Masiku ano, pafupifupi onse mwatsatanetsatane kudula laser zitsulo ndi sanali zitsulo ntchito zida okonzeka ndi CHIKWANGWANI lasers kapena ultrashort pulse (USP) lasers, kapena nthawi zina onse awiri.M'nkhani ino, tifotokoza ubwino osiyana lasers awiri ndi kuona mmene opanga onse ntchito lasers izi.NPX Medical (Plymouth, MN) ndi mgwirizano wapadera zipangizo pokonza zipangizo, kupanga zipangizo zosiyanasiyana steplonts, kupanga ndi deploma ndi machubu osinthasintha, pogwiritsa ntchito makina omwe amaphatikizapo fiber lasers.Motion Dynamics imapanga magulu akuluakulu, monga "kukoka waya" misonkhano yomwe imagwiritsidwa ntchito makamaka mu ubongo, pogwiritsa ntchito makina omwe amaphatikizapo USP femtosecond laser ndi imodzi mwa machitidwe atsopano osakanizidwa kuphatikizapo femtosecond ndi fiber lasers kuti athe kusinthasintha kwakukulu ndi Versa kusinthasintha.
Kwa zaka zambiri, laser micromachining yambiri yakhala ikugwiritsidwa ntchito pogwiritsa ntchito ma lasers olimba a state nanosecond otchedwa DPSS lasers. kamangidwe ndi molunjika mphamvu scalability.This zotsatira lasers kuti ndi yaying'ono, odalirika kwambiri, ndi zosavuta kaphatikizidwe mu makina apadera, ndipo zambiri kupereka mtengo wotsika umwini kuposa akale laser types.Importantly kwa micromachining, mtengo linanena bungwe akhoza lolunjika mu ang'onoang'ono, woyera malo a ma microns ochepa m'mimba mwake, kotero iwo ndi abwino kwa obowola mkulu-reso ndi flexical kudula kwambiri. kuwongolera, ndi kugunda kwamphamvu kuyambira kuwombera kumodzi mpaka 170 kHz. Pamodzi ndi mphamvu yowopsa, izi zimathandizira kudula ndi kubowola mwachangu.
Komabe, kuipa kwa fiber lasers mu micromachining ndiko kupanga zinthu zing'onozing'ono ndi/kapena zoonda, zosalimba. Kutalika (mwachitsanzo, 50 µs) kugunda kwa nthawi kumapangitsa kuti pakhale kutentha pang'ono komwe kumakhudzidwa (HAZ) monga recast zinthu ndi roughness yaing'ono, yomwe ingafunike post-processing. femtosecond output pulses-kuthetsa vuto la HAZ.
Ndi ma USP lasers, kutentha kwakukulu komwe kumakhudzana ndi kudula kapena kubowola kumatengedwa mu zinyalala zotayidwa musanakhale ndi nthawi yofalikira muzinthu zozungulira.USP lasers yokhala ndi picosecond linanena bungwe lakhala likugwiritsidwa ntchito mu micromachining ntchito zokhudzana ndi mapulasitiki, semiconductors, ceramics, ndi zitsulo zina (picoseconds = 10-2 zitsulo zachitsulo, koma zitsulo zachiwiri za picosecond 2). Kutentha kwazitsulo kwazitsulo komanso kukula kochepa kumatanthauza kuti ma lasers a picosecond nthawi zonse samapereka zotsatira zowongoka zomwe zingalungamitse mtengo wowonjezereka wa ma laser a USP. zikutanthauza kuti amatha kudula kapena kubowola zitsulo zonse zomwe zimagwiritsidwa ntchito pazida zamankhwala, kuphatikizapo zitsulo zosapanga dzimbiri, platinamu, golide, magnesium, cobalt-chromium, titaniyamu, titaniyamu, ndi zina zambiri, komanso zopanda zitsulo.
