Pamene nyumba ya hydraulic pump ikulephera pa 3,000 psi-kapena cobalt alloy nozzle imasweka pansi pa njinga yamoto-choyambitsa sichimapangidwira kawirikawiri. Ndi mphamvu ya fakitale yowongoka bwino kwambiri: kuthekera kogwira ± 2 µm kulolerana pazinthu zolimba za AMS 5387 ndikusunga umphumphu wapamtunda kudzera pakuchiritsa kutentha ndikumaliza. Kuwongolera kumeneku sikumatuluka m'masitolo a CNC. Imakhala m'malo omangidwa ndi cholinga chimodzi: kutembenuza zovuta za alloy kukhala zobwerezabwereza, zofunikira kwambiri.
Chifukwa chiyani "Kulondola Kwakung'ono" Sikuti Kungotsatsa-Ndi Kuchita Zoyezera
Makina enieni olondola kwambiri amapitilira manambala olimba pachojambula. Ndiko kubwerezabwereza kwa kugunda 0.0001 ″ (2.5 µm) kulolerana kwapamalo pazigawo 500 zopangidwa kuchokera ku T800 cobalt-based superalloy —zinthu zomwe zimawuma pakamakina, kupotoza zida, ndi kufuna kubweza nthawi yeniyeni. Tawona makasitomala akusintha ogulitsa pambuyo poti nyumba zambiri zapampu za pistoni zalephera. Nthawi iliyonse, vuto silinali kutanthauzira kwa GD&T-kunali kosagwirizana ndi kasamalidwe ka matenthedwe pamilling yamitundu yambiri. Gawolo lidadutsa macheke a CMM kutentha kwachipinda koma kugwedezeka ndi ntchito. Kumeneko sikulephera kwa QA. Ndi kusiyana kwa ndondomeko.
Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., kulondola pang'ono kumatanthauza kuyika metrology mumayendedwe -osati pakuwunika komaliza. Mabilu a cobalt-nickel omwe akubwera amawunikiridwa mwachiwonekere asanachitike. Macheke omwe akugwiritsidwa ntchito amagwiritsa ntchito makina ojambulira owoneka bwino pamalo osindikizira - osati ma probe a CMM okha. Kutsimikizira komaliza kogwira ntchito kumaphatikizapo kuyesa kukakamiza kwa matupi a valve osonkhanitsidwa pa 1.5 × ovotera kukakamiza kogwira ntchito. Izi sizowonjezera-injiniya. Ndimomwe mumapewa kulephera kwamafuta ndi zida zogwetsera gasi pomwe mtengo wosinthira umaposa $200,000 pa ola lopuma.
Maluso Anayi Omwe Amalekanitsa Kusamalitsa Kwakukulu Kuchokera ku Standard Machining
Mafakitale ambiri amati "kulekerera kwakukulu." Ndi ochepa omwe amazipereka nthawi zonse m'magawo anayi omwe amadalirana:
- Kukhoza kwakuthupi: Osati kungopeza AMS 5387 kapena T800-koma kutsimikizira kusasinthika kwazitsulo zamagulu ndi batch ndi ma protocol othandizira kutentha. Pulagi yosakhazikika ya kasitomala m'modzi imafunika 42 HRC yochepa *pambuyo* pomaliza. Kuchita kwanthawi zonse kungachepetse kuuma ndi mfundo zisanu. Yankho lathu? Kuchepetsa kupsinjika kusanachitike + kuziziritsa koyendetsedwa pakati pazovuta ndi zomaliza.
- Kuwongolera kwa hybrid process: Kuponyera mchenga kutsatiridwa ndi 5-axis CNC si zachilendo. Koma kukhala ndi makulidwe a khoma la ± 0.02 mm pachitsulo chachitsulo cha 120-mm-diameter * musanapange * makina - kenako kukwaniritsa ± 0.005 mm pamabowo opangidwa ndi makina - kumafuna maziko olumikizana ndi kukonza makina ogulitsa makina. Timayendetsa zonse pansi pa denga limodzi logwirizana ndi ISO.
