The utility model is further illustrated below by way of specific embodiment.
Embodiment 1
A kind of bore hole blade of the little auxiliary angle of big tool cutting edge angle, including matrix 11 and blade 12, as shown in Figure 1 to 4, concrete structure is:
The end face of matrix 11 is the most identical with the shape and size of both bottom surfaces of blade 12, and the bottom surface of blade 12 is fitted on the end face of matrix 11 to constitute cutter hub 1, and cutter hub 1 is with blade 12 for end face with matrix 11 as bottom surface；
Blade 12 be shaped as centrosymmetric enclosed shape, the gabarit of blade 12 end face is cutting edge, the bottom of blade 12 cutting edge is provided with chamfered edge, the gabarit of blade 12 end face is determined as follows: described gabarit is sequentially connected with by least three cutting edges 2 and constitutes, every cutting edge 2 is all connected and composed by one end of a straight flange 21 and one end of an arc-shaped edges 22, at the tie point of straight flange 21 and arc-shaped edges 22, the angle between tangent line and the straight flange 21 of arc-shaped edges 22 is at 5 °～10 °, article one, the other end of the straight flange 21 of cutting edge 2 connects the other end of adjacent cutting edge 2 arc-shaped edges 22；
The side of cutter hub 1 is formed slopely inclined-plane from blade 12 to inside side, matrix 11 direction.
In the present embodiment: blade 12 selects polycrystalline cubic boron nitride to make；Cutting edge 2 has four；The inclined-plane that cutter hub 1 side is formed slopely to inside side, matrix 11 direction from blade 12 is divided into two-stage from blade 12, first order inclined-plane is 10 °～12 ° with the α in the angle i.e. Fig. 3 of the reference planes being perpendicular to blade 12 bottom surface, the present embodiment α takes 11 °, β in the angle on inclined-plane, the second level and first order inclined-plane i.e. Fig. 3 is 40 °～50 °, and the present embodiment β takes 45 °；The central angle of arc-shaped edges 22 is 40 °～50 °, and the present embodiment takes 45 °；If the radius of arc-shaped edges 22 is R, a diameter of r, R and the r of the inscribed circle of blade 12 end face are shown in shown in Fig. 2, then R ∈ [1.5r, 2r], and the present embodiment R takes 1.875r；
γ in chamfered edge i.e. Fig. 4 of the cutting edge bottom of blade 12 takes 25 °, and between blade 12 cutting edge, a in radius i.e. Fig. 4 of blunt circle takes 0.008mm.
