To the treatment of substrate of pottery and porcelain

Laser technology is applied extensively in electronic industry to machine alumina and nitrogen to change substrate of aluminous pottery and porcelain, heretofore has 30 old histories. To be cent of substrate of pottery and porcelain independent part, can use laser score (dozen auger) a series of local (did not connect) hole of tall public errand. These hole about thorough substrate 1/3, generate later period cracked preferential fault line. Use other technology, also can machine appearance of aperture of access, chamfer, affirmatory form and careful design on substrate. Because commonly used pottery and porcelain has absorption character, CO2 laser has made the choice of laser. The energy of light beam of pulse CO2 laser is absorbed in surface of pottery and porcelain, because this arises local heating, fused with vaporization. Show an alumina inside 0.

0045 inches of lineation top view, make clear using relatively longer during pulse (about 75-300m, inspect ply and decide) , under the low energy brim in distributinging plan of energy of gauss beam of light, because of local and fused the heat that cause affects area (HAZ) . Old since, CO2 laser with long when the number works, in gas and energy the respect will drain a large number of resource, still ask to make defend a plan. Additional, the model means sealed canal with the pulse parameter that applies at this kind CO2 laser technology is not quite proper. For whole, when a large number of the course is old improvement, CO2 laser is mixed in dependability after safeguarding problem respect to still be located in other technology. During safeguard, the quality of beam of light of these laser still changes easily; The size of the smallest spot that can reach also is affected easily by the long wave. Will tell alone, the laser light beam of pottery and porcelain absorbs character to make this kind of technology affects a long time of this market territory. New underline a technology to try before Nd:YAG laser applies at underlining did not succeed in craft, because of 1.

The absorption of M of 064 μ is too weak; The result of need produces in exterior layer without enough energy deposit. For this, company of Synchron Laser Service (be located in the United States close hold the South Lyon that bring a city) developed finishing technology, strengthen pottery and porcelain in order to be inside shorter wavelengh limits to be opposite of laser beam absorb. This kind of technology is fast and slightly surface of immerge pottery and porcelain is in enough the deposit energy that short distance strengthens pulse of close infra-red laser, fuse necessarily in order to arise and vaporization. Plant this mixing in the finishing technology of patent application SPI Lasers (be located in British Southampton) combination of photograph of fiber-optic laser technology, the technical properties that shows actually is head and shoulders above the technical properties that use CO2 laser can achieve. Finishing strengthened fiber-optic laser light beam to blend in surface of coping of pottery and porcelain greatly in, get a course with beginning to hit. Between laser pulse and material surface of interaction enhance power, the beam of light of custom-built high resolution that was united in wedlock to ensure exterior spot volume agrees continuously transfers a system, this is meant smaller form appearance can achieve in substrate of pottery and porcelain now. Synchron also considered technology of laser of a few existing other, the hope can machine more careful even lineation; But conclusion is: Without a kind of technology can with its unique kind achieves target rate, want at least below a few circumstances 10 times slower. Compare with CO2 laser, fiber-optic laser reveals a much better consistency and dependability, can machine more careful form appearance, after including burst, brim quality raises 3 times above. Showed the brim mass that can reach further, the former brim that describes generation of cut arrowhead appearance here. Important is, new technology can achieve the manufacturing rate that when using CO2 laser, cannot achieve even. Nextpage is in 0.

On 0150 inches of thick alumina substrate, underline speed minutely now more than 1300 inches, be CO2 laser about double (thorough 30% ) ; But machine treatment speed is average at least, below most circumstance speed exceeds CO2 laser. According to the circumstance of Synchron, because use shift to control laser of systematic and rather than,be, just bring about crop to suffer be restricted. The means that can use this kind of stylish machines alumina and nitrogen to change aluminous pottery and porcelain. When using alumina, craft limitation arrives at be being amounted to at most about 0.

060 inches substrate ply, in although be in,needing more for long to machine conditional severe exacting to apply thicker material. Thicker substrate also can offer more to come loose hot, use medium case to tall brightness LED for example. Nitrogen changes aluminous pottery and porcelain to be machined harder than alumina commonly, because hot conductibility is better, because this machines a requirement,have proportionate more high-power. On the other hand, can achieve more careful form appearance, because have the highest density share of beam of light only,ability can produce the technology of need, and the rate of minimum of tall thermal conductivity of material dropped distributinging plan of energy of beam of light the HAZ of two side. The preliminary result that uses this kind of new method is admirable, the technology that uses this kind of data is OK still fine tuning. Craft improves fiber-optic laser to be able to provide a series of distinctive performance, apply at comprehensive material treatment. For example, reliable gauss beam of light distributings graph (TEM00) the spot volume that agrees continuously to the surface is achieved and be being safeguarded is very main. Fiber-optic laser is behaved on one hand in this good, all output power reveals a particularly high grade beam of light to distributing, because this permits the work the space is large (independent) . Another kind of advantage is small spot dimension and changeover of high grade beam of light the tall brightness that is a focus is smooth, realize reliable treatment, definition is high, HAZ is the smallest. Fiber-optic laser can pass what the following kinds of means achieve the oldest rate jointly to reduce operation cost: Reduce safeguard cost, requirement, longer without alignment or calibration normal run time and manufacturing quality improves when higher yield. Fiber-optic laser structure is compact, strong and durable, because this suits,provide the industrial environment of the challenge most. The new field that the in only the technology broke through industry technology of Synchron progresses, cannot match the treatment of other material in consuming electronic product to produce namely. Industry tycoon is opposite less, compete on one hand cost is high, still need to carry quick change to client demand on the other hand, face this kind of condition, any technology progress are brought about possibly gain main market. Combine fiber-optic laser and the form appearance measure that only the surface revises craft to come true to reduce, machine for pottery and porcelain of electronic product class more careful underline open gate, every months of crop exceeds 10 million normally, the production of the product of massive spending electron of phone of type of comfortable contented a honeycomb-like thing and musical player and the high density LED that are used at be in a poor light to apply with the car needs. In fact, a few industry are asking ＜ of hole of substrate of pottery and porcelain 0.

003 inches, accuracy excel 0.

0005 inches, use CO2 laser to reach this kind of resolution not easily, but the new method of Synchron has reached this kind of level in mass production. Finishing can use spray, immerge or roller is pressed, do not need many drying time. Finishing of applied pottery and porcelain won't add other technology measure, the besmear cloth measure because of a few types (it is to prevent normally splatter layer) commonner to the CO2 treatment technology that has built. Additional, the odd-come-short active that new technology produces is lower, the amount is fewer, can eliminate only splatter problem. Machine the form appearance with more careful substrate of pottery and porcelain with higher rate, the advantage was brought for electronic industry in design, function and cost respect. Fiber-optic laser can achieve better balance in the important level that the help asks in feasible competition: It is flexibility of effective and optical function, craft, high yield, long normally the system moves normally and dependability. To the circumstance of Synchron, fiber-optic laser conduces to ensure achieve the pottery and porcelain that cannot come true before to machine performance level. CNC Milling
