Embodiment is not limited to this.
As shown in Figure 1 and Figure 2, embodiment one is a kind of milling cutter, including milling arbor 1 and blade part 2, shown milling arbor 1 with
And blade part 2 is integrated, the blade part 2 includes the first blade 21, the second blade 22 and third blade 23, and described first
Blade 21, the second blade 22 and third blade 23 are distributed in one end of milling arbor 1 around 1 axis uniform spiral of milling arbor, described
A through-hole 3 is offered inside milling arbor 1 in the axial direction, the metal siphunculus 4 of a hollow structure, institute are arranged in the through-hole 3
It states milling arbor 1 and the opposed one end of blade part 2 is provided with the milling cutter interconnecting piece 5 being connected with milling machine, the milling cutter interconnecting piece 5
On both sides of the middle is provided with lateral concave inward structure 51.
More specifically, in embodiment one, the metal siphunculus 4 is aluminium alloy or magnesium alloy material, and general milling cutter uses tungsten
Steel material, and the heat dissipation performance of aluminium alloy or magnesium alloy materials is more preferable, so being embedded in one in the middle part of milling cutter with hollow structure
Metal siphunculus 4, be conducive to improve whole heat dissipation effect, reduce the internal temperature of milling cutter.
More specifically, in embodiment one, the metal siphunculus 4 is designed as the shape to match with through-hole 3, the metal siphunculus
4 are interference fitted with through-hole 3, and wherein metal siphunculus 4 is the cylindrical body with hollow structure, can also be circular cone structure, when assembling
Metal siphunculus 4 is pressed into through-hole 3 from one end is bonded the two tightly.
As shown in figure 3, embodiment two is another milling cutter, and compared with embodiment one, unlike embodiment two, the gold
Belong to siphunculus 4 and be provided with external screw thread 41,3 inner wall of through-hole is provided with the internal screw thread (not shown) to match with metal siphunculus 4, described
Metal siphunculus 4 is screwed onto the inside of through-hole 3；Metal siphunculus 4 and through-hole 3 are cylindrical, and the interference relative to embodiment one is matched
