Uma othile ethi izinsiza zomshini ze-CNC ezinembayo, isiphi isithombe esisidwebayo? Kubantu abaningi abathenga ku-inthanethi, imboni ecwebezelayo, ezenzakalelayo ekhafula izingxenye ezinhle. Iqiniso, le engiyiphile iminyaka, imbi kakhulu. Kumayelana negebe phakathi kwalokho okuthenjiswa yimodeli ye-CAD kanye nalokho okwenziwa yi-chunk ye-17-4PH engagqwali ngaphansi komsiki. Kumayelana nezinqumo ezithule ezenziwe ngo-2 AM zokubamba lokho kubekezelelana okungu-±0.0005 hhayi nje engxenyeni eyodwa, kodwa ngokulandelana kwamakhulu amahlanu. Kulapho isevisi yangempela iqala khona—ngemva kokuba isisho samukelwe.
Isisekelo: Iqala ngokulingisa
Awukwazi ukukhuluma ngakho ukunemba CNC machining esimeni sethu ngaphandle kokuqala umfula. Uhlelo lomshini oluphelele alunamsebenzi uma ukulingisa okuluhlaza kune-porosity efihliwe noma ukushuba kodonga okungahambisani. Sengikubone izikhathi eziningi kakhulu. Kungakho indlela yethu e-QSY ihlanganisiwe. Besilokhu senza isikhunta segobolondo kanye nokutshala imali amashumi amathathu eminyaka, ngakho-ke ngesikhathi ukusakaza okufana nendlu yephampu eyinkimbinkimbi noma umzimba we-valve ufika ku-CNC floor, sesiyazi kakade umlando wayo. Siyazi ukuthi i-316L iqiniswe kanjani, lapho ingcindezi ingaba khona. Lokhu akuwona nje umbono; kusho ukuthi singalungisa kusengaphambili ukulungisa noma izindlela zamathuluzi ukuze sibhekane nalokho kuhluka okuncane kumodeli yegama. Ukwenza umshini wokulingisa ozenzele wona kuwumdlalo webhola ohlukile—awulwi nokungaziwa komunye umuntu.
Lona ugibe ovamile kubathengi. Bathola ukusakaza okushibhile kumthengisi oyedwa futhi bakuthumele Izinsizakalo zemishini ye-CNC kwenye indawo, silindele umlingo. Umakhi wemishini uthola ingxenye enezindawo eziqinile ekupholiseni okungalingani noma ekufakweni kwesihlabathi khona kanye endaweni yokuvala okubalulekile. Izitebele zomsebenzi, iminwe iyakhonjwa, ibiza ibhaluni. Ingxenye yesevisi iyalahleka ekuhumusheni. Indlu ehlanganisiwe efana ne-QSY idonsa leyo ngozi ngaphakathi. Ithimba labasunguli kanye nenduna yemishini bakhuluma ulimi olufanayo ngoba basebhilidini elilodwa, babheke isihambi somsebenzi esisodwa.
Thatha ama-alloys akhethekile, afana ne-nickel-based (cabanga i-Inconel 718). Ukuwakhanda kuyiphupho elibi uma uwaphatha njengensimbi ethambile. Kodwa uma uke wawaphonsa, uqonda ngokuseduze ukwakheka kwawo okusanhlamvu, ukuziphatha kwawo okuqinisa umsebenzi. Uyazi ukuthi ukushisa okuvela ekusakazeni kuthinta ukusebenza kwezindawo ezithile. Ngakho-ke isu lakho le-CNC lengxenye ye-Inconel turbine elilingisi lizohluka kakhulu—i-SFM ehamba kancane, amamaki e-carbide athile, mhlawumbe nokulandelana okuhlukile kokusebenza—uma kuqhathaniswa nokuwenza usuka kubha eyenziwe. Lolo lwazi lubhakwa ohlelweni kusukela ngosuku lokuqala.
Ukubekezelelana Akuzona Nje Izinombolo Ezishicilelwe
Nali iqiniso elisebenzayo: noma ubani angakwazi ukufaka ingxenye eyodwa ekubekezeleni okuphambene endaweni elawulwa yisimo sezulu ngomshini omusha sha. Isevisi ichazwa ngokuyenza ngokungaguquki, ngeshejuli, ngenqwaba yokukhiqiza. Ngikhumbula umsebenzi we-hydraulic manifold block, i-iron ductile iron, edinga ama-callout angempela phakathi kuka-0.05mm kunethiwekhi yezimbobo ezibhoboziwe. Inselele bekungeyona ingxenye yokuqala. Bekuwukugcina lokho ngokuguga kwamathuluzi, ukukhukhuleka okushisayo emshinini phakathi nokugijima kwamahora angu-8, kanye nokuhluka kwamaminithi ekulingisini.
