Described cutting edge also includes secondary segment of cutting, and described secondary segment of cutting is connected with main cutting section.
Described main cutting section include indent curve sword and tangentially to straight line sword, described curve sword is by several radian gradual changes and mutually the indent arcuate blade section of inscribe forms successively.
The curve sword of described indent and the blade tip of straight line sword are rounding structure, and rounding radii is 0.003～0.02mm.
The anterior angle of described main cutting section is 18～20 °, and the first relief angle of described main cutting section is 11～13 °, and the second relief angle of main cutting section is 26～30 °, and the 3rd relief angle of main cutting section is 36～38 °.
Described each cutting edge is formed with chip area each other.
Each explanation of nouns of this utility model is as follows:
Anterior angle: rake face (directly acts on the metal covering being cut) and the angle between basal plane (with the rotation axis coincident of cutter hub and the plane vertical with cutting plane) in cutting edge；
Relief angle: the angle between rear knife face (metal covering relative with rake face in cutting edge) and cutting plane；
Rotation axis: cutter hub adds man-hour, the central axis of rotation.
The beneficial effects of the utility model are:
1. the cutting edge of a kind of milling cutter of this utility model is from the leading section of cutter hub and around the rotation axis of cutter hub to the structure of left-hand screw, this structure is when ensureing that original overall size precision is constant, the milling cutter cutter that shakes in working angles can also be effectively reduced, improve working (machining) efficiency, reduce enterprise's production cost；
2. the main cutting section of a kind of milling cutter of this utility model and the left-handed dovetail configuration of rear composition, left-handed swallow-tail form Tool Design can reduce and change cutting Impact direction, and Impact direction is downward, it is ensured that phone housing work in-process will not move up and down, and reduces and shakes；
3. the main cutting section of a kind of milling cutter of this utility model and the left-handed dovetail configuration of rear composition, the chip chip removal that the course of processing produces is downwardly, chip and the surface of the work cut will not collide, and discharge effectively and timely, it is to avoid the course of processing causes the impact scratching workpiece.

Detailed description of the invention
Further illustrate below in conjunction with-5 pairs of this utility model preferred embodiments of Fig. 1:
A kind of milling cutter, including cutter hub 1, the handle of a knife 3 being connected with the posterior end 12 of cutter hub 1, cutter hub 1 is generally cylindrical body, rise and there is rotation axis, man-hour is added at milling cutter of the present utility model, handle of a knife 3 is held on machine tool chief axis equal controller, rotate centered by the rotation axis of cutter hub 1, it is provided with several cutting edges 2 in the leading section 11 of cutter hub 1, described cutting edge 2 is from the leading section 11 of cutter hub 1 and around the rotation axis of cutter hub 1 to the structure of left-hand screw, the structure of this left-hand screw is when ensureing that original overall size precision is constant, left-handed swallow-tail form Tool Design can reduce and change cutting Impact direction, Impact direction is downward, ensure that phone housing work in-process will not move up and down, effectively reduce the milling cutter cutter that shakes in working angles, improve the qualification rate of working (machining) efficiency and product, reduce enterprise's production cost.
