Description

For manufacturing the blank and its manufacture method of cutting element
Technical field
It is used to manufacture cutting element, more particularly to a kind of milling cutter the present invention relates to a kind of, thereon with curve sword.
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.In this regard, designed in industry using cutting edge inclination, but anterior angle angle can only<15 degree (and it is spiral Tool orthogonal rake is generally more than 30), cause cutter rigidly bad；Or multistage sword is used to imitate helical angle, but manufacturing process Extremely complex, cost is also high.
Secondly, industry multiple-cutting-edge tool can only be realized on major diameter cutter, and medium-small diameter generally can only single-blade cutting.
The content of the invention
It is an object of the present invention to provide a kind of blank for being used to manufacture cutting element, to manufacture fully hard material bottom The cutter of sword, the cutting portion outside diameter of the cutter is 0.3mm~75mm, and is made of superhard material, and has complete 2 sword Cylinder class cutter structure above.
Be used to manufacture the blank of cutting element it is another object of the present invention to provide a kind of, outside diameter for 0.3mm~ Realized on 75mm hard materials and make skew cutting cutter.
Be used to manufacture the blank of cutting element it is yet a further object of the present invention to provide a kind of, outside diameter for 0.3mm~ The manufacture of more pieces of swords is realized on 75mm hard materials.
A further object of the present invention is the method for providing a kind of blank of manufacture for manufacturing cutting element, in order to Blank is applied to the manufacture of cutter.
Cutter for machining field, such as：Aperture knife tool, milling cutter and boring cutter etc., its appearance is usually with overall presentation Cylinder is relatively conventional, also with the feature such as groove body and cutting end part.From processing efficiency angle, these cutters generally have 2 pieces Cutting edge above, cutting edge are also arranged at cutting end part more typically.
A kind of blank for being used to manufacture cutting element provided by the invention, including
Cutting edge forming layer, forms one end of cutting edge (also referred to as shear blade) and helicla flute thereon；
Body layer, forms the main body of helicla flute thereon；
Cutting edge forming layer is mutually stacked with body layer.
The material of body layer is hard alloy, steel or tungsten alloy, the tungsten alloy of more than prioritizing selection tungstenic 60w/w%.
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 cobalt, but be not Tool Industry In be used to process the hard alloy of blade.
The outside diameter of body is 3mm~75mm, especially 3mm~12mm.
Cutting edge forming layer is cylindric, its axial length is 0.3mm~8mm, and outside diameter is 0.3mm~75mm, and material is such as：People Make the one or more of polycrystalline diamond, cubic boron nitride and cermet.
In order to obtain the blank for manufacturing cutting element, the present invention provides a kind of manufacture method, including：
By hard material (such as：Man-made polycrystalline diamond, hard alloy, cubic boron nitride and cermet) it is cut into multiple circles Column grain, that is, be made cutting edge forming layer.Cylinder grain axial length is 0.3mm~8mm, and outside diameter is 0.3mm~30mm,
By the cylinder grain after processing by being combined (such as with body layer (interior cooling hole can be equipped with)：Freezed using high frequency Or vacuum such as freezes at the mode) blank is made.
In order to increase the combination of cylinder grain and body layer, cylinder grain bottom surface is processed, increases the contact area of bottom surface, Formed for example：V-type, convex shape and rack type, these shapes are used to increase the combination power for freezing fixed.
The beneficial effect that technical solution of the present invention is realized：
The blank for being used to manufacture cutting element of the present invention, with the cutter of its manufacture, has helical angle and complete hard Material shear blade, this causes cutter shear blade processing service life and processing effect to be all significantly improved.
Such as：Diamond is used to carry out shear blade processing to complex fiber material for cutter made of cutting edge forming layer, can be with The service life of about 4 times of acquisition coating diamond cutter and 3 times of processing efficiency.
