Chip groove space is narrow, easily produces cutting to block, particularly cutting toughness preferable material（Such as stainless steel）.Each end tooth
Between angle use repetitional structure, during high-efficient cutting vibrations, noise it is big.The shank portion of milling cutter is typically staight shank
Type, and the multiplex spring clip set installation way of machining center milling machine, during in milling step or using compared with full depth, milling cutter is easy
Being extracted from handle of a knife causes part rejection.In addition, milling cutter is when processing is compared with deep groove, cutting fluid can not immediately reach slotting cutter
Cutting edge position, cutting edge cannot sufficiently be cooled down and lubricated, and the cutting near cutting edge can not timely be cut liquid band and walk, meeting
Accelerate the abrasion of cutting edge, cutting-tool's used life is reduced, so existing slotting cutter or Shortcomings.
Utility model content
Utility model purpose of the present utility model is：Can chip removal be unobstructed during highly-efficient processing, cutter hub will not be to downslide
Fall, and vibrations and noise are small, and cutter anti-tipping blade ability is strong.Simultaneously when processing is compared with deep groove, coolant can be reached immediately
Cutting edge position, makes cutting edge be cooled down and lubricated, and the cutting near cutting edge also can timely be cut liquid band and walk, and reduce cutting edge
Abrasion, improve production efficiency, extend a kind of efficient carbide end mill of cutting-tool's used life, it is existing to overcome
The deficiency of technology.
What the utility model was realized in：A kind of efficient carbide end mill, including set on handle of a knife and handle of a knife
Cutting tip, be provided with all teeth and helical flute on the cutting tip, the end face of cutting tip be provided with chip pocket and
End tooth, is provided with two symmetrical keyways with holes on the handle of a knife, latch, the handle of a knife are provided with two keyways with holes
It is internally provided with liquid flow through hole.
The end tooth is divided into the first end tooth, the second end tooth, the 3rd end tooth and the 4th end tooth.
Angle a between first end tooth and the second end tooth is 95, the angle b between the second end tooth and the 3rd end tooth
It is 85, the angle c between the 3rd end tooth and the 4th end tooth is 92.5, the angle d between the 4th end tooth and the first end tooth is
87.5.
Hole in the keyway with holes is cylindricality blind hole.
By adopting the above-described technical solution, the utility model compared with prior art, increased chip space, make cutting
Smoothly discharge；Angle between each end tooth reduces the vibrations in process and noise using not repetitional structure；Keyway bottom
There is cylindricality blind hole, keyway is used cooperatively with latch, it is to avoid the situation that cutter glides from hilt；Cutter hub inside sets liquid flow
Through hole, enables coolant to reach cutting edge position immediately, and cutting edge is cooled down and lubricated, and the cutting near cutting edge also can be timely
It is cut liquid band to walk, reduces the abrasion of cutting edge, further increase cutting-tool's used life, it is ensured that crudy and production
Efficiency.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, but not as new to this practicality
The limitation of type.
Embodiment of the present utility model：Set on a kind of efficient carbide end mill, including handle of a knife 2 and handle of a knife 2
Cutting tip 1, is provided with all teeth 5 and helical flute 4 on the cutting tip 1, the end face of cutting tip 1 is provided with chip pocket
3 and end tooth 9, two symmetrical keyways with holes 6 are provided with the handle of a knife 2, latch 7 is provided with two keyways with holes 6,
The handle of a knife 2 is internally provided with liquid flow through hole 8.
The end tooth 9 is divided into the first end tooth, the second end tooth, the 3rd end tooth and the 4th end tooth.
Angle a between first end tooth and the second end tooth is 95, the angle b between the second end tooth and the 3rd end tooth
It is 85, the angle c between the 3rd end tooth and the 4th end tooth is 92.5, the angle d between the 4th end tooth and the first end tooth is
