Then, manufacture method about scribe wheel 40 is described.Scribe wheel 40 is formed by superhard alloy or sintering diamond.Perhaps, using base material such as superhard alloy to apply mechanically resistant material film such as (coating) diamond also can.For example, the scribe wheel 40 of sintering diamond system is mainly by diamond particle and constituting mutually by additive and in conjunction with the combination that material constitutes by rest part.
The median size of this diamond particle adopts below the 1.5 μ m.And diamond content is the scope of 75.0-90.0vol% in the sintering diamond.
As additive, can suitably use the ultramicron carbide that for example is selected from least a above element in tungsten, titanium, niobium, the tantalum.Ultramicron carbide content in the sintering diamond is the scope of 3.0-10.0vol%, and this ultramicron carbide comprises the titanium carbide of 1.0-4.0vol% and the wolfram varbide of rest part.
As in conjunction with material, can suitably use iron family element ting usually.As iron family element ting, for example cobalt, nickel, iron etc. are enumerated, wherein also with cobalt for more suitable.In addition, the content in conjunction with material in the sintering diamond is preferably the rest part of diamond and ultramicron carbide, is more preferred from the scope of 20.0-20.5vol%.
And, at first, mix above-mentioned diamond particle, additive, in conjunction with material, in diamond is become under the high temperature and ultra-high voltage stable on the thermodynamics, with these mixture sinterings.Make the sintering diamond whereby.When this sintering, the mould inner pressure of ultra-high voltage generation device is the scope of 5.0-8.0GPa, and temperature is 1500-1900 ℃ scope in the mould.
Then, by the sintering diamond that manufactures cut become desire the plectane of radius.And, in the circumference of this plectane, finish by cutting the two sides side respectively and to have the roughly scribe wheel 40 of the blade 42 of V word shape of the section that forms with 2 scarp 42a.
And, with respect to the blade front end 43 of the crest line that becomes this scribe wheel 40, make discoideus grinding stone butt to become orthogonal manner, form the groove 44 of U word shape shown in Fig. 4 (a) whereby in blade front end 43.At this moment, the bottom 44a of this groove 44 becomes width W shown in Fig. 4 (b).In addition, groove 44 of every formation then withdraws from grinding stone.
And, scribe wheel 40 is only rotated be equivalent to the rotation angle of both determining deviations after, again with the grinding stone butt, form next groove 44 whereby.So carry out and in the front end of the blade 42 of scribe wheel 40, so that blade front end 43 and groove 44 equidistantly alternatively to be set.In addition, because groove 44 becomes U word shape, bottom 44a becomes wire (toward the wire of scribe wheel 40 thickness T h directions extension), but become planar mode with bottom 44a groove 44 also can for rectangular-shaped.Further, the bottom 44a of groove is parallel with respect to the turning axle of scribe wheel, even but also can for inclination with respect to turning axle.
Then, to the scribe wheel 40 that is formed with this groove 44, be the direction of Fig. 4 (b) arrow C from the preceding apparent direction of blade front end 43, each irradiating laser in 44a both ends, the bottom of groove 44, part from bottom 44a periphery cutting blade 42 forms recess 46 whereby.
At this moment, the recess 46 of formation forms the central side that exists towards communicating pores 45 along with from bottom 44a shown in Fig. 4 (a), and its width KL little by little enlarges.In addition, the shape of recess 46 is along with the central side that exists towards communicating pores 45 from bottom 44a, and recessed dark KW little by little reduces, and shown in Fig. 4 (b), final recess 46 assimilates with the scarp 42a of blade 42.So, the shape of recess 46 is along with towards central side, and width KL little by little enlarges, recessed dark KW little by little shoals, and cullet or foreign matter are discharged to become from groove 44 and be more prone to whereby.In addition, form recess 46 by laser processing, whereby, by the setting that utilizes laser spot or laser diffusion, can form the shape as above-mentioned recess 46 more simply.
In addition, in present embodiment, recess 46 only is arranged at blade front end 43 sides of the scarp 42a of blade 42, also can but arrange in the comprehensive scope of scarp 42a.If cross the part of butt glass and recess is set to be subjected to set state of loading when delineation, the effect of then discharging cullet or foreign matter will become higher.
Then, size about this scribe wheel 40 is described.Scribe wheel 40 D outer diameter m are 1.0-5.0mm, are preferably the scope of 1.0-3.0mm.D outer diameter m in scribe wheel 40 is little situation than 1.0mm, will reduce the processing of scribe wheel 40.On the other hand, be big situation in the D outer diameter m of scribe wheel 40 than 5.0mm, can't deeper form vertical crack to brittle substrate 17 when then having delineation.
In addition, scribe wheel 40 thickness T h are 0.4-1.2mm, are preferably the scope of 0.4-1.1mm.40 thickness T h are little situation than 0.4mm in scribe wheel, have processibility and the property handled reduction.On the other hand, 40 thickness T h are big situation than 1.2mm in scribe wheel, then the material of scribe wheel 40 and will uprise in order to the cost of making.
In addition, the blade nose angle θ 1 of blade 42 is generally the obtuse angle, and is 90≤θ 1≤160 (deg), is preferably the scope of 90≤θ 1≤140 (deg).In addition, the concrete angle of blade nose angle θ 1 can be done suitably by the material of cutting off brittle substrate 17, thickness etc. and set.
