Yang'anani, mukamva 'Co 6', ngati simuli ozama pakupanga kapena kupanga ma alloys ochita bwino kwambiri, mutha kungoganiza za kalasi ya cobalt. Koma ndi pamene msampha woyamba uli. Sizinthu zakuthupi zokha; ndi chizindikiro cha zovuta zonse ndi zisankho pansi pa shopu. Ndawonapo zojambula zambiri zikubwera ndi 'Co 6' chabe kapena mawu ofanana, ndipo funso lotsatira kuchokera ku gulu lathu lokonzekera nthawi zonse limakhala, Chabwino, koma kodi tikuchita chiyani pano? Zomwe zimapangidwira ndi chinthu chimodzi-aliyense akhoza kuyang'ana kuti ndi aloyi yochokera ku cobalt, nthawi zambiri imakhala ndi chromium yofunikira ndi tungsten yovala ndi kukana dzimbiri. Chowonadi chochikonza, kutulutsa mawu popanda ming'alu yaying'ono, kapenanso kupeza billet yosasinthika? Ndiye 'Co 6' weniweni. Imayimira gulu lomwe chikalata chaukadaulo chimakumana ndi zochitika, zomwe nthawi zambiri zimakhala zosokoneza, kupanga magawo omwe samalephera kutentha kwambiri kapena kuyabwa.
The Spec Sheet vs. The Lathe
Tinali ndi polojekiti kanthawi kumbuyo, gawo la valve la ntchito yovuta. Chisindikizocho chinafotokoza a cobalt-based alloy kukumana ndi Co 6 general properties. Makasitomala adapereka pepala la data, manambala onse osayembekezeka. Kusuntha kwathu koyamba ku Mtengo wa QSY sanali kukonza CNC; kunali kuyendetsa kagulu kakang'ono ka ma makuponi oyesera kuchokera kuzinthu zomwe zachokera. Chifukwa chiyani? Chifukwa machinability mlingo pa pepala pafupifupi wopanda tanthauzo. Muyenera kumva. Tinayamba ndi zoikamo wamba carbide aloyi kutentha kwambiri. Chotsatira? Kutsetsereka m'mphepete mwachangu, kutha kwapamtunda kosagwirizana, ndi kutentha kochulukirapo kuposa momwe timakondera. The Ko 6 chuma, ndi chizoloŵezi chake choumitsa ntchito, chinali kubwezera. Tsambalo silinalankhule za kusinthika pang'ono kwa batch muzinthu za tungsten, zomwe zidangopangitsa kuti ntchito yovuta ikhale yovuta.
Apa ndipamene zaka 30 zakusewera ndi makina zimayambira. Mumayamba kumva m'matumbo. Tinasinthira ku njira yankhanza kwambiri yokhala ndi zida zapadera, zakuthwa zakuthwa za ceramic mothamanga kwambiri koma kutsika kocheperako. Zikumveka zotsutsana-zachilengedwe-zoumba pa cobalt? Koma zinali zokhudzana ndi kuyang'anira malo otentha ndikuletsa zinthu kuti zisaumire patsogolo pa chida. Mawerengedwe a chakudya ndi liwiro kuchokera ku mapulogalamu anali poyambira, koma magawo omaliza amachokera ku phokoso la kudula ndi mtundu wa chip. Ziphuphuzi ziyenera kukhala zasiliva, osati zabuluu. Buluu amatanthauza kusungirako kutentha kwambiri, kuyika chiwopsezo chazitsulo zazitsulo pansi pa gawolo. Ndi cheke chowoneka komanso chomveka cha QA kuti palibe makina odzichitira okha omwe angalowe m'malo.
Mbali yoponyera ya ma aloyi oterowo, omwe timawagwiritsa ntchito kudzera munjira yathu yopangira ndalama, imakhala ndi chithunzi chosiyana. Ndi ma aloyi opangidwa ndi cobalt, kuchuluka kwa kulimbitsa ndi kusinthasintha kwa kutentha ndizofunikira kwambiri. Thirani ozizira kwambiri, mumapeza mistruns. Kuthira kotentha kwambiri, kumalimbikitsa kukula kwakukulu kwa njere. Pachinthu chovuta, chokhala ndi mipanda yopyapyala chomwe tidachita chaka chatha, tidayenera kupanga njira yolowera ndi kukwera yomwe sinali m'buku lililonse. Zinatengera zolephera zam'mbuyomu - tidawona shrinkage porosity ikusonkhana pamphambano inayake. Yankho linaphatikizapo kuyika kosakhazikika kozizira kuti kulimbikitsa kulimba. Zinagwira ntchito, koma zinawonjezera ndalama ndi nthawi. Ndiwo msonkho wobisika wogwira ntchito ndi zipangizo monga Ko 6. Mtengo wake suli muzitsulo zosaphika pa kilogalamu; zili m'chidziwitso chosonkhanitsidwa cha momwe angachiumbire modalirika.
