Description
Technical field
The present invention relates to a kind of industrial processes materials and parts more particularly to a kind of manufacture ultra-hard cutting tool by machining
Blank, 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
Superhard materials (referring to Fig. 1) are waited, are processed into the blade of cutter.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) 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, with made of this
The cutting anterior angle of cutter is small not sharp enough.In this regard, it is designed in industry using cutting edge inclination, but anterior angle angle can only 15 degree of ＜ (and spiral shells
Tool orthogonal rake is revolved generally 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, and 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.
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 often bad, if making elongated cylinder rotating tool, is easily broken due to bend resistance power deficiency,
Lead to tool failures.

In order to obtain the blank manufactured for ultra-hard cutting tool, the present invention provides a kind of manufacturing method, including：
In hard material (such as：Man-made polycrystalline diamond, hard alloy, cubic boron nitride and cermet) on had
The blade shape adult of through-hole, shape is such as：Tubulose or section are in " C " shape.Blade shape adult axial length is 1mm~150mm,
Outer diameter is 3mm~75mm,
Connector is arranged in the through-hole of blade shape adult so that the blade shape adult after processing assembles simultaneously with connector
It is combined (such as：Freezed using high frequency or the modes such as vacuum freezes) blank is made again.
Connector and blade shape adult assembling after connect with axis body again or process connector on axis body after, then with sword
After degree of lip-rounding adult assembles or connector connect with axis body, then with the assembling of blade shape adult.
The advantageous 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 apex sword, this causes cutter apex sword processing service life and processing effect to be all significantly improved.
The blank for being used to manufacture cutting element of the present invention, with the cutter of its manufacture, also with the hard of high-hardness, wearable
Material blade and the cutter hub portion with enough bend resistance power, this is but also cutter apex sword is processed service life, processing efficiency and added
Work efficiency fruit is all significantly improved.
Such as：Diamond is used to carry out apex sword processing to complex fiber material for cutter made of cutting edge forming layer, it can
To obtain the service life of about 4 times of coating diamond cutter and 3 times of processing efficiency.
