Problems solved by technology

[0004] For the above-mentioned conventional milling cutters, since the cutting grooves and broken tooth grooves are symmetrically distributed along the cutter head according to certain rules, the cutting edges are also regularly symmetrically distributed. When performing plate milling operations, the movement of the cutting edge and teeth of the milling cutter also has certain rules. Cooperating with the milling machine spindle speed and feed speed, it may cause regular ripples on the edge of the milled plate instead of Flat board edge, resulting in insufficient quality of the board edge

Embodiment 1

[0037] The structure of the milling cutter is as image 3 and Figure 4 As shown, the cutting groove is a right-handed groove, the tooth-breaking groove is a left-handed groove; the random tooth groove is also a right-handed groove.

[0038] Wherein, the angle of the helix angle of the cutting groove is generally between 15° and 35°, the angle of the helix angle of the broken tooth groove is generally between -15° and -35°, and the helix angle of the random tooth groove The angle can be between 65° and 89°, more precisely, between (the angle of the helix angle of the cutting groove + 45°) ~ 89°, and at the same time, it is necessary to ensure that the angle from the helix angle of the broken tooth groove deviates by 10 ° above. The deviation from the helix angle of the broken tooth groove is to avoid the same trend of the random tooth groove and the broken tooth groove, otherwise the effect of destroying the regular and uniform distribution of the original cutting edge teeth...

Embodiment 2

[0041] The structure of the milling cutter is as Figure 5 As shown, the cutting grooves are right-handed grooves, the tooth grooves are left-handed grooves; the random tooth grooves are also left-handed grooves.

[0042] The choice range of the helix angle of the left-handed random tooth groove is larger, and the corresponding design freedom of the number of grooves is also large. Wherein, the angle of the helix angle of the cutting groove is generally between 15° and 35°, the angle of the helix angle of the broken tooth groove is generally between -15° and -35°, and the helix angle of the random tooth groove The angle can be between -15°~-89°, more precisely, between (the angle of the helix angle of the cutting groove -45°)~-89°, and at the same time, it is necessary to ensure that it is consistent with the helix angle of the broken tooth groove The angle deviates by more than 10°. The deviation from the helix angle of the broken tooth groove is to avoid the same trend of ...

Embodiment 3

[0045] The structure of the milling cutter is as Image 6 As shown, the cutting groove is a right-handed groove, the broken tooth groove is a right-handed groove; the random tooth groove is also a right-handed groove.

[0046] Wherein, the angle of the helix angle of the cutting groove can generally be between 15° and 35°, and the angle of the helix angle of the broken tooth groove can generally be between (the angle of the helix angle of the cutting groove+45°)~89°, The angle of the helix angle of the random tooth groove can be between 65° and 89°, more precisely, between (the angle of the helix angle of the cutting groove + 45°) ~ 89°, and at the same time, it is necessary to ensure that it is consistent with the broken tooth groove The angle of the helix angle deviates by more than 10°. The deviation from the helix angle of the broken tooth groove is to avoid the same trend of the random tooth groove and the broken tooth groove, otherwise the effect of destroying the regul...

Abstract

The invention discloses a cutter for milling high-quality plate edges and a processing method thereof. A set of spiral cutting slots and a set of spiral tooth breaking slots are arranged on a cutter head of the cutter for milling high-quality plate edges, wherein the spiral cutting slots are used for forming cutting edges, and the spiral tooth breaking slots are crossed with the cutting slots andused for breaking the cutting slots to form edge teeth; and a set of spiral tooth disordering slots respectively crossed with the cutting slots and the tooth breaking slots are also arranged on the cutter head. The cutter for milling high-quality plate edges in the invention is additionally provided with one set of tooth disordering slots, the spiral angles of the tooth disordering slots are different from the spiral angles of the cutting slots and the tooth breaking slots, the tooth disordering slots pass through the edge teeth formed by the cutting slots and the tooth breaking slots to formnew irregular tooth slots on the passed edge teeth ,and the regular and uniform distribution of the original cutting edge teeth is destroyed so that many cutting edges are not symmetrical any more. As the regularity of the edge teeth on the cutting edges of the milling cutter is destroyed by the tooth disordering slots, no periodical regularity exists when a plate is milled and cut so that the milled plate edges are flat without corrugations.

Description

technical field [0001] The invention relates to the technical field of milling cutter processing, in particular to a milling cutter with high plate edge quality and a processing method thereof. Background technique [0002] The cutting head portion of conventional milling cutters is usually formed by two sets of spiral grooves. One set of spiral grooves is the cutting groove forming the cutting edge, and the other set of spiral grooves is the breaker groove. The breaker groove intersects with the cutting groove, which is used to break the cutting groove and form the teeth, making the cutting part sharper and the chips thinner. crushed for easier discharge. [0003] For a right-handed milling cutter, the cutting groove is a right-handed spiral groove, and the broken tooth groove can be in the same direction as the cutting groove, that is, the same right-handed spiral groove, or it can be opposite to the cutting groove, that is A left-handed spiral groove. For milling cutte...
