Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Accompanying drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that retouched
The embodiment stated is a part of embodiment of the utility model, rather than whole embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made is belonged to
The scope of the utility model protection.
It refer to Fig. 1-Fig. 5, the structural representation for the milling cutter that Fig. 1 provides for the utility model embodiment；Fig. 2 is Fig. 1 C
Partial enlargement structural representation；Fig. 3 is Fig. 1 A-A cross section structure diagrams；The milling that Fig. 4 provides for the utility model embodiment
The side structure schematic view of knife；Fig. 5 is Fig. 4 B-B cross section structure diagrams.
The milling cutter that the utility model embodiment is provided, including cutting portion 4, the top of cutting portion 4 are provided with spherical blade 11,
Spherical blade 11 includes rake face 6 and rear knife face 7 and the cutting edge 8 between rake face 6 and rear knife face 7；Cutting portion 4
It is provided with perisporium in the side edge portion 9 of a plurality of spiral extension vertically, side edge portion 9 and is provided with multiple Circular Nose Cutting Edges 10.Due to side