Inde, pafupifupi palibe m'makampani athu omwe amafunikira laser imodzi yokha.M'malo mwake, amafunikira makina opangidwa ndi laser, ndipo tsopano pali makina ambiri apadera omwe amakongoletsedwa ndi kudula ndi kubowola zipangizo zamankhwala.Chitsanzo ndi Coherent's StarCut Tube series, yomwe ingagwiritsidwe ntchito ndi lasers fiber, femtosecond lasers, kapena ngati mtundu wosakanizidwa womwe umaphatikizapo mitundu yonse ya laser.
Kodi luso lazachipatala limatanthauza chiyani?Zambiri mwa zipangizozi zimapangidwa m'magulu ochepa malinga ndi mapangidwe achikhalidwe.Choncho, kusinthasintha ndi kugwiritsira ntchito mosavuta ndizofunika kwambiri.Ngakhale kuti zipangizo zambiri zimapangidwa kuchokera ku billets, zigawo zina ziyenera kukhala zolondola kuchokera ku mapepala apamwamba; makina omwewo ayenera kugwira zonse ziwiri kuti awonjezere mtengo wake.Zosowa izi nthawi zambiri zimakumana ndi kupereka maulendo angapo a CNC olamulidwa (xyz ndi rotary) ndi HMI yosavuta kugwiritsa ntchito pulogalamu yophweka ndi kulamulira.Pankhani ya StarCut Tube, njira yatsopano yotsegulira chubu imabwera ndi magazini yotsegula pambali (yotchedwa StarFeed) ya machubu mpaka 3 m kutalika kwa mankhwala odulidwa, kupanga makina opangidwa ndi makina opangidwa ndi automa.
The ndondomeko kusinthasintha kwa makinawa ndi zina kumatheka ndi thandizo kwa chonyowa ndi youma kudula ndi mosavuta chosinthika nozzles yobereka kwa njira amafuna kuthandiza gas.Spatial kusamvana ndi yofunikanso makamaka machining mbali yaing'ono kwambiri, kutanthauza kuti kukhazikika thermomechanical kumathetsa zotsatira za kugwedezeka nthawi zambiri amakumana mu masitolo makina.The StarCut Tube osiyanasiyana amakwaniritsa chosowa ichi ndi kumanga chiwerengero chachikulu cha granite deck.
NPX Medical ndi wopanga mgwirizano watsopano wopereka mapangidwe, uinjiniya ndi ntchito zodulira zolondola za laser kwa opanga zida zamankhwala. Yakhazikitsidwa mu 2019, kampaniyo yapanga mbiri pamsika wazinthu zabwino kwambiri komanso kuyankha, kuthandizira zida zosiyanasiyana kuphatikiza ma stents, implants, ma valve stents ndi machubu osinthika operekera njira zosiyanasiyana zopangira opaleshoni, ma spinal cardiac, interpedic, spinal interpedic, interpedic, spine Laser cutter yake yayikulu ndi StarCut Tube 2 + 2Â yokhala ndi StarFiber 320FC yokhala ndi mphamvu pafupifupi 200 watts.Mike Brenzel, m'modzi mwa omwe adayambitsa NPX, adalongosola kuti "oyambitsa amabweretsa zaka za kapangidwe ka zida zamankhwala ndi luso lopanga - zoposa zaka 90 zokhala ndi makina amtundu wa StarC" Ntchitoyi ikuphatikizapo kudula kwa Nitinol ndipo tikudziwa kale kuti ma lasers amatha kupereka liwiro ndi khalidwe lomwe timafunikira. Pazida monga machubu ozungulira-mipanda ndi ma valve a mtima, timafunika kuthamanga, ndipo laser ya USP ikhoza kukhala yodekha kwambiri pa zosowa zathu. pambuyo pokonza ndi kuyendera, poyerekeza ndi masabata pambuyo poyitanitsa makampani akuluakulu.