Bekufanele sakhe uhlobo oluzinikele olubhekisela ezicini zedatha ye-as-cast, hhayi ezifanelekile. Sabe sesiqalisa ukuhlola okungaphakathi kwenqubo emshinini wethu we-Okuma CNC ukuze sihlole izindawo ezibucayi zokubhoboza zonke izingxenye eziyi-10, sinxephezela ngokuzenzakalelayo. Leyo yisevisi – isikhathi sobunjiniyela esicwile ekwakhiweni kwenqubo ikhasimende elingakaze lisibone entweni yomugqa we-invoyisi ukunemba imishini. Bavele bathole iphalethi lezingxenye ezilingana zonke, ngaso sonke isikhathi. Uma unganikezi lelo zinga lobunjiniyela bezinqubo, umane uyisitolo semishini, hhayi umhlinzeki wesevisi onembayo.
Futhi ngezinye izikhathi, kufanele uhlehlise. Unjiniyela osemusha wake wachaza ukubekezelelana okungu-±0.001 kubo bonke ubungako bangaphandle obungabalulekile bendlu enkulu yensimbi. Kwakuyingxenye yezimonyo, empeleni. Ukusebenzisa lelo zinga le ukunemba kwe-CNC yonke indawo bekuzophinda kathathu izindleko nesikhathi. Isevisi yethu yayihlanganisa ucingo lokuchaza: Bheka, masibambe lokho ebusweni obukhuphukayo kanye nesithukuthezi, kodwa ake sikukhulule okusele ekubekezeleni okujwayelekile kwezentengiso. Izokongela u-40% futhi ikuthole ngokushesha amaviki amabili. Lokho kuxoxisana kuyingxenye yephakheji. Kwakha ukwethembana futhi kubonisa ukuthi ucabanga ngephrojekthi yabo ephelele, hhayi nje isikhathi sakho sokuphotha.
Okubalulekile Kulawula Umdanso
Ukusebenza ngezinto ezisetshenziswa i-QSY ezisebenza ngokukhethekile kuzo—kusuka kuma-ayina okusansimbi avamile kuya kuma-alloys e-cobalt angavamile—kusho ukuthi incwadi yakho yokudlala yomshini idinga amavolumu amaningi. Imishini yensimbi empunga njengebhotela, kodwa uthuli lwe-graphite lufika yonke indawo, ludala umonakalo kumakhava endlela nezikulufu zamabhola uma isitolo sakho singalungiselwe kona. Sinezindawo ezizinikele kanye nezinhlelo zokukhipha lokho. Insimbi engagqwali, njengo-304 noma 316, imayelana nokulwa nokuqina komsebenzi. Udinga amathuluzi abukhali, i-rake enhle, futhi awukwazi neze ukuvumela ithuluzi ukuthi lihlale. Kuyisigqi osithuthukisayo.
Bese ugxumela kokuthile okufana ne-Monel noma i-Hastelloy. Isilo ezahlukene ngokuphelele. Ama-chips awaphuli; ziphuma zinezintambo futhi ziqinile, njengoshingamu. Angakwazi ukushisela okufakwayo futhi abangele ukwehluleka okuyinhlekelele. Lapha, isevisi isemininingwane emincane: okokupholisa okunengcindezi ephezulu okuhloswe ngqo onqenqemeni lokunqamula nokukhipha ama-chips, izigayo eziguquguqukayo zokuphela kwe-helix ukuphazamisa ukudlidliza kwe-harmonic, kanye neresiphi ethile yokuphakelayo/yesivinini evamise ukuzwakala inolaka. Ufunda lokhu ngokonakalisa izikhala ezimbalwa ezibizayo, ngokungananazi. Leyo ingxenye yeminyaka engaphezu kwengama-30 oyibona esizeni se-QSY—iwumtapo wezincwadi walezo zifundo ezifunde kanzima zomndeni ngamunye wezinto ezibonakalayo.
Ngikhumbula i-prototype yevalvu yokucubungula amakhemikhali ku-alloy esekwe ku-cobalt. Ukuphrinta kubize ukuqedwa kwesibuko esihlalweni esicijile. Yonke indlela yokupholisha ejwayelekile yehlulekile; impahla yayingazweli kakhulu. Sigcine sekufanele sakhe iphasi yomshini wokugeleza we-micro-abrasive ngokwezifiso ngemva komsebenzi we-CNC. Belungekho kusikophu sokuqala, kodwa bekudingeka ukuhlangabezana ne-speclic yokusebenza. Lelo yicala elingathandeki Izinsizakalo zemishini ye-CNC-ukuxazulula izinkinga neklayenti, hhayi lona kuphela.
