Pamene mainjiniya afotokoza Investment kuponyera magawo fakitale ntchito zama hydraulic valves, pump housings, kapena ma winch shafts, sikuti amangogula zitsulo-akugula kukhazikika kwapakati pa 300-bar pressure, microstructure integrity pambuyo pa chithandizo cha kutentha, ndi zero kulolerana kwa porosity mu cobalt-nickel alloy nozzles. Tawona mapulojekiti ambiri akuyimitsidwa chifukwa wogulitsa adalonjeza "kuponyedwa mwatsatanetsatane" koma adapereka magawo omwe adalephera kutsimikizika kwa CMM pomaliza kuyendera - makamaka pazigawo za AMS 5387 kapena T800-grade pomwe kuuma kolimba ndi njira yoyendera mbewu imakhudza mwachindunji moyo wotopa.
Chifukwa Chake Kuponya Ndalama Sizinali Njira Inanso—Ndi Cholepheretsa Kachitidwe
Kuponyera ndalama kumapambana pomwe kuponya mchenga kumasokonekera ndipo makina a CNC amadutsa malire. Koma kupambana kumayamba kalekale ndondomeko ya sera isanasungunuke. Pamalo athu ku Qingdao, kuyitanitsa kulikonse kumayamba ndikusunga zitseko zazitsulo: ma cert aiwisi amatsimikiziridwa * asanayambe * alloying, osati ataponya. Timakana magulu okhala ndi kupatuka kwa 0.02% mu chromium kapena molybdenum pazitsulo zokhala ndi cobalt - chifukwa malirewo amasankha ngati pulagi ya AMS 5387 ipulumuka matenthedwe 12,000 pamapampu am'mphepete mwa nyanja.
Tayesa kuchuluka kwa kutentha kwa 47 kutentha kwazitsulo zosapanga dzimbiri - ndipo tidapeza kuti kusinthasintha sikungochitika mwachisawawa. Imalondola molunjika ndi mapangidwe a gating, chinyezi chowumitsa zipolopolo, komanso liwiro la preheat ramp. Ndichifukwa chake mapepala athu amatsekera magawo 19 - osati "kutsanulira kutentha" ndi "nthawi yozizira." Mwachitsanzo, pisitoni pampu yamphamvu nyumba amafuna olamulira okhazikika kulimba kupewa centerline microporosity. Kusiyana kwa kuzizira kwa 1.2°C/mphindi kumasintha mtunda wa mikono wa dendrite ndi 8.6 µm. Ndizo zoyezeka. Ndizotheka kuchita.
Kuphatikizika Koyima Kumathetsa Zowawa Zenizeni-Osati Zongotsatsa Zotsatsa
Otsatsa ena amapangira makina akunja, chithandizo cha kutentha, kapena kumaliza pamwamba. Izo zimaphwanya kuyankha. Pamene kuthamanga valavu nyumba mokhota pambuyo-kutentha mankhwala, ndi makina mlandu caster; casteryo anaimba mlandu wogulitsa ng'anjo. Tili ndi masitepe onse atatu. Maselo athu a CNC amayendera limodzi ndi mizere yoponyera-kotero gawo loponyedwa pa 8 koloko ndi lokhazikika, lopangidwa mwankhanza, lochepetsetsa kupsinjika, lomalizidwa, ndipo CMM imafufuzidwa ndi 4 koloko masana. Wothandizira yemweyo. Zolemba za calibration zomwezo. ID yofananira yofananira.
Izi sizothandiza - ndikuwongolera koyendetsedwa ndi fizikisi. Kupanga makina akadali okhazikika kumapewa kukonzanso kupsinjika kotsalira. Tachepetsa mitengo ya zinyalala ndi 63% pamaziko a pampu yachitsulo chosapanga dzimbiri posintha kutembenuza komaliza kuti kuchitike mkati mwa maola anayi kuchokera pakuyatsa. Ndipo inde - timalemba kutentha ndi chinyezi pagulu lililonse. Chifukwa ma swing 5 ° C amasintha mavalidwe a zida pazitsulo zolimba za T800 ndi 17%.
Zomwe Makasitomala Amayesa (ndi Chifukwa Chake Amalepherera Ena)
Ogula samafunsa "Kodi mumapanga ndalama?" Amafunsa kuti: "Kodi mungagwire ± 0.015 mm pa 320-mm-diameter yokhala ndi mapeto a 3.2 µm Ra, pogwiritsa ntchito cobalt alloy, ndi kupereka ma cert athunthu kuphatikiza malipoti a CMM pa ASME Y14.5?" Izi ndi zomwe zimalekanitsa kukwaniritsidwa ndi malonjezo:
- Kutsimikizika kwa GD&T kumachitika zida zisanayambe—osati pambuyo pa nkhani yoyamba. Timayimitsa mikangano ya data, kulolerana kwambiri kosagwirizana ndi makulidwe a zipolopolo, kapena ma radii othina kwambiri kuti asamayendetse matope a ceramic.
- Palibe "standard" kutentha kutentha. Timasintha nthawi yonyowa potengera makulidwe a gawo-osati zolemba zamakalata. Khoma la 45-mm limafuna 2.3 × kutalika kuposa khoma la 12-mm kuti lifanane ndi kutentha kudutsa gawo lonselo.
- Gawo lililonse lofunikira limatsimikiziranso ziwiri: CMM ya geometry, comparator kuwala kwa matanthauzo a m'mphepete - chifukwa kutalika kwa burr kumafunika pa malo osindikizira.
Takhala ndi makasitomala akusintha pakati pa pulojekiti atazindikira kuti omwe adawagulitsa kale adagwiritsa ntchito ziphaso za "zitsulo zosapanga dzimbiri" m'malo mwa malipoti enieni a kutentha. Timasindikiza satifiketi iliyonse ndi ID ya ng'anjo, nambala yothira, ndi malo oyesa kuponi. Palibe kuchotserapo.
Kumene Kulondola Kumakwaniritsa Zochita—Tsopano ndi Kenako
An Investment kuponyera magawo fakitale imapeza chidaliro osati kudzera m'mabulosha—koma kudzera mmene imachitira ndi kusamvera koyambirira. Kota yatha, European hydraulics OEM idatitumizira chojambula chokhala ndi ma callout osagwirizana a GD&T pagulu la valve. M'malo mongonena mwachimbulimbuli, tidapanga mapu a ntchitoyo, tidapanga njira ziwiri zopangidwira, ndikuyendetsa FEA pawiri kuti tiwonetse kusiyana kogawa kupsinjika. Anasankha Njira B—ndipo anadula nthawi ya msonkhano ndi 22%.
Kuyang'ana m'tsogolo, tikukulitsa kukonzekera kwa ISO 13485 pazigawo zachipatala za cobalt ndikutsimikizira ma hybrid casting-machining workflows kwa onyamula ma turbine vane vane. Koma chofunika kwambiri masiku ano sichinasinthe: kupereka magawo omwe amayesa kuyesa-osati macheke ang'onoang'ono. Ngati pulojekiti yanu yotsatira ikufunika ma valve oponderezedwa, ma silinda, kapena zida zamtundu wa cobalt zomangidwira kuti zitha kunyamula zinthu zenizeni padziko lapansi, yambani ndi kufufuza zinthu, osati mawu otsatsa.
