In 10 years of in the past, industrial data treatment already came true with the market of laser product annual the growth of two digit. Accompanying the progress of laser illuminant technology, and of limits of application of system of laser beam machining extend and optimize, laser technology has become an efficient, reliable process instrumentation in numerous domain. Auto industry and industry of general Sheet Metal Fabrication are laser reachs his the drive source of relevant technology progress and development. In these industries, the laser source that outputs power higher and quality of higher beam of light extended the applied range of laser technology. Carbon dioxide laser because its are tall quality of output power, beam of light is fine, operate easily, and have a system together easily compositive, in making laser industry, heavy load machines systematic main force. The carbon dioxide laser that estimation has 60 ％ is used to make cut application. Most laser plank machines a system to all use the carbon dioxide laser of 1 ～ 3KW. Nowadays, to seek higher treatment rate, the user considers to choose the laser that outputs power higher ceaselessly, but increase output power to you can achieve higher treatment rate in fact? The demand that outputs power higher to outputting the demand of power higher to be opposite does not have end. But, higher output power always is not meant can achieve higher treatment rate. Because effective treatment is medium unlikely that fulfil the quota uses his of laser can output power. If the ply of material is 1mm,come 6mm, citing, the laser power that uses fulfil the quota impossibly commonly will process work, no matter it is medium carbon steel, stainless steel or aluminium. Increase laser power to the value that exceeds a need continuously in the course that cuts eagerly, the hot influence division that causes material possibly expands, ask slowdown of mechanical movement system, cause cut rate thereby reduce. Because this is become the ply of plate of Laser Cutting metal not when prep above 4mm, handlers is used commonly far under the output of 2KW power is machined. Be in to ply even the plank of 4mm ～ 6mm, if use the laser of a 5KW, handlers also often also needs to move low power, use the output power that does not exceed 2KW to make cut treatment. When cut large board expects, experimental result makes clear, increase to output power and cannot raise cut rate of laser significantly. See a picture 1, in cut 15mm, 20mm, 25mm medium carbon steel when these large board expect, laser power from 2.

5KW raises 5KW but can not realize cut speed twice increase. Graph the treatment rate with 1 higher to outputting power to obtain through increasing laser photograph, we more first consideration outputs apt power is proper, but the laser with better quality of beam of light will improve treatment efficiency. To plate material cut, of Rofin-Sinar company diffuse cool style laser of carbon dioxide batten is an optimal choice undoubtedly. Use diffuse laser of carbon dioxide batten uses cooling formula of new patent technology diffuse laser of batten of cooling carbon dioxide, can get quality of higher beam of light and smaller focusing facula diameter, see a picture 2. Graph the syntonic antrum of 2 laser by before lens, hind lens and two radio frequency electrode that parallel places are comprised. The radio frequency that connects water to cool in two to the drive of laser gas undertakes between electrode. In discharge drive process, the quantity of heat that laser gas produces is taken away by water-cooled electrode (diffuse cooling) . Accordingly, be absent the aeriform circulatory system that needs a convention, include collect Ci booster pump or turbine. Figuration of compositive in laser head beam of light is unit, can come true high quality, even round facula. The design of syntonic antrum, realized the output of beam of light of 45 degrees of linear polarizations. These features came true narrower cut seam, because fewer data is moved to divide in cut, can raise cut rate significantly so. Accordingly, diffuse the cut that the laser of carbon dioxide batten of cool style suits laminose metal particularly. Graph 3 show 3 times like the graph, use 2.

The cut speed of medium carbon steel of cut of laser of batten of 5KW carbon dioxide, the posture that can adopt the axis of traditional pattern to shed 4KW of carbon dioxide laser quickly to be able to come true together is rivalled. Become only when 10mm of plate thickness prep above, the distinction of cut speed just is shown. Undertaking to aluminous material laser fuses when cut (see a picture 4) , the advantage of character of tall beam of light will be developed more apparently. In the ply under 2mm, the cut rate that attrib wattle laser can achieve, the carbon dioxide laser of type of flow of far outclass gas. In the interval of 2mm~4mm, the result that two laser achieve is very adjacent. Graph 4 when material of cut stainless steel, we also discovered similar result. Saving moving charge another to concern laser to run the main factor of cost is the design of laser. For example, diffuse layout of laser of batten of cooling carbon dioxide is concise, syntonic antrum only two speculum reflex material piece. Diffuse to design a principle coolingly, slam the door turbine and air-blower drive gas systematic circulation, realized the extremely small loss of laser. Because carbon dioxide is attrib wattle,flow, the machine that start can realize laser to output. And the carbon dioxide laser that the axis sheds quickly needs a longer time that start, use up many gas, and, in bide one's time when condition, must keep the movement of turbine and air-blower, waste too much electric energy. Diffuse the laser gas that the laser of carbon dioxide batten of cool style uses has mixed beforehand, the gas cylinder of premixed gases is compositive in laser head, need not the supply of exterior gas, of a bottle of premixed gases use up cycle about 1 year (with 2.

5KW is exemple) , the cost that because this gas uses up place,causes is negligible even not plan. When the aeriform work out of gas cylinder, need to change a bottle again only new, the machine can continue to run to use up cycle newly. Of course, the difference that attrib wattle laser and axis sort laser quickly and compare a dominant position a few what place of far more than above narrates, in lens service life, safeguard a lot of respect such as removed, thermal stability, attrib wattle laser reflects the clear advantage that gave to regard the 3rd generation as carbon dioxide laser. Increase power when needing higher power in view of increase power to mean raise cost. Achieve taller treatment efficiency to coming through increasing power, we more apt is preferential the laser with higher quality of consideration beam of light. To the plank of ply of 4 ～ 6mm, namely the mainest limits that plate material machines nowadays, use 2.

The laser of attrib wattle carbon dioxide of 5KW, make full use of the advantage of character of tall beam of light, can realize high-speed treatment. In another respect, source of high power laser is OK with taller rate cut deeper work. When the user expects to achieve higher cut rate, must be in the investment cost with all sorts of higher laser and raise moving cost careful balance. When the board that needs treatment when you is given priority to with large board makings, the laser that uses higher power just is necessary. Additional, cut large board expects, the result that the axis that the view previously is high power sheds laser quickly wants excel the attrib wattle laser of coequal power, however, the laser of attrib wattle carbon dioxide of higher power (4KW, 5KW) cooperates 7.

5 " + 20 " the cut head of focal length, its treatment speed and cut seam quality, shed the axis of coequal power quickly laser to be swung at the back aloof again, continued laser of attrib wattle carbon dioxide the consistent dominant position in Laser Cutting domain. The laser that sums up higher power means higher investment cost, operation cost and specific power consumption, using up what give priority to a problem with environmental protection with managing the sources of energy today, we more recommend when choosing laser, no matter be solid laser or carbon dioxide laser, the laser with more fine quality of first consideration beam of light, below premise of outstanding character of beam of light, choose appropriate output power appropriately again. Quality of fine beam of light is the objective that laser production manufacturer pursues, also be the key that machines character and efficiency! CNC Milling CNC Machining
