Carbon steel
Nekuti kabhoni simbi ine kabhoni, hairatidzi chiedza zvakasimba uye inotora mwenje wechiedza zvakanaka.Carbon simbi yakakodzera kucheka laser mune zvese simbi zvinhu.Naizvozvo, kabhoni simbi laser yekucheka michina ine isingazununguke chinzvimbo mucarbon simbi kugadzirisa.
Iko kushandiswa kwekabhoni simbi kuri kuramba kuchiwedzera.Mazuvanolaser yekucheka michinainogona kucheka ukobvu hwepamusoro hwekabhoni simbi mahwendefa kusvika ku20MM.Iyo slit yekucheka kabhoni simbi uchishandisa iyo oxidative kunyungudika uye kucheka michina inogona kudzorwa kune inogutsa hupamhi.Kusvika ku0.1MM.
Simbi isina ngura
Laser yekucheka Stainless simbi inoshandisa simba rinoburitswa kana laser beam yakavhenekerwa pamusoro peplate resimbi kunyungudusa uye kuburitsa simbi isina tsvina.Kune iyo indasitiri yekugadzira iyo inoshandisa Stainless simbi sheet sechinhu chikuru, laser yekucheka Stainless simbi inokurumidza uye inoshanda nzira yekugadzirisa.Iwo akakosha maitiro ma paramita anobata kunaka kwekucheka kwesimbi isina simbi ndeyekucheka kumhanya, laser simba, uye mhepo yekumanikidza.
Kuenzaniswa nesimbi yakaderera kabhoni, simbi isina tsvina yekucheka inoda yakakwira laser simba uye oksijeni kumanikidza.Kunyangwe simbi isina tsvina yekucheka inowana inogutsa yekucheka mhedzisiro, zvakaoma kuwana zvachose-isina slag-yekucheka seams.High pressure nitrogen uye The laser beam inobaiwa coaxially kuti ifuridze simbi yakanyungudutswa kuitira kuti pasave neooxide inoumbwa panzvimbo yekucheka.Iyi inzira yakanaka, asi inodhura kupfuura tsika yekucheka okisijeni.Imwe nzira yekutsiva yakachena nitrogen ndeyekushandisa yakasefa chirimwa chakadzvanywa mweya, uyo une 78% nitrogen.
Kana laser yekucheka girazi simbi isina tsvina, kuitira kudzivirira bhodhi kubva pakupisa kwakanyanya, laser film inodiwa!
Aluminium uye alloy
Kunyangwe iyo laser yekucheka muchina inogona kushandiswa zvakanyanya mukugadziriswa kweakasiyana simbi uye asiri-simbi zvinhu.Nekudaro, zvimwe zvinhu, zvakaita semhangura, aruminiyamu, uye alloys adzo, anoita kuti laser yekucheka iome kugadzirisa nekuda kwehunhu hwayo (yepamusoro reflectivity).
Parizvino, aluminium plate laser yekucheka, fiber lasers uye YAG lasers inoshandiswa zvakanyanya.Midziyo miviri iyi inoita zvakanaka mukucheka aruminiyamu nezvimwe zvinhu, sesimbi isina simbi uye kabhoni simbi, asi hapana inogona kugadziriswa zvakakora.Aluminium.Kazhinji, ukobvu hwe6000W hunogona kutemwa kusvika 16mm, uye 4500W inogona kutemwa kusvika 12mm, asi mutengo wekugadzirisa wakakwira.Iyo yekubatsira gasi rinoshandiswa rinonyanya kushandiswa kupeperetsa kunze chigadzirwa chakanyungudutswa kubva munzvimbo yekucheka, uye kazhinji iri nani yakachekwa yemhando yepamusoro inogona kuwanikwa.Kune mamwe aruminiyamu alloys, kutarisisa kunofanirwa kubhadharwa kudzivirira micro-kutsemuka pamusoro peiyo slit.
Mhangura uye alloys
Mhangura yakachena (mhangura) haigone kutemwa ne CO2 laser beam nekuda kwekunyanya kutaridzika kwayo.Brass (copper alloy) inoshandisa yakakwirira laser simba, uye gasi rinobatsira rinoshandisa mweya kana oxygen, inogona kucheka mahwendefa matete.
Titanium uye alloys
Laser kucheka kwetitanium alloys inowanzoshandiswa muindasitiri yendege ine mhando yakanaka.Kunyangwe pachange paine diki inonamira yakasara pazasi pekatsemuka, zviri nyore kubvisa.Yakachena titanium inogona kunyatsobatanidzwa pamwe neiyo inopisa simba inoshandurwa neinotariswa laser beam.Apo gasi rinobatsira rinoshandisa okisijeni, makemikari anoita anotyisa uye kukurumidza kucheka kunokurumidza.Zvisinei, zviri nyore kuumba oxide layer pamucheto wekucheka, uye kupisa netsaona kunogonawo kuitika.Nekuda kwekugadzikana, zviri nani kushandisa mhepo seyanobatsira gasi kuve nechokwadi chekucheka mhando.
Alloy simbi
Mazhinji alloy zvimiro simbi uye alloy mudziyo simbi inogona kuchekwa laser kuti iwane yakanaka yekucheka kumucheto mhando.Kunyangwe kune zvimwe zvinhu zvepamusoro-simba, chero bedzi maitiro ekugadzirisa akadzorwa zvakanaka, yakatwasuka uye isina slag-isina kucheka mipendero inogona kuwanikwa.Nekudaro, kune tungsten-ine high-speed tool simbi uye inopisa-mold simbi, ablation uye slagging inoitika panguva yekucheka laser.
Nickel alloy
Kune akawanda marudzi e nickel-based alloys.Mazhinji acho anogona kuve pasi pe oxidative fusion yekucheka.