Sourcing ndi Consistency Gambit
Tiye tikambirane za zopangira. Simungangoyitanitsa 'Co 6' kuchokera pamphero ndikuyembekeza kufanana. Kusiyana pakati pa zosungunula, ngakhale kuchokera kwa ogulitsa odziwika, kungakhale kokwanira kutaya makina anu onse. Tinaphunzira izi movutikira kale. Tinayenerera njira yopangira mphete yosindikizira kuchokera kumagulu enaake a bar. Zidutswa 100 zoyambirira zinali zangwiro. Gulu lotsatira, lochokera ku nambala yosiyana ya zinthu 'zomwezi', linayamba kupangitsa kuti kuphatikizika kuchuluke katatu. Ziwonetsero za moyo wa zida zidatuluka pawindo. Wolakwa? Tsatirani zinthu, zomwe mwina ngati tantalum kapena kaboni zomwe zili m'mphepete mwa malire, zomwe zimasintha machitidwe a alloy pansi pa kumeta ubweya wa chida.
Tsopano, machitidwe athu okhazikika, makamaka pazigawo zofunika kwambiri, ndikuumirira pa chiphaso cha kusanthula kwa gawo linalake ndikuyesa kuyesa kwathu kwa spark kapena, chabwinoko, kuyang'ana mwachangu ngati voliyumu ikuvomereza. Ndi sitepe yowonjezera yomwe makasitomala ena amadandaula nayo, koma imapulumutsa mutu waukulu kumunsi kwa mtsinje. Ichi ndi gawo lalikulu la kudalirika Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd. malonjezo. Sizokongola, koma kuwongolera zolowetsa ndi 50% yopambana pankhondoyi ndi ma superalloys. Nthawi zina timakhala ndi mashopu ang'onoang'ono, apadera osungunula omwe amathandizira gawo lazamlengalenga chifukwa kuwongolera kwawo kumakhala kolimba, ngakhale nthawi yotsogolera italikirapo. Kwa muyezo cobalt aloyi pampu gawo, kusungunuka kwa kalasi yamalonda kungakhale bwino. Kwa chowongolera tsamba la turbine, sichiwuluka.
Kusagwirizana kumeneku kumatulutsanso magazi mu njira yoponyera. The fluidity ya chitsulo chosungunuka, chomwe chimakhudza momwe chimadzazira zovuta chipolopolo nkhungu, akhoza kusiyana. Kusungunula komwe kumatuluka pang'onopang'ono pawindo lake la kutentha kungayambitse kutsekedwa kozizira kapena zowonongeka zomwe zimakhala zovuta kupeza ndi kukonza pambuyo poponya. Tasamukira kukuyang'anira nthawi yeniyeni panthawi yothira - ma pyrometer, makamera oyerekeza otenthetsera pa kapu yothira - kuti tigwire zokhota izi zikachitika. Sizopanda nzeru, koma zimatembenuza zidutswa za batch kukhala zowongolera, zowongolera pang'ono.
Kuwotcherera ndi Kukonza Conundrum
Nayi zochitika zomwe sizimapeza nthawi yokwanira yolumikizirana: kukonza. Makasitomala amatumiza chotopa Ko 6 chigawo chimodzi, mwina kubowola pang'ono bushing kapena mbale kuvala. Kodi mungamange malo owonongekawo ndikuwongoleranso? Yankho lamabuku ndi inde, ma aloyi a cobalt nthawi zambiri amatha kuwotcherera. Yankho lenileni la dziko ndiloti, Zimatengera, ndipo ndizowopsa. Malo okhudzidwa ndi kutentha (HAZ) kuchokera ku kuwotcherera amatha kupanga thumba lazinthu zomwe zimakhala zosiyana kwambiri-zigawo zowonongeka, zowonongeka zimatha kupanga. Tinayesa izi pamakina ena ovala makina aulimi, pogwiritsa ntchito zofananira cobalt-based alloy waya wodzaza ndi njira yolondola ya TIG.
