Metal laser cutting umshini kungaba sicubungula izinto, nakuba cishe zonke izinto zensimbi has a reflectivity eliphezulu infrared wave amandla ekamelweni lokushisa, kodwa kwethulwa kude-infrared band 10.6 um ngemishayo CO2 laser sisetshenziswa ngempumelelo umkhuba eziningi zensimbi laser cutting .Metal ukuze 10.6 um ukumuncwa rate Nokho kuyinto% 0.5 kuphela ~ 10%, futhi ekuqaleni ugongolo laser, lapho amandla kwabantu abangaphezu kuka-106 w / cm2 igxile laser ugongolo kwamanzi metal, kodwa ukwenza ebusweni ngokushesha isikhathi microsecond waqala melt.In iningi oncibilikisiwe ukumuncwa metal izinga imba eqolo, ngokuvamile kungenziwa kunyuke ngo-60% ~ 80%.
1, carbon steel
laser Modern ahlabayo uhlelo usike carbon steel plate ukujiya kuya ku-20 MM, ukusetshenziswa namachibi ukuncibilika cutting inqubo ukusika carbon steel cutting umphetho ububanzi zingalawulwa etinhlotjeni letibanti egculisayo, ukuze unciphise ishidi ububanzi kerf kungaba 0.1 MM noma ngakho.
2, insimbi engagqwali
Laser cutting of engagqwali ishidi isetshenziswa njengoba ingxenye main kuba amathuluzi ngempumelelo machining manufacturing.In ukulawula okuqinile okokufaka ukushisa e inqubo laser zokwehlisa izindleko, unganciphisa ilungiswe ukushisa indawo abathintekayo incane, ngaleyo ndlela silondoloze ngempumelelo ukumelana okuhle ukugqwala saloluhlobo impahla.
3, ingxubevange steel
Iningi ingxubevange steel kwesakhiwo ingxubevange steel ithuluzi Ungasebenzisa laser cutting indlela ezinhle ilungiswe quality.Even okunye okubalulekile namandla high, inqobo nje nemingcele inqubo zilawulwa ngendlela efanele, flat, okungezona ezisalayo okunamathelayo ilungiswe ingatholakala .Kodwa ngesivinini ithuluzi lezinsimbi equkethe tungsten futhi kushisa die steel, laser cutting ne ukugqwala futhi viscous slag mkhuba.
4, aluminium and ingxubevange
Aluminium ahlabayo zingezikaJehova ancibilike ukusika indlela, igesi asizayo ikakhulukazi ezisetshenziswe ngesikhathi kuqhunyiswa kude umkhiqizo oncibilikisiwe kusuka endaweni cutting, ngokuvamile ungakwazi ukuthola izinga kangcono aspects.For ezinye ingxubevange aluminium, ukunakekelwa okufanele ikhokhwe ukuvimbela ukusika umphetho ukuvundulula intergranular imifantu micro.
5, nethusi ingxubevange
Pure copper (copper) because of high reflectivity, basically can't use CO2 laser cutting.Use higher laser power of brass (copper), auxiliary gas with air or oxygen, the thinner plates can be cut.
6, titanium and ingxubevange
Pure titanium can coupling focused laser beam transformation of heat energy, auxiliary gas using oxygen chemical reaction is intense, cutting speed faster, but easy to generate oxide layer in trimming, accidentally can also cause a burn.As safe, using air as auxiliary gas is better, to make sure that the cutting quality.Aircraft industry commonly used titanium alloy laser cutting quality is better, although there will be a little sticky residue at the bottom of the kerf width, but it's easy to remove.
7, nickel ingxubevange
ingxubevange Nickel ezisekelwe ubizwa nangokuthi super ingxubevange, abaningi varieties.Most wabo ezingase zithathwe namachibi ukuncibilika ahlabayo.
