Abstract

The invention discloses an integrated three-blade boring and milling tool, belongs to a metal cutting tool, and aims to provide a boring and milling dual-purpose tool which can conduct boring and milling and can reduce the number of times for replacing tools. The integrated three-blade boring and milling tool comprises a tool holder, a tool bar and a tool body, wherein the tool bar and the tool holder are fixedly connected into a whole, the tool body and the end of the tool bar are fixedly connected into a whole, the diameter of the tool bar (2) is smaller than the diameter of the tool body (3), three cutting blades (4) are evenly distributed at the end of the tool body (3), the front angle of each cutting blade is 8-15 degrees, the rear angle of each cutting blade is 4-6 degrees, and the auxiliary rear angle of each cutting blade is 3-5 degrees. By the adoption of the integrated three-blade boring and milling tool, time for mounting, demounting and grinding the tool is saved, the application range of the tool is expanded, and dual purposes of boring and milling are possessed.

Description

Integral type three sword boring and milling cutters
Technical field
The present invention relates to a kind of cutter, relate in particular to a kind of metal cutting tool.
Background technology
Boring cutter or milling cutter are all common metal cutting tools; Wherein, boring cutter is mainly used in hole processing, and milling cutter is mainly used in processing plane, step surface or groove.At present, widely used boring cutter mainly contains two classes: the first kind is monoblock type single-blade boring cutter, and its knife edge part is carbide alloy, and thermohardening is high, and the operator is easy to injure cutter hub when self sharpening; Equations of The Second Kind is machine folder boring cutter, and it is fitting machine clip blade on knife bar.Once the shortcoming of this two classes boring cutter is blade wearing and tearing or tipping needs again sharpening or change cutter, have frequent handling cutter, cutter can repeat the defects such as the sharpening number of times is few, service life is short.Moreover, traditional boring cutter can only carry out boring processing to hole, can not carry out Milling Process to plane, step surface or groove, and range of application is narrower.
Summary of the invention
For the above-mentioned defect existed in prior art, the present invention aims to provide a kind ofly can carry out boring processing, can carry out Milling Process again, and can reduce the integral type three sword boring and milling cutters of number of changing knife.
To achieve these goals, the present invention by the following technical solutions: the knife bar that it comprises handle of a knife, fixedly be connected as a single entity with this handle of a knife, and the cutter hub that fixedly is connected as a single entity of this knife bar termination; The diameter of knife bar is less than the diameter of cutter hub, is evenly distributed with three cutting edges in the termination of cutter hub, and the anterior angle of each cutting edge is that 8~15 °, relief angle are that 4~6 °, front clearance are 3~5 °.
The point of a knife of each cutting edge is in same level.
Compared with the prior art, the present invention is owing to having adopted technique scheme, be provided with three equally distributed cutting edges in the termination of cutter hub, therefore when wearing and tearing or tipping occur in a cutting edge, only need to unclamp for the screw that clamps handle of a knife, then rotate knife bar and another cutting edge is aligned and the peak in the machining hole center, adjust the distance of point of a knife decentre line and can again process; Saved the time of handling and sharpening cutter.In addition, due to the point of a knife of each cutting edge, simultaneously in minimum horizontal plane, so the present invention also can be used as milling cutter and uses, and expanded the scope of application.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the upward view of Fig. 1;
Fig. 4 is perspective view of the present invention.
In figure: handle of a knife 1, knife bar 2, cutter hub 3, cutting edge 4.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described:
As shown in Fig. 1~4: knife bar 2 fixedly is connected as a single entity handle of a knife 1 and cutter hub 3, is evenly distributed with three cutting edges 4 in the termination of cutter hub 3, and the anterior angle of each cutting edge is that 8~15 °, relief angle are that 4~6 °, front clearance are 3~5 °; The diameter of knife bar 2 is less than the diameter of cutter hub 3.In order to carry out Milling Process, the point of a knife of each cutting edge 4 is simultaneously in minimum horizontal plane.

Claims (2)

1. integral type three sword boring and milling cutters, the knife bar that comprises handle of a knife, fixedly is connected as a single entity with this handle of a knife, and the cutter hub that fixedly is connected as a single entity of this knife bar termination; It is characterized in that: the diameter of knife bar (2) is less than the diameter of cutter hub (3), in the termination of cutter hub (3), is evenly distributed with three cutting edges (4), and the anterior angle of each cutting edge is that 8~15 °, relief angle are that 4~6 °, front clearance are 3~5 °.
2. integral type three sword boring and milling cutters according to claim 1, it is characterized in that: the point of a knife of each cutting edge (4) is in same level.
