Description
Technical field
The present invention relates to a kind of fixed-abrasive sawline that uses during the sawing hard brittle material.
Background technology
Current, sawing for example silicon, quartz, gallium arsenide, carborundum, sapphire, magnetic material or Cutting Length is by means of the single sawline of many rings less than the major technique of the hard brittle material of any other expensive material of to two meter.In this saw, by circular, thin, high tension steel wire, will comprise that the suspending fluid of the abrasive particle (being mainly carborundum) that is suspended in carrier liquid (normally carbowax) is pulled in the otch of workpiece.By forming ring parallel to each other with reeded capstan winch guide wire, thereby form wire screen.Roll extrusion-embeddeding action by the abrasive particle that rolls between metal wool and workpiece comes cut workpiece.Due to the change of slurry content during use, this process is thorny, due to all wearing and tearing and continued to replenish gradually of metal wool and abrasive material, it is expensive, because being splashed surrounding by capstan winch, slurries seem dirty and messy, and because the slurries (wherein having therein workpiece material fragment and steel sand) and the metal wool that use must abandon in a controlled manner, it has high Environmental costs.
Thereby this industry is sought method to exempt slurries preparation, slurries control and to abandon always.A kind of method of advising is to exempt the carrier liquid that uses abrasive particle, and abrasive particle directly is fixed on metal wool.So, only also need refrigerant fluid with cooling workpiece, and the chip that may be gathered on metal wool is cleaned.This causes:
Better sawing effect, because the whole momentum that has transmitted abrasive particle is with cut workpiece (no longer fine-grained rolling),
Purer side production, because refrigerant fluid mainly comprises workpiece debris, and
Use better the consumables, because use better abrasive material, and the wearing and tearing much less of metal wool (because abrasive material is fixed with respect to metal wool).
Such metal wool is called " fixed-abrasive sawline ".Abrasive particle is connected to the carrier metal line securely.Usually, use meticulous diamond particle (common 10 to 50 μ m sizes) as abrasive particle.This metal wool is kept its cutting action longer time because metal wool be not fixed on metal wool by grinding abrasion-abrasive material-opposite with loose abrasive material sawing processing, wherein metal wool also weares and teares, as the workpiece of positive sawing.
The sawline sawing causes the loss of (sometimes precious) workpiece material inherently.Thereby, also need ongoing effort to keep " kerf loss " (loss is as workpiece material amount of sawing chip) low as far as possible.The external external diameter of the fixed-abrasive sawline minimum of the current use minimum diameter of the imaginary circles of abrasive particle (that is, around) scope is being used for 310 μ m that blank and ingot be shaped between the 145 μ m that are used for section.
And in the sawline sawing, sawline must be strained.Along with sawline is pushed workpiece, convert the tension force that vertically applies in cutting planes transverse force.This transverse force-in conjunction with sawline vertically move-make the sawline cut workpiece.Thereby during sawing, it is arc that sawline is.Tension force is larger, bends littlely, cuts faster.In practice, tension force is about 25 newton in the section net, but in the situation that blank and ingot shaping larger (〉 70N).
When Free Abrasive cutting has the workpiece that geometric configuration renews-such as solar cell wafer-can drive sawline by uniaxially, namely during cutting, sawline moves on same direction all the time.Alternatively, for the lens parameters purposes-such as be used for semi-conductor industry-can drive this process two-wayly of requiring more.In this case, pull new sawline from bobbin at length FL forward on forward direction, sawing direction subsequently on length BL backward oppositely.FL is greater than BL." two-way sawing " is sometimes also referred to as " rear-front sawing ", " back and forth sawing " or " sawing of pilgrimage pattern ".At present, only be suitable for the fixed-abrasive sawline in the pilgrimage pattern, wherein length BL is slightly less than length FL forward backward.Thereby, repeatedly use same sawline length, namely have high Occupation coefficient.
