Lapho onjiniyela becacisa ingxenye okufanele ikwazi ukusinda ku-30,000 psi hydraulic pressure, imelane nokugwavuma ezindaweni ezinodaka olubi, noma igcine ukuqina kohlangothi ngemva kwamahora angu-500 ku-650°C—“okwanele” akuyona inketho. Kungakho ama-OEM omhlaba ku-hydraulics, uwoyela negesi, kanye nemishini yeselula esindayo ehlala ephendukela ekubeni OEM CNC imishini ifektri ngobungcweti obufakazelwe be-cobalt-nickel superalloys, hhayi nje izitolo zensimbi ezihloselwe jikelele.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ungomunye wabalingani abanjalo. Isekelwe e-Qingdao, e-China, inkampani ayikuthathi ukunemba njengokuqedwa—iyakha kulo lonke ungqimba: ukuthola izinto ezibonakalayo, ukwakheka okusanhlamvu okusanhlamvu, isu lendlela yamathuluzi enama-eksisi amaningi, isikhathi sokucwiliswa kokushiswa kokushisa, kanye nokuhambisana ne-GD&T eqinisekiswe yi-CMM. Sibone amakhasimende eshintsha abahlinzeki ngemva kokuhluleka kwezindlu zabo zephampu ze-AMS 5387 ezintathu ezihlulekile—iphimbo ngalinye lisontekile ngesikhathi sokunciphisa ingcindezi. Kwa-QIANGSENYUAN, leyo modi yokwehluleka yaqedwa ngokukhiya ukulandeleka kwezinto ezingavuthiwe emibikweni yokuhlolwa kokugaya *kanye* nokuqinisekisa amapharamitha omjikelezo oshisayo kuqoqo ngalinye—hhayi nje eyokuqala.
Unqenqema lwabo lobuchwepheshe luqala lapho izitolo eziningi zima khona: ubuhlakani obujulile be-alloy. I-T800 esekelwe ku-Cobalt kanye ne-AMS 5387 akuzona nje "insimbi engenasici." Bafuna amamaki e-carbide akhethekile, amanani okuphakelayo ancishisiwe, ukulungiswa okuqinile, nokuqapha ngesikhathi sangempela okushisayo ukugwema ukuqhekeka okuncane noma ukuhlukaniswa kwezigaba. I-QIANGSENYUAN isebenzisa amaseli omshini azinikele alezi zinto zokusebenza—akukho ukusetha okwabiwe nge-aluminium noma insimbi ethambile. Lokho kuziphatha kubonisa ngobuqotho obuphindaphindayo obuphezulu: I-Ra ≤ 0.4 µm ebusweni obuvaliwe obubalulekile, ngisho nakumabhomu engxubevange ye-cobalt engu-120-mm-diameter abhekane nokushaqeka okushisayo okujikelezayo. Amakhasimende abika ukungasebenzi kabusha kwama-valve okucindezela ezindaweni ezingu-17 zokukhiqiza ezilandelanayo—into esiyiqinisekisile ngocwaningomabhuku lwenkampani yangaphandle.
Ukuhlanganiswa okuqondile akulona igama lokumaketha lapha—indlela abalawula ngayo lokho abanye abangakwazi ukukwenza: ukuxhumana phakathi kokusakaza nokwenza imishini. Insimbi noma insimbi engagqwali ifika inobulukhuni obulawulwayo (HB 220–260) kanye nengcindezi encane eyinsalela—efinyelelwa ngesango elilungiselelwe, isikhunta sesihlabathi esipholile kancane, kanye nokukhululeka kwengcindezi yokudlidliza kwangemva kokusakazwa. Lokho kusho ukukhishwa okuncane kwesitoko ngesikhathi se-CNC, ukubekezelelana okuqinile ezindlini zamasilinda ezinodonga oluncane (±0.015 mm kumabhore angu-Ø180 mm), futhi akukho ukuhlanekezela okumangazayo ngemva kokwelashwa kokushisa kokugcina. Lapho i-OEM yephampu yaseYurophu idinga izindlu zesilinda sephampu yepiston engu-220 mm enobubanzi obungu-0.02 mm ngaphezu kobude obungu-450 mm—kanye nokulandeleka okugcwele kwempahla emuva ku-ingot—ayizange icele izingcaphuno kubathengisi abahlanu. Bathumele imidwebo ngokuqondile ethimbeni lonjiniyela le-QIANGSENYUAN futhi bathola impendulo yokwenziwa komsebenzi emahoreni angu-36, okuhlanganisa nezibuyekezo eziphakanyisiwe ze-GD&T ezehlisa izindleko zokulungisa ngo-40%.
Ikhwalithi ayihlolisiswa ekugcineni—iyakhiwa, igxathu negxathu. Amabha angenayo e-cobalt alloy aqinisekiswa amakhemikhali (OES), usayizi wokusanhlamvu (ASTM E112), kanye nokuhlanzeka kwe-ultrasonic ngaphambi kokulayishwa. Yonke ingxenye eyenziwe ngomshini ingena ekucubungulweni kwe-CMM ihlolwa ezigabeni ezintathu: ngemva kokuqina, ngemva kokuphothula kancane, nangaphambi kokudlula kokugcina. Ukuhlola kokugcina kuhlanganisa ukuhlola okusebenzayo-njengama-valve okuhlola ingcindezi ku-1.5× ukucindezela kokusebenza-nokuhlola okubukwayo ngaphansi kwe-10× ukukhuliswa kokukhubazeka okuncane. Amarekhodi? Idijithali ngokugcwele, iyasesheka, futhi igcinwe iminyaka eyi-10. Elinye ikhasimende laseNyakatho Melika lisitshele: “Siyekile ukwenza okwethu ukuhlola i-athikili yokuqala ngoba imibiko yabo ye-FAIR ihlanganisa idatha ye-metrology eminingi—nokuhlaziya okucacile kwezimbangela—kunelebhu yethu yangaphakathi.”
Ukuthembeka ekwenziweni kwe-OEM akukhona ngentengo ephansi kakhulu noma isikhathi sokuhola esisheshayo. Kumayelana nokwazi kahle ukuthi i-valve yakho yokucindezela izoziphatha kanjani ngemva kwemijikelezo engu-10,000 ku-120°C—nokwethemba umphakeli osesihlolile kakade leso simo ezinhlelweni ezintathu zangaphambili. UBUCHWEPHESHE be-QINGDAO QIANGSENYUAN iletha lokho kuqiniseka ngolwazi lwenqubo eqondene nengxubevange, ukulawula okuhlanganisiwe kokusakazwa kwemishini, kanye nokuqina kwekhwalithi ephatha yonke ingxenye njengengxenye yesistimu ebaluleke kakhulu. Konjiniyela abacacisa izingxenye lapho ukwehluleka kungeyona inketho, ukukhetha akukhona phakathi kwabathengisi—kuphakathi kokunciphisa ubungozi nokwamukela ubungozi. Ilungelo OEM CNC imishini ifektri yenza isinqumo sibe lula.
