Namuhla, cishe konke ukusika kwe-laser okunembayo kwezinsimbi nezingezona zensimbi kwenziwa kusetshenziswa amathuluzi afakwe amalaser e-fiber noma ama-laser e-ultrashort pulse (USP), noma ngezinye izikhathi kokubili.Kulesi sihloko, sizochaza izinzuzo ezihlukene zamalaser amabili futhi sibone ukuthi bobabili abakhiqizi bawasebenzisa kanjani la ma-lasers. i-bing, kusetshenziswa imishini ehlanganisa i-fiber lasers.I-Motion Dynamics ikhiqiza ama-subassemblies, njengemihlangano “ye-pull wire” esetshenziswa ngokuyinhloko ku-neurology, isebenzisa umshini ohlanganisa i-USP femtosecond laser kanye nolunye lwezinhlelo zakamuva ze-hybrid ezihlanganisa i-femtosecond ne-fiber lasers ukuze kube nokuguquguquka okukhulu nokuhlukahluka.
Sekuyiminyaka eminingi, iningi le-laser micromachining lenziwa kusetshenziswa ama-solid state nanosecond lasers abizwa ngokuthi ama-laser e-DPSS. Nokho, lokhu manje sekushintshe ngokuphelele ngenxa yokuthuthukiswa kwezinhlobo ze-laser ezimbili ezihluke ngokuphelele, ngakho-ke ezihambisanayo.Ekuqaleni zenzelwe ukuxhumana ngezingcingo, ama-fiber lasers asekhulile aba ama-laser okucubungula izinto ezisetshenziswayo ezimbonini eziningi, ahlanganiswe nezizathu eziqondile ze-waveleng yayo ngenxa yezizathu eziqondile ze-waveleng. Ukwehla kwamandla esigceme.Lokhu kuphumela kuma-laser ahlangene, athembeke kakhulu, futhi okulula ukuwahlanganisa emishinini ekhethekile, futhi ngokuvamile anikeza izindleko eziphansi zobunikazi kunezinhlobo ze-laser ezindala.Okubalulekile nge-micromachining, ugongolo okukhiphayo lungagxilwa endaweni encane, ehlanzekile yama-microns ambalwa kuphela ububanzi, ngakho alungele ukubhoboza okunesixazululo esiphezulu futhi okuphumayo okuguquguqukayo okuguquguqukayo kukhona okuphumayo okuguquguqukayo, okuguquguqukayo nokushisela okuhlukahlukene. kusukela ekudutshulweni okukodwa kuya ku-170 kHz. Kanye namandla angaka, lokhu kusekela ukusika nokubhoboza okusheshayo.
Kodwa-ke, ubungozi obungaba khona be-fiber lasers ku-micromachining ukwenziwa kwezici ezincane kanye/noma izingxenye ezincane, ezithambile. Ubude be-pulse ubude (isb., 50 µs) buphumela endaweni encane ethinteke ekushiseni (HAZ) okufana nokusakazwa kabusha kanye nobulukhuni obuncane bonqenqema, okungase kudinge ukucutshungulwa kwe-laser yase-US, ngenhlanhla ne-laser. d ama-pulses okukhiphayo-susa inkinga ye-HAZ.
Ngama-laser e-USP, ukushisa okuningi okwengeziwe okuhlobene nenqubo yokusika noma yokumba kuhanjiswa emfucumfucwini ekhishiwe ngaphambi kokuba kube nesikhathi sokusakazeka ezintweni ezizungezile.Ama-laser e-USP ane-piccosecond okukhiphayo kudala asetshenziswa ekusetshenzisweni kwe-micromachining okubandakanya amapulasitiki, ama-semiconductors, i-ceramics, nezinsimbi ezithile (picoseconds = 10-12 yensimbi yensimbi ephezulu, i-metal size ye-10-12 yensimbi ephezulu). ukungaphatheki kahle kanye nosayizi omncane kusho ukuthi ama-lasecond lasers awanikezi ngaso sonke isikhathi imiphumela ethuthukisiwe engathethelela izindleko ezikhuphukile zamalaser e-USP angaphambili. Lokhu manje sekushintshile ngokufika kwama-laser e-femtosecond esezingeni lezimboni (femtosecond = 10-15 seconds). Isibonelo yi-Coherent Inc.'s Monaco's okusho ukuthi i-Monaco ephumayo eduze nochungechunge lwama-laser-fra ingakwazi ukusika uchungechunge lwama-laser wensimbi, iLili i-fiber ekhishwayo. esetshenziswa kumishini yezokwelapha, okuhlanganisa insimbi engagqwali, iplatinum, igolide, i-magnesium, i-cobalt-chromium, i-titanium, nokuningi, kanye nezingezona izinsimbi.Yize inhlanganisela yobude besikhathi sokushaya kwenhliziyo emfushane namandla aphansi we-pulse ivimbela ukulimala okushisayo (HAZ), izinga eliphezulu (MHz) lokuphindaphinda liqinisekisa isivinini esingabizi kakhulu se-output-value kumadivayisi wezokwelapha amaningi.
