Uma othile ethi 'izingxenye zemishini ye-nickel alloy', isithombe sokuqala esivame ukuvela siyinto nje eqinile embhedeni we-CNC. Kodwa yilapho kuqala khona ukwenza lula ngokweqile. Akukhona nje ngobulukhuni; imayelana nobuntu bezinto ezibonakalayo ngaphansi kwengcindezi, umdanso wayo oshisayo, nendlela engadla ngayo ithuluzi buthule uma unganakile. Njengoba sisebenzise izingxenye ukusuka ku-Inconel 718 ukuya ku-Hastelloy C-276, inselele yangempela akukhona nje ukusika—ukuphatha yonke ingxoxo phakathi komshini, umzila wamathuluzi, kanye nentando eqinile ye-alloy.
Umbono Oyiphutha Ngokuphakelayo Okunensayo Nje
Uzokuzwa kakhulu: Ngama-nickel alloys, vele wehlise isivinini sakho nokuphakelayo. Leso isiqalo, kodwa esiyingozi uma kuyisu lakho kuphela. Ngike ngabona izitolo zikufaka enhliziyweni lokhu, zenza yonke into ihamba kancane kabuhlungu, kuphela zigcine zinezindawo eziqiniswe wumsebenzi namathuluzi ahluleka ngenxa yokwanda kokushisa okudlulele endaweni esikiwe, hhayi ngenxa yokuhuzuka. Ingxubevange ayigcini nje ngokuba nzima; iyathukuthela. Ifuna ukugaya inyongo, ukushisela ephuzwini lethuluzi. Ngakho-ke, ukugijima kancane kakhulu ngezinye izikhathi kungaba kubi kunokuba ube nolaka kakhulu. Ukhiye wukukhipha okungaguquki, okulawulwayo kwe-chip. Uma ubona lawo mashiphu ephuma kokunsomi okufiphele esikhundleni segolide elisiliva, usuvele usendaweni eyenza umsebenzi ube lukhuni. Kuwuphawu olubonakalayo olulondoloze imisebenzi eminingi kunanoma yiliphi ithebula lepharamitha elisethiwe.
Ingcindezi epholile kanye nokulethwa akuxoxiswana ngakho lapha. Ukupholisa izikhukhula akwanele. Uyidinga khona lapho onqenqemeni, ungene kusixhumi esibonakalayo sethuluzi le-chip. Sathuthela kumasistimu wokupholisa we-high-press through-tool eminyakeni edlule ngenxa yokugaya iphakethe lethu elijulile emizimbeni yama-valve, futhi kwakungeyona into ewubukhazikhazi—bekuwukuphela kwendlela yokugcina ubuqotho bethuluzi futhi sithole isiphetho esingadingi iviki lokugaya. I-thermal conductivity ephansi yezinto ezibonakalayo iyimpande yobubi; ukushisa kuhlala ngqo esihlokweni. Uma ungakwazi ukuyikhipha, ulahlekelwa.
Ukukhethwa kwamathuluzi kuyeka ukuba mayelana nomkhiqizo futhi kuba mayelana nejometri ne-substrate. Isigayo sokuphela kwe-carbide esijwayelekile siyinto esebenzisekayo lapha. Udinga imitshingo ecijile, epholishiwe ukuze unciphise ukunamathela, kanye nomgogodla oqinile ukuze ubambe izingcindezi. Senza ngendlela efanayo kumajiyometri athile anentamo eqinisiwe ngomsebenzi wethu wokuphrofayili ofinyelela isikhathi eside. Futhi noma kunjalo, impilo yamathuluzi ikalwa ngemizuzu, hhayi amahora. Uhlela ngakho. Uyibhajethi. Noma ubani othembisa ngenye indlela akakenzi izinto eziningi ngomshini.
