Umshini we-alloy wangokwezifiso uhlala empambanweni yesayensi yezinto ezibonakalayo kanye nokunemba kokukhiqiza. Kubathengi be-OEM nonjiniyela abathola izingxenye zezindawo ezibolayo, ezishisa kakhulu, noma ezibucayi, ukukhetha kwengxubevange nendlela esebenza ngayo kunganquma ukuthi ingxenye iyasinda yini empilweni yayo yesevisi noma yehluleke ngaphambi kwesikhathi. Ngokungafani nokwenza i-aluminium noma insimbi ethambile, ukusebenza ngama-alloys akhethekile kwethula amawindi enqubo aqinile, ukuguga kwamathuluzi asheshayo, nezikhonkwane eziphakeme kuzo zonke izigaba—kusuka ekudwebeni kokubuyekezwa kuya ekuhlolweni kokugcina.
Lesi sihloko sihlola amaqiniso angokoqobo omshini wengxubevange yangokwezifiso: yiziphi ingxubevange evame ukucaciswa, ukuthi ziziphatha kanjani ngaphansi kwethuluzi lokusika, yiziphi izici zedizayini ezidinga ukunakwa okwengeziwe, nokuthi abathengi bangahlola kanjani ukuthi umphakeli uwuhlomele ngempela umsebenzi. Umgomo awukona ukwenza wonke umfundi abe uchwepheshe bemishini, kodwa ukunikeza umongo wezobuchwepheshe odingekayo ukuze ubuze imibuzo engcono, ukulungiselela ama-RFQ acace kakhudlwana, futhi ugweme ukungaqondi kahle okubizayo phakathi kwenhloso yokuklama neqiniso lokukhiqiza.
Iyini i-Custom Alloy Machining?
Ukucutshungulwa kwe-alloy ngokwezifiso kubhekisela ekukhiqizweni kwezingxenye zensimbi kusuka kumamaki e-alloy acacisiwe, aklanyelwe umdwebo wekhasimende, ukucaciswa kwezinto ezibonakalayo, kanye nenqubo yokwamukela. Isici "esingokwezifiso" sisebenza kumaleveli amabili: okokusebenza kuvame ukukhethwa ngenhlanganisela ethile yokumelana nokugqwala, amandla ezinga lokushisa eliphezulu, noma ukusebenza okugugile kunokuba kukhethwe kukhathalogi yesitoko esijwayelekile; kanye nejiyomethri, ukubekezelelana, kanye nezimfuneko zokuhlola kuchazwa uhlelo lokusebenza kunezinga lomkhiqizo ojwayelekile.
Lokhu kuhlukanisa inkambiso yengxubevange machining emsebenzini jikelele CNC umsebenzi ngezindlela eziningana ezingokoqobo. Izinto ngokwazo zingase zifike njenge-billet engumgunyathi, isitokwe esisansimbi, noma ipuleti kunesitoko sebha evamile, edinga amasu ahlukene okulungisa kanye nama-rough. Amapharamitha okusika kufanele athuthukiswe azungeze ukuthambekela kokuqina komsebenzi we-alloy, ukuqhutshwa kwe-thermal, nobulukhuni bokushisa kunokuba kubolekwe ohlelweni lwensimbi evamile noma lwe-aluminium. Futhi ngenxa yokuthi ama-alloy akhethekile avame ukuthwala izindleko zempahla eziphakeme kakhulu kanye nezikhathi zokuhola ezinde, umkhawulo we-scrap uncane—iphutha elilodwa lomshini ekuqanjweni okusekelwe ku-nickel lingamela ukulahlekelwa okukhulu ngaphambi kokuthi kuqale nokuqala kokudlula.
Ukucutshungulwa kwe-alloy ngokwezifiso kuvame ukucaciswa lapho ingxenye kufanele yenze ngaphansi kwezimo ezikhipha izinto ezivamile: okokusebenza kwamakhemikhali okuvezwa kwabezindaba abanolaka, izingxenye zikawoyela negesi ezidinga ukumelana nesevisi emuncu, izinsimbi ezifaka izinga lokushisa eliphezulu kanye ne-valve trim, nezingxenye zokugqoka ezingakwazi ukugcotshwa. Kulezi zimo, ukukhethwa kwe-alloy kanye nenqubo yomshini akuzona izinqumo ezizimele-kumele zithuthukiswe ndawonye.
