Specific embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Type implementation method is described in further detail.
Shown in reference picture 1, the utility model embodiment discloses a kind of multiple-cutting-edge postwave blade milling cutter, including handle of a knife 1, and is located at
The spiral chip flute 2 of the lower section of handle of a knife 1 and rear knife face have the rear wave-blade spiral cutting sword 3 of waveform concaveconvex structure.After the multiple-cutting-edge
Ripple blade milling cutter has 5~7 rear wave-blade spiral cutting swords 3, compared to common two-edged or four blade milling cutters, sets a plurality of cutting edge
Cutter overall structure can be made compacter, firm, cutter strength and stiffness in itself are favorably improved.
Additionally, in the case where single-blade cutting output is constant, the quantity for increasing cutting edge can correspondingly improve feeding per minute
Amount, so that processing efficiency is improved, it is time-consuming.Therefore, the milling cutter operating efficiency of 5 cutting edges is substantially better than common two-edged or four
Blade milling cutter.
However, as the increase of cutting edge quantity, the manufacture difficulty of cutter can also be increased therewith, being unfavorable for controlling cost.
On the other hand, with the increase of cutting edge quantity, the space of chip pocket can reduce on the contrary, be unfavorable for the discharge of chip.Cause
This, the quantity of cutting edge is not more many more is conducive to practical application.
Consider the factors such as processing efficiency, manufacturing cost, the chip removal of cutter, the quantity of cutting edge is limited in 5~7
In the range of can improve processing efficiency, cutter manufacture cost and chip removal can be taken into account again.
Waveform concaveconvex structure is set in the rear knife face of cutting edge, rear wave-blade, the waveform concaveconvex structure of postwave blade milling cutter is formed
Be conducive to point bits and a chip removal, the velocity of discharge of chip can be accelerated.The quick discharge of chip can take away the heat produced during cutting, drop
The heat build-up of low cutter, reduces the thermal wear of cutter.
Every the surface attachment of rear wave-blade spiral cutting sword 3 has nitrogen chromaking aluminized coating.The parts of aero-engine are closed for titanium
Golden material, and in the prior art, cutting tool coating material is generally nitrogen titanium aluminide or nitrogen titanizing aluminized coating, these cutters are in processing titanium
During alloy, because cutter and workpiece contain titanium elements, compatibility occurs in processing, the abrasion of cutter is extremely serious.
And metal titanium elements are free of in nitrogen chromated aluminum coating composition, it is to avoid in machining titanium alloy blade there is compatibility
The tool wear for causing.Under conditions of hardness is not reduced, red hardness and wearability are showed well nitrogen chromaking aluminized coating, cutting
, up to 1100 DEG C, frictional surface coefficient is also below nitrogen titanium aluminide and nitrogen titanizing aluminized coating for blade maximum temperature.
Preferably, the thickness of nitrogen chromaking aluminized coating is 0.002~0.003mm.

Sword spiral cutting sword 3.
Preferably, the repetition period T=1.0mm of the waveform concaveconvex structure of rear wave-blade spiral cutting sword 3.Further, respectively
The waveform concaveconvex structure of bar rear wave-blade spiral cutting sword 3 mutually staggers equal distance in a wave period.Can so have
Effect ensures the continuity of machined surface, while the axial force that cutter is subject to can also be decomposed, reduces the axial vibration of cutter.
Shown in reference picture 2 and Fig. 3, rear wave-blade spiral cutting sword 3 by Passivation Treatment, in rear wave-blade spiral cutting sword 3
Fillet 4 is provided with cutting edge.Due to the cutting edge concaveconvex structure in wave shape of multiple-cutting-edge postwave blade milling cutter, can be formed with the cutting edge many
At individual cusp, the i.e. crest of waveform concaveconvex structure.Cutting force suffered by such cusp work in-process is very big and processed
Cutter can produce vibration in journey, easily cause cutting edge collapse it is scarce.Therefore, the utility model is especially carried out to multiple-cutting-edge postwave blade milling cutter
Passivation Treatment, makes the cutting edge of cutting edge show a fillet 4, in the case where cutting ability is not influenceed, enhances cutting
The intensity of sword.
Preferably, the rounding radii value of rear wave-blade spiral cutting sword 3 is R0.03~0.05mm, under this parameter, can
Ensure the sharpness of cutter, the intensity of cutter is can guarantee that again.
Postwave blade milling cutter is by the i.e. crest work of projection of waveform concaveconvex structure, in order to improve postwave blade milling cutter
Overall stock-removing efficiency, the crest radius value of the waveform concaveconvex structure of rear wave-blade spiral cutting sword 3 is greater than trough radius value.
Preferably, the crest radius value of the waveform concaveconvex structure of rear wave-blade spiral cutting sword 3 is the 2~3 of trough radius value
Times.Further, the crest radius R1=0.8mm of the waveform concaveconvex structure of rear wave-blade spiral cutting sword 3, trough radius R2=
The difference in height h=0.4mm of 0.4mm, crest and trough.
The making material of the multiple-cutting-edge postwave blade milling cutter that the utility model is provided is the ultra-fine grain hard that amount containing cobalt is 12%
Alloy.It is 10% versatility material compared to amount containing cobalt, amount containing cobalt is 12% ultra-fine cemented carbide materials microstructure densification
Property and uniformity better than amount containing cobalt for 10% versatility material, on the premise of hardness is constant, substantially increase the bending resistance of material
Intensity, so as to improve the impact resistance of cutter.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all in this practicality
Within new spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in guarantor of the present utility model
Within the scope of shield.
