Under rotating speed, certain processing vibration frequency can be produced when cutting workpiece, when this processing vibration frequency and machining tool
Intrinsic frequency when reaching consistent, processing resonance will be produced, the appearance of this processing resonance can not only affect converted products
Quality, but also easily lead to workpiece and scrap and tool damage.
Currently in order to reducing the vibration in Milling Processes, it is proposed that can effectively disperse cutting force does not wait tooth milling
Knife, unequal blade spacing milling cutter is in High-speed machining, and the difference of two between cog tooth pitches is different to the impulse force of the latter tooth along its direction of rotation,
And the margin width and land front-and-back angle designed accordingly for different tooth pitches is there are currently no, milling cutter is caused easy using process
Wear damage.
Utility model content
The purpose of this utility model is to provide one kind not wait tooth wear-resistant milling cutter, and milling can be prevented effectively from High-speed machining
The resonance of knife and workpiece, while strengthening the rub proofness of milling cutter.
For achieving the above object, the utility model proposes not wait tooth wear-resistant milling cutter,
Including four cutters tooth along counterclockwise arrangement, the cutter tooth be followed successively by the first cutter tooth, the second cutter tooth, the 3rd cutter tooth and
4th cutter tooth, the circumference edge clearance angle of first cutter tooth, the second cutter tooth, the 3rd cutter tooth and the 4th cutter tooth be followed successively by 7 °, 9 °, 7 ° and
7 °, the relief angle of circumference sword second is followed successively by 24 °, 25 °, 21 ° and 24 °, circumference sword margin width be followed successively by 0.4mm, 0.3mm, 0.5mm and
0.4mm, the circumference angle of cutting edge of the cutter tooth is 10.5 degree, and the end sword angle between adjacent cutter tooth is different, from the first cutter tooth
For starting point, in the counterclockwise direction the end sword angle is followed successively by 91 °, 87 °, 92 ° and 90 °.
Further, tooth wear-resistant milling cutter is not waited described, first cutter tooth, the second cutter tooth, the 3rd cutter tooth and the
Knife face width is followed successively by counterclockwise 1.3mm, 1.0mm, 1.5mm and 1.3mm after the circumference sword of four cutters tooth.
Compared with prior art, the beneficial effects of the utility model are：The shear blade of slotting cutter is adopted and do not wait tooth angle design,
The irregular distribution of effective cutting point can be made, so as to disperse the centrality and order of cutting force, it is to avoid regular
Periodically cut force vibration；Additionally, according to the specific circumference sword margin width of tooth angle design and circumference edge clearance angle is not waited, fully
Impulsive force and angle of attack that different tooth angle degree blades are subject to are considered, so as to ensure that cutting edge on the basis of milling cutter is shockproof
Sharpness and blade intensity, improve the wearability and service life of stability, stationarity and the milling cutter of Milling Process.
Description of the drawings
Fig. 1 is the structural representation that the embodiment of the utility model one does not wait tooth wear-resistant milling cutter bottom surface；
Fig. 2 is the structural representation that the embodiment of the utility model one does not wait tooth wear-resistant milling cutter.
Specific embodiment
Tooth wear-resistant milling cutter is not waited to be described in more detail to of the present utility model below in conjunction with schematic diagram, wherein representing
Preferred embodiment of the present utility model, it should be appreciated that those skilled in the art can change the utility model described here,
And still realize advantageous effects of the present utility model.Therefore, description below is appreciated that for those skilled in the art's
It is widely known, and be not intended as to restriction of the present utility model.
As shown in Figure 1 to Figure 2, the utility model proposes one kind do not wait tooth wear-resistant milling cutter, including four along inverse time faller gill
The cutter tooth of cloth, the cutter tooth is followed successively by the first cutter tooth 1, the second cutter tooth 2, the 3rd cutter tooth 3 and the 4th cutter tooth 4, each cutter tooth
Anterior angle δ of circumference sword 4 is 10.5 °, and the angle of the end sword 5 of the adjacent cutter tooth is different, is that starting point edge is counterclockwise from the first cutter tooth
Angle described in direction is followed successively by α 1=91 °, α 2=87 °, α 3=92 ° and α 4=90 °.
In the present embodiment, the different then tooth pitches in bottom angle are different, in unequal blade spacing, two larger cutters tooth of tooth pitch, and edge
The impulsive force that latter of milling tool direction of rotation cutter tooth is born is larger, and the appropriate margin width that increases reduces after land simultaneously
Angle, can strengthen the intensity of cutter tooth；In the same manner, less two cutters tooth of tooth pitch, along latter of milling tool direction of rotation cutter tooth institute
The impulsive force born is less, suitably reduces margin width, while increasing land relief angle, it is possible to increase the sharpness of cutter tooth, helps
In making cutting more smooth, reduce resistance.
