Abstract
The utility model discloses a kind of PCD milling cutters, belong to process tool technical field.A kind of PCD milling cutter, comprising: cutter head, the lateral surface of cutter head are equipped at least one wave sword tooth and at least one straight-tooth, wave sword tooth and straight-tooth and are spaced apart from each other setting along the circumferential direction of cutter head, and the radius of gyration of wave sword tooth is less than the radius of gyration of straight-tooth.For the PCD milling cutter of the utility model when being finished, straight-tooth only removes a small amount of surplus, and the surface quality processed is more preferable, and straight-tooth is not allowed easy to wear and collapses scarce, avoids due to tool changing and what is occurred connect tool marks, improves the quality of finished surface.
Description
Technical field
The utility model relates to process tool technical fields, and in particular to a kind of PCD milling cutter.
Background technique
At this stage, disclosed fibrous composite Milling Process Cutting tool is divided into solid carbide and PCD (plycrystalline diamond gold
Hard rock) cutter.In order to achieve the purpose that fibrous composite great surface quality, solid carbide are vertical frequently with staggeredly sword
Milling cutter or water chestnut flute profile slotting cutter.Whole hard alloy interlocks sword slotting cutter or water chestnut flute profile slotting cutter, although can achieve higher
Surface quality, but since cutter material itself limits, even if cutter life also can not be too long using coating technology.Service life asks
, in the processing of large-scale workpiece often therefore multiple tool changing particularly evident for the processing of large-scale workpiece is inscribed, is difficult to control at tool changing
Control surface quality, in addition generate it is serious connect tool marks, the industry stringent for certain surface quality requirements connects the generation of tool marks very
It may judge that the entirety of workpiece is scrapped.Existing PCD cutter is all made of straight sword, milling process cutting force direction phase using cutting edge
Together, can not divide bits, tooth easily collapse it is scarce, once a tooth, which collapses, lacks coarse be significantly affected.
Utility model content
The purpose of this utility model is to provide a kind of PCD milling cutters, when solving existing tool sharpening fibrous composite,
The problem of surface quality difference.
The technical solution that the utility model solves above-mentioned technical problem is as follows:
A kind of PCD milling cutter, comprising: the lateral surface of cutter head, cutter head is equipped at least one wave sword tooth and at least one straight-tooth, wave
Sword tooth and straight-tooth are spaced apart from each other setting along the circumferential direction of cutter head, and the radius of gyration of wave sword tooth is less than the radius of gyration of straight-tooth.
Wave sword tooth and straight-tooth is arranged simultaneously on the outside of cutter head in the utility model, and wave sword tooth strong shock resistance is not easy to collapse tooth,
Major part surplus in position to be processed on workpiece can be directly removed in processing, has the function of a point bits；Impact resistance later
Weaker straight-tooth removes a small amount of remaining surplus, is directly finished, and cutting edge is not allowed easy to wear and collapsed scarce.It is finished
Straight-tooth only removes a small amount of surplus, and the surface quality processed is more preferable, and straight-tooth is not allowed easy to wear and collapses scarce, avoids due to changing
Knife and occur connect tool marks, improve the quality of finished surface.
Further, above-mentioned wave sword tooth is consistent with the extension form of straight-tooth.
Further, the extending direction of above-mentioned wave sword tooth and the extending direction of straight-tooth press linear extension.
Further, the extending direction of the extending direction of above-mentioned wave sword tooth and straight-tooth is tilted with the axis direction of cutter head.
Further, the extending direction of above-mentioned wave sword tooth and the extending direction of straight-tooth press helix extension.
The PCD milling cutter of the utility model is in processing, inclined wave sword tooth and straight-tooth or the wave sword extended along helix
Tooth and straight-tooth are conducive to a point bits, and the material cut down is discharged between wave sword tooth and straight-tooth.
Further, above-mentioned wave sword tooth and straight-tooth are uniformly distributed along the circumferential direction of cutter head.
The circumferential wave sword tooth of the utility model and straight-tooth are in processing, the interval time one of blade and material
It causes, guarantees that process steadily carries out.
Further, the quantity of above-mentioned wave sword tooth and straight-tooth is 2.
The utility model has the following beneficial effects:
For the PCD milling cutter of the utility model when being finished, straight-tooth only removes a small amount of surplus, the surface matter processed
Amount is more preferable, and straight-tooth is not allowed easy to wear and collapses scarce, avoids due to tool changing and what is occurred connect tool marks, improves the matter of finished surface
Amount.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the PCD milling cutter of the utility model；
Fig. 2 is the structural schematic diagram of the cutter head of the utility model；
Fig. 3 is the structural schematic diagram in another direction of the cutter head of the utility model.
In figure: 10- cutter head；11- wave sword tooth；12- straight-tooth.
Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
Embodiment
Please refer to Fig. 1 to Fig. 3, a kind of PCD milling cutter, including the knife bar and cutter head 10 for clamping, the lateral surface of cutter head 10
It is set equipped with 2 wave sword teeth 11 and 2 straight-tooth, 12,2 wave sword teeth 11 and 2 straight-tooth 12 along the circumferencial direction uniform intervals of cutter head 10
It sets, and the radius of gyration of wave sword tooth 11 is less than the radius of gyration of straight-tooth 12, i.e. D1 < D2.Wave sword tooth 11 and straight-tooth 12 according to
Linear extension, and the axis direction of extending direction and cutter head 10 tilts.In the other embodiments of the utility model, wave sword tooth
11 and the quantity of straight-tooth 12 can also be 1,3 or 4 etc., the circumferencial direction uniform intervals along cutter head 10 are arranged；Wave sword tooth 11
When with straight-tooth 12 according to linear extension, inclined direction and angle are depending on the rotation direction of PCD milling cutter and velocity of rotation, with full
Foot is easy a point function for bits, it is clear that the extending direction of wave sword tooth 11 and straight-tooth 12 can also be parallel with the axis direction of cutter head 10.
In the other embodiments of the utility model, the extension form of wave sword tooth 11 and straight-tooth 12 can also be prolonged by helix
It stretches, the direction of helix and lead are more easier depending on the rotation direction and velocity of rotation of PCD milling cutter when processing with meeting
Divide the function of bits.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
