Lapho onjiniyela becacisa a Casting service factory, abagcini ngoku-oda izingxenye zensimbi-bazibophezela ekuzinzeni kobukhulu ngaphansi kwengcindezi ye-hydraulic yamabha angu-300, ubuqotho be-microstructure ngemva kokuhamba ngebhayisikili eshisayo, kanye nokungabekezeleli i-porosity emibhobho ye-cobalt-alloy. Kungakho imikhakha ebaluleke kakhulu—ama-OEM esistimu ye-hydraulic, izihlanganisi zephampu yasogwini, abakhi bezimoto ezisindayo—zingaveli ezisekelweni ezijwayelekile. Ziya lapho ukusakaza kungahlukaniswanga khona nokwenza imishini, lapho ukulandeleka kwezinto kuqala enombolweni yokushisa, nalapho i-GD&T ingabuyekezwanga ngemva kokukhiqiza—yakhelwe endleleni yamathuluzi yokuqala.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza lolu hlelo lokusebenza. Itholakala e-Qingdao, isitshalo sayo esithobela i-ISO siphatha kokubili utshalomali kanye nokusakazwa kwesihlabathi—kodwa kuphela izingxenye ezifuna ukunemba kwangemuva kokusakazwa: izindlu zesilinda sephampu ye-piston ezino-±0.015 mm bore concentricity, amavalvu okucindezela adinga ukuqinisekiswa okugcwele kwe-ASME B16.34 hydrotest, noma ama-winch center shaft rollers akhiwe ngomshini we-T800 oqinile we-T8000 HRC. Lokhu akukhona ukulingisa inqwaba. Ukukhiqiza okusebenzayo: ingxenye ngayinye iphethe amajika okwelapha ukushisa abhaliwe, imibiko ye-CMM ngedamu ngayinye ebalulekile, kanye nesitifiketi esiphelele sezinto ezibonakalayo ezivela kubahlinzeki abaqinisekisiwe.
Iningi labathengi alibukeli phansi ukuthi ingakanani ikhwalithi yokulingisa incike kulokho okwenzekayo *ngaphambi* kokuthela. Kwa-QINGDAO QIANGSENYUAN, ukusebenzisana kwe-metallurgical kuqala ekubuyekezweni komklamo. Lapho ikhasimende lithumela umdwebo wezindlu zephampu ye-cobalt AMS 5387 cobalt 6, onjiniyela ababheki nje ukujiya kodonga. Baqinisekisa ukwakheka kwesango ngokumelene nokulingiswa kokuqinisa, baqinisekisa izibonelelo zokuncipha zokupholisa okuqondisayo, futhi baqinisekise usayizi wokusanhlamvu wempahla eluhlaza ngokumelene ne-ASTM E112. Sibone amaphrojekthi amathathu ehluleka ekuhlolweni kwenkambu-hhayi ngenxa yephutha lomshini, kodwa ngenxa yokuthi i-Foundry yasekuqaleni isebenzisa isitokwe se-cobalt-nickel esingeyona i-vacuum-ncibilike. Imithombo ye-QINGDAO QIANGSENYUAN kuphela amabhilidi ancibilikisiwe we-vacuum-arc (i-VAR) noma i-vacuum-induction melted (VIM), enezitifiketi ezifana nakho konke ukushisa nomaka wesiriyeli wengxenye yokugcina.
Ukuhlanganiswa okuqondile yilapho ukuthembeka kuba nokulinganiswa. Ukufakwa kwensimbi kungase kudlule ku-NDT—kodwa uma umshini we-CNC wethula ingcindezi eyinsalela eshintsha izindawo ze-GD&T ngesikhathi sokuhamba ngamabhayisikili ashisayo, ingxenye iyehluleka ukusebenza. I-QINGDAO QIANGSENYUAN ilawula zombili izigaba ngaphansi kophahla olulodwa: ukulingisa kuya ngqo ezikhungweni zemishini ze-axis eziningi ezifakwe ukuhlola okungaphakathi kwenqubo, bese kushisisa imigqa yokwelapha ngamalogi esithandweni esilinganisiwe, bese kuya eziteshini zokulinganisa ezibonakalayo eziqinisekisa indawo yangempela phakathi kuka-0.008 mm. Awekho ama-handoffs. Azikho izikhala zedatha. Iqembu elilodwa liphethe lonke iketango—kusuka kukhemistri yensimbi encibilikisiwe ukuya ekugcineni kwendawo ephezulu engu-Ra ≤0.8 µm ezindaweni ezivaliwe. Amakhasimende ahlala ecaphuna lokhu njengokuhluka kwawo okuphezulu: lapho i-valve yokucindezela ivuza kubha engu-280, azi kahle ukuthi iyiphi ipharamitha yenqubo okufanele ihlolwe—hhayi ukuthi yimuphi umthengisi okufanele asole.
Ukulethwa komhlaba wangempela kuncike kokuningi kunomthamo. Kuya ngokuthi impendulo yokwenziwa kwangaphambi kwesikhathi ifika kanjani. Sike saba nama-OEM asebenza ngomshini waseNyakatho Melika ehlisa isikhathi-kuya-kumfanekiso ngo-40% ngenxa yokuthi i-QINGDAO QIANGSENYUAN imake i-undercut engakwazi umshini kusichasiselo se-GD&T *ngaphambi kokuba* kuqale* ukwakhiwa kwamathuluzi esikhunta—futhi iphakamise isibuyekezo esilungele ukulingisa esigcina ukugeleza kwamandla. Lokho akusekeli. Ubambiswano lobunjiniyela. Abaphathi bephrojekthi yabo bakhuluma kahle i-GD&T, bahumushe ama-callouts e-ASME Y14.5 ngaphandle kokuhumusha, kanye nezingozi zefulegi njengokuthi “Le engeli yokusalungiswa izobamba isihlabathi kumgogodla—ncoma ukuthi ubuncane obungu-3°.” Kubathengi abahlola i-a Casting service factory, lelo zinga lokushelela kwezobuchwepheshe okushumekiwe lihlukanisa abathengisi abathumela izingxenye kulabo abathumela izixazululo. Isinyathelo esilandelayo asicaphuni—sithumela umdwebo wakho womhlangano wephampu oyinkimbinkimbi ukuze uthole ukubuyekezwa kokwenziwa kwamahhala.
