Laser just is born to be called by people before long " the tool that solves a problem " . Scientists realize laser at the beginning this kind of queer thing, will want to become the technical factor with this the mainest times. Up to now, mere tens of year initial application, laser had produced major effect to our lifestyle. Laser hits mark technology laser to make mark technology is one of applied fields with the biggest laser beam machining. Laser makes bid is to use the laser of high energy density to undertake local illuminate to workpiece, make vaporization of surface layer material or the chemistry that produce color change react, leave a kind of of permanent mark means that make bid thereby. Laser hits mark to be able to hit all sorts of characters, symbol and design to wait, character size can measure level to micron from millimeter, of this pair of products prevent bogus to have special sense. Be in plastic on the extremely fine laser light beam after hitting mark to hit mark focusing on the metal as cutting tool, but purify of pointwise of object surface material, its are advanced the gender depends on labelling Cheng Weifei contacts a gender to machine, do not produce mechanical extruding or mechanical stress, because this won't damage,be machined article; Because the size after laser focusing is very small, hot influence area is small, treatment is careful, accordingly, can finish the technology that a few groovy methods cannot implement. Laser beam machining uses " cutting tool " the spot that is focusing hind, do not need additional add other equipment and material, want laser to be able to work normally only, can machine for long continuously. Rate of laser beam machining is rapid, cost is low. Laser beam machining by computer automation, factitious intervention does not require when production. Stimulate light energy mark why to be planted information, only the content with the design in the computer is relevant, the graph draft that should design in the computer only hits sign system to be able to identify, so the machine that make bid is OK will design information accurate reductive go up in appropriate carrier. Because the function of this software decided systematic function greatly actually. Technology of Laser Cutting of Laser Cutting technology applies extensively in the treatment of metal and metalloid material, can reduce handling time greatly, reduce finished cost, improve workpiece quality. Contemporary laser became people place to imagine pursuit " cut iron to be like mud " " sword " . Cut of armor plate of organic glass cut is with machine of my company CO2Laser Cutting exemple, whole system is mixed by control system, campaign system, optical system, water-cooling system, smoke evacuation the composition such as the protection system that blow air, use the most advanced numerical control mode to realize much axis linkage and laser not to suffer what speed affects to wait for energy cut, support the graphical form such as DXP, PLT, CNC at the same time and scale of aggrandizement interface graph handles ability; Use the entrance servo electric machinery with superior performance and drive to direct the structure realizes good below high speed condition motion precision. The energy of high power density of the generation after applying laser focusing will realize Laser Cutting. Below the control of the computer, make through pulse laser discharges, output controlled repetition thereby high-frequency pulse laser, form certain frequency, the beam of light with constant wide pulse, beam of light of swash of this arteries and veins conducts what reach reflection and machining an object through focusing of focusing lens group through smooth road apparently, form each subtle, facula of high energy density, jiao Ban is located in need treatment near the face, with the instant high temperature fuses or aerification is machined material. The laser pulse instant of each high energy splashs object surface shoot a petty hole, in the computer control falls, head of laser beam machining and be pressed by treatment material beforehand the figure with good draw undertakes athletic relatively continuously getting ready, can machine the object into wanted form so. When cut, an as coaxial as beam of light air current by cut head ejective, will fused or the material of aerification blows by the bottom of cut (note: The gas that if blow,gives and be arisen to heat up effect to react by cut material, criterion the additional energy resources that this reaction will offer cut place to need; Air current still has refrigeration already cut face, reduce heat to affect area and the action) that make sure focusing lens does not get pollution. With traditional plank treatment method photograph is compared, its have Laser Cutting high cut quality (cut width is narrow, hot influence area small, cut is bright and clean) , high cut rate, tall flexible (but appearance of optional cut random) , the advantage such as extensive material adaptability. Laser beam welding receives technical laser beam welding to receive one of important facets that are application of laser material processing technique, solder the process belongs to heat to conduct model, stimulate ray radiation to heat namely workpiece surface, exterior quantity of heat conducts inward ministry to diffuse through heat, power of the width that passes control laser pulse, energy, peak and repeat the parameter such as frequency, make workpiece fused, form specific bath. As a result of its distinct advantage, in applying Yu Wei, small-sized spare parts successfully to solder. High power CO2 reachs the occurrence of laser of high power YAG, open up the new field that laser beam welding receives. Obtained the deep frit that is theoretical foundation with keyhole effect to receive, increasingly wide application was won in the industrial department such as mechanical, car, iron and steel. Thin wall of mobile phone batteries solders stainless steel solders with other the technology is compared, the main good point that laser beam welding receives is: Laser beam welding receives rate fast, deepness is big, be out of shape small. Can undertake soldering below room temperature or special condition, solder equipment unit is simple. For example, laser traverses electromagnetism field, beam of light won't deflection; Laser all can apply solder in air and some kind of gas atmosphere, can pass glass or undertake soldering to the material with transparent beam of light. After laser focusing, power density is high, when high power parts of an apparatus solders, deep wide Bikeda 5: 1, highest can amount to 10: 1. Can solder difficult frit material is like titanium, quartz to wait, can apply solder to opposite sex material, the result is favorable. Be like, copper and Tantalum the material with two kinds of disparate property solders together, percent of pass is amounted to almost 100 percent. Also can undertake miniature solders. Very small facula can be obtained after stimulating focusing of classics of beam of light, and can exact location, in the group solder of the small, small-sized component that applicable produces at big batch automation, for example, electron gun of integrated circuit down-lead, horological hairspring, picture tube is assembled because used laser beam welding,wait, manufacture efficiency not only big, tall, and hot influence area is small, solder nods free from contamination, improved soldering quality greatly. The place that can solder to be close to hard, applying blame contact is remote solder, have very big flexibility. Fiber-optic transmission technology is used in YAG laser technology, make laser beam welding received a technology to win more extensive promotion and application. Stimulate beam of light of easy implementation of beam of light to press time and space prismatic, can undertake much beam of light is machined at the same time reach multitask treatment, for more accurate solder offerred a condition.
