Ezinsukwini ezimbalwa ezedlule, ikhadi lombiko wentuthuko yeminyaka eyishumi yemboni yezwe lami kanye nolwazi lwamenyezelwa: Kusukela ngo-2012 kuya ku-2021, inani elengeziwe lemboni yezokukhiqiza lizokhuphuka lisuka ku-16.98 trillion yuan liye ku-31.4 trillion yuan, kanye nengxenye yomhlaba. izonyuka isuka cishe ku-20% iye cishe ku-30%.… Into ngayinye yedatha ebabazekayo kanye nempumelelo ephawulwe ukuthi izwe lami lilethe ukweqa okungokomlando ukusuka “kumandla okukhiqiza” kuya “kumandla okukhiqiza”.
Izingxenye eziyinhloko zemishini ebalulekile ngokuvamile kufanele zibe nezakhiwo zesisindo esilula, amandla aphezulu, ukumelana nezinga lokushisa eliphezulu, ukumelana nokugqwala, ukumelana nokugqoka, njll., futhi izinto zendabuko azikwazi ukuhlangabezana nezidingo.Ngokuthuthuka kwesayensi nobuchwepheshe, izinto ezintsha ezifana nama-titanium alloys, ama-nickel alloys, izitsha zobumba ezisebenza kahle kakhulu, izinhlanganisela ze-ceramic-reinforced metal matrix composite, nezinhlanganisela eziqiniswe ngefiber ziyaqhubeka nokuvela.Nakuba lezi zinto ezisetshenziswayo zingahlangabezana nezidingo zokusebenza zezingxenye eziwumgogodla, ukucubungula okunzima kakhulu sekuyinkinga evamile, futhi kuyinkinga izikhungo zocwaningo lwesayensi emhlabeni wonke ebezizama ngayo yonke indlela ukuyixazulula.
Njengobuchwepheshe obusha bokuxazulula le nkinga, ukwenza imishini ye-ultra-high-speed kunethemba elikhulu embonini yokukhiqiza.Ubuchwepheshe obubizwa nge-ultra-high-speed machining bubhekisela kubuchwepheshe bemishini obusha obushintsha amandla okusebenza ngokwandisa isivinini somshini, futhi buthuthukise izinga lokususwa kwezinto, ukunemba komshini kanye nekhwalithi yomshini.Isivinini somshini we-ultra-high-speed sishesha izikhathi ezingaphezu kwezingu-10 kunomshini ovamile, futhi impahla iyasuswa ngaphambi kokuba ikhubazeke phakathi nenqubo yokwenza imishini enesivinini esikhulu.Ithimba labacwaningi le-Southern University of Science and Technology lithole ukuthi lapho isivinini sokucubungula sifinyelela amakhilomitha angu-700 ngehora, isici "sobunzima bokucubungula" sezinto ezibonakalayo siyanyamalala, futhi ukucutshungulwa kwezinto ezibonakalayo "kuphenduka kube nzima kube lula".
I-Titanium alloy iyinto evamile "enzima-emshinini", eyaziwa ngokuthi "i-chewing gum" endabeni.Ngesikhathi sokucutshungulwa, "izonamathela emmese" njengezinti zokuhlafuna ushingamu emazinyweni, yenze "isimila esiqhekezayo".Kodwa-ke, lapho isivinini sokucubungula sikhuphuka sibe yinani elibucayi, i-titanium alloy ngeke "inamathele emmese", futhi ngeke kube nezinkinga ezivamile ekucubunguleni kwendabuko njengokuthi "ukushisa kwe-workpiece".Ngaphezu kwalokho, umonakalo wokucubungula uzophinde ucindezelwe ngokunyuka kwejubane lokucubungula, okwenza umphumela "wesikhumba esilimele".Ubuchwepheshe bemishini ye-Ultra-high-speed abukwazi nje ukuthuthukisa ukusebenza kahle kwemishini, kodwa futhi buthuthukise ikhwalithi yokumaka nokunemba.Ngokusekelwe emibonweni yemishini ye-ultra-high-speed efana ne-"embrittlement material" kanye "nokulimala esikhumbeni", inqobo nje uma kufinyelelwa isivinini esibucayi somshini, izici ezinzima zomshini zizonyamalala, kanye nokucutshungulwa kwezinto ezibonakalayo. kuzoba lula njengokuthi "ukupheka iqatha lenyama ukuxazulula inkomo".
Njengamanje, amandla amakhulu okusetshenziswa kobuchwepheshe bomshini we-ultra-high-speed ahehe ukunaka okusabalele.I-International Academy of Production Engineering ibheka ubuchwepheshe bemishini ye-ultra-high-speed njengendlela yokucwaninga eyinhloko yekhulu lama-21, futhi i-Japan Advanced Technology Research Association nayo ibeka ubuchwepheshe bomshini we-ultra-high-speed njengomunye wobuchwepheshe bokukhiqiza obuhlanu besimanje.
Njengamanje, izinto ezintsha zivela njalo, futhi ubuchwepheshe bomshini we-Ultra-high-speed kulindeleke ukuthi buxazulule ngokuphelele izinkinga zokucubungula futhi ilethe uguquko ekucutshungulweni okuseqophelweni eliphezulu nokusebenza kahle "kwezinto zokwakha ezinzima kuya komshini", kuyilapho i-ultra-high. -amathuluzi omshini wesivinini aziwa ngokuthi "imishini yomama yezimboni" kulindeleke ukuthi abe impumelelo "Into enzima yokucubungula" iyithuluzi elinamandla lokucubungula ubunzima.Ngokuzayo, i-ecology yezimboni eziningi nayo izoshintsha ngenxa yalokho, futhi kuzovela izinkambu ezintsha ezimbalwa zokukhula ngokushesha, ngaleyo ndlela kuguqule imodeli yebhizinisi ekhona futhi kuthuthukiswe ukuthuthukiswa kwemboni yokukhiqiza.
