Description
Technical field
The utility model is related to a kind of industrial processes materials and parts, more particularly to one kind by machining to manufacture superhard skiver
The blank of tool, to realize the manufacture to curve sword superhard cutter.
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 method such as vacuum freezes or high frequency freezes) to 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, be made with this
The cutting anterior angle of cutter is small not sharp enough.In this regard, using cutting edge inclination design in industry, but anterior angle angle can only 15 degree of ＜ (and spiral shells
Revolve tool orthogonal rake general 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, industry multiple-cutting-edge tool can only be realized on major diameter cutter, and medium-small diameter typically can only single-blade cutting.
Again, hardness is more than the hard material of hard alloy (such as：Cermet, diamond and cubic boron nitride) although resistance to
Mill, but toughness is not often good, if making elongated cylinder rotating tool, easily because bend resistance power is not enough and is broken,
Cause tool failures.

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 not Tool Industry also containing one or more of metals such as chromium, manganese and cobalt
In be used to process the hard alloy of blade.
The external diameter of axis body is 3mm~75mm, especially 3mm~12mm.
A kind of embodiment of blade shape adult, its generally tubulose, its axial length is 1mm~150mm, and external diameter is
3mm~75mm, material is such as：The one or more of man-made polycrystalline diamond, cubic boron nitride and cermet.
The embodiment of another blade shape adult, its side elevation is provided with notch, and notch is connected with through hole.Edge and blade shape
Section obtained from adult is axially orthogonal is in " C " shape.
Various cutters are manufactured with the various blanks that the utility model is provided, such as：Elongated rotating tool.
The beneficial effect that technical solutions of the utility model are realized：
It is of the present utility model to be used to manufacture the blank of cutting element, with the cutter of its manufacture, with helical angle and complete
Hard material tip sword, this make it that cutter tip sword processes the life-span and processing effect is all significantly improved.
The blank of the present utility model for being used to manufacture cutting element, with the cutter of its manufacture, also with high-hardness, wearable
Hard material blade and cutter hub portion with enough bend resistance power, this also causes cutter tip sword to process life-span, processing efficiency
All it is significantly improved with processing effect.
For example：The cutter that diamond is made for cutting edge forming layer is used to carry out tip sword processing to complex fiber material, can
With obtain about 4 times of coating diamond cutter life-span and 3 times of processing efficiency.
