Embodiment
Below in conjunction with the accompanying drawings, the present invention is described in further detail.
As shown in Figures 1 to 7, the invention provides a kind of aluminium milling cutter, including cutter hub 1 and blade 2, the cutter hub 1 to be
Concentric multi-diameter shaft shape, the cutting diameter of cutter hub 1 are more than the diameter of shank 4, chip area 5, chip removal are circumferentially uniformly offered at cutter head 3
Blade installation slot 7 is offered in the side wall of side cutter hub 1 at groove 5, blade 2 is fastened on blade installation slot 7 by screw 6
On, the upper slitter blade portion of blade 2 close to cutter head end face stretches out cutter head end face, and the tool cutting edge angle a of cutting tool cutting angle is 9 °
To 13 °, the axial rake b of cutting tool cutting angle is+5 ° to+9 °, the radial rake c of cutting tool cutting angle
For -3 ° to -7 °.By a large amount of innovative designs early stage, and later stage many experiments and scene examination processing and debugging, most tool cutting edge angle at last
A is arranged to this scope and realizes the axial force that cutter is born in working angles to be more than radial load, and roughing feed function can be achieved,
Point of a knife tipping this phenomenon is effectively prevent when cutting parts are changed simultaneously, is effectively improved processing efficiency；Before axial direction
Angle b is arranged to positive rake angle, and is further set in the range of this, can reduce cutting resistance, reduces cutting vibration, and then can adopt
With bigger cutting linear velocity and bigger feed speed, processing efficiency can be effectively improved；Radial rake c angle is arranged to
Negative rake, and be further limited in the range of this, the impact resistance of cutter can be effectively improved, protects cutting edge roundness and point of a knife
Position is less likely to be damaged in working angles.The cooperation of these three angles can effectively reduce the glutinous bits phenomenon of cutter, improve and add
The finish of work aluminium material surface, while improve production efficiency.
Preferably, the tool cutting edge angle a of cutting tool cutting angle is 10 ° to 11 °, and axial rake b angle is+6 °
To+7 °, radial rake c angle is -4 ° to -5 °.Milling cutter is optimal from the cutting-tool angle cutting effect in the range of this.
Preferably, the quantity of the chip area 5 is 3, and the quantity of blade 2 is uniformly divided for 3 and along the circumferencial direction of cutter head 3
Cloth.So that overall structure is simple, while it is more suitable for aluminium cutting.
Preferably, the blade 2 is radially arranged along cutter hub 1, and the thickness of blade 2 is 4.76 ± 0.1mm.Ensureing to cut
During blade 2 itself have enough strength and stiffness on the basis of so that cutter overall structure is compacter.
Preferably, the blade 2 has three angles, and angle is connected with the arc curve between angle by evagination, remote on blade 2
The point of a knife of the central shaft of cutter head 3 is more than the radius of cutter hub 1 apart from the distance of the central shaft of cutter hub 1.
Preferably, the length of cutter hub 1 is 70mm, a diameter of 40mm at cutter head 3, a diameter of 20mm at shank 4.Actually make
During, the length of cutter hub 1 is 70 ± 0.2mm, a diameter of 39.9mm -40mm at cutter head 3, a diameter of at shank 4
19.98mm -20mm, ensure that whole cutter structure is simple, compact, attractive in appearance on the basis of meeting using function.
During use, milling cutter is arranged on milling machine, aluminium is placed on milling machine table, and aluminium is made in process
Feed motion, milling cutter rotate；Can also aluminium it is motionless, milling cutter is made to make feed motion while gyration, according to will
Aluminium milling is asked to be molded, whole process cutter is durable in use, and the surface quality milled out is good, and milling efficiency is high.
Certainly, the present invention can also have other various embodiments, ripe in the case of without departing substantially from spirit of the invention and its essence
