Current, taller and taller to the quality requirement of glasswork, processing technique besides the material character that should consider to differ, still must come true more accurate, meticulous with net treatment result, and the standard that the Laser Cutting technology of innovation has made a lot of industry glass cut. The market that demand increases increasingly waits in the electron, the innovation technology of cut of urgent need glass. Traditional vitreous cut method uses hard alloy or diamond cutting tool, be used at a lot of application widely in the center, cent of its cut flow is two measure. Above all glass is used diamond point of a knife or hard alloy emery wheel, a crackle arises in vitreous surface; Later, the 2nd pace uses rigid step to break up glass along crackle line namely. However, use this method to undertake cut is existing delimiting engraving mixing a few blemish. The purify of material can bring about the generation of drossy, shiver and small crack, make the intensity of cut brim is reduced, need to undertake clearing together again thereby working procedure. From this the deep crackle that craft brings normally won't perpendicular at vitreous surface, the cent secant that the reason depends on mechanical power place generating is general dispute is perpendicular. And, the crop loss that mechanical power effect brings at thin glass also is a negative factor. These blemish can pass above use stress-free glass and optimize further use at intersected tool to get ameliorative. However, mix to perpendicular cut line prevent the brim drossy / for the systematization contradiction between crackle, want to avoid completely still impossible. The development of laser technology brings knowledge for these quality problems definitely plan. Laser is underlined and break up the mechanical cut tool with the tradition to differ, the energy that stimulates beam of light is not osculatory means to have cut to glass with a kind. This energy undertakes heating partly to the designation of workpiece, make its reach the temperature of predefine. Back-to-back move undertakes fast refrigeration after this process that heats quickly, make vitreous interior generation perpendicular to stress belt, appear in this direction one is not had drossy or the break of crackle (see a picture 1) . Because break arises because of be heated only, machinery of and rather than arises consequently formerly, won't have so drossy appear with micro-crack. Accordingly, the intensity of Laser Cutting brim delimits with the tradition engrave and breaking up means photograph to compare is to want stronger. The need of finish machining also gets reduce or needing far from. Additional, to appearing the state of vitreous shiver also can avoid completely. Delimit to laser quarter for, heat in what stimulate beam of light reach subsequently cooling process (see a picture 2) below action, vitreous surface by lay off a deepness is 100m about (the agreement of vitreous ply 10% ) . Glass subsequently can along delimit the direction of quarter is come to by cent rift. Because this technology does not produce any vitreous shiver, the Mao Bian with cut common brim and low intensity also got avoiding, the working procedure of follow-up polish and burnish also needed no longer. More important is, for glass of intersected of relatively traditional method, via the glass that this method machines its are able to bear or endure broken degree be as high as 3 times. Come in 50m to ply the glass between 1mm, even if the cut that finishs whole with one pace only also is likely (see a picture 3) . Break up and follow-up polish, burnish, rinse wait for measure to need no longer. The intensity of cut edge can pass the standardization that comes from DIN-EN 843-1 to curved a test to get metrical at 4 o'clock. A glass is secured to be on two gyro wheel (see a picture 4) , on glass the surface is passed additional two gyro wheel are used to the power folding a turn that generation needs, below this active force glass can be broken up to be two parts. This test is repeated about 100 times, get the appropriate reliable statistic about breaking up possibility is worth thereby (see a picture 5) . Below most circumstance, laser is underlined and cut is large quantities of choices that measure treatment. Its advantage depends on very high treatment rate, high accuracy, and simple parameter setting. However, in cut the circumstance with a lot of diverse line and enough handling time falls, integral cut is a kind of more charming method, because its have kind of dry type refrigeration and not additional cut measure. The cut margin of high quality generates in the metropolis below these two kinds of circumstances. If use Laser Cutting glass,see, can saving time completely while, bring those who machine quality to rise. The Laser Cutting in production brand-new and mature technical transplanting arrives in big batch product line, use at machining high-tech product to be not easy thing. For the angle from the client, before carry out, this technology must be an automation, credible solution, got sufficient proof not only, and considered economy. In be being operated actually, the application of innovation technology falls in two kinds of circumstances only effective: Of new product roll out need to new manufacturing measure will achieve innovation trait or reduce manufacturing cost through reducing treatment measure, existing perhaps production encounters economic pressure to need tremendous producer type to reform will alleviate. In flat video industry, the promotion of Laser Cutting technology cost lustrum to just find his place in product line, premise was to experience thousands of hours to apply test and verify in a lot of treatment on-line. Normally the consideration is used at the production of the new product with existence broken and dangerous glass now, perhaps use those who taste at be being produced of communication shift of glass to make in electronic industry, other perhaps existence includes thin glass the product of brittle component, like sensor, touch accuse board or vitreous case. Treatment undertakes in clean room normally, industry of biochemistry of no less than is same, the particle that because these are,arises to traditional cut or grinding measure is very sensitive. For example, enclothed DNA code (biochemical bar code) base material or be become by Laser Cutting piece material is used at product test. To Laser Cutting technology, the next has potential application industry most will be solar energy industry and automobile industry. The development situation that technology of laser of no less than comes to for years in metallic treatment industry is same, with the Laser Cutting that machines at glass the technology also will continue to develop; This technology will be applied extensively in the treatment of different product, replace traditional method. However, traditional glass machines a method to still will maintain its to machine medium significant position in most glasswork henceforth, be opposite in these application generally speaking the treatment quality demand of cut brim is very not high. Laser appearance cut is an innovation technology, position will be found in electron, car or construction industry. Besides Laser Cutting glass, still have other the method of glass of a lot of laser beam machining is mixed at further development experiment phase, like bore, pour wine cup, and coating purify. The laser with these craft different and phyletic requirements, be like green laser. Already mature CO2Laser Cutting technology is used in treatment other and brittle material, if produce electronic industry any crystalline substance yuan material of pottery and porcelain. The material with other semiconductor common industry also hopeful is become by the object of laser beam machining, its can pass a test and should throw actual production only in the center.
