At present technology of mature already laser beam machining includes: Laser becomes form technology, laser beam welding to receive technology, laser stiletto technology, Laser Cutting technology, laser to hit mark technology, laser to balance technology, laser to etch again quickly technology of technology, laser fine tuning, laser storage technology, laser is underlined technology, laser cleans a technology. Laser is fast figuration technology is compositive the newest achievement of laser technology, CAD/CAM technology and material technology, according to the CAD model of the spare parts, with stimulate beam of light to chase photosensitive group data a solidify, accurate accumulation becomes kind, do not need mould and cutting tool to be able to make the part with complex form accurately quickly, this technology already got applied extensively in the industrial domain such as aerospace, electron, car. Laser beam welding receives a technology to have dissolve pool to purify effect, metal of can pure welding line, apply to identical with different metal stuff between solder. Laser beam welding receives energy density tall, rate of dot, tall to Gao Rong reflectivity, tall heat conduction and physical character differ very big metal solders particularly advantageous. Laser stiletto technology has precision tall, versatility strong, efficiency tall, cost is low show the advantage such as the move with integrated technology economic benefits, already made one of crucial technologies of contemporary production domain. Laser Cutting technology can apply extensively in the treatment of metal and metalloid material, can reduce handling time greatly, reduce finished cost, improve workpiece quality. Pulse laser applies to metallic stuff, successive laser applies to metalloid material, latter is the fundamental application domain of Laser Cutting technology. Laser makes 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 quantity, of this pair of products prevent bogus to have special sense. Allowing molecular laser to make bid is a when in recent years development rises new technology, special apply to a metal to make bid, can come true inferior micron makes bid, use extensively already at microelectronics industry and biology project. Laser goes balancing a technology again is to use high speed of laser take out to rotate the lopsided overweight part on the component, make inertial axis and coincide of runner shaft coming back, in order to obtain the process of dynamic balancing. Laser goes balancing a technology to have again measure and go weighing two big functions, can undertake lopsided measurement is mixed at the same time corrective, efficiency rises greatly, in top production domain has wide applied perspective. To high accuracy rotor, laser dynamic balancing but twice raises balance precision, the balance precision of prejudicial value can amount to its quality 1% or thousand micron. Laser etchs the technology etchs than traditional chemistry technical craft is simple, can reduce manufacturing cost substantially, can machine 0.

The line with 1 broad micron of 125 ～ , special agree with the production of VLSI. Technology of laser fine tuning can undertake automatic and accurate fine tuning to appointing resistor, precision can be amounted to 0.

01% ～ 0.

002% , taller than the precision of conventional treatment method and efficiency, cost is low. Laser fine tuning includes filmy resistance (0.

01 ～ 0.

6 micron are thick) with thick film resistor (50 micron of 20 ～ are thick) the fine tuning, fine tuning of capacitance and the fine tuning of mixture integrated circuit. Laser storage technology is to use laser to record a kind of technology of data of video, frequency, character and computer message, it is one of technologies propping up of informatization times. Laser underlines a technology is the crucial technology that produces integrated circuit, its underline fine, precision tall (the line is broad for 15 ～ 25 micron, groove deeply 200 micron of 5 ～ ) , treatment rate is rapid (can amount to 200 millimeter / second) , n can be amounted to 99.

5% above. Laser cleans technical adoption to be able to reduce the atomic pollution that machines parts of an apparatus greatly, raise the n of rigid parts of an apparatus. Laser heat, watch handles a technology to include: Laser photograph becomes sclerotic alloy of surface of technology of technology, laser bag Fu, laser changes technology of anneal of technology, laser, laser to pound aggrandizement of sclerotic technology, laser to eletroplate technology, laser glaze technology, the mechanical function to changing material, hear resistance mixes these technologies corrosion resistance have main effect. Laser photograph becomes sclerotic (namely laser quenchs) it is the research in laser heat treatment the earliest, most, progress a the fastest, application is the widest kind of new technology, apply to the different position of most material and different figure spare parts, can increase the wearability of the spare parts and fatigue strength, a few industry departments of foreign regard the method that assures product quality as this technology. Technology of laser bag Fu is one of technologies of laser surface modified that acquire wide application in industry, have very good economy, can increase the corrosion resistance of the product greatly. Laser surface alloy changes a technology is the new method that local modified handles material appearance, it is one of exterior modified skills with prospective application the greatest potential, improvement of the need in applying to manufacturing industry of industry of aviation, spaceflight, enginery, nucleus, automobile is wear-resisting, anti-corrosive, high temperature resistant the spare parts that waits for function. Laser anneal technology is a kind of when semiconductor machines new technology, the effect is better than groovy hot anneal much. After laser anneal, of foreign matter replace a rate to be able to achieve 98% ～ 99% , can make the resistor rate of polycrystalline silicon falls common heat the 1/2 ～ 1/3 of anneal, what still can raise integrated circuit greatly is compositive degree, make the interval between circuit element narrows 0.

5 micron. Laser pounds sclerotic technology to be able to improve the mechanical performance of metallic stuff, the generation that can prevent crackle and patulous, raise the intensity of the alloy such as steel, aluminous, titanium and hardness, improve its fatigue resistance can. Laser aggrandizement eletroplates the deposition rate that the technology can raise a metal, rate is 1000 times rapidder than having laser illuminate, the production of parts of an apparatus of spare parts of switch, accurate to miniature instrument, microelectronics and circuit of large scale integration and repair have idea of heavy cardinal principles of righteousness. Use the firmness that changes a technology to be able to make report spends a layer to rise hold 100 ～ high 1000 times. Laser glaze technology has development outlook very much to material modified, its cost is low, be controlled easily and duplicate, be helpful for developing new material. The technology such as spray of flame spraying of laser glaze union, plasma, ionic deposit, organize in control, increase exterior wear-resisting, corrosion resistance can the respect is having wide applied perspective. Electronic material, electromagnetism material and other are used at measuring meter after glaze of laser of electric material classics very ideal. CNC Milling
