Specific embodiment
Cooperation diagram, the structure of the utility model and its technical characteristic are described in detail as after, wherein each diagram is only to illustrate The structural relation and correlation function of the utility model, therefore the size of each element not draws system and non-according to actual ratio in each diagram To limit the utility model.
Referring to figs. 1 to Fig. 6, the utility model is a kind of milling cutter construction 1, for carry out milling operation, the work to one Object includes printed circuit board, casing etc..The milling cutter construction 1 includes a milling work department 10 and a clamping part 20.
The milling work department 10 is made into integration by plycrystalline diamond diamond (PCD, Polycrystalline diamond) material, Wherein plycrystalline diamond diamond (PCD, the Polycrystalline diamond) material has high hardness, compression strength height, thermal conductance good And the advantage that wearability is good.In actual fabrication, block board of the tool compared with appropriate size is first made using plycrystalline diamond diamond material Body, then needed according to the actual size of the milling work department 10, which is cut into the member of a plurality of milling work department 10 Idiosome, then by each first one milling work department 10 of idiosome machine-shaping.
It, can be according to the milling work department on the outer fringe surface of the milling work department 10 of the milling cutter construction 1 referring to figs. 2 to 4 10 milling operation needs and the different burrs for being equipped with and having different Milling Functions is further processed, such as: netted ruling 10a is as schemed Shown in 2 or parallel lines 10b as shown in figure 3, or circular granular 10c as shown in figure 4, for manufacture end be able to cooperate different millings Job requirements select suitable burr 10a, 10b, 10c, but above-mentioned various burr 10a, 10b, 10c are non-practical to limit It is novel.Further, since the milling work department 10 of the milling cutter construction 1 is all by plycrystalline diamond diamond (PCD, Polycrystalline Diamond) material, which is integrally formed, is made, therefore as burr 10a, 10b, 10c on the outer fringe surface of the milling work department 10 When generating abrasion using a period of time, user remains to remake those again on the outer fringe surface of the milling work department 10 convex Line 10a, 10b, 10c enable the milling work department 10 to revert to the use state with burr 10a, 10b, 10c, so that should Milling cutter construction 1 may continue to using, the opposite service life for promoting the milling cutter construction 1, and relative reduction its cost of manufacture.
20 system of clamping part is clamped on a toolroom machine such as milling machine or drilling machine to engage energy supply with the milling work department 10 Upper use, wherein the clamping part 20 is processed into column steel 20a, and steel 20a includes stainless steel or wolfram steel but unlimited System.
Referring to figs. 1 to 4, which further includes a footstalk portion 21 and a middle section below the footstalk portion 21 It portion 22 but does not limit.In addition, further distinguishing on the top of the milling work department 10 and the opposite face of the bottom end of the middle portion 22 One joint face 11,23 is set with corresponding engagement but is not limited, so that the milling work department 10 can be engaged accurately with the middle portion 22 Integrally.
With reference to Fig. 1, the juncture of the milling work department 10 and the middle portion 22 further includes welding, welding and solder flux It engages but does not limit, since above-mentioned various junctures are the existing skill using this field up to winner, therefore do not go to live in the household of one's in-laws on getting married separately herein State its detailed juncture.In addition, referring to figs. 1 to Fig. 4, the bottom end in the footstalk portion 21 is further formed a conical neck 24 but not Limitation.
In addition, with reference to Fig. 5 and Fig. 6, the milling work department 10 further by an integrally formed plycrystalline diamond diamond (PCD, Polycrystalline diamond) bulk processes to be formed but not limited, and be conducive to increase manufacture end and manufacture milling work The process efficiency in portion 10;Wherein the clamping part 20, which is further processed by an integrally formed column steel 20a, forms but unlimited System;Wherein before column steel 20a is not yet processed, which first can directly engage with column steel 20a Integrally, the shape of column steel 20a is processed again after, is come flexibly with facilitating manufacture end to be able to cooperate different demands Adjust the structural shape of column steel 20a.Wherein, column steel 20a is further with the material of stainless steel or wolfram steel institute It is made but does not limit, be conducive to manufacture the material cost that end segment saves the production milling cutter construction 1.
The working substance further includes printed circuit board (not shown) or casing (not shown) but does not limit, by having The milling work department 10 of plycrystalline diamond diamond (PCD, Polycrystalline diamond) carrys out milling operation to obtain more excellent product The machined surface of matter, in addition, the milling work department 10 also can in addition to the milling operation that can apply on printed circuit board or casing Applied to the processing operation of auto parts or boat too part, to meet auto parts or boat too part high speed, efficient and high-precision Demand, so since milling operation is existing skill, and the demand emphasis of non-the utility model, therefore details are not described herein.
When the milling cutter construction 1 of the utility model is applied to the milling operation of printed circuit board, operating procedure is sketched such as Down but do not limit (not shown):
Step 1: the clamping part 20 of the milling cutter construction 1 being mounted on to the axle center of toolroom machine, then (is started with the rotation of high revolving speed Toolroom machine).
Step 2: the printed circuit board of one or more pieces stackings or casing are placed in the milling work department of the milling cutter construction 1 10 lower section (i.e. on the work top of toolroom machine), and the milling work department 10 alignment printed circuit board or casing are intended to process Working face.
Step 3: 10 high speed rotation of milling work department being made to carry out milling with the working face to the printed circuit board or casing Operation.
The milling cutter construction 1 of the utility model has the advantage that compared with the previous art of this field
(1), the milling work department 10 of the utility model milling cutter construction 1 is with plycrystalline diamond diamond (PCD, Polycrystalline Diamond) material is made into integration, due to the milling work department 10 of the milling cutter construction 1 be all by plycrystalline diamond diamond (PCD, Polycrystalline diamond) material integrated molding be made, be not only milling work department 10 outer fringe surface (such as Netted ruling 10a burr or parallel lines 10b burr or circular granular 10c burr) one strata crystalline substance diamond of coating (PCD, Polycrystalline diamond) material layer and oneself, therefore after used a period of time, when convex on the outer fringe surface After line 10a, 10b, 10c abrasion, which can still remake burr 10a, 10b, 10c on the outer fringe surface again, it is sufficient to Promote the service life and relative reduction its cost of manufacture of the milling cutter construction 1.
(2), since the milling work department 10 of the milling cutter construction 1 has high-wearing feature, therefore working substance can opposite be promoted (as printed Printed circuit board or casing) Milling Process face precision, therefore can effectively promote the working efficiency of milling operation.
(3), the milling cutter construction 1 of the utility model includes one by plycrystalline diamond diamond (PCD, Polycrystalline Diamond the milling work department 10 and a clamping part 20 made of steel 20a (such as stainless steel or wolfram steel) that) material is constituted, therefore The cost of manufacture of the milling cutter construction 1 can be efficiently reduced.
It is described above to be merely exemplary for the utility model, and not restrictive, those of ordinary skill in the art Understand, without departing from the spirit and scope defined by the claims, can many modifications may be made, variation or it is equivalent, but It falls within the protection scope of the utility model.
