Kusema sera kwa ntchito za fakitale yotaya sera sikungokhudza mawonekedwe-ndiko kumasulira koyamba kwakuthupi kwa cholinga chogwira ntchito kukhala chowonadi chopangidwa. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., tajambula mitundu yopitilira 12,000 ya sera kuyambira 2018-iliyonse ikugwiritsa ntchito zida zopangira ma hydraulic pressure valves, nyumba zapampu za cobalt-alloy, ndi zodzigudubuza za winch center shaft zomwe zimagwira ntchito pansi pa mipiringidzo 350 ndi 450 ° C. Chomwe chimalekanitsa mawonekedwe otheka kuchokera ku zinyalala zamtengo wapatali sikuti ndi kukhulupirika kwapang'onopang'ono, koma kukhazikika kwamafuta, machitidwe otulutsa pamwamba, komanso kugwirizana ndi machitidwe a zipolopolo za ceramic. Tinaphunzira izi movutirapo: gulu limodzi la AMS 5387 cobalt alloy nozzles linalephera kumamatira kwa chipolopolo panthawi ya dewaxing-osati chifukwa cha chitsulo, koma chifukwa sera yojambula yoyambirira inaphwa 0,32% kuposa momwe inafotokozera panthawi ya autoclaving.
Chifukwa Chimene Kusema Magwiridwe A sera Kumakakamiza Kutaya Zokolola - Osati Geometry Yokha
Mafakitale ambiri amaona sera yosema ngati njira yochitira nkhungu. Timachitenga ngati njira yosinthira. Pachiyambi chathu chogwirizana ndi ISO, phula lililonse limapangidwa ndi masitepe atatu ovomerezeka asanatulutsidwe: mawonekedwe a kutentha kwapakati (kuyezedwa pa 25°C → 65°C → 100°C), kuyezetsa kulimba kwa mawonekedwe a zipolopolo motsutsana ndi slurry yathu ya zircon-silica, ndi mapu a CNC toolpath compensation. Chifukwa chiyani? Chifukwa kupatuka kwa 0.15 mm mu geometry ya sera kumakhala 0.22 mm chitsulo chosapanga dzimbiri chomaliza pambuyo pochepera, kutentha kutentha, ndi kugaya - ndipo izi zimaposa ma callout a GD&T pa nyumba za silinda pampu ya piston ndi 37%. Timagwiritsa ntchito mabanja awiri a sera oyambira: otsika kwambiri (58-62 ° C) kuti azitha kuzizira mkati mwa mapulagi a aloyi a T800, ndi ma microcrystalline blends amphamvu kwambiri (72-76 ° C) pamagawo akulu akulu odzigudubuza a injiniya pomwe kuwongolera kumalepheretsa kupotoza panthawi yoviika.
Njira Zinayi Zolephereka Padziko Lonse-ndi Momwe Timazipewa
Kusema sera kwa ntchito zotayika za fakitale yoponyera sera kumalephera mwakachetechete mpaka chigobacho ching'ambika kapena kuponyera kusokonezedwa. Kutengera kusanthula kwazomwe zimayambitsa 217 ku North America ndi kubweza kwamakasitomala a EU, izi ndi zomwe zimasweka:
- Kutentha kwamphamvu kwa hysteresis: Sera itatenthedwanso pambuyo polimba pang'ono imapanga ma microfractures. Timalamula kusungunuka kwapang'onopang'ono komanso kuwongolera kutentha - palibe "kusungunulanso" kololedwa.
- Kusungirako tack pamwamba: Chotsalira cha stearic acid pachimake chimalepheretsa ngakhale kupaka utoto. Sera zathu zili ndi ≤0.8% yamafuta acids aulere; Magulu omwe akubwera amatsimikiziridwa kudzera pa FTIR spectroscopy.
- CNC chida kupatukaSera: Sera yofewa imapatuka pansi pa 12,000 RPM kumapeto kwa mphero, zomwe zimapangitsa kuti masitepe asokonezeke mumizere yozungulira. Timatenthetsa midadada isanakwane 18°C ±1°C tisanapange makina—otsimikiziridwa ndi ma thermocouples ophatikizidwa.
