Description
Technical field
This utility model relates to super hard abrasive cutting tool, is specifically related to a kind of super hard abrasive band saw.
Background technology
Super hard abrasive band saw is to utilize certain technology by super hard abrasive such as diamond, CBN, PCD (glomerocryst Buddha's warrior attendant at present
Stone) etc. be bonded to band saw matrix border, form sharp otch.The most again bands for band is placed on cutting machine and cuts.Mesh
Front conventional super hard abrasive is diamond.Band-saw diamond is currently mainly made by electroplating technique.Its preparation principle
It is at band saw matrix border deposition metallic nickel, diamond particles embedding to be prepared from.
The thickness of existing superthin diamond band saw matrix has reached tens microns to hundreds of micron.Superthin diamond band saw is
Extend band saw all to use multilamellar cutting edge technology of preparing service life (i.e. on matrix, cutting edge contains more than 2 layers diamond platings
Layer, as shown in Figure 1), but multilamellar cutting edge weakens the superiority of ultra-thin band saw matrix greatly, ultra-thin with WINTER company
As a example by band-saw diamond, the basic thickness of ultra-thin band saw is 0.15-0.2mm, after being prepared as band-saw diamond, and diamond belt saw cuts
The thickness of sword has reached 0.7mm, and for 3.5 times of mother metal thickness, the ultra-thin superiority of its mother metal cannot be played at all.Cause
This, matrix thickness is the band saw use because of multilayer technique of 0.2mm, and joint-cutting, between 0.7-0.8mm, significantly limit ultra-thin
The range of band-saw diamond.Along with the expansion of ultra-thin band saw range, when cutting high value material, superthin section, should
Particularly problematic, such as: in semicon industry, the thickness of silicon chip is more and more thinner, the most basic between 0.2-0.4mm, cuts
When cutting, each displacement of scroll saw is 0.5mm, and the silicon chip of cutting is 0.3-0.35mm；Comparatively speaking, diamond belt saw cut
Silicon chip slice thickness disclosure satisfy that demand, but monolithic joint-cutting is about 0.7mm, is equivalent to cut a piece of waste a piece of, limits greatly
Band saw utilization in superthin section cutting.For high value material, for the material such as special cermacis, functional crystal, for subtracting
The loss of few material, is badly in need of a kind of superthin diamond band saw to meet the needs of this kind of materials processing.
Utility model content
The technical problems to be solved in the utility model be to provide one can reduce as far as possible cutting edge thickness with reduce cut
The super hard abrasive band saw of slot gap.
Super hard abrasive band saw described in the utility model, connects into, including by steel band initial and end, the matrix that annular is constituted, its
In:
Described matrix includes toothed region and continuous carcass portion, extends certain along toothed region thickness direction in the front of toothed region
Distance is formed through the first receiving space of toothed region height, extends certain along toothed region thickness direction at the back side of toothed region
Distance is formed through the second receiving space of toothed region height, and described first accommodates space prolonging on toothed region thickness direction
Stretch distance equal with the second receiving space extended distance on toothed region thickness direction；
Accommodate space, the second top accommodating space and toothed region first to be provided with containing superabrasive particles
Ultrahard abrasive layer.
Band saw described in the utility model accommodates space owing to first forming the first receiving space and second in toothed region, makes to surpass
Hard abrasive grain can be partially accommodated in the first receiving space and second and accommodate in space, thus effectively reduces in prior art
Because of the cutting edge thickness directly formed in matrix surface consolidation superabrasive particles, and then cutting gap can be reduced, reduce
The waste of machined material.On the other hand, after forming the first receiving space and the second receiving space, the thickness of toothed region has one
Determine the minimizing of degree so that it is be easily worn when exposed, be equivalent to add the coating diamond number of plies in the cutting direction, prolong
Grow the service life of band saw.
In technique scheme, the castellated shape of described toothed region can select as required, can be along steel
Continuous tooth with circumferentially continuous distribution, it is also possible to be half knuckle-tooth, the rake tooth being discontinuously distributed along steel band circumferencial direction, the ladder that falls
Shape teeth etc., by making the deficiency that different flute profiles declines with the binding force of cladding material after making up thinning matrix, thus solve to combine
The diamond coating that power causes not comes off problem.Profile of tooth uses existing conventional method to make, and generally uses cut
Or model straight forming method.
In technique scheme, applicant thinks when the first receiving space or second accommodates space at toothed region thickness direction
On extended distance to be the 40-50% of superabrasive particles granularity the most suitable.
In order to obtain ultra-thin super hard abrasive band saw, the steel band that thickness is thinner can be selected to make matrix, it is preferable that choosing
Width≤the 8mm of the steel band selected, thickness≤0.5mm, correspondingly, make the thickness≤0.5mm of matrix, the height of matrix obtained
≤8mm.When the thickness of matrix is with time highly in the range of above-mentioned restriction, and the height preferably controlling toothed region is 1.5-2mm.
In technique scheme, described superabrasive particles can be selected from diamond, cubic boron nitride and aluminium oxide
One or more compositions in Deng.When being chosen as diamond of superabrasive particles, preferably 140#-170# Buddha's warrior attendant
Stone.
Compared with prior art, feature of the present utility model is:
1, band saw described in the utility model accommodates space owing to first forming the first receiving space and second in toothed region, makes
Superabrasive particles can be partially accommodated in the first receiving space and second and accommodate in space, thus effectively reduces prior art
The middle cutting edge thickness because directly being formed in matrix surface consolidation superabrasive particles, and then cutting gap can be reduced, subtract
The waste of few machined material.
2, the toothed region of band saw described in the utility model is after forming the first receiving space and the second receiving space, its thickness
There is a certain degree of minimizing so that it is be easily worn when exposed, be equivalent to add coating diamond layer in the cutting direction
Number, extends the service life of band saw.
3, the thickness of cutting edge is the most identical to root from top, no matter in use whether band saw weares and teares, and joint-cutting width
Spend the most consistent.