Lapho Ukusakaza Kuhlangana Nomshini: I-Dimensional Handoff
Lena i-nuance elahlekayo uma isitolo sakho senza imishini kuphela noma senza ukusakaza kuphela. Uma uqala ngokusakazwa komumo we-net-net, njengesikhunta segobolondo noma ukufakwa kwe-investimenti esikhiqiza kukho I-Qingdao Qiangsenyuan Technology Co., Ltd.(QSY), isu lomshini kufanele livume umlando wokulingisa. Awukwazi ukuphatha ingxube ye-nickel engenalutho ngokufana ne-billet eyenziwe. Isikhumba singase sibe nokuhluka okuncane kokuqina, kungase kube nezinto ezisele zegobolondo le-ceramic (nakuba inqubo enhle yokusungula inciphisa lokhu), futhi isimo sokucindezeleka sangaphakathi sihlukile.
Sifunde lokhu ngeqoqo elibuhlungu lezindlu zamaphampu esikhathini esidlule. Ukulingisa (Inconel 625) kukalwe kahle ku-CMM ngemva kokusakaza. Kodwa lapho sithatha iphasi lokuqala elinzima, yonke into yanyakaza. Hhayi okuningi, kodwa kwanele ukusula ubuso obubucayi bengxenye. Udaba kwakungewona umshini; bekungukucindezelwa okusalayo ekubunjweni okukhulula i-asymmetrically. Ukulungisa kwakuyinqubo enezinyathelo eziningi: i-anneal yokunciphisa ingcindezi ngemva kokusakaza (ngisho noma i-spec ingazange ikubize ngokusobala), bese kuba ukusikwa kwesikhumba okulula kakhulu ukuze kusungulwe uhlaka lwedatha olusha, oluzinzile ngaphambi kokuthi kuqale ukuhlukumeza kwangempela. Yengeza isinyathelo, kodwa yaqeda izinsalela. Lolu hlobo lokuhlanganiswa kwenqubo yilokho isitolo esinakho kokubili i-Foundry kanye nesitolo somshini ngaphansi kophahla olulodwa, njenge QSY, kufanele aqonde. Ungabona indlela yethu yokwenza lokhu kugeleza komsebenzi okuhlanganisiwe esizeni sethu kokuthi tsngtaocnc.com.
Iphuzu liwukuthi, ipulani yomshini ayikwazi ukuba khona endaweni engenalutho. Umakhi wemishini udinga ukwazi, noma acabangele, impilo yangaphambilini yengxenye. Ingabe bekufakwe isihlabathi? Ukutshala imali? Ngayinye ishiya indawo ehlukile yokuqala kanye nephrofayili yokucindezeleka. Umsebenzi omuhle wokuqala uvame ukumane uhlanze futhi uthole okuyiqiniso esimweni se-as-cast, noma ngabe kusho ukudela isibonelelo esithe xaxa sesitoko.
Ukugaya (ngokwezwi nezwi) kokusebenza kwangemva kokucubungula
Awuvamisile ukuthola isiphetho sokugcina usuka emshinini ngalawa ma-alloys. Ukugaya, i-EDM, noma umshini wokugeleza onukayo kuvame ukungena. Futhi nalu olunye ugibe: ucabanga ukuthi ungalugaya njengensimbi yamathuluzi. Ama-Nickel alloy adume kabi ngokulayisha amasondo okugaya, ukudala izindawo ezithinteke ukushisa, ngisho nokufaka imifantu emincane uma unolaka kakhulu. Ngikhumbula ngizama ukushaya i-32 Ra endaweni evaliwe yengxenye ye-Hastelloy X. Isigayo sayishiya cishe ku-125. Ukugxumela phakathi nesondo elimahhadla ukuze ufike lapho ngokushesha kwavele kwashisa phezulu. Kwadingeka sihlehle, sisebenzise isondo elithambile, elivuleke kakhulu eliklanyelwe ama-nickel alloys, futhi sithathe amaphasi amancane, esiguli anokupholisa okuningi. Izwakale ingasebenzi kahle, kodwa bekuwukuphela kwendlela yokuthola isiphetho esihlanzekile, esingena-crack esizodlula ekuhlolweni kokungena.
