Abstract
A kind of positive and negative rotation direction milling cutter construction disclosed in this invention, including a handle of a knife and the milling section for being connected to the handle of a knife；The milling section has dextrorotation blade part and left-handed blade part, and intervenient chip volume groove.The milling cutter carries out fibrous material the staggeredly cutting of left hand direction and clockwise direction, staggeredly cutting can make the continuous fiber of any extending direction by agile cut-out, its hole wall of the hole formed on fibrous material or milling face impulse- free robustness, hole wall surface or milling face precision improvement.
Description
Technical field
The present invention is related with milling cutter, in more detail, espespecially applied to fibrous material drilling or milling face, can effectively reduce
Or hole wall or the burr in milling face are eliminated, make the milling cutter construction that hole side wall is in smooth surface.
Background technology
Fibrous material drills or milling face is using traditional one-way spiral milling cutter, its shortcoming is hole wall or milling mask hairiness
Thorn, surface accuracy are poor, it is necessary to implement flash removed processing.The reason for causing hole wall or milling face burr, mainly milling cutter is with list
To spiral equidirectional cutting fiber material, and fibrous material is interwoven with continuous fiber, and continuous fiber presents different
Extending direction, if the extending direction of fiber intersects with the hand of spiral of milling cutter, the cutting force of milling cutter by can be sharp act on fibre
Dimension, by the agile cut-out of fiber.Conversely, the cutting force of milling cutter can not effectively act on the non-fibre intersected with the milling cutter hand of spiral
Dimension, or even fiber is pullled, so that there is the cilium formed because pullling fracture in dimension fibre；In addition, the non-and milling cutter hand of spiral
Intersecting fiber, it is also possible to because in the spiral groove for milling cutter of escaping, and can not smoothly be cut.
The content of the invention
The invention solves single-screw milling cutter to fibrous material drilling or milling face, hole wall or milling face is set to produce burr
Problem.
The positive and negative rotation direction milling cutter construction of the present invention, including a handle of a knife and the milling section for being connected to the handle of a knife；The end of the handle of a knife
Not-go-end is the first end of the milling cutter, which plays the second end that head end is the milling cutter；The handle of a knife and the milling section have same
One Pivot axle；The surface of the milling section is equipped with an at least dextrorotation blade part and at least one left-handed knife around the Pivot axle
Blade, is the chip volume groove parallel with the Pivot axle between the dextrorotation blade part and the left-handed blade part；The right side
Rotary knife blade is equipped with several dextrorotation blades, which is equipped with several left-handed blades；The dextrorotation blade and the left-handed blade
There is a helical angle respectively with the Pivot axle.
Wherein, the angle of the helical angle of the dextrorotation blade and the helical angle of the left-handed blade may be the same or different.
Wherein, the dextrorotation blade and the left-handed blade have a knife face and a knife abdomen respectively, and the knife face and the knife abdomen intersect
Form all cutting edges；The knife face of the dextrorotation blade is towards the first end of the milling cutter, and the knife face of the left-handed blade is towards the milling cutter
Second end.Alternatively, second end of the knife face of the dextrorotation blade towards the milling cutter, the knife face of the left-handed blade is towards the of the milling cutter
One end.
Further, the surface of the milling section is equipped with two dextrorotation blade parts around the Pivot axle and two left-handed
Blade part, the dextrorotation blade part and the left-handed blade part are adjacent to each other, are between the two the chip volume groove.
The effect of of the invention：The milling cutter rotates, the dextrorotation blade and the left-handed blade make the milling cutter have at the same time it is left-handed and
The cutting power of dextrorotation., can be to being in that the continuous fiber of different extending directions is carried out because of intertexture when drilling to fibrous material
The staggeredly cutting of left hand direction and clockwise direction.Staggeredly cutting can make the continuous fiber of any extending direction by agile cut-out,
The hole formed on fibrous material or milling face, its hole wall or milling face impulse- free robustness, surface accuracy lifting.
