Lapho onjiniyela becacisa izingxenye ezinokubekezelelwa okungu-±0.005 mm, imibhobho ye-cobalt alloy eqinile, noma izindlu zamavalvu okucindezela okufanele zikwazi ukulayisha umjikelezo wamabha angu-300+—“imboni enkulu yomshini wokunemba” ayiyona nje incazelo. Kungumkhawulo. Ulayini onqamule kuphela izitolo ezilawula i-metallurgy, i-geometry, ne-microstructure ekuhambeni komsebenzi okufanayo—hhayi ngaphesheya kwe-handoffs.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ngalolo hlobo lwesikhungo eQingdao. Akusona isitolo semisebenzi yezinjongo ezijwayelekile. Akuyona indawo yokulingisa kuphela noma umkhiqizi wenkontileka ye-CNC kuphela. Iphansi layo lokukhiqiza elithobela i-ISO lihlanganisa ukutshala imali, ukwenziwa kwemishini ye-CNC ye-multi-axis, ukwelashwa kokushisa, nokuqedwa kwendawo ngaphansi kwesistimu eyodwa yekhwalithi—nokulandeleka okugcwele kusukela kusitifiketi sempahla eluhlaza kuya embikweni wokugcina we-CMM.
Sibone amakhasimende ethumela imidwebo yezingxenye zephampu ye-cobalt alloy AMS 5387 elindele izikhathi zokuhola zezinyanga ezintathu—futhi athole ama-prototypes asebenzayo ezinsukwini eziyi-18. Kungani? Ngoba iqembu labo liqinisekisa i-GD&T *ngaphambi* kokucaphuna. Bahlaba umkhosi ngokuphazamiseka ezindlini zamasilinda ephampu yepiston ngesikhathi sokubuyekezwa konjiniyela—hhayi ngemva kokuhlolwa kwe-athikili yokuqala. Bathola amabhilidi e-cobalt-nickel ebanga le-T800 anosayizi wokusanhlamvu oqinisekisiwe kanye nokusabalalisa kwe-carbide—hhayi nje “ingxubevange ye-cobalt.” Lelo zinga lokuhlanganisa okuqondile liqeda ukukhukhuleka okuphakathi kokuncipha kokusakaza kanye nokwenza imishini yokugcina. Iguqula izitaki zokubekezelela zetiyori zibe amandla enqubo ephindaphindwayo.
- Izingxenye Zomshini ze-CNC: Amakhonta ayinkimbinkimbi ezisekelweni zephampu yensimbi engagqwali, anokubekezelelwa kwendawo yangempela okugcinwe ku-0.01 mm kuzici zedatum ze-Ø200 mm
- Izingxenye ze-Cobalt-Nickel Alloy: Imibhobho namapulaki afakwe ngomshini kusukela kusitoko se-AMS 5387—ukuqina kwempahla 42–48 HRC, ukuqedwa kwengaphezulu Ra ≤0.8 µm ngaphandle kokupholisha kwesibili
- Insimbi & Steel Castings: Amarola ewintshi yemoto yobunjiniyela be-sand-cast—afakwe ku-±0.015 mm kumadiamitha ejenali, anokufana kokuqina okuqinisekisiwe kuzo zonke izigaba
- Izingxenye Zenqubo Ye-Hybrid: Izindlu zesilinda ezifakwe ngensimbi eyi-ductile, bese zibhokwa ngokunemba futhi zacijwa ukuze zifane nezicaciso ze-hydraulic seal-awekho amalophu okusebenza kabusha
Abanye bangase baphikise ngokuthi ukulingisa nokunemba okuphezulu kungokwezindawo ezihlukene. Kodwa ekusetshenzisweni komhlaba wangempela—ikakhulukazi amavalvu okulawula uwoyela negesi noma imihlangano yephampu yasogwini—umlando wokushisa ubalulekile. Ingxenye enamazinga okupholisa angalawuleki idala ingcindezi eyinsalela. Lokho kucindezeleka kuyahlanekezela ngesikhathi sokusebenza kokugcina. I-QINGDAO QIANGSENYUAN igwema lokhu ngokuphatha amapharamitha wokuqinisa *kanye* nokuhlola ukuzinza kwangemva komshini. Imibiko yabo ye-CMM ihlanganisa idatha yesinxephezelo sokunwetshwa kwe-thermal eboshelwe emaloguni okushisa esitolo esizungezile. Abahloli babo abagcini nje ukulinganisa ubukhulu—babuhlobanisa namarekhodi omjikelezo wokwelashwa okushisa namamephu wokuqina okuncane.