Yebo, cishe akekho umuntu embonini yethu odinga i-laser eyodwa. Kunalokho, badinga umshini osekelwe nge-laser, futhi manje sekunemishini eminingi ekhethekile elungiselelwe ukusika nokubhoboza amathuluzi ezokwelapha.Isibonelo uchungechunge lwe-Coherent's StarCut Tube, olungasetshenziswa ngama-fiber lasers, ama-laser e-femtosecond, noma njengenguqulo ye-hybrid ehlanganisa zombili izinhlobo ze-laser.
Kusho ukuthini ukwazi ngemishini yezokwelapha?Iningi lale mishini ikhiqizwa ngamaqoqwana anqunyelwe ngokusekelwe emiklamweni yangokwezifiso.Ngakho-ke, ukuguquguquka nokusebenziseka kalula kuyizinto ezicatshangelwayo ezibalulekile.Nakuba amadivaysi amaningi enziwa ngamabhilidi, ezinye izingxenye kufanele zenziwe ngokunemba ngomshini ngamabhilidi ayisicaba;umshini ofanayo kufanele uphathe kokubili ukuze ukwandise inani lawo.Lezi zidingo zivame ukuhlangatshezwana nazo ngokuhlinzeka ngokunyakaza kwe-CNC elawulwa yi-multi-axis (xyz ne-rotary) kanye ne-HMI esebenziseka kalula ye-HMI yokuhlela nokulawula okulula.Endabeni ye-StarCut Tube, inketho yemoduli yokulayisha ishubhu entsha iza nomagazini wokulayisha oseceleni (obizwa nge-StarFeed) wamashubhu afinyelela ku-3 m ubude bokukhiqiza okuzenzakalelayo kanye nokukhiqiza okuzenzakalelayo okuzenzakalelayo.
Ukuguquguquka kwenqubo yale mishini kuthuthukiswa ngokwengeziwe ngokusekelwa kokusika okumanzi nokomile kanye nemibhobho yokulethwa elungiseka kalula yezinqubo ezidinga igesi yokusiza. Ukulungiswa kwendawo nakho kubaluleke kakhulu ekwenzeni izingxenye ezincane kakhulu, okusho ukuthi ukuzinza kwe-thermomechanical kuqeda imiphumela yokudlidliza okuvame ukuhlangana nayo ezitolo zemishini.I-StarCut Tube range ihlangabezana nalesi sidingo ngokwakha inombolo enkulu ye-granite yenombolo.
I-NPX Medical ingumkhiqizi omusha wenkontileka ohlinzeka ngemisebenzi, ubunjiniyela kanye nokunemba kwama-Laser Cutting Services kubakhiqizi bedivaysi yezokwelapha. Ukuhlinzwa kwesistimu, kanye ne-gastrointestinal Yazi ukuthi ama-lacers e-fiber anganikeza isivinini kanye nekhwalithi esiyidingayo.Izinto ezifana nama-tubis anama-batch anama-batch aphezulu - I-USP Laser ukuqedela lezi zingcezu eziphakeme ze-batch ezinsukwini ezimbalwa - sisebenza kakhulu - ukucubungula kanye nokuhlola, kuqhathaniswa namasonto ngemuva kwe I-oda libekwe ezinkampanini ezinkulu. "Ngaphezu kokusho isivinini, uBrenzel ukhulume ngokuthembela komshini njengenzuzo enkulu, engafuni ukubizwa kwensizakalo eyodwa ezinyangeni eziyi-18 ezedlule zokusebenza okuzayo.
