The receiving hole 13 of solid boss 6 is accommodated, blade fastener 11 can coordinate with solid boss 6 is locked at rotating knife by cutting tip 1
On body 10, though because the cutting tip 1 in above-described embodiment is small size, can also have intensity and impact resistance and
Positioning stablity, therefore, the cutting tool in the present embodiment, more bites can be installed on the cutter hub 10 of same diameter specifications
Piece 1, so as to improve the stock-removing efficiency of cutting tool.
In order to ensure that blade fastener 11 stable to the clamping of cutting tip 1 simultaneously reasonable distribution end face, side upper knife groove 12 are right
The chucking power of cutting tip 1, receiving hole 13 completely attaches to solid boss 6 in the side inside cutter hub 10, away from knife
Gap X is provided with side inside body 10, and is met：0.05mm≤X≤0.2mm, both ensured solid boss 6 can shift with
The locating surface of receiving hole is in close contact, and does not interfere with the positioning of cutting tip again, in the present embodiment, X=0.12mm.
In the present embodiment, blade fastener 11 includes a screw, and the side of cutter hub 10 offers screw thread with face intersection
Hole 14, screw is installed in screwed hole 14 and screw head is pressed into the indent teeth groove 62 of solid boss 6, blade fastener 11
Handling need not all take the space of cutter groove 12, and so as to reduce the appearance and size of cutting tool, screwed hole 14 sets cutter hub
10 sides and face intersection, handling cutting tip 1 are all very convenient.In addition to the mode of the present embodiment, cut according to cutting tool
The clamping direction of blade fastener 11 can also be arranged on end face or side by the difference of tool cutting edge angle when cutting, i.e., open screwed hole 14
It is located at end face or side.
Cutter groove 12 contacts with the lower surface 3 of cutting tip 1 and two of which side 4, and two sides 4 are in upper surface
Angle on 2 directions is γ, and blade fastener 11 clamps the direction cutting tip 1 for participating in positioning corresponding with the fastener 11
Angle between side 4 is γ ', and cutting tool is in cutting, when especially carrying out high-efficient cutting, completes basic load cutting
The cutting force that the cutting edge 5 of the side of cutter hub 10 is born is much larger than the cutting force of the face cutting edge 5 of cutter hub 10, in order to ensure cutter hub 10
On cutting tip 1 cutting when, blade fastener 11 produces enough folders based on machining condition to side, face cutting edge 5
Holding force, it should meet：γ/2<In γ '≤γ/2+15 ° of the present embodiment, γ '=γ/2+8 °.
Figure 10 to Figure 11 shows second of embodiment of cutting tool of the present invention, and the cutting tool in the embodiment is car
Cutting knife tool, a cutter groove 12, the cutting tip 1 being equiped with cutter groove 12 in second of embodiment, this reality are provided only with cutter hub 10
The blade fastener 11 applied in example is a screw, and cutting tip 1 is positioned from the intersection of end face or side, screw
The setting direction of center line can adjust according to the actual use situation of turning cutting tool.
In addition to the scheme in above-described embodiment, blade fastener 11 can also include two screws, the side of cutter hub 10 and
End face offers screwed hole 14, and screw is installed in screwed hole 14 and screw head is pressed into the indent teeth groove 62 of solid boss 6
It is interior.
