The specific embodiment
Embodiment 1:
Referring to Fig. 1-Fig. 4, this is the embodiment that chip area of the present invention does not connect.
Present embodiment is made up of cutter head 2 and handle of a knife 1, has chip area 4 on the cutter head 2, and has cutting edge 3, and the center of cutter head 2 has cutter head endoporus 22; And cutter head 2 be shaped as annular, this annular is meant that the outline of cutter head 2 is an annular.
The outside of the present invention cutting edge 31, inboard cutting edge 33 and transition cutting edge 32 can be selected arc or linear as required.In the present embodiment, transition cutting edge 32 is an arc, and outside cutting edge 31 is a linear with inboard cutting edge 33.Wherein, the length of outside cutting edge 31 is 0.7mm, and the length of inboard cutting edge 33 is 1.6mm, and the arc length of transition cutting edge 32 is 0.5mm.
The quantity of chip area 4 of the present invention is identical with the quantity of cutting edge 3, is four in the present embodiment, and chip area 4 is spaced apart with cutting edge 3.