This front and back sawing has some special problems.During backward directions, with the sawline wraparound that the scrap metal chip of workpiece (namely from) makes dirty of may being subjected to of using of sawing on clean sawline apart from BL.During this wraparound, tension force is in cutting head tension force, i.e. 25N or larger, and usually during producing sawline, the winding power of bobbin is only 2 to 5 newton.This may cause such as the sawline that will use " cutting " to enter problem in new sawline bundle, causes the fracture of sawline when detaching from new sawline in the sawline end that will use.Because sawline is coated with abrasive material, some abrasive particles can be used as the transverse cuts instrument of sawline, and in the situation that are subjected to the forces associated cutting of tension force and use or damage sawline.
During the high Occupation coefficient of sawline is hinting in each cycle and only considerably less sawline band to be networked, and before in entering net, its winding is back on new sawline repeatedly.For example, in the sawline of new length (FL-BL) enters net fully before-and no longer return to the unwrapping wire bobbin, it has been wound around BL/ (FL-BL) again on the unwrapping wire bobbin inferior.According to the pilgrimage pattern of using, this be easy to amount up on the unwrapping wire bobbin be wound around surpass 100, even 200 times.It should be noted that, for purposes of the present invention, to be called " unwrapping wire bobbin " (even it is temporarily as being wound around sawline, namely being wound around the bobbin of sawline) from the bobbin of upper consumption sawline, and the bobbin that receives the sawline that has used is called " take-up bobbin " (although it is used as the bobbin of sending sawline off and on).
And in the current machine design of major part, approximately 25 newton or the higher tension force that is used for sawing are passed to the coil of bobbin with having no to dwindle.More seriously, abrasive particle will be projected into outside the sawline surface (otherwise can not cut), and many be wound around backward during, on bobbin and arrive sawline back and forth damage each other on bobbin, this will be called as " from damage problem ".Owing to sawline being wound around back on the new sawline that still needs to use, this problem is the most serious in the unwrapping wire side.Thereby newly sawline enters in net with the state that has damaged, and has greatly increased thus the risk of sawline fracture during sawing is processed or has reduced the sawing performance.
By such as can prevent " certainly damage " problem in the machine design shown in EP0261695, US3942508 or US5052366, the sawline that described machine design will have been used is collected in the track adjusting wheel array system, and also reduced thus the sawline tension force from the cutting head to bobbin, but this design is more complicated and expensive.
In the take-up side, relatively so not serious from damage problem, because sawline wearing and tearing, and abrasive material rust: the sawline that enters the take-up bobbin drops on the sawline of experience wear.Thereby the sawline on the take-up bobbin can not be crossed poly-injury and fall within sawline on the take-up bobbin.Vice versa: the sawline that enters again cutting head on winding can not be positioned at the sawline on it and damage.
Searched and attempted addressing this problem, so that sawline is wrapped in layer on bobbin (described in EP1698433A1) with hexagon or square relationship carefully, so that anti-stop contact and propagate contact.Yet, provide the fineness of fixed-abrasive sawline, about 150 μ m usually, this is not easy.
Another solution of having advised is to use tack coat, and many abrasive material sawlines (US6178962) thereon in parallel with each other bond.
Current, the abrasive particle of diamond powder particulate is fixed on the carrier sawline so that incite somebody to action normally to have developed various technology:
Can realize fixing by mechanical bond: by diamond particle being pressed in bladder high tension sawline, such as, be for example described in the application of EP2010/055678 at the applicant's application number.In this sawline, the part of abrasive particle is arranged in bladder, has eliminated thus the outstanding of abrasive particle, and this is conducive to be avoided from damage.
Also considered metallurgical binding, for example by with particulate brazing or soldering on the surface of sawline, as for example described in WO99/46077.For such sawline, expection has for the fixing identical overhang of abrasive particle of machinery.
Also studied widely such as for example resin-bonded described in US6070570.Yet due to fixing very weak, this becomes and is difficult to particulate is fixed in resin during sawing.
