In above-mentioned, sequentially coaxially set using three identical milling cutter side tool bodies 2, can be with three identical millings of dismounting and change
The position of knife side tool body 2, so as to ensure that each layer tool wear degree is close, the use for playing fully and equably each blade is dived
Energy.
As shown in Figure 3, milling cutter side tool body 2 is circumferentially to be machined with least one spiral shell on cavity cylinder, its periphery
In step trough 10 together with least of spin slot 9, the present embodiment, helicla flute 9 and step trough 10 use four roads, and are uniformly distributed, often
Two cascaded surfaces that road step trough 10 is distinguished on adjacent one of helicla flute 9, step trough 10 are corresponding with the position of helicla flute 9.Rank
Two cascaded surfaces on terraced groove 10 are provided with side blade 3, and side blade 3 uses carbide chip, and passes through locking screw
Nail 4 is fixed on cascaded surface, i.e., milling cutter side tool body 2 has two row side blades 3 in the axial direction.
At least provided with two projections 11 on the end face of milling cutter side tool body 2, in the present embodiment, raised 11 using two, and
And be symmetrical arranged on the outer of heart through hole wherein, the projection 11 of intermediate layer and bottom milling cutter side tool body 2 is fitted with aligning spiral shell
Nail 7, the position by the precession of aligning screw 7 with screwing out the overall center of gravity of adjustment cutter, can adjust whole milling cutter center of gravity and fall
On centre of gyration line, so as to realize dynamic balancing of the cutter in the case of running at high speed.
In above-mentioned, helicla flute 9 can be not only used for chip removal can mitigate milling cutter own wt again, and its quantity can also be according to reality
Increased or decreased.Side blade 3 is provided with the cascaded surface of step trough 10, side blade 3 is located on different cascaded surfaces,
It can so make that there is overlapping region between two neighboring side blade 3, it is to avoid tool marks, milling cutter side tool body 2 are left on workpiece
Be machined with central through hole, i.e., it is internal to use cylindrical cavity structure to reduce the own wt of whole milling cutter.
In above-mentioned, a diameter of φ 70mm~φ 90mm of milling cutter side tool body 2, the present embodiment selects φ 80mm.Milling cutter side tool
Two side blades 3 in the side blade 3 of eight hard alloy, step trough 10 are had on body 2 in spiral distribution, its helical angle
For 25 °~30 °, it could so cause the formation helical form of side blade 3 that three milling cutter side tool bodies 2 are corresponding, the present embodiment choosing
With 28 °, the shape of bionical pineapple is the helix on bionical pineapple, and then is realized by sword processing.Helicla flute on milling cutter side tool body 2
9 spiral angle is 38 °~50 °, and the present embodiment selects 40 °.
As shown in figures 4 and 5, milling cutter collet 1 is frustum, and its bottom surface is machined with convex with top layer milling cutter side tool body 2
11 mounting grooves 12 coordinated are played, end face center is machined with counterbore thereon, and counterbore stretches out to form lightening grooves 13.Its side is processed
There is the deep-slotted chip breaker 14 corresponding with helicla flute 9 on top layer milling cutter side tool body 2 and the position of step trough 10, that is, employ fairshaped outer
Shape is designed, and reduces gas-flow resistance during cutting, the buzzer that reduction is sent when rotating at a high speed.In the present embodiment, deep-slotted chip breaker 14 is adopted
With equally distributed four road.
End face blade 15 is respectively arranged with the bottom surface of milling cutter collet 1 and positioned at the top outer of per pass deep-slotted chip breaker 14, i.e.,
Its bottom surface, which is provided with least one end face blade 15, the side of milling cutter collet 1, is provided with least one bevel blade 16.This reality
Apply in example, its short transverse is provided with two bevel blades 16 on the side of the milling cutter collet 1 between adjacent deep-slotted chip breaker 14.
In above-mentioned, end face blade 15 and bevel blade 16 are fixed on the cutter groove of milling cutter collet 1 by lock-screw 4 respectively
On.Two rows, eight bevel blades 16 and four end face blades 15 are had on milling cutter collet 1, the cutting of inclined-plane and end face can be carried out
Processing, both quantity can be increased or decreased according to actual needs.
Integral position relation：Three milling cutter side tool bodies 2 are sequentially coaxially set, the helicla flute 9 of three and the position of step trough 10
Put corresponding and be interconnected, the helicla flute 9 and step trough 10 of same position is formed complete helicla flute and step trough, and make
Side blade 3 in step trough is in spiral distribution.Top layer milling cutter side tool body 2 passes through projection 11 thereon and the peace of milling cutter collet 1
Tankage 12 coordinates.
The course of work of the present invention is as follows：
Before machining is carried out, experiment of dynamic balancing, regulation intermediate layer and bottom are carried out to milling cutter on dynamic balancing machine
The position of four aligning screws 7 on milling cutter side tool body 2, enables whole milling cutter to reach the requirement for dynamic balance under high rotating speed.Will
Milling cutter collet 1 and blade are fixed on machine tool chief axis entirely through handle of a knife 8, in working angles, make milling cutter rotation at a high speed, by workpiece
It is fixed on below main shaft.
When carrying out side cut processing, because the side blade 3 in milling cutter blade on three milling cutter side tool bodies 2 is in spiral shell
Shape distribution is revolved, milling cutter side tool body 2 will participate in wood cutting by sword, cutting workpiece can be reached and reduce cutting force and improve and cut
The purpose of quality.If workpiece size is smaller, machining for a period of time after, the side knife on the milling cutter side tool body 2 of bottom
Piece 3 causes wear extent larger always involved in cutting, can now stop cutting, and re-assemblied, you can to change three
The position of milling cutter side tool body 2, top layer is changed by bottom milling cutter side tool body 2, so as to reduce the upper side knife of bottom milling cutter side tool body 2
The degree of wear of piece 3, makes each milling cutter side tool body 2 wear and tear close, can so extend cutting-tool's used life, improve cutter
The utilization rate of material.
Added by the end face and inclined-plane of 16 pairs of cutting materials of the end face blade 15 on milling cutter collet 1 and bevel blade
Work.
In summary, presently preferred embodiments of the present invention is these are only, is not intended to limit the scope of the present invention.
Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., should be included in the present invention's
Within protection domain.
