Namhlanje, phantse yonke i-laser echanekileyo yokusika isinyithi kunye ne-non-metals yenziwa kusetyenziswa izixhobo ezixhotyiswe nge-fiber lasers okanye i-ultrashort pulse (USP) lasers, okanye ngamanye amaxesha zombini.Kweli nqaku, siza kuchaza iingenelo ezahlukeneyo ze-laser ezimbini kwaye sibone indlela abavelisi bobabini abasebenzisa ngayo ezi lasers.NPX Medical (Plymouth, MN) yinkontileka ekhethekileyo yezixhobo zokusebenza kunye nezixhobo ze-steflex ezenza izixhobo ezikhethekileyo ze-steflex kunye ne-implants, i-implants kunye nezixhobo ezikhethekileyo zokulungisa izixhobo, kunye ne-implants. i-bing, usebenzisa oomatshini ababandakanya i-fiber lasers.I-Motion Dynamics ivelisa ii-subassemblies, ezifana neendibano ze-"pull wire" ezisetyenziswa ngokuyinhloko kwi-neurology, usebenzisa umatshini oquka i-USP femtosecond laser kunye nenye yeenkqubo zamva nje ze-hybrid ezibandakanya i-femtosecond kunye ne-fiber lasers ukwenzela ukuguquguquka okukhulu kunye ne-Versatility.
Kwiminyaka emininzi, uninzi lwe-laser micromachining luye lwenziwa kusetyenziswa i-slid-state nanosecond lasers ebizwa ngokuba yi-DPSS lasers. Nangona kunjalo, oku kuye kwatshintsha ngokupheleleyo umbulelo kuphuhliso lweelaser ezimbini ezahlukeneyo ngokupheleleyo, kwaye ke ngoko ziyancedisana, iintlobo zelaser.Eziphuhliselwe unxibelelwano, iilaser zefiber ziye zakhula zaba yi-workhorse process lasers kumashishini amaninzi, ahlala ekufutshane kwi-waveleng-lidecture. ward power scalability.Oku kubangela iilases ezihlangeneyo, ezithembeke kakhulu, kwaye kulula ukudibanisa koomatshini abakhethekileyo, kwaye ngokubanzi zibonelela ngexabiso eliphantsi lobunini kuneentlobo zakudala ze-laser.Okubalulekileyo kwi-micromachining, i-beam ephumayo inokujoliswa kwindawo encinci, ecocekileyo yee-microns ezimbalwa kuphela ububanzi, ngoko ke zilungele ukugqitywa kwe-high-resolution kunye ne-flexible drilling kunye ne-flexible drilling, i-flexible drilling kunye nokulawulwa kwe-flexible. ukusuka kwi-shot eyodwa ukuya kwi-170 kHz. Ngoku kunye namandla anokunyuka, oku kuxhasa ukusika kunye nokugrumba ngokukhawuleza.
Nangona kunjalo, ukungonakali okunokubakho kwe-fiber lasers kwi-micromachining kukwenziwa kweempawu ezincinci kunye/okanye ezibhityileyo, iindawo ezibuthathaka.Ixesha elide (umzekelo, i-50 µs) ipulse durations likhokelela kwindawo encinci echaphazelekileyo ubushushu (HAZ) njengezinto eziphindiweyo kunye noburhabaxa obuncinci bomphetho, obunokufuna i-post-processing, i-US d i-pulses yemveliso-ukuphelisa ingxaki ye-HAZ.