By electrolysis or electroless plating ground fixed diamond particulate.The method derives from the discarded saw blade for the cutting silicon ingot, and also is used for frequently other diamond cut instrument.This abrasive particle is outstanding very many from sawline surface, makes it be subject to impact from damage problem.
Usually, can distinguish to some extent between the abrasive particle of the abrasive particle (resin-bonded) that organically combines and inorganic combination (in being embedded in metal level, brazing particulate, electrolysis or electroless plating plating particulate).
The inventor has found that the below will be described to this solution of problem scheme.
Summary of the invention
Purpose of the present invention is mainly to eliminate from damage problem.This purpose is especially carried out minimum possible change and is eliminated this problem process or machine.Groundwork of the present invention is to be easy to remove and disposable organic coating prevents that it is from damage by providing around the fixed-abrasive sawline.
Provide a kind of fixed-abrasive sawline according to first aspect present invention.The fixed-abrasive sawline is formed on the high tension component ambient usually, and it is mainly steel, such as the carbon element steel or stainless steel.The steel core of most preferably being made by carbon steel (minimum carbon content is 0.70wt% carbon) or corrosion-resistant steel.When being devoted to reduce the overall diameter of fixed-abrasive sawline, the tensile strength of sawline must corresponding increase.Preferred diameter and the tensile strength of the core of fixed-abrasive sawline are:
If diameter less than ... so tensile strength greater than ...
250μm 900N/mm
2
150μm 3600N/mm
2
140μm 3700N/mm
2
120μm 3900N/mm
2
Tensile strength is that the breaking load (newton) of sawline is divided by cross-sectional area (mm
2).
Abrasive particle is fixed on heart yearn.Abrasive particle can be super wear-resisting abrasive particulate, such as adamas (natural or artificial, the latter is slightly preferred, because its cost is lower and particle is frangible), cubic boron nitride or their compound.For more undemanding application, can use such as carbonized tungsten (WC), carborundum (SiC), aluminium oxide (Al
2O
3) or silicon nitride (Si
3N
4) particulate: although they are softer, compare with adamas, they are quite cheap.Yet, the most preferred adamas that remains.
By means of being that inorganic bound layer is connected or fixed to heart yearn securely with abrasive particle.Term " inorganic " refers to and does not rely on carbon or chemistry of silicones with the fixing bound layer of any type of particulate.Use resin with the fixed-abrasive sawline that abrasive particle is fixed to heart yearn in, bound layer is inorganic.
The example of inorganic bound layer is:
By in the soft formation that abrasive particle is embedded the encirclement heart yearn, subsequently by fixing that the metallic coating described in WO2010/125083 and WO2010/092151 forms.Preferably, the first soft formation is the copper layer, and coating is nickel.
By fixing that the welding described in WO2010/071198 forms.Preferably, the scolder that uses is the watery fusion scolder, such as Xi Yin or Welding Sn-Zn material, with the thermal load of restriction heart yearn.Alternatively, can use high temperature resistant line, the tungsten line described in US6102024.Clearly that this metal level is inorganic layer.
Process by electroless plating or electrolytic deposition form fixing.Inorganic coating is metallic coating, most preferably the nickel metallic coating.An example of preferred fixed-abrasive sawline has been described in US7704127 or EP2277660.
Form fixingly by other inorganic means, such as for example, be embedded in glass coating.
From the above clear as can be known, preferably, inorganic bound layer is actually metal, wherein uses different layers to be used to realize different functions.Soft for the preferred metal of embeding layer, such as zinc, copper, brass, dead-soft steel, if be used for master metal nickel or the nickel alloy (nickel phosphate, nickel cobalt etc.) of fixed-abrasive particulate.
Most preferably the fixed-abrasive layer of electrolytic deposition, because adamantine projection has caused high cutting efficiency basically.Yet, this high-caliber outstanding high risk damage certainly that caused, it can be solved as described below.