Zotsatira zoyambirira zidawoneka bwino. Mkanda wa weld unali womveka. Koma pakadutsa njira yopangira makina kuti ibwererenso kukula, ming'alu yaying'ono imafalitsidwa kuchokera ku HAZ. Gawolo linali lopanda pake. Kodi tikuphunzirapo chiyani? Pakukonza kowona kwa zigawo zopsinjika kwambiri, kuwotcherera nthawi zambiri kumakhala komaliza. Nthawi zina, zimakhala zotsika mtengo kungoponya ndikusindikiza gawo latsopano kuyambira poyambira. Pazinthu zosafunikira kwenikweni, mutha kuthawa, koma muyenera kukhazikitsa dongosolo la preheat ndi post-heat (PWHT), lomwe limawonjezera mtengo ndi zovuta. Tsopano tili ndi chisankho chosavuta: mtengo wa gawo latsopano vs. mtengo wokonza + chiopsezo cholephera muutumiki. Nthawi zambiri, ndi zida pamlingo uwu, kuponya kwatsopano kumapambana.
Izi zikugwirizananso ndi gawo la mapangidwe. Tikamakambirana ndi makasitomala pakupanga siteji, ngati tiwona chigawo chokonzekera a cobalt aloyi monga Co 6, nthawi zambiri timakankhira mapangidwe omwe ndi osavuta kuyika pachidutswa chimodzi ndi makina bwino, m'malo mwa mapangidwe omwe angafunike kusonkhanitsa kapena kukonza zowotcherera mtsogolo. Ndi kusintha kosaoneka bwino kuchoka kungokhala wopanga kukhala bwenzi lopanga zinthu. Zimawapulumutsa ku zovuta komanso mtengo wopitilira moyo wa gawolo.
Beyond the Metal: The Real Cost Driver
Pomaliza, lingaliro lolakwika lalikulu ndikungoyang'ana pamtengo wa kilogalamu imodzi ya Ko 6 aloyi. Mtengo wachitsulo ndi wofunikira, inde, koma nthawi zambiri siwoyendetsa wamkulu. Mtengo weniweni uli pakupanga zokolola komanso kugwiritsa ntchito zida. Kuchuluka kwa 10% pa aluminiyamu ndi chinthu chimodzi. Chiwopsezo cha 10% pa cobalt alloy ndi vuto lazachuma. Gawo lililonse-kuchokera ku kuponya ndalama ndondomeko yomwe chipolopolo chimawononga gulu, kupita ku makina a CNC pomwe kuyika kwa $ 150 kumatenga magawo atatu m'malo mwa 10 - kumakulitsa kutayika.
Timatsata zomwe zimatchedwa 'cost per good part' mwachipembedzo pantchitozi. Zimakhudza chilichonse: zinthu, mtengo wa nkhungu, nthawi yopangira makina, zida, kuyendera, ndi zotsalira zomwe zikuyembekezeka. Kukonzekera kwa metric iyi ndi komwe kumalekanitsa masitolo omwe amalowa mu superalloy ndi omwe amakhalapo. Kwa ife, zingatanthauze kuyika ndalama pang'onopang'ono, molondola kwambiri waya-EDM pazinthu zina m'malo moyesera mphero, kungotsimikizira kuti palibe chida chosokoneza kapena zovuta ntchito. Zitha kutanthauza kupanga zosintha zomwe zimachepetsa kugwedezeka panthawi yamphero, chifukwa macheza pa a cobalt aloyi pamwamba akhoza kuyambitsa kutopa ming'alu.
Zotengera? Pamene mukuyang'ana wothandizira pazinthu zomwe zikukhudza Ko 6 kapena azisuweni ake, osangofunsa ma cert awo. Funsani za zokolola zawo zamitundu yofananira. Funsani za njira zawo zopangira zida komanso moyo wa zida zomwe akuyembekezeka. Funsani ngati anafunikapo kupulumutsa gulu kudzera mu kuwotcherera kapena HIP (Hot Isostatic Pressing) ndi zotsatira zake. Mayankho awo adzakuuzani zambiri za kuthekera kwawo kuposa kabuku konyezimira. Ndi muzambiri izi, zosasangalatsa, ukadaulo weniweni wokhala ndi zida ngati izi umakhala, mtundu womwe unamangidwa kwazaka zambiri, monga maziko pa. Mtengo wa QSY, pomwe phunziroli limakhala nthawi zonse: lemekezani zomwe mwalemba, funsani zomwe mwasankha, ndipo khulupirirani njira yomwe mwakulitsa pakuyesa ndipo, nthawi zina, zolakwika.