Leso siyalo sibonakala ngezindlela zokwehluleka. Sibuyekeze izingxenye ezinqatshiwe ezivela kwabanye abahlinzeki: imibhobho ye-cobalt alloy ene-subsurface microcracks eduze kwamaphaseji apholile; imizimba yamavalvu ensimbi engagqwali enogqinsi olungahambisani nongqimba lwe-passivation ezindaweni zokukhwelana; isisekelo sephampu esijikijela ngemva kwamahora angu-72 okuhlolwa komthwalo omile. Azikho kulezo zinkinga ezivela emibikweni ye-FA ye-QINGDAO QIANGSENYUAN. Ukuqinisekiswa kwezinto ezifikayo kuhlanganisa nokuhlaziywa kwe-spectrographic—hhayi nje izitifiketi zokugaya. Ukuhlola okungaphakathi kwenqubo kusebenzisa iziqhathanisi zokubona *kanye* nama-tactile probe ku-radio ebalulekile. Ukuhlolwa kokusebenza kokugcina kuphindaphinda ingcindezi yesevisi yangempela, izinga lokugeleza, namaphrofayela okugibela ibhayisikili—hhayi nje imithwalo yobufakazi obumile.
Ukuthembeka kokulethwa kulandela ngokwemvelo. Lapho iphrojekthi yakho idinga izingcezu ezingama-42 ze-T800 alloy center shaft roller engajwayelekile—ilinye lidinga imisebenzi yemishini ehlukene engu-14, ukwelapha okubili kokushisa, kanye nezibhobo zangaphakathi ezipholishelwe ngogesi—awukwazi ukukhokhela ukushelela kweshejuli ngenxa yokungahambi kahle komhlinzeki. Ukuhamba komsebenzi wabo okuthambile kwabela amaseli azinikele emindenini ene-alloy ephezulu. Imisebenzi ye-cobalt-nickel isebenza emishinini enamathuluzi e-ceramic, ama-spindle ashiselwe ngaphambili, nezinto ezidayisiwe zokudlidliza—hhayi izikhungo zokusika kabusha ze-aluminum. Ukuhlelwa kokukhiqiza kubala impilo yokugqoka kwamathuluzi ngeqoqo ngalinye, hhayi nje isikhathi sokujikeleza. Babambelela kanjalo kumafasitela wokulethwa kwezinsuku ezingu-±3 kuma-oda evolumu ephakathi, ngisho nokuqedwa kwendawo okungokwezifiso okufana ne-HVOF tungsten carbide coating noma i-nitride case harding.
Ifekthri enkulu yokwenza imishini enembayo ithola igama layo hhayi ngezithombe eziyisikwele—kodwa ngokubekezelela okuncane kakhulu eyibamba njalo, ingxubevange eqinile ewumshini ngaphandle kwe-scrap, kanye nejiyomethri eyinkimbinkimbi kakhulu eyilethayo ngaphandle kokuyekethisa kwezobunjiniyela. I-QINGDAO QIANGSENYUAN TECHNOLOGY ihlangabezana nalelo zinga nsuku zonke. Ukugxila kwayo kuhlala kubukhali: izakhi zezimboni ezisebenzayo lapho ukwehluleka kungeyona inketho-amavalvu okucindezela, izindlu zokumpompa, amawintshi amawintshi, imibhobho ye-cobalt alloy. Hhayi ama-prototypes. Hhayi okukodwa. Izingxenye ezibalulekile zemishini ezakhelwe ukubekezela, hhayi ukuboniswa.
Konjiniyela abacacisa izingxenye zangokwezifiso ezibekezelela kakhulu ku-hydraulics, amandla, noma okokusebenza kweselula esindayo—yilapho ukunemba kobukhulu kuhlangabezana khona nesiqiniseko se-metallurgical. Lapho "imboni yemishini enembayo enkulu" iyeka ukuba ulimi lokuthengisa bese iqala ukuchaza lokho okungenzeka ngokobuchwepheshe.