Should have the fixed-abrasive sawline of attached abrasive particle thereon in inorganic coating, also cover organic coating.Organic coating is not intended abrasive particle fixing in place.This organic coating intention protection fixed-abrasive sawline prevents from damage.Because organic layer before using is positioned on sawline, but disappear after using, the metal wool that uses that winding is back on new metal wool will can not be subjected to the damage of new sawline, because this used metal wool is positioned on " pad " that the organic coating by new metal wool forms.On the contrary, be positioned on bobbin new metal wool by organic coating protection prevent from being subject to high tension be located thereon substantially without the infringement of using metal wool of organic coating.
Because the function of organic coating is only used for during transportation protecting sawline, its sawing function for sawline is utterly useless, and can not hinder this function.For purposes of the present invention, " transportation sawline " should broadly be thought, not only mean integrally physical transportation sawline circle, mean that also the sawline that namely is wound around or winds off is also thought " transportation " sawline if only be transported to a part of sawline on carrier or leave carrier.Thereby the radical function of organic coating is " preventing that during transportation sawline is from damage ".Because organic coating has high self-friction coefficient basically, another advantage of organic coating is that the different coils of keeping in bobbin are fixing relative to each other.Like this, prevented In transit or pass the sawline net during tangling between sawline.Thereby, organic coating stickiness, astringency is preferably arranged.The advantage of this coating is to have prevented sawline transverse shifting relative to each other: be accurately the axle that the abrasive particle scratch favours this sawline, this is the most harmful for sawline, and it is for good and all ruptured.
In order to make organic coating not hinder the sawing process, some select still to keep opening:
At first, can only remove organic coating before using the fixed-abrasive sawline.In this case, should provide the removing method step between unwrapping wire bobbin or unwrapping wire bobbin and sawline net, it moves into the organic coating on its first entrance in net.Thereby in each circulation, BL removes in last circulation due to its residue length, needs only to discharge from organic coating length (FL-BL).
Certainly, selection is extremely important for the organic material of organic coating.Coating should be cheap, easily use, soft, non-adhesion or the utmost point adhere to metal minutely and most important be to be easy to remove, and preferably this is in eco-friendly mode.
Thereby, be most preferably the weak non-metal adherent coating of mechanicalness, it can be dissolved in polarizable medium.The example of polarizable medium is: water, carbowax, ethanol, diethylene glycol, or their compound.These are also the liquid with the basis of the cooling system conditioner that acts on the fixed-abrasive sawline.
The poly-mer that particularly preferably can be used as organic coating is polyvinylpyrrolidone, polyvinyl acetate, poly-(acrylic acid), poly-(methyl acrylate), methylcellulose, polyvinyl alcohol or ethylene/vinyl alcohol copolymer, Ju Yi Xi oxazoline or its compound, because they easily are dissolved in polarizable medium as above.Most preferably polyvinyl alcohol and methylcellulose.Polyvinyl alcohol is easy to be dissolved in water, and has remarkable film shaped ability, and nontoxic.Methylcellulose forms precipitation in polarizable medium when medium is heated, this provides the facilitated method that removes it.
Biopolymer is also good selection, because their biodegradables, and mechanicalness is not very strong basically, and some of them are easy to be dissolved in water.Significant example is: casein, starch derivative, Aquagel, glycan or albumen based polyalcohol.
Alternative poly-mer is the poly-mer that is insoluble in polarizable medium, such as thermoplastic polymer, hot-melt polymer or thermosetting polymer.Although be not impossible in essence, for desired use, they are more not preferred.
The amount of the organic coating on the fixed-abrasive sawline can not be many.It must be enough to cover adamas, and prevents that sawline from sliding on each other.It is enough to make comprise described organic coating at the minimum periphery circle diameter of interior described fixed-abrasive sawline greater than only around the minimum periphery circle diameter of described abrasive particle.Too much coating will form too much refuse (in apparatus for removing or in refrigerant fluid).The coating deficiency will can not be brought the advantageous effects of protection fixed-abrasive sawline.