Chithunzi 2. NPX imapereka njira zosiyanasiyana zotsatiridwa pambuyo pokonza.Zinthu zomwe zikuwonetsedwa apa ndi T316 zitsulo zosapanga dzimbiri ndi 5mm OD ndi makulidwe a khoma la 0.254mm. Mbali yakumanzere imadulidwa / microblasted ndipo mbali yoyenera ndi electropolished.
Kuphatikiza pa mbali za nitinol, kampaniyo imagwiritsanso ntchito kwambiri cobalt-chromium alloys, tantalum alloys, titaniyamu ndi mitundu yambiri yazitsulo zosapanga dzimbiri. Jeff Hansen, Laser Processing Manager, akufotokoza kuti: "Kusinthasintha kwa makina ndi chinthu china chofunika kwambiri, chomwe chimatilola kuthandizira kudula kwa mitundu yosiyanasiyana ya zipangizo, kuphatikizapo chubu ndi pulasitiki. Ena mwa machubu awa ndi 0.012 ″ ID, ndipo kuchuluka kwamphamvu kwamphamvu yamagetsi aposachedwa kumakulitsa liwiro lathu lodulira pomwe timapereka m'mphepete momwe timafunikira.
Kuphatikiza pa kudula mwatsatanetsatane komanso kuyankha mwachangu, NPX imaperekanso umisiri wathunthu wokonza pambuyo pokonza, komanso ntchito zopangira zambiri zomwe zimathandizira luso lake pantchitoyi. Njirazi zimaphatikizapo electropolishing, sandblasting, pickling, laser kuwotcherera, kutentha, kupanga, passivation, kuyezetsa kutentha kwa Af, ndi kuyezetsa kutopa, zonse zomwe ndizofunika kwambiri pakuwongolera zida za NiUtinol. kumaliza, Brenzel adati, "kawirikawiri zimadalira ngati tikukamba za kutopa kwakukulu kapena kutopa kwambiri. Mwachitsanzo, mbali yotopa kwambiri ngati valve yamtima imatha kupindika nthawi biliyoni imodzi pa moyo wake wonse ngati kukonzanso monga sitepe, ndikofunika kugwiritsa ntchito sandblasting kuti muwonjezere utali wa mbali zonse. Pankhani ya luso la mapangidwe, Brenzel akufotokoza kuti, tsopano pali ochuluka monga magawo atatu mwa atatu a makasitomala amagwiritsanso ntchito ntchito zawo zojambula kuti apindule ndi thandizo la NPX ndi luso lopeza chilolezo cha FDA. Kampaniyi ndi yabwino kwambiri potembenuza lingaliro la "chopukutira" kukhala mankhwala mu mawonekedwe ake omaliza mu nthawi yochepa.
Motion Dynamics (Fruitport, MI) ndi opanga akasupe ang'onoang'ono, ma koyilo azachipatala ndi mawaya omwe cholinga chake ndikuthana ndi mavuto a makasitomala, ngakhale atakhala ovuta bwanji kapena akuwoneka ngati zosatheka, munthawi yaifupi yotheka. misonkhano.
Monga tanena kale, kusankha kwa fiber kapena USP laser ndi nkhani ya uinjiniya wokonda komanso mtundu wa zida ndi njira zomwe zimathandizidwa. Chris Witham, Purezidenti wa Motion Dynamics, adalongosola kuti: "Kutengera mtundu wa bizinesi womwe umayang'ana kwambiri pazamankhwala a neurovascular, titha kupereka zotsatira zosiyanitsidwa pamapangidwe, kachitidwe ndi ntchito. Timangogwiritsa ntchito laser kudula kuti tipange zida zomwe timagwiritsa ntchito m'nyumba, zomwe zimakhala zovuta kwambiri kupanga "zovuta kwambiri". Sitikupereka laser kudula ngati ntchito ya mgwirizano Tapeza kuti mabala ambiri a laser omwe timachita amapangidwa bwino ndi ma lasers a USP, ndipo kwa zaka zambiri ndakhala ndikugwiritsa ntchito StarCut Tube ndi imodzi mwama lasers awa, timakhala ndi masinthidwe awiri a maola 8 patsiku, nthawi zina ngakhale masinthidwe atatu, ndipo mu 2019 timafunikira thandizo lina imodzi mwamitundu yatsopano yosakanizidwa ya femtosecond USP lasers ndi fiber lasers Tidayiphatikizanso ndi chojambulira / chotsitsa cha StarFeed kuti titha kupanga makinawo - wogwiritsa ntchito amangoyika opanda kanthu Chubu chimayikidwa mu feeder ndipo pulogalamu yogwiritsira ntchito pulogalamuyo imayamba.
