Abstract
The utility model provides a milling cutter is found in high -efficient aluminium processing, includes handle of a knife and cutting portion, is provided with all teeth of chip groove and three helical cutting in the cutting portion, and the terminal surface of cutting portion forms the end tooth of three cutting, and three all teeth are first all teeth, the all teeth of second and the all teeth of third respectively, and the key is: the helical angle of three all teeth be 39 for the helical angle that varies, the helical angle of first all teeth, second week the helical angle of tooth be 40, the helical angle of the all teeth of third is 41. The resonance in the upright milling cutter course of working can be eliminated to the helical angle that varies and the angle between teeth that varies, and processing vibration reduces, and the anti ability of lacking that collapses of cutter is stronger, is particularly suitable for high -efficient processing (high rotational speed, height feed, the big metal volume of getting rid of), can improve machining efficiency, and the upright milling cutter of this kind of structure can also obtain better abrasion resistance and cutter life simultaneously.
Description
Technical field
The utility model belongs to cutting tool technical field, it relates to a kind of high-efficiency aluminum processing slotting cutter.
Background technology
Due to aluminium light weight, corrosion-resistant, resistance is little, the feature such as non magnetic, its application is widely. Intensity and the hardness of aluminium are lower, and cutting force is little, and processing temperature is low, belong to easy work material. But the fast development along with present production, the requirement of cutter is more and more higher, high-precision, efficient, low cost is processed into inevitable. Existing cutter generally adopts that the helix angle of 45 �� of helix angles, each week tooth is equal, spacing between each week tooth is equal, end tooth crosses center, adopts existing this kind of cutter can not meet the use needs of production.
Summary of the invention
The utility model, in order to overcome the defect of prior art, devises a kind of high-efficiency aluminum processing slotting cutter, while improving working (machining) efficiency, reducing tooling cost, also improves the quality of machined surface, meet the needs of modern manufacturing industry aluminium highly-efficient processing.
The concrete technical scheme that the utility model is taked is: a kind of high-efficiency aluminum processing slotting cutter, comprise handle of a knife and cutting portion, cutting portion is provided with junk slot and all teeth of three spiral cuttings, the end face of cutting portion forms three end teeth cut, three all teeth are respectively first week tooth, second week tooth and the 3rd week tooth, it is crucial that: the helix angle of three described all teeth is not equal helix angle, the helix angle of first week tooth is 39 ��, the helix angle of second week tooth is 40 ��, and the helix angle of the 3rd week tooth is 41 ��.
The end tooth corresponding with first week tooth is the first end tooth, the end tooth corresponding with second week tooth is the 2nd end tooth, it is the 3rd end tooth with the end tooth that tooth was corresponding in the 3rd week, angle between three end teeth is non-repetitional structure, the first angle between first end tooth and the 2nd end tooth is 116 ��, and the 2nd angle between the 2nd end tooth and the 3rd end tooth is 117 ��; The 3rd angle between first end tooth and the 3rd end tooth is 127 ��.
Three described end teeth meet at the center of cutting portion end face, are formed into division center.
The sword band of described all teeth is provided with cylinder sword band, and cylinder margin width is 0.03��0.08mm.
The beneficial effects of the utility model are: not equal helix angle and the tooth spacing angle such as not, the resonance in the slotting cutter course of processing can be eliminated, processing vibration reduces, cutter is anti-, and to collapse scarce ability stronger, it is particularly suitable for highly-efficient processing (high rotating speed, high feeding, big metal removal rate), can improving working (machining) efficiency, the slotting cutter of this kind of structure can also obtain better wearability and cutter life simultaneously.
Accompanying drawing explanation

In accompanying drawing, 1 represents handle of a knife, and 2 represent junk slot, and 3 represent week tooth, and 4 represent end tooth, and �� represents helix angle, ��1Represent the first angle, ��2Represent the 2nd angle, ��3Representing the 3rd angle, b represents cylinder margin width.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated:
Specific embodiment, as shown in Figure 1, Figure 2 and Figure 3, a kind of high-efficiency aluminum processing slotting cutter, comprises handle of a knife 1 and cutting portion, and cutting portion is provided with junk slot 2 and all teeth 3 of three spiral cuttings, the end face of cutting portion forms three end teeth 4 cut, three all teeth 3 are respectively first week tooth, second week tooth and the 3rd week tooth, and the pitch angle alpha will of three all teeth 3 is not equal helix angle, and the helix angle of first week tooth is 39 ��, the helix angle of second week tooth is 40 ��, and the helix angle of the 3rd week tooth is 41 ��.
The end tooth 4 corresponding with first week tooth is the first end tooth, the end tooth 4 corresponding with second week tooth the 2nd end tooth, being the 3rd end tooth with the end tooth 4 that tooth was corresponding in the 3rd week, the angle between three end teeth 4 is non-repetitional structure, the first angle �� between the first end tooth and the 2nd end tooth1It is 116 ��, the 2nd angle �� between the 2nd end tooth and the 3rd end tooth2It it is 117 ��; The 3rd angle �� between first end tooth and the 3rd end tooth3It it is 127 ��.
Not equal helix angle and the tooth spacing angle such as not, the resonance in the slotting cutter course of processing can be eliminated, processing vibration reduces, cutter is anti-, and to collapse scarce ability stronger, it is particularly suitable for highly-efficient processing (high rotating speed, high feeding, big metal removal rate), can improving working (machining) efficiency, the slotting cutter of this kind of structure can also obtain better wearability and cutter life simultaneously.
As to further improvement of the utility model, three end teeth 4 meet at the center of cutting portion end face, are formed into division center, it is possible to improve the running balance ability of slotting cutter when high speed cutting, too increase the intensity of cutter simultaneously.