The alternative approach of determining amount of polymers is to decompose by carbon high-temp to determine the lip-deep organic carbon residual content of sawline.Only need limited sample (1 to 2 gram) herein.Sample is heated to 480 ℃, until the organic remains on sample (but not the carbon in steel) resolves into carbonic oxide and carbon dioxide.In the catalyst of 850 ℃, all carbonic oxides convert carbon dioxide to.Calculate the total amount of carbon according to the infrared absorption of carbon dioxide.It is remaining that remaining carbon total amount must contain 400 μ g carbon greater than every gram sawline at least.It should be not more than every gram sawline and contain 5mg carbon remnants.Because the poly-mer of organic coating not only comprises carbon (also comprising hydrogen and oxygen), numerical value is determined less than other method such as double weighing.
According to a second aspect of the invention, required a kind of method of during transportation protecting the fixed-abrasive sawline.The method comprises the steps:
The fixed-abrasive sawline is provided, and abrasive particle thereon is fixed in inorganic coating;
Apply the fixed-abrasive sawline with removable coating before using or during using sawline.
Randomly, the fixed-abrasive sawline of coating is collected on carrier such as bobbin, packs and is transferred to sawing machine.
Carry out the other method step on sawing machine, wherein:
Before using the fixed-abrasive sawline or remove organic coating between used life.
Can apply in every way sawline: can apply by mold pressing, powder coated, powder static electricity coating, heavy curtain coating, brush, dipping or their combination.These methods are well known by persons skilled in the art.Extruding can be passed through extrusion head, but also can be very basic, by comprising the tank of poly-mer, peels off excess stock by guiding fixed-abrasive sawline subsequently in (diameter is justified greater than minimum periphery) rubber pattern." heavy curtain coating " is that the guiding sawline is by the method for the poly-mer of the pure of laminar flow heavy curtain or dissolving.Electrostatic coating is very complex.
Can use these methods during producing sawline, but other more effective possibility is also arranged on single sawline.Can be for example to apply the fixed-abrasive sawline when being wrapped in the carrier of bobbin for example or reel along with the fixed-abrasive sawline: can all apply this coating to every layer of being formed on reel, the spitting image of for example carrying out mopping by means of brush.Like this, all sawlines all apply well, and have enough protections between coil.Alternatively, by oppressing poly-mer by the sawline bag and air pump being gone out outside the core of bobbin, can use polymeric coating to clamp-on carrier in the lateral.Like this, during transportation protected preferably the fixed-abrasive sawline.
For the possible method that removes organic coating be:
For example brush organic coating by means of spiral brush sifter, sawline passes described spiral brush sifter.Can use solvent streams cleaning brush constantly, so that make it there is no chip;
By peeling off, for example by the sawline that at first rolls against roller, thereby the coating breach is torn voluntarily.Another method for optimizing of peeling off is that organic coating is for himself being also stickiness, and is still less for the stickiness of sawline.During being wound around, the organic coating of different windings is with bonded to one another.When unwinding, organic layer will preferably be kept and be connected to other organic layer, and the coating that will tear sawline.Subsequently, organic coating is retained on bobbin, and must remove on bobbin.
By the polishing by the ring rotation brush.
By peelling off coating, for example, by guiding it by narrow coupling crack.By making sawline pass through sheeting when the machine startup, can easily form this crack, preferred sheeting is the material with sawing.In case formed this crack, can begin cut workpiece.
By heating or burning coating.
Dissolve coating by solvent tank, this solvent removal coating by the guiding sawline.
Certainly it is also conceivable that the combination in any of said method.
The second, organic coating can be so that coating be dissolved in the refrigerant fluid that uses in the sawing process.Need not to carry out any machine during its attendant advantages revises.Along with organic coating gathers, needs are worked out measures to remove organic coating from cooling system conditioner in cooling system conditioner.
The 3rd, can consider that combination " before using " and " between used life " remove the combination of organic coating.Because 100% formerly cleaning will particularly be difficult to realize, will remove some remaining organic coatings during sawing.
