Pamene mainjiniya ku North America kapena ku Europe amafunikira a China CNC mwatsatanetsatane Machining fakitale okhoza kupirira ± 0.005 mm pampopi ya cobalt-nickel - poyang'aniridwa ndi ISO - samangofufuza "wopereka CNC ku China." Amasaka *kuthekera kotsimikizirika*, osati malonjezo amndandanda.
Tawona ma projekiti ambiri akuyimitsidwa chifukwa sitoloyo idavomereza zojambulazo koma inalibe chidziwitso ndi machitidwe owumitsa ntchito a AMS 5387 panthawi ya mphero zambiri. Kapena choyipirapo: kuvomereza magawo a aloyi a T800 popanda kutsimikizira malipoti azitsulo kuchokera kwa ogulitsa ovomerezeka. Kulondola kwenikweni sikutanthauza kanthu ngati kukhulupirika kwa microstructure kulephera pansi pa 300-bar hydraulic cycling. Ichi ndichifukwa chake kudalirika kogwira ntchito - osati kungotsatira kwa GD&T - kumalekanitsa chowonadi China CNC mwatsatanetsatane Machining fakitale kuchokera ku malo ogulitsa ntchito wamba.
Kulondola kwenikweni kwapadziko lapansi kumayamba ndi kuwongolera zinthu - osati kungotengera makina
Ma aloyi opangidwa ndi cobalt ngati T800 ndi AMS 5387 "samapangidwa" - amakopeka. Kutentha kwawo ndi 1/10th ya aluminiyamu. Kusamutsidwa kwa chip sikulephereka ngati kuchuluka kwa chakudya kumatsika ndi 3%. Kutentha kamodzi kosatsimikiziridwa kumatha kusintha kuuma ndi 15 HRC - yokwanira kuphwanya mpando wamphuno pakuyesa kukakamiza.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amaona zinthu zopangira ngati sitepe yoyamba - osati bokosi logulira. Billet iliyonse ya cobalt-nickel imakhala ndi ziphaso zonse za mphero, zotsimikiziridwa pofika motsutsana ndi ASTM A494 ndi AMS 5719. Gulu lawo laukadaulo limayenereza wopereka aliyense, kuwunika zipika za ng'anjo ndi malipoti a spectrographic - osati ma invoice okha. Izi si overkill. Ndimomwe amaperekera zokolola zoyambira 99.2% pamapampu a AMS 5387, ngakhale makulidwe a khoma atsika pansi pa 2.3 mm.
Kuphatikizika kwawo kwa makina opanga makina kumalimbitsa kuwongolera komwe ena akutaya. Maziko a mpope achitsulo oponyedwa pamchenga amafika atakonzedwa kale mpaka ± 0.1 mm rough stock - kuchotsa zolakwika zokonzanso. Mabotolo a cobalt oyika ndalama amapita molunjika mu 5-axis CNC kwa mizere yomaliza, kulumpha chithandizo chachiwiri cha kutentha chomwe chimapotoza ma geometrium okhala ndi mipanda yopyapyala. Kuphatikizika koyima sikukhudza kupulumutsa mtengo. Ndiko kutseka kukhazikika kwa dimensional kudutsa matenthedwe.
Kuyendera si chipata chomaliza - kumangiriridwa mumayendedwe aliwonse
Mashopu ambiri amayendetsa macheke a CMM atapanga makina. QINGDAO QIANGSENYUAN amayendetsa *panthawi* - pakati pa roughing ndi kumaliza kudutsa. Chifukwa chiyani? Chifukwa chida cha 0.012 mm chimavala chosinthira pa pisitoni pampu ya silinda yanyumba kusintha kumakhala kopitilira malire. Ma profilometers awo amayezera kumapeto kwa *in situ*, kukana mbali zoziziritsa kukhosi zisanachotse umboni wa kung'ambika pang'ono.
Chigawo chilichonse chofunikira chimatha kutsatiridwa bwino: nambala ya kutentha, ID ya wogwiritsa ntchito, ID ya makina, sitampu ya lipoti la CMM, ndi chizindikiro chomaliza chotsutsana ndi zomwe kasitomala amavomereza - osati "ISO 2768". Bungwe la European OEM litapempha kuti zitsimikizidwe kuti cholozera cha shaft chosakhazikika cha winch chili ndi katundu wofananira, gululo lidapanga jig yoyeserera ndikupereka ma curve-deformation curves pambali pa zomwe zidatumizidwa. Palibe mawu owonjezera. Osachedwetsa. Kungolinganiza mainjiniya.
Kupanga-zopanga-zopanga sikungogulitsa - ndiye kuchepetsa chiopsezo chanu choyamba
"Mungathe kuchita izi?" ndi funso lolakwika. Cholondola ndi: "Chingalephereke chiyani poyamba - geometry, zinthu, kapena unyolo wamachitidwe?"
Mainjiniya a QINGDAO QIANGSENYUAN amatulutsa nkhani asanadule zitsulo. Amayitana mikangano ya GD&T pomwe kulolerana kwamalo kumasemphana ndi ma angles opangira. Adzawonetsa kusintha kwakung'ono kwa ma radius pa pulagi ya cobalt kuti apewe ming'alu yaying'ono yoyambitsa macheza. Amakana zojambula zokhala ndi mawonekedwe osawoneka bwino pamabowo amkati - kenako amapangira njira ina yotheka yokhala ndi zolembedwa zanthawi yozungulira.
Izi siziri kulakwitsa. Ndimomwe amadula nthawi ya NPI (zoyambitsa zatsopano) ndi 37% pamisonkhano yama hydraulic valve. Ndemanga zoyambilira zimalepheretsa $ 12,000 m'matumba a T800 ochotsedwa - ndi milungu itatu yokonzanso.
Kuyang'ana m'tsogolo, kuyang'ana kwawo kwa R&D sikuli pamakina akulu. Zili panjira zosakanizidwa: zopangira ndalama zofananira ndi ukonde zokhala ndi njira zozizirira zophatikizika, zomalizidwa ndi mphero yazakudya zomwe zimateteza kupsinjika kotsalira. API 6A ndi PED 2014/68/EU - osati ngati mabokosi, koma monga zopinga za mapangidwe awo.
Ngati gawo lanu lotsatira lolekerera kwambiri liyenera kupulumuka chifukwa chopanikizika kwambiri, kuvala kwambiri, kapena kuchita dzimbiri - ndipo muyenera China CNC mwatsatanetsatane Machining fakitale zomwe zimagwiritsa ntchito zitsulo mozama ngati makina - yambani ndi kufufuza zinthu, osati ma MOQ okha. Funsani umboni wowunika momwe ntchito ikuyendera - osati malipoti omaliza okha. Sankhani anzanu omwe amalankhula chilankhulo chanu: kuchuluka kwa mafunde, moyo wozungulira, kulephera - osati ma microns ndi ma Ra.
Kulondola kwenikweni sikuyezedwa kumapeto kwa mzere. Zimapangidwa muzosankha zilizonse - kuyambira pakusankha kutentha kwambiri mpaka njira ya zida. Ndiko kumene mainjiniya amakumana ndi kuphedwa.