Chithunzi 3. Chubu choperekera zitsulo zosapanga dzimbiri (chowonetsedwa pafupi ndi chofufutira cha pensulo) chadulidwa ndi laser ya Monaco femtosecond.
Witham akuwonjezera kuti ngakhale nthawi zina amagwiritsa ntchito makinawo kudula lathyathyathya, kuposa 95 peresenti ya nthawi yawo amathera kupanga kapena kusintha zinthu zozungulira pamisonkhano yawo ya catheter yowongoka, yomwe ndi ma hypotubes, ma coils ndi ma spirals, kuphatikiza nsonga zodulira mbiri ndi Dulani mabowo. chitsulo chosapanga dzimbiri, golide weniweni, platinamu ndi nitinol.
Chithunzi 4. Motion Dynamics imagwiritsanso ntchito kuwotcherera kwa laser kwambiri.Pamwambapa, koyiloyo yalumikizidwa ku chubu chodulidwa cha laser.
Kodi njira za laser ndi ziti?Witham adalongosola kuti mtundu wabwino kwambiri wam'mphepete ndi ma kerfs ochepa ndizofunikira kwambiri pazinthu zawo zambiri, kotero poyambirira adakonda ma laser a USP.Kuonjezera apo, palibe zida zomwe kampaniyo imagwiritsa ntchito zitha kudulidwa ndi imodzi mwa ma lasers awa, kuphatikiza tinthu tating'ono tagolide tomwe timagwiritsa ntchito ngati zolembera za radiopaque muzinthu zina zake. "N'zosakayikitsa kuti CHIKWANGWANI Optics angapereke liwilo apamwamba," iye anati. "Koma chifukwa cha makamaka ntchito yathu cholinga, izi kawirikawiri amatanthauza mtundu wina wa pambuyo processing, monga mankhwala ndi akupanga kuyeretsa kapena electropolishing. Choncho kukhala ndi makina wosakanizidwa amatilola kusankha zonse ndondomeko - USP yekha kapena CHIKWANGWANI ndi post-processing Kusamalira - Optimum kwa aliyense chigawo chimodzi. Imatilola ife kufufuza m'mimba mwake wa hybrids omwewo, makamaka m'mimba mwake wa ma hybrids omwewo. komanso makulidwe a khoma amakhudzidwa: ngakhale kudula mwachangu ndi ma lasers, Kenako gwiritsani ntchito femtosecond laser kudula bwino. Akuyembekeza kuti laser ya USP ikhalabe chisankho chawo choyamba chifukwa kudula kwawo kwa laser kumakhudza makulidwe a khoma pakati pa 4 ndi 6 iwe, ngakhale amakumana ndi makulidwe a khoma kuyambira 1-20 iwe. Mipope yachitsulo chosapanga dzimbiri pakati pa inu.
Pomaliza, laser kudula ndi pobowola ndi njira kiyi popanga zipangizo zosiyanasiyana zachipatala.Today, chifukwa cha kupita patsogolo mu luso laser pachimake ndi makina kwambiri wokometsedwa kukhazikitsidwa kwa zosowa zenizeni za makampani, njira zimenezi n'zosavuta kugwiritsa ntchito ndi kupereka zotsatira zabwino kuposa kale.
