The choice of laser beam cutting machine, gets " high quality " the crucial factor of cut included: The width of cut (the loss of cut office data) , the oxidation of cut surface and crude rate, and the on size error with concessional place. The crucial factor that undertakes cut operates included: Cut speed, the flexibility of the operation, concessional public errand, and production and the handy sex of the process that start.
Laser power
In fact, not be laser power rate of larger part treatment is rapidder, still other factor meets those who affect cut rate rise. The type of laser resonance antrum can affect the cut speed of whole system and cost effectiveness. The increased to enlarge laser application with the improvement of quality of beam of light scope of laser power. The 2 KW of power prep above of major laser system, and the system that already power is more than 7 KW now can be offerred use. Raise what power does not bring cut rate certainly. In the course that cuts eagerly, power exceeds 3 or when 4 KW, the heat that enlarges material possibly affects area, ask to drive system thereby taller, because this limitted cut rate.
To certain material, the influence of quality of beam of light to cut speed and no less than laser power. CO2 laser basis is syntonic of antrum different and OK the kind that has all sorts of differring: Fast axis sheds laser, crosscurrent laser, diffuse cooling laser (or attrib wattle laser) . Type of every kinds of syntonic speech gets quality of different beam of light and Jiao Ban diameter, and different laser power. Diffuse the quality of beam of light of cooling laser may be better, but general power is restricted. Fast axis flows and crosscurrent laser can produce power to be in the laser of 6-7 KW, but quality of beam of light begins possibly to drop in 4 KW above.
The consideration that the metal machines
Higher laser power basically conduces to increase the ply that can process data. For the carbon steel cut that serves as auxiliary gas to oxygen, as power rise, receive makings rate and do not have the addition of materiality. Because heat up the existence of reaction process, power / existing into makings rate an upper limit, corresponding this maximum, can cut is definite the material of ply. Action is on material of power rise and cannot transform automatically rise for what material machines speed.
Nitrogen of use high pressure is opposite as auxiliary gas thick stainless steel board undertake cut can get do not have oxidation cut. For instance, laser of 6.0 KW CO2 can machine ply to amount to 11/4 inch stainless steel. In high pressure or in process of inert gase cut, the main function of auxiliary gas is protection cut brim is unapt form oxidation, and the material melt is very fast blow clean, avoid to they are stuck in the brim and form Mao Bian thereby.
Because raise cut power to be able to bring about cost to rise, so if can bring more economic benefits, so enhancing power also is feasible. Current, the ply of metallic thin plate that requires treatment for the most part amounts to 6 Mm, those who use is power undertakes machining for the laser of 3.5 KW, when treatment speed needs to rise, laser power can enhance below the circumstance that assures quality of beam of light.
