The wide application of laser beam machining

200 million dollar, grow 14 ％ than 1996, among them material treatment is 8.

2.9 billion dollar, medical treatment uses 300 million dollar, research a field 1.

500 million dollar. Gross income predicted to grow 19 ％ 1998, can achieve 38.

200 million dollar. Occupy the first material treatment to predict to exceed 1 billion dollar among them, medical laser is the 2nd big application of foreign. In domain of application of laser beam machining, CO2 laser is used with cut and solder reinforce the widest, occupy respectively 70 ％ and 20 ％ , finishing is less than 10 ％ . And the application of YAG laser is in order to solder, mark (50 ％ ) with cut (15 ％ ) give priority to. 70~80 ％ was occupied in the United States and European CO2 laser. 10 ％ are occupied with what cut gives priority to in our country laser beam machining, among them the CO2 laser of 98 ％ above, power is in 1.

Inside 5kW~2kW limits, and the agreement that gives priority to with heat treatment occupies 15 ％ , great majority is the steam cylinder bushing that undertakes laser handles car engine. The economy of this technology and social benefit are very tall, reason has very big market perspective. In auto industry, technology of laser beam machining developed his adequately advanced, fast, neatly treatment characteristic. If be in car prototype and small lot production,use machine of three-dimensional Laser Cutting in great quantities, saved example and tool equipment not only, still shortened greatly manufacturing preparation is periodic; Stimulate beam of light to be mixed in tall hardness material complex and bent surface spile, rate is rapid and do not produce damaged; Laser solders to already made standard technology in auto industry, japanese Toyota already soldered what laser uses at automobile body face plate, the plate of will different ply and different face coating solders together, undertake punch again next. Although laser heat treatment is in abroad to be inferior to,solder and cut is general, but still apply in auto industry extensive, wait for the heat treatment of component like annulus of cylinder bushing, crankshaft, piston, commutator, gear. In industrial developed country, technology of laser beam machining and technology of computerized numerical control and flexible production technology photograph is united in wedlock, derive gives laser to become form technology quickly. This technology can make a model quickly not only, and OK still and direct by metallic powder melt, create a metallic pattern. Arrived 80 time, YAG laser is soldering, the respect such as cut, stiletto and mark produced bigger and bigger effect. The cut quality that thinks YAG laser cut can have gotten normally and tall cut precision, but be restricted on cut speed. Rise as what YAG laser outputs power and quality of beam of light and be broken through. YAG laser already began to be squeezed into market of cut of laser of Kw class CO2. YAG laser suits to solder not to allow to heat is out of shape and solder particularly miniature parts of an apparatus of pollution, the batteries that be like lithium, pacemaker, sealed relay. YAG laser stiletto already developed make application of the biggest laser beam machining. Current, foreign laser stiletto basically applies in aerospace, car to make, the industry such as electronic appearance, chemical industry. The rapid development of laser stiletto, main body used the average output power of YAG laser to already raised 800w by the 400w 5 years ago to 1000w in stiletto now. Power of stiletto peak value is as high as 30~50kw, the pulse width that stiletto uses is narrower and narrower, repeat frequency taller and taller, of laser output parameter rise, improved stiletto quality greatly, raised stiletto rate, also enlarged the applied limits of stiletto. In the production that the application of the laser stiletto that home matures quite at present is the production that hauls filar model in making synthetic diamond and natural diamond and watch gem bearing. The stress that at present technology of laser beam machining studies to develop but reduce: Laser of new generation industry studies, the newer period that goes up at the technology at present, its indicate the development that is laser of whole solid state of diode pump riverside reachs application; Careful laser beam machining, imperceptible in statistic of application of laser beam machining treatment occupied 6 ％ only 1996, broke up 1997 one times amount to 12 ％ , already increased 19 ％ 1998; Treatment system intelligence is changed, the system is compositive it is treatment itself not only, contain real time to detect however, feedback processing, as expert system build, treatment system intelligence is changed already made inevitable development trend. Laser technology passes 30 old development in our country, obtained positive result of on 1000 science and technology, a lot of already used at producing practice, yield of equipment of laser beam machining is average and annual grow with the speed of 20 ％ , the technical reformation that is traditional industry, raised product quality to solve a lot of problems, if laser wool changes fine technology to be in the large section factory such as this treasure steel, steel to popularize, the change our country car is covered the state that armor plate counts an import completely, laser sign chance and laser beam welding receive the quality of machine, function, price to accord with home at present the demand of the market, the market is had rate amount to 90 ％ above. Put the main problem that be in: The ability of commodity of translate into of scientific research achievement is poor, a lot of positive result that have market perspective stay in the prototype phase of the lab; The breed of the core component laser of system of laser beam machining backward, dependability needs little, technology. Abroad not only the laser of whole solid state of diode pump riverside already was used in manufacturing process, and diode laser also is applied, and the laser of whole solid state of riverside of our country diode pump still lies to just began to consider to develop level. Little to the research of processing technique, be opposite especially the research of careful processing technique is more fragile, right ultraviolet what wave laser undertakes the research of treatment undertakes is few. The dependability of equipment of laser beam machining, security, but sex of maintainability, form a complete set is poorer, satisfy the need that industry produces hard. CNC Milling
