Between diameter gradually decrease to 9mm from 10mm and be gradually increased to 10mm again.
Further, the relief angle of each side cutting edge includes sequentially connected first sword line, the second sword line and third sword
Line, the first sword line are connect with end sword, are 5 ° with horizontal angle, the second sword line is with horizontal angle
14 °, the third sword line and horizontal angle are 23 °.
Further, the length of the first sword line in the horizontal direction is 0.05mm, and the second sword line is in level side
Upward length is 0.3mm, and the length of the third sword line in the horizontal direction is 1.2mm.
Further, the surface of the side cutting edge is equipped with purple titanium coating.
Further, the relief angle of each side cutting edge further includes the 4th sword line, and the 4th sword line is connect with third sword line,
It is 40 ° with horizontal angle.
Further, the surface of the end sword is equipped with graphene layer.
Further, the other end rounded corner of the knife handle.
Compared with the existing technology, a kind of four blade milling cutter provided by the invention gradually subtracts the helical angle of side cutting edge from 46 °
Small to 35 °, preferably disperse cutting resistance, effectively reduce cutting resistance, keep machining more brisk, improves the anti-of cutter
Vibration performance, can be carried out High-speed machining, high production efficiency.Meanwhile side cutting edge from the starting point of cutter head end face to cutter handle combining part
End point between diameter gradually decrease to 9mm from 10mm and be gradually increased to 10mm again, this design with a tight waist has quickly row
Bits, the small advantage of frictional resistance increase cutting-tool's used life, substantially reduce production cost.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples, in attached drawing:
Fig. 1 is the structural schematic diagram of four blade milling cutter provided by the invention；
Fig. 2 is the right side view of Fig. 1；
Fig. 3 is the portion the A partial enlargement diagram of Fig. 2.
Specific embodiment
Now in conjunction with attached drawing, elaborate to presently preferred embodiments of the present invention.
As shown in Figure 1, the present invention provides a kind of four blade milling cutters, including the knife handle 10 being mounted on collet chuck and it is located at knife handle 10
The cutter head 20 of one end, sets that there are four spiral side cutting edges 21 on cutter head 20, and one end of cutter head 20 is additionally provided with four end swords
22, the helical angle end point of the side cutting edge 21 from the starting point of cutter head end face to cutter handle combining part is gradually reduced from 46 °
To 35 °, preferably disperse cutting resistance, effectively reduce cutting resistance, keep machining more brisk, improves the antivibration of cutter
Performance can be carried out High-speed machining, high production efficiency.Meanwhile side cutting edge from the starting point of cutter head end face to cutter handle combining part
Diameter between end point gradually decreases to 9mm from 10mm and is gradually increased to 10mm again, and this design with a tight waist has quick chip removal,
The small advantage of frictional resistance increases cutting-tool's used life, substantially reduces production cost.
Specifically, three basic points, respectively starting point, intermediate point and end point are taken on Fig. 1 cutter head 20, it is right respectively
The helical angle answered be A1, A2, A3, wherein A1=46 ° > A2=40.5 ° > A3=35 °.The corresponding diameter of three basic points is respectively
D1=10mm, D2=9mm, D3=10mm.
As shown in Fig. 2, the relief angle of each side cutting edge 21 includes sequentially connected first sword line 1, the second sword line 2 and
Three sword lines 3, the first sword line 1 are connect with end sword 22, are 5 ° with horizontal angle a1, the second sword line 2 and horizontal angle
A2 is 14 °, and third sword line 3 and horizontal angle a3 are 23 °.When processing hole, the first sword line 1 has the work of polishing to hole wall
With.In addition, the second sword line 2 and horizontal angle a2 is 14 °, third sword line 3 and horizontal angle a3 are 23 °, are tied in this way
Structure increases the intensity of side cutting edge 21, in metal cutting process, is greatly improved the cutting output and cutting speed of cutter, from
And production efficiency is improved, reduce production cost.
As shown in figure 3, the length b1 of the first sword line 1 in the horizontal direction is 0.05mm, the second sword line 2 is in the horizontal direction
Length b2 be 0.3mm, the length b3 of third sword line 3 in the horizontal direction be 1.2mm.From the first sword line 1 to third sword line 3 with
Horizontal angle is gradually increased, while length in the horizontal direction is also gradually increased, and side can be further increased in this way by being located at
The intensity of cutting edge 21, while cutter vibration can be prevented.Second sword line 2 and third sword line 3 avoid hole there are also the effect of wall sky
The effect of wall.
In the present embodiment, the relief angle of each side cutting edge further includes the 4th sword line 4, and the 4th sword line 4 connects with third sword line 3
It connects, is 40 ° with horizontal angle a4, the length of horizontal direction is 3.2mm, is increasing the same of the intensity of side cutting edge 21
When also have the function of wall sky.
Further, the surface of side cutting edge 21 is equipped with purple titanium coating and can further increase when carrying out Milling Process
Its intensity, prolongs its service life.The other end rounded corner 5 of knife handle 10.When 10 clamping of knife handle is in collet chuck, 5 energy of rounded corner