Umfanekiso 2. I-NPX inikeza izinhlobonhlobo zezinketho zangemuva kokucubungula.Impahla eboniswe lapha yi-T316 yensimbi engagqwali ene-5mm OD ne-0.254mm odongeni ubukhulu.Ingxenye engakwesobunxele iyasikwa / i-microblasted futhi ingxenye efanele i-electropolished.
Ngaphandle kwezingxenye ze-nitinol, inkampani iphinde isebenzise kakhulu ama-alloys e-cobalt-chromium, ama-tantalum alloys, ama-titanium alloys kanye nezinhlobo eziningi zezinsimbi ezingenasici zezokwelapha.UJeff Hansen, Umphathi Wokucubungula I-Laser, uyachaza: "Ukuguquguquka komshini kungenye impahla ebalulekile, okusivumela ukuba sisekele ukusika uhla oluhluke kakhulu lwezinto zokwakha, okuhlanganisa ishubhu ne-flat.Singakwazi ukugxilisa i-beam phansi endaweni engama-micron angu-20, okuwusizo kwamanye amashubhu azacile awusizo kakhulu.Amanye alawa mashubhu angu-0.012″ ID kuphela, futhi isilinganiso esiphezulu samandla aphezulu kumandla amaphakathi wama-laser akamuva efiber akhulisa isivinini sethu sokusika kuyilapho sisanikeza ikhwalithi yomkhawulo esiyifunayo.Sidinga ngokuphelele isivinini semikhiqizo emikhulu enobubanzi obungafika ku-intshi engu-1.”
Ngokungeziwe ekusikeni okunembayo nokuphendula ngokushesha, i-NPX iphinde inikeze uhla oluphelele lobuchwepheshe bangemva kokucubungula, kanye nezinsizakalo zokuklama ezibanzi ezithuthukisa ulwazi lwayo olubanzi embonini. Lawa masu ahlanganisa i-electropolishing, sandblasting, pickling, laser welding, setting heat setting, forming, passivation, Af lokushisa ukuhlolwa, kanye nokuhlolwa kokukhathala, konke okuwukhiye wokulawula ukuthunyelwa kwe-Bredge. , “ngokuvamile kuxhomeke ekutheni sikhuluma ngokukhathala okukhulu noma ukukhathala okuncane.Isibonelo, ingxenye ekhathele kakhulu njengevalvu yenhliziyo ingase igoqe izikhathi eziyizigidi eziyinkulungwane ngesikhathi sokuphila kwayo njengokuyicubungula Njengesinyathelo, kubalulekile ukusebenzisa i-sandblasting ukuze kwandiswe i-radius yayo yonke imiphetho.Kodwa izingxenye ezikhathala kancane njengamasistimu okulethwa noma izintambo zokuqondisa ngokuvamile azidingi ukucutshungulwa okuningi ngemva kokucubungula.”Mayelana nobuchwepheshe bokuklama, u-Brenzel uyachaza, manje kunamakhasimende amaningi njengezingxenye ezintathu kwezine asebenzisa izinsizakalo zawo zokuklama ukuze asebenzise usizo lwe-NPX namakhono ekutholeni imvume ye-FDA.Inkampani inhle kakhulu ekuguquleni umqondo "we-napkin sketch" ube umkhiqizo ngendlela yawo yokugcina ngesikhathi esifushane.
I-Motion Dynamics (i-Fruitport, MI) ingumkhiqizi weziphethu ezincanyana ngokwezifiso, amakhoyili ezokwelapha nezintambo ezihlanganisiwe injongo yazo kuwukuxazulula izinkinga zamakhasimende, kungakhathaliseki ukuthi ziyinkimbinkimbi noma zibonakala zingenakwenzeka kangakanani, ngesikhathi esifushane ngangokunokwenzeka.
