curling groove is provided with before piece.
Preferably, the radius R of the chip curling groove is 8mm.
Preferably, the blade is using negative chamfered edge blade.
Preferably, the blade has five blades and six points of a knife.
Preferably, five blades of the blade are the first blade of order setting, the second blade, the 3rd blade, the 4th
Blade and the 5th blade, first blade are symmetrical arranged with the 5th blade using the center line of the 3rd blade as line of symmetry, institute
State the second blade to be symmetrical arranged using the center line of the 3rd blade as line of symmetry with the 4th blade, first blade and the second blade
The side of the 3rd blade is arranged on, the 4th blade and the 5th blade are arranged on the opposite side of the 3rd blade.
Preferably, the 3rd blade is flat sword.
Preferably, the angle ψ between first blade and line of symmetry is 55 ° ~ 60 °, second blade and line of symmetry
Between angle ω be 125 ° ~ 130 °.
Compared with prior art, the utility model has the advantages that：The utility model structure design is simple, closes
Reason, the intensity of cutter hub is big, and cut-out is efficient, and beneficial to the processing of tubulose pored component, reliable operation, precision are high, is worth pushing greatly
Extensively.
The utility model is described in more detail with reference to the accompanying drawings and detailed description.

Embodiment
For allow the utility model features described above and advantage can become apparent, special embodiment below, and coordinate attached drawing,
It is described in detail below.
As shown in Fig. 1 ~ 7, a kind of tubulose pored component cutter knife special, including cutter hub 1, the cutter hub 1 include knife bar 101
With blade 102, the head bottom surface of the knife bar 101 is provided with crescent supporting 2, volume bits is provided with before the blade 102
Groove 103；The crescent supporting 2 improves the intensity of cutter hub 1, it is often more important that high vibration during cutting is greatly reduced；
The chip curling groove 103 makes chip be discharged to a direction.
In the utility model embodiment, the radius R of the chip curling groove 103 is 8mm.
In the utility model embodiment, the blade 102 is using negative chamfered edge blade 102.
In the utility model embodiment, the blade 102 has five blades and six points of a knife, beneficial to scattered cutting
Power, improves the service life of cutter hub 1.
In the utility model embodiment, the first blade 104 that five blades of the blade 102 are set for order, the
Two blades 105, the 3rd blade 106, the 4th blade 107 and the 5th blade 108,104 and the 5th blade 108 of the first blade
It is symmetrical arranged using the center line of the 3rd blade 106 as line of symmetry, 105 and the 4th blade 107 of the second blade is with the 3rd blade
106 center line is symmetrical arranged for line of symmetry, and 104 and second blade 105 of the first blade is arranged on the one of the 3rd blade 106
Side, the 4th blade 107 and the 5th blade 108 are arranged on the opposite side of the 3rd blade 106.
In the utility model embodiment, the 3rd blade 106 is flat sword, and two points of a knife of the flat sword play smooth surface
Effect so that workpiece to be machined it is highly polished, and the chip for making cutting get off narrows, and will not be blocked in chip curling groove 103,
And it can prevent the roughness of knife and damage cut-out end face.