Lapho Ukunemba Kuhlangana Nokulethwa
Yilapho izitolo eziningi ziwa khona. Bangakwazi ukushaya uphawu lwekhwalithi, kodwa abakwazi ukukwenza ngevolumu noma ngesikhathi. Ukunemba akusona nje isilinganiso sobukhulu; kuyisithembiso sokubikezela. Ukutshala kwethu imali ezikhungweni zemishini evundlile enamapallet amaningi bekungelona nje okwejubane. Okokuqhubeka. Ngenkathi i-pallet eyodwa isebenzisa umjikelezo wamahora angu-4 eqoqweni lokufakwa kwe-stainless, opharetha uhlela ukulungiswa okulandelayo komsebenzi wensimbi ekhonjiwe kwenye i-pallet. I-spindle ayiyeki. Kuklayenti, lokhu kusho ukuthi usuku lwalo lokulethwa luqinile.
Kodwa ngisho nesistimu engcono kakhulu ishaya ama-snags. Ithuluzi liyaphuka kungalindelekile. Ukulingisa kunesici esingazange sibonakale kwaze kwaba yilapho kusikwa kokuqala. Isevisi ichazwa impendulo. Ingabe uyayifihla futhi unethemba lokuthi uzoyithola? Noma ingabe uyaxhumana ngokushesha? Sesizakhele umkhuba wokuxhumana ngokweqile. I-imeyili esheshayo enesithombe: Kutholwe imbobo yesihlabathi engxenyeni 3 esiteshini B. Iyakwazi ukuhlengwa ngokulungiswa kwe-weld, izongeza amahora angu-8. Iyaqhubeka ngaphandle uma kuyalwe ngenye indlela ngo-5 PM. Igcina ubambiswano lungokoqobo. Amaklayenti ayakwazisa obala, ngisho noma kuyizindaba ezimbi. Bayazi ukuthi abaphakelwa ulayini.
Lesi sigqi sokusebenza sibalulekile ezimbonini esizihlinzekayo—uwoyela negesi, amaphampu, imishini esindayo. Ingxenye ebambezelekile eyenziwe ngomshini wokunemba ingabamba umugqa wokuhlanganisa wezigidigidi zamadola. Isisindo salokho sizwakala phansi esitolo. Iguqula umsebenzi usuke ekubeni wenze izingxenye nje ube isixhumanisi esibalulekile echungechungeni lokuhlinzeka lomunye umuntu. Leso sibopho silolonga zonke izinqumo, imuphi umsebenzi olayishwa eduze nokuthi mangakanani amathuluzi ayisipele esiwagcina eshalofini lezinto ezigijima kakhulu.
Ukuxhawula Kwedijithali
Ekugcineni, isiphetho sangaphambili. Iklayenti engase ibe khona ihlala endaweni efana nayo tsngtaocnc.com. Badinga ukucaphuna a ukunemba CNC machining umsebenzi. Ukunethezeka nokucaca kwaleyo nqubo ukuhlolwa kokuqala kwesevisi yakho. Sithola ama-RFQ anakho konke ukusuka kumafayela e-3D STEP aphelele ukuya esithombeni esilufifi somdwebo odwetshwe ngesandla ku-napkin. Isevisi isendleleni okuphatha ngayo kokubili. Ngomdwebo we-napkin, ucingo olusheshayo lokubuza imibuzo efanele: umsebenzi, impahla, i-interfaces ebalulekile. Ngefayela elihle kakhulu elithi STEP, umbiko onemininingwane we-DFM (Design for Manufacturability) ngaphakathi kwekhwothi, ogqamisa abashayeli bezindleko abangaba khona njengezimbobo ezijulile, ezinobubanzi obuncane noma izindonga ezizacile kakhulu ezingase zidlidlize ngesikhathi sokusika.
Lokhu kucaphuna okuxoxisanayo yikho okuhlukanisa i-QSY nengosi yemishini ye-inthanethi engenabuso. Kusekelwe ekuboneni izinkulungwane zemisebenzi yeqa umkhawulo. Uthuthukisa umuzwa wemvelo. Ungabheka imodeli futhi wazi ngokushesha izici ezimbili noma ezintathu ezizoba inselele. Ukukhomba lokho ngaphambili, mhlawumbe ukuphakamisa i-tweak yedizayini encane enciphisa isikhathi somshini, kwakha ukwethembeka okukhulu. Ikhombisa i Izinsizakalo zemishini ye-CNC zisekelwa isipiliyoni sangempela sesitezi sesitolo, hhayi nje iqembu labadayisi.
Ekugcineni, ukunemba kwe-CNC machining njengesevisi kuyinto eqhubekayo. Kuqala ngokuqonda i-genesis yezinto ezingavuthiwe, kugeleza ku-gritty reality of chips kanye nokubekezelela phansi esitolo, futhi kuqiniswa ukulethwa okuthembekile nokuxhumana okuthembekile. Akuyona impahla. Kuwumsebenzi wezandla osekelwa amasistimu, futhi ukuphela kwendlela yokuguqula ipulani yekhasimende ibe ingxenye esebenzayo, iqoqo ngemva kwenqwaba, unyaka nonyaka. Yilokho okukhiphayo kwangempela, okubaluleke kakhulu kunensimbi ngokwayo.
