Abstract
The utility model discloses a twolip milling cutter, include that the handle of a knife reaches the cutter body formed at this handle of a knife one end, this cutter body is kept away from a terminal surface of handle of a knife is sharp portion, cutter body surface interval is equipped with two helical shape chip grooves, two the edge of chip groove is in the point position is put and is formed anterior angle and relief angle respectively, has the obtuse angle contained angle between this anterior angle and the relief angle and forms the fish tail angle promptly. This twolip milling cutter passes through double flute design and the design of fish tail angle to increase and grind the back of the body, thus reinforcing dust exhaust ability, suitably adjust simultaneously the angle of anterior angle and relief angle, improve milling cutter wear resistance, through changing the spiral angle and the sword length of side to solve flange burr phenomena.
Description
Technical field
The utility model relates to a kind of milling cutter, particularly relates to a kind of Double-edged milling cutter.
Background technology
Along with the innovation of pcb board material, many producers during processing PCB sheet metal forming,
Edges of boards burr phenomena can occur, so that milling cutter service life reduction, not only affect production
Efficiency, and processing cost is uprised.
Summary of the invention
In order to overcome drawbacks described above, the utility model provides a kind of Double-edged milling cutter, can
Solve edges of boards Burr Problem, improve blades wear energy simultaneously, improve the milling cutter life-span.
The utility model be the technical scheme is that one to solve its technical problem
Kind of Double-edged milling cutter, including handle of a knife and the cutter hub that is formed at this handle of a knife one end, this cutter hub is remote
End face from described handle of a knife is tip, and described cutter hub surface is interval with two spirals
The chip area of shape, the edge of two described chip areas is formed respectively in described apical location
Anterior angle and relief angle, have obtuse angle angle and i.e. form fish tail angle between this anterior angle and relief angle.
As further improvement of the utility model, described chip area is that helical angle is
30 °～the groove of 32 °.
As further improvement of the utility model, described anterior angle angle be 10 °～
20 °, described relief angles is 10 °～30 °.
As further improvement of the utility model, described cutter hub surface is provided with the mill back of the body.
As further improvement of the utility model, shank diameter is 3.175mm.
As further improvement of the utility model, described cutter hub a diameter of 0.8～
2.4mm。
The beneficial effects of the utility model are: this Double-edged milling cutter is designed by double flute and fish
Caudal horn designs, and increases the mill back of the body, thus strengthens dust discharge ability；Before the most suitably adjusting
Angle and the angle of relief angle, improve blades wear energy；By changing spiral angle and sword
The length of side, thus solve edges of boards burr phenomena.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation；
Fig. 2 is tip configuration schematic diagram described in the utility model.
In conjunction with accompanying drawing, make the following instructions:
1 handle of a knife 2 cutter hub
3 chip area 4 tips
5 anterior angle 6 relief angles
The 7 mill back ofs the body
Detailed description of the invention
Below in conjunction with accompanying drawing, a preferred embodiment of the present utility model is made specifically
Bright.But protection domain of the present utility model is not limited to following embodiment, i.e. in every case with this
The simple equivalence change that utility model application the scope of the claims and description are made
With modification, within the most still belonging to the utility model patent covering scope.
Refering to Fig. 1,2, a kind of Double-edged milling cutter, including handle of a knife 1 and be formed at this cutter
The cutter hub 2 of handle one end, this cutter hub is tip 4 away from the end face of described handle of a knife, institute
Stating cutter hub surface and be interval with two spiral chip areas 3, remainder is formed
The mill back of the body 7.The edge of two described chip areas forms anterior angle respectively in described apical location
5 and relief angle 6, there is between this anterior angle and relief angle obtuse angle angle and i.e. form fish tail angle.
Described shank diameter is 3.175mm, described cutter hub a diameter of 0.8～2.4mm.
Wherein, described chip area be helical angle be 30 °～the groove of 32 °, so
The problem that can effectively solve edges of boards burr.
The described anterior angle angle of milling cutter tip is set to 10 °～20 °, described relief angle
Angle is set to 10 °～30 °, and such structure is designed to improve the resistance to of milling cutter
Mill performance, improves the milling cutter life-span, adds the mill back of the body 7 simultaneously, improves dust discharge ability.
Thus, this Double-edged milling cutter is designed by double flute design and fish tail angle, and increases mill
The back of the body, thus strengthen dust discharge ability；The most suitably adjust anterior angle and the angle of relief angle, carry
High blades wear energy；By changing spiral angle and the sword length of side, thus solve edges of boards
Burr phenomena.