I-Deburring iyisihogo sayo esikhethekile. Ukuqina kwento kusho ukuthi ayinqamuki kahle; kuyagcoba. Ukukhipha ngesandla ngamafayela noma amatshe empeleni kungawenza lukhuni i-burr ngokwayo, iyenze ibe nzima kunomsebenzi womzali. Sibe nempumelelo ngezindlela zamandla ashisayo zamashaneli angaphakathi amancane, ayinkimbinkimbi, kodwa kuyizindleko ezengeziwe okufanele zicatshangelwe kusenesikhathi. Uma uklama ingxenye enekhona langaphakathi elicijile ku-nickel alloy, uqinisile, uklama inkinga yomshini.
Lapho Okukhethekile Kusho Okungaphezu Kwekhemistry Nje
Ukusebenza nge izingxenye zemishini ye-nickel alloy ezimbonini ezifana ne-aerospace noma ukucubungula amakhemikhali kusho ukuthi amaphepha abaluleke njengengxenye ebonakalayo. Ukulandeleka kuphelele. Udinga izitifiketi zezinto ezingavuthiwe (ingot ekhonjiwe noma ibha), udinga ukubhala wonke umjikelezo wokuphatha ukushisa, futhi amashidi akho enqubo yokwenza imishini adinga ukucaciswa ngokwanele ukuze othile, ngokombono, aphindaphinde ingxenye ngqo. Lokhu akuwona umsebenzi we-bureaucratic; yindlela oqinisekisa ngayo ukuthi ingxenye enjinini yejethi noma i-reactor yegesi emuncu ngeke ihluleke. Ukuhlanganisa phakathi kuka-718 no-725, noma ukuguqulwa kwethuluzi elingabhaliwe okuholele ku-notch encane, kungaba nemiphumela engaphezulu kakhulu kwesitezi sesitolo.
Lesi simo sokulawula silolonga ibhizinisi lonke. Kungakho izinkampani ezihlala kulesi sikhala, njengokuthi QSY neminyaka engamashumi amathathu ekulingeni nasekufakeni imishini, yakha amasistimu, hhayi izingxenye zomshini kuphela. Ubungcweti abukho kuphela kukhodi ye-G yomhleli noma ukuthululwa komsunguli; isohlelweni lokuphatha ikhwalithi oluhlanganisa konke. Ufunda ukucabanga mayelana nayo yonke ingxenye yokuphila kusukela ekuncibilikeni kuya ekuhlolweni kokugcina, ngoba noma yisiphi isixhumanisi esibuthakathaka sinqamula iketango. Kuphoqa isiyalo esithile ongasiboni ngaso sonke isikhathi ezitolo zemisebenzi esebenzisa insimbi ethambile usuku lonke.
Ekugcineni, Iphathelene Nokuhlonipha Indaba
Ngemuva kwayo yonke le minyaka, angiwaboni ama-nickel alloys njengezitha, abalingani abanzima nje. Bafuna inhlonipho. Awukwazi ukubahlukumeza. Kufanele ulalele-umsindo wokusikwa, ukubukeka kwe-chip, kudatha evela kuzinzwa zokugqoka zamathuluzi. Ukugijima okuyimpumelelo kuthulile, kunomsindo onganyakazi, opholile kanye nokugeleza okuqhubekayo kwama-chips. Ukwehluleka kuba phezulu, noma kuhogela ukushisa, noma kuphetha ngokukhala okufiphele.
Ukuthathwa kwangempela kwanoma ubani ongena kulokhu akulona ishadi elimangalisayo lesivinini/okuphakelayo. Kuyisimo sengqondo. Qala ngokulandela imithetho, yebo, kodwa zilungiselele ukuzama ngaphakathi kwewindi. Bhala ukuthi yini esebenzayo nengasebenzi. Qonda ukuthi umshayeli wakho obiza kakhulu kungenzeka abe amathuluzi, hhayi isikhathi somshini. Futhi ubambisane nabahlinzeki abayitholayo—kusuka ku-Foundry ehlinzeka ngokulingisa okuzinzile kuya ku-rep wamathuluzi okulethela amamaki namajiometri asebenza ngempela kule nkundla. Kuyi-niche, futhi akuthetheleli, kepha ukuyilungisa kuyanelisa ngendlela emangalisayo. Akukho ukukhohlisa lapho ingxenye iku-CMM futhi umbiko we-NDT ubuya uhlanzekile. Lobo ngubufakazi, khona lapho.
