Anthu akamva 'zigawo za zida zachipatala' nthawi zambiri amaganiza za zinthu zosabala, zonyezimira zomwe zili pagulu. Chowonadi ndi grittier. Ndi za kuponya komwe kumayenera kukhala kosasunthika kwazaka zambiri, kapena makina opangira makina omwe sangalephereke pambuyo pa kuzungulira zikwi khumi mu autoclave. Kusiyana pakati pa kujambula ndi gawo logwira ntchito ndipamene ntchito yeniyeni imachitika, ndipo ndipamene zaka zimathera.
Maziko: Zimayamba ndi Cast
Simungathe kupanga gawo labwino kuchokera pakuponya koyipa. Ndilo phunziro loyamba lolimba. Pazida zoyeserera kapena zida za radiation therapy gantry, kukhulupirika kwazinthu sikungakambirane. Tawona ma projekiti akuyimitsidwa chifukwa choyambirira kuponya ndalama anali ndi micro-porosity yomwe imangowonekera panthawi yomaliza. Mtengo wa nyumba zazitsulo zosapanga dzimbiri zomwe zatsala pang'ono kutha ndi mphunzitsi wankhanza.
Apa ndipamene zinachitikira foundry zimafuna kupambana. Kampani ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., ndi zaka makumi atatu mu zipolopolo ndi kupanga ndalama, amamvetsetsa kuti kutentha kwa kutsanulira cobalt-chromium alloy pa chida chopangira opaleshoni ndizosiyana kwambiri ndi chitsulo chosapanga dzimbiri. Sizimangokhudza kusungunuka kwachitsulo; ndizokhudza kuwongolera njira yolimba kuti mupewe zovuta zomwe zimakhala zolephera.
Chisankho pakati pa chipolopolo cha chipolopolo ndi kuponya ndalama kwa kuperekedwa zida zachipatala gawo nthawi zambiri zimabwera ku geometry ndi kumaliza kwapamwamba. Chigawo chovuta, chokhala ndi mipanda yopyapyala chapampu yamakina a dialysis? Mwina ndalama. Bulaketi yokulirapo ya bedi lachipatala? Chikopa cha zipolopolo chikhoza kukhala chopanda ndalama zambiri popanda kupereka nsembe. Chisankho sichimamveka bwino nthawi zonse, ndipo nthawi zina chimafunika kutengera njira zonse ziwiri.
Precision Machining: Kumene Kulekerera Kuluma Mmbuyo
CNC Machining mbali zachipatala amamva mosiyana. Pali kulemera m'maganizo. Kulekerera kwa ± 0.005mm pa bore si lingaliro; Ndi malire a chisindikizo chomwe chimakhudza madzi amthupi. Ndikukumbukira gulu la nyumba zolumikizira zowunikira odwala komwe tinali kuthamangitsa chowonadi cha 0.01mm. Makinawa anali okhoza, koma kukonza ndi kukulitsa kutentha kuchokera pakudula zitsulo zosapanga dzimbiri za 316L zidatiponya. Tidayenera kuwongolera kutentha komwe kuli m'sitolo molimba - zambiri osati pajambula.
Njira ya QSY ku CNC makina pazigawo zachipatala nthawi zambiri zimaphatikizapo kupereka mizere yamakina yamagulu ena azinthu. Kuthamanga kwa nickel-based alloys, komwe kumagwira ntchito ngati misala, pamakonzedwe omwewo monga chitsulo choponyera ndi njira yosinthira zida zamoyo ndi zovuta zomaliza. Kuzilekanitsa kungawoneke ngati kosagwira ntchito pamapepala, koma kumalepheretsa kuipitsidwa kwazinthu zakuthupi ndikusunga dongosolo lokhazikika. Kukhazikika kumeneko ndi komwe kumawalola kuti agunde Ra 0.8μm pamwamba nthawi zonse pamalumikizidwe onyamula katundu, zomwe ndizofunikira kwambiri popewa kuyambitsa ming'alu.
Kutsimikizika kwa post-machining ndi gawo lina. Si lipoti la CMM chabe. Pazigawo za ma implants kapena zida zolumikizirana kwanthawi yayitali, nthawi zambiri timatchula njira zowonjezera kapena njira zina zoyeretsera kuti tichotse tinthu tating'ono tating'ono tating'ono pamakina. Gawo likhoza kukhala langwiro koma lodana ndi biologically ngati sitepeyi yachitika mofulumira.
The Alloy Dilemma: Zofunika Si Nambala Yokha
Kutchula zitsulo zosapanga dzimbiri ndi zopanda tanthauzo. Ndi 304, 316L, kapena 17-4PH? Iliyonse imachita mosiyana panthawi yoponya ndi kukonza, ndipo aliyense amakhala ndi mawonekedwe osiyanasiyana okana dzimbiri m'malo azachipatala. 316L ndiye kavalo pazifukwa zomveka, koma pazigawo zomwe zimafunikira mphamvu zambiri, monga zoyendetsa fupa kapena zida zina za arthroscopic, timatsamira m'makalasi owumitsa mvula ngati 17-4PH kapena ma aloyi apadera.