Ngama-laser e-USP, ubuninzi bobushushu obongezelelweyo obunxulumene nokusika okanye inkqubo yokugaya ithathwa kwi-debris ejected ngaphambi kokuba ibe nexesha lokusabalalisa kwizinto ezijikelezileyo.I-laser ye-USP enemveliso ye-piccosecond sele isetyenziswe kwizicelo ze-micromachining ezibandakanya iiplastiki, i-semiconductors, i-ceramics, kunye neentsimbi ezithile (i-picoseconds = i-picoconds = i-picoseconds = i-picoseconds = i-10-12 ye-metal, i-metal i-devices, i-10-12 ye-metal, kodwa i-metal isayizi ye-10-12 yezixhobo eziphezulu ze-metal). mal conductivity kunye nobukhulu obuncinci buthetha ukuba i-lasecond lasers ayisoloko ibonelela ngeziphumo eziphuculweyo eziza kulungelelanisa iindleko ezongezelelweyo ze-USP lasers zangaphambili.Oku kutshintshile ngoku ngokufika kwe-industrial grade femtosecond lasers (femtosecond = 10-15 imizuzwana) .Umzekelo yi-Coherent Inc.'s I-Inc.'s i-Monaco ephumayo i-Monaco ephumayo i-fiber ye-laser okanye i-laser-france i-metal france i-fiber ye-laser. isetyenziswe kwizixhobo zonyango, kubandakanywa insimbi engenasici, iplatinum, igolide, i-magnesium, i-cobalt-chromium, i-titanium, kunye nokunye, kunye neentsimbi ezingezizo.Ngelixa udibaniso lwexesha elifutshane le-pulse kunye ne-low pulse energy lithintela umonakalo wokushisa (HAZ), izinga eliphezulu (MHz) lokuphindaphinda liqinisekisa indleko-esebenzayo-ixabiso eliphezulu lokusebenzisa izixhobo zonyango ezininzi.
Ngokuqinisekileyo, phantse akukho mntu kwishishini lethu ufuna i-laser enye kuphela.Kunokuba bafune umatshini osekelwe kwi-laser, kwaye ngoku kukho oomatshini abaninzi abakhethekileyo abalungiselelwe ukusika kunye nokugrumba izixhobo zonyango.Umzekelo yi-Coherent's StarCut Tube series, enokusetyenziswa nge-fiber lasers, i-laser ye-femtosecond, okanye njengenguqulo ye-hybride ebandakanya zombini iintlobo ze-laser.
Kuthetha ukuthini ubugcisa besixhobo sonyango?Uninzi lwezi zixhobo ziveliswa kwiibhetshi ezilinganiselweyo ezisekelwe kuyilo lwesiko.Ngoko ke, ukuguquguquka kunye nokulula kokusetyenziswa zizinto eziphambili zokuqwalaselwa.Ngelixa izixhobo ezininzi zenziwe ngeebhilidi, ezinye iinqununu kufuneka zichaneke zenziwe ngoomatshini kwiibhilithi ezicaba;umatshini ofanayo kufuneka uphathe zombini ukunyusa ixabiso layo.Ezi zidingo zidla ngokubonelelwa ngokubonelela nge-multi-axis CNC elawulwayo (xyz kunye ne-rotary) intshukumo kunye ne-HMI ehambelana nomsebenzisi weprogram elula kunye nokulawula.Kwimeko ye-StarCut Tube, imodyuli entsha yokulayishwa kwe-tube iza kunye nomagazini wokulayishwa kwecala (obizwa ngokuba yi-StarFeed) kwiityhubhu ukuya kwi-3 m ubude beemveliso ezisikiweyo kunye nemveliso ye-automa.
Ukuguquguquka kwenkqubo yaba matshini kuphuculwe ngakumbi ngenkxaso yokusika okumanzi kunye nokomileyo kunye nemibhobho yonikezelo elungelelanisiweyo ngokulula kwiinkqubo ezifuna uncedo lwe-gas.Isisombululo se-Spatial nayo ibaluleke kakhulu kwi-machining iindawo ezincinci kakhulu, nto leyo ethetha ukuba ukuzinza kwe-thermomechanical kuphelisa imiphumo ye-vibration edla ngokudibana nayo kwiivenkile zoomatshini.Uluhlu lwe-StarCut Tube luhlangabezana nale mfuno ngokwakha inani elikhulu le-granite yokusika.