Njengoba kushiwo ngaphambili, ukukhethwa kwe-fiber noma i-USP laser kuyindaba yokuthandwa kobunjiniyela kanye nohlobo lwemishini nezinqubo ezisekelwayo.UChris Witham, uMongameli we-Motion Dynamics, wachaza: "Ngokusekelwe kumodeli yebhizinisi egxile kakhulu emikhiqizweni ye-neurovascular, singaletha imiphumela ehlukene ekuklanyeni, ekusebenzeni nasekusebenzeni.Sisebenzisa kuphela ukusika nge-laser ukukhiqiza izingxenye esizisebenzisa endlini., ukwenza izingxenye zenani eliphezulu, “ezinzima” eseziphenduke zaba okukhethekile nesithunzi sethu;asinikezi ukusika i-laser njengesevisi yenkontileka.Sithole ukuthi ukusika kwe-laser okuningi esikwenzayo kwenziwa kangcono kakhulu ngamalaser e-USP, futhi iminyaka eminingi bengisebenzisa i-StarCut Tube ngenye yalezi laser.Ngenxa yesidingo esinamandla semikhiqizo yethu, sinamashifu amabili angu-8 ngosuku, ngezinye izikhathi ngisho namashifu amathathu, futhi ngo-2019 sidinga ukuthola enye i-StarCut Tube ukuze sisekele lokhu Kukhula.Kodwa kulokhu, sinqume ukuhamba nenye yamamodeli amasha ayingxube ye-femtosecond USP lasers nama-fiber lasers.Siphinde sayibhangqa nesilayishi/isilayishi se-StarFeed ukuze sikwazi ukusika ngokuzenzakalelayo - opharetha umane abeke okungenalutho Ishubhu ilayishwa ekuphakeleni futhi uhlelo lokusebenza lwesofthiwe lomkhiqizo luyaqalwa.
Umfanekiso 3. Leli shubhu lokulethwa lensimbi engenasici elishintshashintshayo (eliboniswe eduze kwerabha lepensela) lisikwe nge-laser ye-Monaco femtosecond.
U-Witham uyanezela ukuthi nakuba ngezinye izikhathi besebenzisa umshini ekusikeni okuyisicaba, ngaphezu kwamaphesenti angu-95 esikhathi sabo basichitha bedala noma belungisa imikhiqizo eyisilinda yama-catheter ahlanganayo, okungukuthi ama-hypotubes, amakhoyili nama-spirals, okuhlanganisa amathiphu okusika amaphrofayili kanye nezimbobo zokusika. igolide, iplatinum ne-nitinol.
Umfanekiso 4. I-Motion Dynamics iphinde isebenzise i-laser welding kakhulu.Ngenhla, ikhoyili ishiselwe eshubhu lokusika i-laser.
Yiziphi izinketho ze-laser? U-Witham wachaza ukuthi ikhwalithi enhle kakhulu yonqenqema kanye nama-kerfs amancane abalulekile ezingxenyeni zawo eziningi, ngakho baqale bancamela amalaser e-USP. Ngaphezu kwalokho, azikho izinto inkampani ezisebenzisayo ezingasikwa ngenye yalawa ma-laser, okuhlanganisa nezingxenye zegolide ezincane ezisetshenziswa njengezimaka ze-radiopaque kweminye yemikhiqizo yayo. ukungabaza ukuthi i-fiber optics inganikeza isivinini esiphezulu," esho. "Kodwa ngenxa yokugxila kwethu kwesicelo esithile, lokhu ngokuvamile kusho uhlobo oluthile lokucubungula emva kokucubungula, njengokuhlanza kwamakhemikhali kanye ne-ultrasonic noma i-electropolishing.Ngakho ukuba nomshini oyingxubevange kusivumela ukuthi sikhethe ukuthi iyiphi inqubo iyonke - i-USP iyodwa noma i-fiber kanye nokubamba ngemuva kokucubungula - I-Optimum yengxenye ngayinye.Kusivumela ukuthi sihlole ukuthi kungenzeka yini ukwenziwa kwe-hybrid machining yengxenye efanayo, ikakhulukazi lapho kuhileleke ama-diameter amakhudlwana nokuqina kodonga: ngisho nokusika ngokushesha ngama-laser fiber, Bese usebenzisa i-laser ye-femtosecond ukuze usike kahle.”Ulindele ukuthi i-laser ye-USP izohlala iyisinqumo sabo sokuqala ngoba iningi lokusikeka kwe-laser yabo lihlanganisa ukujiya kodonga phakathi kuka-4 no-6 wena, nakuba behlangabezana nogqinsi olusuka ku-1-20 you.Amapayipi ensimbi engagqwali phakathi kwakho.
Sengiphetha, ukusika nokubhoboza nge-laser kuyizinqubo ezibalulekile ekwakhiweni kwemishini yezokwelapha ehlukahlukene.Namuhla, ngenxa yentuthuko yobuchwepheshe be-laser obuyisisekelo kanye nemishini eyenziwe kahle kakhulu ehlelelwe izidingo ezithile zemboni, lezi zinqubo kulula ukuzisebenzisa futhi zilethe imiphumela engcono kunangaphambili.