- GD&T kuphedwa, osati kungowerenga: Chojambula chikatchula Datum B ngati malo oponyedwa ndi zosintha za MMC, sitiganiza zofananira. Timayika ma geometry ngati-cast, kenako timasintha njira za zida - kuti mbali yomaliza igwirizane ndi malo okwererako, osati zolemba zongoyerekeza.
- Kutsata komwe kuli kofunikira: Valavu iliyonse yokakamiza imakhala ndi tag yokhala ndi QR yolumikizana ndi satifiketi yake yakuthupi, chipika chothandizira kutentha, lipoti la CMM, ndi chithunzi chomaliza choyendera. Osati kwa zisudzo zotsata malamulo - chifukwa cholozera cha winch center shaft chikalephera pa zombo zapanyanja zaku Norway, mainjiniya amayenera kudzipatula ngati vutolo linali kutulutsa tirigu kapena kuchepetsa kupsinjika kwapambuyo pa makina.
Mtengo wa "Zabwino Zokwanira" mu Mapulogalamu Ochita Bwino Kwambiri
Ogula ena amasankha kusankha fakitale ya micro precision Machining ngati ntchito yodula. Amafanizira mawu a pampu yachitsulo chosapanga dzimbiri ndikusankha mtengo wotsika kwambiri. Kenako amakumana ndi kukonzanso: kutayikira kwa gasket pa bar 250, zolemba zojambulidwa molakwika zomwe zimapangitsa kuti zisindikizo zisamakwane, kapena kuzimitsa kosakonzekera panthawi yotumiza. Masamu akusintha mwachangu. Gawo la $ 1,200 lomwe limachedwetsa kuyambika ndi maola 48 limawononga ndalama zoposa $2,800 zomwe zimaperekedwa panthawi yake-ndizowoneka bwino komanso zitsulo.
Tatsata mapulojekiti 17 pazaka ziwiri pomwe mgwirizano woyambirira wa uinjiniya udachepetsa ndalama zonse ndi 19-33%. Bwanji? Potchula zoopsa zomwe zingapangidwe * musanagwiritse ntchito: kuwonetsa pang'ono pojambula pamphuno ya cobalt alloy kuti athetse EDM kumaliza, kapena kusintha fillet radius kuti mupewe macheza m'nyumba yopyapyala yokhala ndi mipanda yopyapyala. Izi sizikugwirizana. Iwo ndi zisudzo zopangitsa kulondola.
Zomwe Muyenera Kufuna Pafakitale Yanu Yotsatira ya Micro Precision Machining
Osafunsa "Kodi mumachita molondola pang'ono?" Funsani m'malo mwake:
- "Ndiwonetseni malipoti anu atatu omaliza a CMM a magawo opangidwa kuchokera ku AMS 5387, makamaka kuchuluka kwa zozungulira komanso kukhazikika pamabowo amkati."
- "Mumatsimikizira bwanji kukhazikika kwa chitsulo cha 300-mm-utali musanayambe kukonza komaliza?"
- "Kodi kutalika kwanu kosagwirizana ndi kotani kuti mutembenuze shaft ya T800 ya 12-mm-diameter-ndi 150 mm kuchokera ku chuck ndi chiyani?"
Ngati mayankho sakumveka bwino kapena atumizidwa ku "dipatimenti yathu yabwino," chokanipo. Kuthekera kwenikweni kwa fakitale ya micro precision machining kumawonekera mu manambala olembedwa, obwerezabwereza—osati mabulosha.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito pomwe kulondola kwa dimensional kumakwaniritsa zotsatira zake. Mphamvu zake sizili pakuchita chilichonse-koma pakuchita zinthu zovuta kwambiri, mosasinthasintha: milomo ya aloyi ya cobalt, nyumba zomangira ma silinda a pampu, ma valve opondereza, ndi ma shaft a ma winchi omwe amagwira ntchito mopanikizika, kuzungulira pambuyo pa kuzungulira. Kwa mainjiniya omwe amatchula magawo omwe kusintha kwa µm kumakhudza chitetezo, nthawi yokwera, kapena moyo wonse, kuyang'ana kumeneku sikungasankhe. Ndi njira yokhayo yotsimikizira kudalirika kwa fakitale ya micro precision Machining.
