Description
Technical field
The present invention relates to a kind of part for being used to manufacture cutting element, more particularly to a kind of cutting part, by superhard material
It is made, for being processed into the blade of cutting element.
Background technology
Tool Industry largely uses man-made polycrystalline diamond composite sheet in the form of annular discs and artificial cubic boron nitride composite piece
Deng superhard material (referring to Fig. 1), the blade of cutter is processed into.Traditional handicraft is that former disk is cut into required shape
(referring to Fig. 2) simultaneously freezes (such as：The methods of vacuum freezes or high frequency freezes) arrive tool matrix (such as：Hard alloy material and steel etc.)
Above (referring to Fig. 3).
These composite sheets can only be attached in plane (referring to Fig. 3), it is impossible to applied on spiral shape cutter, with made of this
The cutting anterior angle of cutter is small not sharp enough.On the other hand, designed in industry using cutting edge inclination, but anterior angle angle can only 15 degree of ＜ (and spiral shells
Tool orthogonal rake is revolved typically more than 30), cause cutter rigidly bad；Or multistage sword is used to imitate helical angle (referring to Fig. 9),
But manufacturing process is extremely complex, cost is also high.
Secondly as using discoid superhard material, its utilization rate is limited, can produce a large amount of leftover pieces, cause material
Waste.On the other hand, cutter manufacture industry realizes the reduction of production cost and price by constantly producing big diameter disc.
In addition, when cutter is needed using superhard materials such as cermet, diamond and cubic boron nitrides as blade, minor diameter
Cutter can not be manufactured directly using above-mentioned material, can only form coating on Manufactured small-diameter cutter by coating process,
All it is existing skill i.e. forming metal-cermic coating, diamond coatings or cubic boron nitride coating made of hard alloy on cutting edge
Art.But these coatings have common existing defects, such as：Coating its thickness there are about 0.002mm~0.01mm, and this causes tool blade
Portion's radius has to increase 0.004mm~0.02mm, and for precision cutting, the increase of radius of clean-up can greatly improve cutting resistance
Power, it can not only reduce surface to be machined quality but also cutter life can be reduced or directly fractureed；For another example：The knot of coating and blade
It is bad with joint efforts, particularly diamond coatings and cubic boron nitride coating, still the high-volume business application without maturation；And coating
The cost of cutter dramatically increases.
The content of the invention
It is an object of the present invention to provide a kind of superhard material cutting part, during shortening the manufacture of spiral shape cutter
Between, reduce manufacturing cost.
It is another object of the present invention to provide a kind of manufacture method of superhard material cutting part, to realize spiral shape
The manufacture of cutting part.
It is yet a further object of the present invention to provide a kind of cutter, and it is carried using spiral superhard material as cutting edge portion
High cutter life and processing efficiency.
A further object of the present invention is in the application in a kind of superhard material cutting part of offer in cutter manufacture.
A kind of superhard material cutting part provided by the invention, including
First surface and the second curved surface, the projection of first surface are justified along the first circle, the projection of the second curved surface along second,
First circle and the second circle are concentric circles；
3rd face, be spiral shape face, also simultaneously with first surface and the second surface intersection.
Superhard material is such as：Cermet, diamond (especially man-made polycrystalline diamond) and cubic boron nitride, or hard
Alloy and the composite of the formation of the one or more of cermet, diamond and cubic boron nitride.
To cross the axis of the first round heart as reference, cutting part thickness is 0.3mm~15mm, cutting part radial width
In 0.3mm~15mm, axial length is 0.8mm~150mm.
The spiral angle in the 3rd face of cutting part is 5 degree~75 degree.
In order to produce the various superhard material cutting parts of the present invention, a kind of manufacture method for also providing of the present invention, including：
The blank with cylindrical alien invasion is made (such as in superhard material：Tubulose, cylinder, cone and round pie),
Cutting tool carries out gyration along the axially cutting of blank, while always according to 5 degree~75 degree of spiral angle, so as to produce one
The cutting track of bar helical curve, and at least 2 cutting parts are produced, at least form 1 on 1 cutting part because of cutting
The swept surface of individual helical curve；
Obtained cutting part at least has 1 swept surface and two arc surfaces, and each described arc surface is parallel to each other,
Described swept surface intersects with two arc surfaces respectively, and intersection formed by intersection is helical curve.
The spiral shape cutting part of acquisition is fixed to by the knife slotted in advance by modes such as high-frequency welding or vacuum weldings
Have on matrix, cutter is processed into this.Material used in matrix is steel, hard alloy or tungsten alloy.
Tungsten alloy contains one or several metals of iron, copper and mickel, is specially：Ferro-tungsten, tungsten-copper alloy and tungsten nickel
Etc. high specific gravity high density tungsten alloy.These tungsten alloys are also containing one or more of metals such as chromium, manganese and cobalts, but be not Tool Industry
In be used to process the hard alloy of blade.
Each sword is formed with common grinding method to the matrix for securing helical blade (i.e. obtained cutting part) again
The rake face in portion and rear knife face, are made cutter.
The beneficial effect that technical solution of the present invention is realized：
Use superhard material cutting part provided by the invention can so that the life-span of cutter be significantly increased, using effect
It is greatly improved, such as：Aluminium alloy processing is carried out using using the cutter of spirality metal ceramic tip, can reduced
On the premise of 20% cost of charp tool, obtain and the approximate suface processing quality of straight sword PCD cutters and service life；Using spiral shape
The cutter of diamond blade carries out complex fiber material processing, can obtain about 4 times of coating diamond cutter life-span and 3 times
Processing efficiency.
