Xa iinjineli zicacisa iinxalenye zeenkqubo ze-hydraulic okanye i-high-pressure pump assemblies, "i-precision steel casting factory" ayikho nje igama lokukhangela-yimfuno engenakuxoxisana. Uzinzo lweDimensional phantsi kwebhayisekile eshushu. Ingqibelelo yeMicrostructural emva kokunyangwa kobushushu. Isiphelo somphezulu esisindayo ukugeleza kwe-abrasive. Ezi ayizonyamezelo; ziintsika zokusilela. Siye sabona abathengi benqaba iibhetshi ezipheleleyo zemveliso kuba ukuphambuka kwe-0.015 mm kwi-piston pump cylinder yezindlu kubangele ukukhathala okubangelwa yi-cavitation kwi-3,200 psi. Yiyo loo nto ukukhangela kumzi-mveliso wesinyithi ochanekileyo ochanekileyo kuthetha ngaphezulu kwesatifikethi se-ISO-ifuna uqeqesho oluqinisekisiweyo lwe-metallurgical, in-process rigor metrology, kunye nokuqinisekiswa kokusebenza-hayi nje ukuthotyelwa komda.
Kutheni iCobalt-Nickel Alloys ichaza iBenchmark
Uninzi lweefektri ezichanekileyo zokuphosa intsimbi zibamba i-316 engenasici okanye i-ASTM A108 yensimbi yekhabhoni. Zimbalwa i-cobalt-nickel alloys enkosi-ingakumbi i-AMS 5387 kunye ne-T800-grade materials-apho ubulukhuni be-machining budlula i-HRC 45 kunye nokwandiswa kwe-thermal coefficients kufuna imbuyekezo ye-sub-micron casting shrinkage. Ekuhanjisweni kwehlabathi lokwenyani, siye saqaphela ukuba izindlu ezisemgangathweni zesanti ze-AMS 5387 zepompo ziyaqhekeka ngexesha le-nitriding ukuba ulwakhiwo lweenkozo alulawulwa kwi-ASTM E112 iNqanaba 7. Iqela lethu liqinisekisa yonke i-cobalt alloy egalelwe ngokuhlalutya kwe-spectrographic * phambi * kokuvala ukubunjwa-kunye ne-cross-check model ye-dendrite ye-arm spacing ngokuchasene ne-slid spacing. Oku akuyothiyori. Yiloo nto egcina imilomo ye-cobalt alloy isebenza iinyanga ezili-18 kwimithombo yokutofa kwerhasi emuncu ngaphandle kokhukuliseko.
Ukudityaniswa okuthe nkqo akusiyo i-Buzzword-Ngumgca wokuPhila oMda
Outsourcing casting, ke machining, ke unyango ubushushu kudala imithombo emithathu ezimeleyo yempazamo cumulative. Utshintsho olungundoqo oluyi-0.05 mm ekugalweni kwesanti luba yi-0.08 mm emva kokugaya i-CNC erhabaxa-kunye ne-0.12 mm emva kokunciphisa uxinzelelo-ngaphandle kokuba zonke iinkqubo zihlala phantsi kophahla olunye kunye neereferensi zedatha ekwabelwana ngayo. Kwiziko lethu le-Qingdao, i-CMM efanayo iqinisekisa ijometri, imilinganiselo yokugqiba kwangaphambili, kunye neefowuni zokugqibela ze-GD&T zisebenzisa ukulinganisa ukulinganisa okufanayo kunye nokulungiswa kobushushu obuzinzile. Silinganise ukuya kuthi ga kwi-40% yokunyamezelana okungqongqo kwi-winch ye-winch centre shaft rollers xa umatshini wenziwa kwii-castings zisafudumele ukusuka ku-shakeout-kuba imemori ye-thermal kwi-microstructure inciphisa ukusebenza kwakhona. Kukudityaniswa okuthe nkqo kuzisa uzinzo olunokulinganiswa-hayi irhetoric yokuthengisa.
Ulawulo Lomgangatho Ophendula Imibuzo Yokwenene—Hayi Ludwe Kuphela Lokutshekisha
“Uyihlolile?” ngumbuzo ongalunganga. Ezona zichanekileyo zezi: *Ngowuphi umaleko wolusu lokuphosa oye waqinisekiswa ukuze ubandakanywe umxholo? Ngaba umphezulu wabhore obaluleke kakhulu uskenwe kwi-pitch ye-0.1 mm-okanye isampuliwe nje ngamanqaku ama-5? Ngaba ilog yakho yokulandelelwa ibandakanya eyona nombolo yomjikelo wedire yebhetshi ephethwe ubushushu?* Iprothokholi yethu yokuhlola iphendula zontathu. Yonke ivalve yoxinzelelo ifumana i-metallografi yecandelo elipheleleyo kumphezulu wokutywina. Yonke into yokuphosa intsimbi engenasici iye kuvavanyo lwangoku lwe-eddy ephindwe kabini kwi-subsurface porosity-hayi nje ukungena kwedayi. Kwaye ewe-sigcina iicerts zezinto eziluhlaza, iitshathi zokuphatha ukushisa, kunye neengxelo ze-CMM ze-10 iminyaka. Ngenxa yokuba xa isiseko sempompo sihluleka kwiiyure ze-12,000, "silandele inkqubo" ayiqalisi ukuvelisa kwakhona. Ukulandeleka okupheleleyo kwenza.
Ukukhetha Umzi-mveliso Wakho Wesinyithi ochanekileyo-Yeyona nto ihambisa inaliti
Jonga iincwadana ezinemifanekiso. Buza ubungqina bezinto ezintathu: Okokuqala, ubungqina be-in-house capability ye-alloy yakho ethile-isicelo seengxelo zovavanyo lwebakala lakho elichanekileyo (umzekelo, i-T800, kungekhona "i-cobalt-based"). Okwesibini, buza ukuba baqinisekisa njani ukuzinza kwe-dimensional *emva* kokugqiba-ngaba balinganisa kwi-20°C, 25°C, kunye ne-30°C ukumisela i-real-world thermal drift? Okwesithathu, qinisekisa ukuba ngaba uphononongo lwabo lwe-GD & T lubandakanya ukulinganisa okusebenzayo-kungekhona nje ukunyamezela ukunyamezela. Sakhe sanceda i-OEM yaseYurophu ukunciphisa ukuvuza kwevalvu ngama-68% ngokuhlengahlengisa i-engile eyidrafti yokuphosa ukuze ikwazi ukulungiselela i-post-machining springback kwiringi yesihlalo. Olo lwazi luvela ekuqhubeni i-FEA kwijometri ye-as-cast-hayi kuluhlu lokujonga umzobo. Ukuchaneka akuchazwa ngokufunda ngemicrometer. Ichazwa ngendlela esebenza ngayo inxalenye xa ifakiwe, icinezelwe, kwaye ijikeleziswa. Khetha iqabane elilinganisa zombini.