I-Common Alloy Materials for Custom Machining
Ama-alloys okuvame ukuhlangatshezwana nawo ezicelweni zomshini wangokwezifiso awela emindenini embalwa, ngayinye enezici ezihlukile zomshini ezilolonga indlela ingxenye okufanele idizayinwe futhi icashunwe ngayo.
Izinsimbi ezingagqwali nama-alloys amelana nokugqwala hlanganisa i-spectrum ebanzi kusukela kumabanga e-free-machining asebenziseka kalula kuye kumamaki e-austenitic aphezulu ane-alloy kanye ne-duplex asebenza kanzima kakhulu. I-alloy 28 (UNS N08028), isibonelo, icaciswe endaweni egqwala kakhulu ehlanganisa i-phosphoric acid emanzi kanye nemithombo yegesi emuncu, kodwa okuqukethwe kwayo kwe-nickel ephezulu kanye ne-chromium kukhiqiza ukuqina okuphezulu kanye nokuthambekela ekuqhekekeni kwe-chip kanye nonqenqema olwakhiwe ngesikhathi sokuphenduka. Amabanga afana no-316L kanye no-17-4 PH avame ukutholakala kodwa asadinga ukunakwa ekusebenzeni kanzima ngesikhathi sokumba nokuthepha.
Ama-alloys asekelwe ku-nickel njenge-Inconel 625 kanye ne-718 zicaciswe amandla ezinga lokushisa eliphezulu nokumelana nokugqwala kuwoyela negesi, i-aerospace, kanye nokucubungula kwamakhemikhali. I-Inconel 718 ikakhulukazi yaziwa ngokugcina amandla emazingeni okushisa aphakeme, ahumusha ngokuqondile amandla okusika aphezulu kanye nokugqoka kwamathuluzi okusheshayo ngesikhathi somshini. Lawa ma-alloys nawo athambekele ekubeni lukhuni umsebenzi onzima, okusho ukuthi iphasi eliqeda ukukhanya elihlikihlayo kunokuba lisike lingashiya ungqimba olungaphezulu oluqinile olulimaza ithuluzi elilandelayo.
Ama-alloys asekelwe ku-cobalt, ngokuvamile amelelwa amamaki e-Stellite, akhethelwe ukumelana nokugqokwa kwe-valve trim, bushings, kanye nokufaka lapho i-galling ne-abrasive wear ikhathaza khona. I-Stellite 6, ngokwesibonelo, yaziwa ngokugcina ubulukhuni emazingeni okushisa aphakeme kanye nokumelana nokungqubuzana okomile, kodwa izakhiwo zayo ezingagugi zikwenza kube nzima ngokuhambisanayo umshini osebenzisa amathuluzi avamile.
Izingxube ze-Titanium zinikeza izilinganiso eziphezulu zesisindo nesisindo nokumelana nokugqwala, ikakhulukazi emkhathini nasezinhlelweni zezokwelapha. I-thermal conductivity yabo ephansi ibangela ukushisa okusika ukuthi kugxile onqenqemeni lwamathuluzi kunokuba kuhlakazeke ku-chip, kusheshise ukuguga kwamathuluzi nokwenza ukuphatha okushisayo kube ukukhathazeka okumaphakathi kwemishini.
Ama-alloys ethusi kanye nama-bronze akhethekile zivela ezinhlelweni ezidinga ukushintshwa kukagesi, izakhiwo ezithwalayo, noma ukumelana namanzi olwandle. Nakuba ngokuvamile esebenza kahle kakhulu kune-nickel noma i-cobalt alloys, angaveza izinselelo zawo ngama-gummy chips nokulawula kokuqeda phezulu.
Iphuzu elibalulekile labathengi ukuthi "ingxubevange" ayisona isigaba esisodwa. Umphakeli oshicilela insimbi engagqwali engu-304 ngendlela efanele angase angabi nalo ulwazi ngokuziphatha kokuqina komsebenzi kwe-Inconel 718, futhi isitolo esishintsha i-Monel 400 njalo singase sidinge ukuthuthukisa inqubo entsha ye-Stellite bushing. Ukucaciswa kwezinto kufanele kushiwo ngokucacile emdwebeni, ngokuhlonzwa kwezinga elisebenzayo (i-ASTM, i-UNS, i-EN, noma elilinganayo), futhi abahlinzeki kufanele babuzwe ngokuqondile ukuthi banalo yini ulwazi lwangaphambili ngalelo banga elithile noma umndeni walo oseduze.