Ma alloys opangidwa ndi cobalt ndi nickel ali mumgwirizano wawo. Amagwiritsidwa ntchito ngati mawondo opangira ma prosthetic kapena m'malo otentha kwambiri a autoclave racks. Kupanga kwawo kumakhala kovuta kwambiri—kuthamanga kocheperako, ma geometries a zida zapadera, kuzizira kosalekeza kowongolera kutentha. Ubwino wake ndi kuvala kwapadera komanso kukana dzimbiri. Mtengo wake ndi kugwiritsa ntchito zida komanso nthawi yayitali yozungulira. Ndawonapo mapulojekiti omwe kusintha kuchokera ku zosapanga dzimbiri kupita ku aloyi ya cobalt kuchulukitsa mtengo wopangira makina, koma inali njira yokhayo yokwaniritsira zofunikira pamoyo wazaka 15.
Kugwira ntchito ndi mnzanu yemwe ali ndi chidziwitso chakuya ndikofunika kwambiri. Sikuti kukhala ndi aloyi mu katundu; ndi kudziwa momwe kutentha-kuwachitira pambuyo Machining kukwaniritsa kuuma ankafuna popanda kuchititsa kupotoza, kapena mmene kupanga dongosolo gating kwa kuponyera kuonetsetsa yunifolomu njere dongosolo mu mawonekedwe ovuta.
Njira Zolephera ndi Chifukwa Chake
Aliyense amalankhula za njira zopambana, koma kusanthula zolephera ndizothandiza kwambiri. Tinali ndi mlandu wokhala ndi kabokosi kakang'ono ka actuator ka robot yochita opaleshoni. Idapambana macheke onse koma idalephera pakuyesa kutopa. Choyambitsa chake chinayambikanso ndikusiyana pang'ono kwapa chipolopolo nkhungu kuponyera ndondomeko-kusagwirizana pang'ono mu makulidwe a zipolopolo za ceramic kunapangitsa kusiyana kwa kuzizira komwe kumapangidwira, kupanga chigawo cha microstructure yosiyana pang'ono. Pansi pa maikulosikopu, zinkawoneka. Pansi pa katundu wa cyclic, inali malo ophwanyika.
Ichi ndichifukwa chake kuyang'anira ndondomeko kumafunika kwambiri kuposa kufufuza komaliza kwa zigawo zofunika kwambiri. Inu simungakhoze kuyendera khalidwe mu gawo; muyenera kumanga kuchokera pa sitepe yoyamba yopanga nkhungu. Otsatsa omwe amapeza izi, monga QSY ndikuyang'ana kwawo kwanthawi yayitali m'malo mongotulutsa, amakhala ndi zolephera zocheperako izi, kutsata m'mbuyo. Mbiri yawo yazaka 30 ikuwonetsa kuti adawonapo ndi kuthetsa mavuto amtunduwu m'mbuyomu.
Kulephera kwina kofala, kosawoneka bwino ndi galvanic corrosion pamisonkhano. Kugwiritsira ntchito wononga chitsulo chosapanga dzimbiri m'nyumba ya aluminiyamu pa mkono wopepuka wa sikani kungawoneke bwino, koma pamaso pa zinthu zina zoyeretsera, kumatha kukhazikitsa selo lowononga. Gawolo sililephera nthawi yomweyo; imalephera pakatha miyezi yogwiritsira ntchito, nthawi zambiri kunja kwa nthawi ya chitsimikizo. Kusanthula kwazinthu pakapangidwe kazinthu ndi chinthu chosakanjanitsika chomwe nthawi zambiri chimanyalanyazidwa.
The Realistic Partnership
Kugula zida zachipatala zida si mtengo wogulira. Ndi mgwirizano waukadaulo womwe umayamba kale RFQ isanachitike. Zotsatira zabwino kwambiri zimachitika pamene wopanga zida achita ndi mnzake wopanga pagawo la prototyping. Kodi ngodya yamkatiyi ingathe kuwongoleredwa pang'ono kuti ipititse patsogolo moyo wa zida popanda kusokoneza magwiridwe antchito? Kodi makulidwe a khomawa angapangidwe kukhala ofananirako kuti asamire muzoponya?
Othandizana nawo omwe ali ndi luso lophatikizika-kuchokera pakupanga mpaka CNC makina-amapereka malingaliro athunthu. Atha kulangiza kuti gawo lopangidwa ngati chowotcherera ndi makina litha kupangidwa modalirika ngati chopangira chimodzi chokhala ndi makina ochepa omaliza, kukonza kukhulupirika kwadongosolo ndikuchepetsa malo oipitsidwa. Kupanga kwamtundu woterewu ndikofunika kwambiri ndipo kumachokera ku zochitika zapagulu pazopanga zonse.
Pamapeto pake, cholinga chake ndi kudalirika m'munda. Gawolo si chinthu pa bilu ya zipangizo; ndi gawo la chipangizo chomwe dokotala amadalira. Malingaliro amenewo amasintha momwe mumayendera kulolerana kulikonse, kumaliza kulikonse kwapamwamba, ndi satifiketi iliyonse. Imasuntha ntchitoyo kuchoka ku zopanga zosavuta kupita ku zopereka zopangidwa mwaukadaulo. Ndipo izi, pamapeto pake, ndizomwe zimalekanitsa wogulitsa katundu ndi mnzake weniweni wopanga makampani azachipatala.
