Description
Technical field
This utility model relates to lathe or the cutter field of boring machine, CNC machine, be specially a kind of can the inserted cutting tool of chip breaking.
Background technology
Need during machining to use cutting tool, the commonly used blade of current cutter is fixed on handle of a knife and makes, the mutual alignment relation made between rear blade and handle of a knife is also fixed therewith, it is impossible to adjust again, and often has the demand of fine setting blade time actually used due to reasons such as blade abrasions.Additionally, existing cutting tool lacks chip breaking ability, chip is often wrapped in cutter or surface of the work, scratches machined surface.
Utility model content
In order to overcome the defect of prior art, it is provided that a kind of simple in construction, easy to use, flexible adjustment, adaptable cutting element, the utility model discloses a kind of can the inserted cutting tool of chip breaking.
This utility model reaches goal of the invention by following technical solution:
A kind of can the inserted cutting tool of chip breaking, including handle of a knife and blade, blade is fixed on the outer end of handle of a knife, it is characterized in that:
Blade includes base and cutter blade, base is the polygon that limit number is not less than and each length of side is all equal, one drift angle place or two drift angle places of base are provided with insert groove, insert groove is cut from the outside of base towards the center of base, the bottom surface of insert groove and the bottom surface oblique of base, the projection on insert groove bottom surface of the insert groove end face end points is positioned at the inner side of insert groove bottom surface, and the front end of insert groove end face is the inclined-plane tilted outside insert groove；Cutter blade is embedded in the insert groove of base, and the outer rim of cutter blade and the outer rim of insert groove bottom surface flush.
Described can the inserted cutting tool of chip breaking, it is characterized in that: set: the angle between bottom surface and the base end face of insert groove is as α, angle between reverse extending face and the base top surface of insert groove front end of the top surface is β, then α takes 10 °～20 °, and β takes 50 °～80 °.
Described can the inserted cutting tool of chip breaking, it is characterized in that: base is rhombus.
When this utility model uses, when machining, while chip is cut, chip flows to the inclined-plane of the front end of insert groove end face by the front end face of cutter blade, and there is the effect increasing chip deformation on this inclined-plane, promote chip fracture, it is to avoid affect productive temp because chip is wound around workpiece.
The beneficial effects of the utility model are: simple in construction, easy to use, strong adaptability.
Accompanying drawing explanation
Fig. 1 is the front view of blade in this utility model；
Fig. 2 is the left view of blade in this utility model.
Detailed description of the invention
This utility model is further illustrated below by way of specific embodiment.
Embodiment 1
A kind of can the inserted cutting tool of chip breaking, including handle of a knife and blade 2, as depicted in figs. 1 and 2, concrete structure is:
Blade 2 is fixed on the outer end of handle of a knife, blade 2 includes base 21 and cutter blade 22, base 21 is not less than 3 and all equal convex polygon of each length of side for limit number, one drift angle place or two drift angle places of base 21 are provided with insert groove 211, insert groove 211 is cut from the outside of base 21 towards the center of base 21, the bottom surface of insert groove 211 and the bottom surface oblique of base 21, the projection on insert groove 211 bottom surface of the insert groove 211 end face end points is positioned at the inner side of insert groove 211 bottom surface, and the front end of insert groove 211 end face is the inclined-plane tilted outside insert groove 211；Cutter blade 22 is embedded in the insert groove 211 of base 21, and the outer rim of cutter blade 21 and the outer rim of insert groove 211 bottom surface flush.
In the present embodiment, if: the angle between bottom surface and base 21 bottom surface of insert groove 211 is α, and the angle between reverse extending face and base 21 end face of insert groove 211 front end of the top surface is β, then α takes 10 °～20 °, and β takes 50 °～80 °；
In the present embodiment, base 21 is rhombus；
In the present embodiment, base 21 adopts hard alloy to make, and cutter blade 22 adopts PCD material to make.
When the present embodiment uses, when machining, while chip is cut, chip flows to the inclined-plane of the front end of insert groove 211 end face by the front end face of cutter blade 22, and there is the effect increasing chip deformation on this inclined-plane, promote chip fracture, it is to avoid affect productive temp because chip is wound around workpiece.Other usings method are all same with embodiment 1.
