Description
Technical field
The utility model relates to milling cutter technology more particularly to a kind of milling cutters for numerical control processing.
Background technique
In recent years, with the development of science and technology, requirement of the machinery manufacturing industry to machining accuracy is also higher and higher, milling cutter work
For a kind of machining Common Use Tools, structure not only decides the intensity of itself, service life, further determines and drill out workpiece hole
Error size and accuracy.Existing milling cutter outer diameter is small, itself design is not reasonable, and when roughing is easy to appear breaking feelings
Condition, while existing tool wear is fast, the service life is short.
Summary of the invention
The utility model provides a kind of milling cutter for numerical control processing, and the milling cutter service life is short in the prior art for solution, is easy disconnected
The technical issues of knife.
In order to solve the above-mentioned technical problem, technical solution adopted in the utility model are as follows:
A kind of milling cutter for numerical control processing, including knife handle and segment of cutting, the knife handle connect the segment of cutting, the knife
Handle and segment of cutting have same Pivot axle, and the segment of cutting includes four blades along the setting of Pivot axle spiral, institute
State the side knife surface of blade and the Pivot axle to be formed by helical angle be 35 °；The second relief angle of circumference sword of the blade is
10 °, the circumference angle of cutting edge of the blade is 8 °.
Further, plating is equipped with AlTiSiN protective layer on the outer surface of the segment of cutting.
Preferably, the circumference sword flank width of the blade is 0.45mm.
Preferably, the total margin width of circumference sword of the blade is 0.85mm.
Further, the shear blade anterior angle of the blade is 3 °, and the shear blade relief angle of the blade is 8 °, and the second relief angle of shear blade
It is 18 °.
Preferably, the angle of the shear blade back taper is 2 °.
Preferably, the diameter size is 3mm, and the blade is 3mm along the length of axis.
Preferably, the handle diameter size is 4mm, and milling cutter total length is 50mm.
Preferably, the segment of cutting and knife handle are integrally formed.
Preferably, the material of the knife handle is wolfram steel.
The utility model provides a kind of milling cutter for numerical control processing, including knife handle and segment of cutting, and the knife handle connects institute
Segment of cutting is stated, the knife handle and segment of cutting have same Pivot axle, and the segment of cutting includes setting along Pivot axle spiral
It is 35 ° that four blades set, the side knife surface of the blade and the Pivot axle, which are formed by helical angle,；The circumference of the blade
The second relief angle of sword is 10 °, and the circumference angle of cutting edge of the blade is 8 °.The utility model is made by the structural parameters of optimization milling cutter
The requirement that milling cutter not only meets client's Milling Accuracy is obtained, while also having the service life long, anti abrasive feature.

Specific embodiment
With reference to the accompanying drawing, the embodiments of the present invention is specifically illustrated, attached drawing is only for reference and illustrates use, not structure
The limitation of pairs of the utility model patent protection scope.
As shown in Figures 1 to 4, a kind of milling cutter for numerical control processing, including knife handle 1 and segment of cutting, the knife handle 1 connect institute
Segment of cutting is stated, the knife handle 1 has same Pivot axle 2 with segment of cutting, and the segment of cutting includes along 2 spiral of Pivot axle
It is 35 ° that four blades 3 being arranged, the side knife surface of the blade 3 and the Pivot axle 2, which are formed by helical angle,；The blade 3
Circumference sword the second relief angle r2 be 10 °, the circumference angle of cutting edge r1 of the blade is 8 °.Meanwhile it needing to throw blade surface
Light removes flash removed, enhances the intensity of cutting edge.
In the present embodiment, plating is equipped with AlTiSiN protective layer on the outer surface of the segment of cutting, which can be effective
The wearability of milling cutter is enhanced, the service life of milling cutter is increased.
In the present embodiment, the wide b=0.45mm of circumference sword flank of the blade.The total margin width of circumference sword of the blade
C=0.85mm.The shear blade anterior angle r5 of the blade is 3 °, and the shear blade relief angle r3 of the blade is 8 °, and the second relief angle of shear blade r4
It is 18 °, the angle of the shear blade back taper is 2 °.By the way that the shear blade angle and width of blade is rationally arranged, so that entire cutter is more
Add stabilization, more efficient operating.
Specifically, the diameter size a=3mm, the blade 3 are 3mm along the length of axis, and the handle diameter size is
4mm, milling cutter total length are 50mm.The segment of cutting and knife handle are integrally formed, and the material of the knife handle is wolfram steel, entire blade
Material is all made of wolfram steel.
In the present embodiment, milling cutter parameter is advanced optimized, so that circle where the inside endpoint of the shear blade of four blades is straight
Diameter size d=1.8mm.
Above disclosed is only the preferred embodiment of the utility model, and the right of the utility model cannot be limited with this
Protection scope, therefore equivalent variations made according to the patent scope of the utility model still belong to the model that the utility model is covered
It encloses.