- Dimensional kusuntha panthawi ya msonkhano: Zolumikizira sera zogulitsira pamanja zimakula mwachangu kuposa zida za makolo. Tinasinthira ku kuwotcherera kwa akupanga pamisonkhano yonse yokhala ndi magawo angapo-kuchepetsa kusiyanasiyana kolumikizana kuchokera ku ± 0.13 mm mpaka ± 0.04 mm.
Izi sizongoganizira chabe. Amalowetsedwa mu database yathu yosagwirizana ndi zithunzi, malipoti a CMM, ndi magawo azitsulo - omwe amapezeka kwa makasitomala oyenerera akafunsidwa.
Momwe Kuphatikizika Koyima Kumasinthira Sera kukhala Chitsulo Choloseredwa
Ogulitsa ambiri amagulitsa sera wosema. Ochepa amalamulira zomwe zimachitika atachoka pa mphero ya CNC. Ku QINGDAO QIANGSENYUAN, mainjiniya omwewo omwe amakonza makina osema sera nawonso amayika chipolopolo chamoto, kuyang'anira kutsanulira kothandizidwa ndi vacuum, ndikutsimikizira kuuma komaliza pagawo lomaliza la faifi tambala. Kupitilira uku kumachotsa mipata ya handoff. Mwachitsanzo: kasitomala akapempha kuti pampu ya AMS 5387 ikhale yozungulira kwambiri, tidasintha kachulukidwe wa sera (kuchokera pa 0.91 g/cm³ kufika pa 0.93 g/cm³), tidasintha mawonekedwe a nthunzi, ndikuwonjezera kutentha kwa chipolopolo ndi mphindi 18—zonse pakupanga kamodzi. Zotsatira: kuzungulira kunakula kuchokera ku 0.082 mm mpaka 0.031 mm popanda kusintha aloyi yachitsulo kapena chithandizo cha kutentha.
Izi zimangogwira ntchito chifukwa malo athu amatha kuponya, makina amitundu yambiri, ndikumaliza pansi pa denga limodzi. Palibe wopereka sera wakunja yemwe angasinthe mawonekedwe ake kuti agwirizane ndi zipolopolo zanu, kuchuluka kwa ng'anjo yamoto, kapena njira yogayira pambuyo poponyedwa. Kuwongolera kumeneko kumachitika munthawi yeniyeni-ndi data.
Kusankha Carving Wax Ndikusankha Wothandizira Wanu Wopeza
Ngati mukuyang'ana sera yosema kuti mugwiritse ntchito fakitale yotayika ya sera yomwe ikuphatikizapo cobalt alloys, ma hydraulics othamanga kwambiri, kapena misonkhano yapampopi yofunikira kwambiri, funsani mafunso awa musanapereke lamulo:
- Kodi angapereke mapindikidwe otenthetsera omwe amayezedwa pagawo lanu lenileni la geometry-osati mipiringidzo yoyeserera?
- Kodi amatsimikizira kulimba kwa mawonekedwe a sera-to-chipolopolo pogwiritsa ntchito mawonekedwe anu a slurry ndi dip parameters?
- Kodi mapulogalamu awo a CNC amakometsedwa chifukwa cha kuuma kwanu kwa sera - kapena amadalira malaibulale amtundu wa G-code?
- Kodi atha kutsata chipika chilichonse ku malo ake, mbiri ya kutentha, ndi chipika cha makina?
Timayankha kuti inde kwa onse anayi. Osati monga zonena zamalonda - koma monga zoyang'anira zomangidwa mumayendedwe athu apamwamba a AS9100. Chilichonse chonyamula sera chimaphatikizapo satifiketi ya digito yokhala ndi zokutira za CMM, ma graph amtundu wamafuta, ndi zotsatira zoyesa zomatira. Chifukwa pakuponyera kolondola kwa mafakitale, sera si chiyambi. Ndilo gawo loyamba loyendera.
Kuti mugwirizane ndi luso pakusema sera pakuphatikizana kwa fakitale yotayika -makamaka ma aloyi a cobalt-nickel, matupi othamanga kwambiri, kapena zida zapampu zomwe sizili wamba - pitani https://www.tsingtaocnc.com. Timathandizira kutsimikizira zojambula, kutanthauzira kwa GD&T, ndi mayankho akupanga - phula loyamba lisanakwezedwe.