In addition, groove 44, gash depth H are the scope of about 0.5-20.0 μ m, and groove width L is the scope of about 2.0-50.0 μ m.And the front end that groove 44 is formed at blade 42 with the interval of 20.0-2000.0 μ m is week entirely.Gash depth is more shallow, and then cullet is easily blocked groove, because blocking of groove makes the delineation performance reduce easily, therefore, is the scribe wheel of 0.5-5.0 μ m in gash depth H in addition, the effect of recess is set especially for big.
So, in each scarp of scribe wheel 40 42a, be formed with the recess 46 that links to each other with the bottom 44a of groove 44, even the cullet that produces when disjunction brittle substrate 17 or foreign matter enter groove 44 whereby, also can not remain in groove 44 always, and discharge outside scribe wheel 40 by recess 46.Therefore, if use scribe wheel 40, can prevent because groove 44 remains cullet or foreign matter causes getting ready impacting and reduce or the deviation of crack depth causes disjunction bad.And, shown in Fig. 4 (b), recess 46 is for only cutting the part of the bottom 44a of the groove 44 that is made of width W, therefore about the function of grooves 44 such as the impregnability that improves crackle, 43 intrusions of restriction blade front end, is few by the influence that recess 46 causes is set.
(variation 1)
Variation to the recess 46 of the scarp 42a that is formed at blade 42 describes.In Fig. 5 of expression variation 1, shown the forward sight enlarged view of scribe wheel 40.The recess 47 of variation 1 in 2 scarp 42a that constitute blade 42, only is formed at a side scarp 42a.So, even only be formed with recess 47 in a side scarp 42a, entered cullet or the foreign matter of groove 44, also become by recess 47 and outside scribe wheel 40, discharged.
In addition because if only in a side scarp 42a form recess 47 also can, therefore compare with the situation that forms recess 47 in two sides' scarp 42a, shortened the manufacturing step of scribe wheel 40.
Further, owing to only be formed with recess 47 in a side scarp 42a, when delineation, be easy to make with respect to the face of the delineation line that forms substrate and stretch toward the oblique crackle of the inclination that is formed with recess 47 from vertical direction (normally vertical crack stretch direction), (when especially excising circular pocket) etc. has its effect when forming the delineation line of curve.
(variation 2)
In Fig. 6 of expression variation 2, shown the forward sight enlarged view of scribe wheel 40.The recess 48 of variation 2, in each adjacent grooves 44, conversion scarp 42a and forming alternatively.Therefore, recess 48 links to each other with the end of the folk prescription of bottom 44a.So, even conversion scarp 42a and be formed with recess 48 has alternatively entered cullet or the foreign matter of groove 44, also become by recess 48 by toward scribe wheel 40 outer discharges.
In addition, compare with the situation that forms recess 48 in two sides' scarp 42a respectively, can shorten the manufacturing step of scribe wheel 40, simultaneously as the whole quantity that reduces recess 48 of scribe wheel, the influence that forms in the delineation recess is diminished.
In addition, in present embodiment, as the method that forms groove 44 in the blade 42 of scribe wheel 40, illustrated about using discoideus grinding stone abrasive method, even but for example also can with the scribe wheel of other method formation grooves such as laser processing.Especially, form the situation of groove with laser processing, the shape of groove is close to V word shape, but V word shape groove compares with U word shape or rectangular-shaped groove, and the bottom of groove is for narrower, and cullet is easily blocked groove.But, by the recess that forms present embodiment, though groove be shaped as V word shape, the cullet that enters groove is discharged, prevent that groove from blocking, can prevent from delineating the reduction of performance whereby.
In addition, in present embodiment, as the formation method of recess 46, illustrated about being that the forward sight side of crest line is toward the method for the two ends irradiating laser of the bottom 44a of groove 44 from blade front end 43, even but beyond as this method, by the grinding of grinding stone and method that forms recess 46 etc. also can.
In addition, in present embodiment, recess 46 links to each other with the bottom 44a of groove 44, even but not necessarily link to each other with the bottom 44a of groove 44, and formation also can with the recess 46 that closely is close to as linking to each other of the bottom 44a of groove 44.
In addition, in present embodiment, recess 46 extends towards the central side of the existence of communicating pores 45, even but for example recess 46 shape of extending towards the sense of rotation of scribe wheel 40 also can.Even shape like this, cullet or foreign matter also are discharged from by recess 46.
In addition, in the delineation device 10 of present embodiment, the maintenance tool 24 that keeps scribe wheel 40 is installed on delineation 21 o'clock, becomes by keeping tool joint 23 that formation is installed.But, even delineation device 10 also can for directly keeping tool 24 to be installed on delineation 21 formation.
In addition, in present embodiment, as delineation device 10, represent to arrange usefulness so that delineate 21 guiding elements that move 22 or a bridge portion 19, or possessed the transfer table 11 of platform 16 rotations that make mounting brittle substrate 17, so do not delineated device 10 but be defined in.For example, the delineation 21 that keeps tool 24 is installed becomes by the user and grip in order to make, a part of shape of delineation 21 is become the shape of handle, control this handle and to move it to carry out as the disjunction of brittle substrate 17 the delineation device of so-called manual type also applicable by the user.
