Ithuluzi lokusika
Emshinini we-graphite high-speed machining, ngenxa yobunzima bezinto ze-graphite, ukuphazamiseka kokwakheka kwe-chip kanye nomthelela wezimpawu zokusika ngesivinini esikhulu, ukucindezeleka kokusika kwakhiwa ngesikhathi senqubo yokusika futhi kukhiqizwa ukudlidliza okuthile, futhi Ithuluzi lijwayele ukushesha ubuso nobuso obuseceleni Ukuhushula kuthinta kabi impilo yesevisi yethuluzi, ngakho-ke ithuluzi elisetshenziselwa imishini ye-graphite enesivinini esikhulu lidinga ukumelana nokugqokwa okuphezulu kanye nokumelana nomthelela.
Amathuluzi ahlanganiswe nedayimane anezinzuzo zobulukhuni obuphezulu, ukumelana nokugqokwa okuphezulu, kanye ne-coefficient ephansi yokungqubuzana. Njengamanje, amathuluzi ahlanganiswe nedayimane ayisinqumo esingcono kakhulu sokucubungula i-graphite.
Amathuluzi okwenza i-graphite nawo adinga ukukhetha i-engeli yejiyomethri efanelekile, esiza ukunciphisa ukudlidliza kwamathuluzi, ukuthuthukisa ikhwalithi yomshini, nokunciphisa ukuguga kwamathuluzi. Ucwaningo lwezazi zaseJalimane mayelana nendlela yokusika i-graphite lubonisa ukuthi ukukhishwa kwe-graphite ngesikhathi sokusikwa kwe-graphite kuhlobene eduze ne-rake angle yethuluzi. Ukusika i-engeli ye-rake engalungile kukhulisa ingcindezi ecindezelayo, enenzuzo ukukhuthaza ukuchotshozwa kwezinto, ukuthuthukisa ukusebenza kahle kokucubungula, nokugwema ukukhiqizwa kwezingcezu zegraphite ezinosayizi omkhulu.
Izinhlobo zesakhiwo samathuluzi ezivamile zokusika kwe-graphite high-speed zihlanganisa izigayo zokugcina, abasiki bebhola kanye nabasiki be-fillet. Izigayo zokuphela ngokuvamile zisetshenziselwa ukucutshungulwa kwendawo enezindiza ezilula nezimo. Abasiki be-ball-end milling bangamathuluzi afanelekile okucubungula izindawo ezigobile. Abasiki be-fillet banezici zabo bobabili abasiki bebhola kanye nezigayo zokuphela, futhi zingasetshenziselwa kokubili izindawo ezigobile neziyisicaba. Okokucubungula.
Ukusika imingcele
Ukukhethwa kwemingcele yokusika enengqondo ngesikhathi sokusika isivinini esikhulu se-graphite kubaluleke kakhulu ekuthuthukisweni kwekhwalithi yokucubungula nokusebenza kahle kwe-workpiece. Njengoba inqubo yokusika ye-graphite high-speed machining iyinkimbinkimbi kakhulu, lapho ukhetha imingcele yokusika kanye namasu okucubungula, udinga ukucabangela isakhiwo se-workpiece, izici zamathuluzi omshini, amathuluzi, njll. wokusika izivivinyo.
Ukuze uthole izinto ze-graphite, kuyadingeka ukukhetha imingcele yokusika ngesivinini esikhulu, ukudla okusheshayo, kanye nenani elikhulu lamathuluzi enkambweni yomshini onzima, ongathuthukisa ngokuphumelelayo ukusebenza kahle kwemishini; kodwa ngenxa yokuthi i-graphite ijwayele ukucwiywa phakathi nenqubo yokwenza, ikakhulukazi emaphethelweni, njll. Isikhundla kulula ukwenza isimo esimangelengele, futhi isivinini sokuphakela kufanele sehliswe ngokufanelekile kulezi zindawo, futhi akufanelekile ukudla ukudla okukhulu. isamba sommese.
Ezingxenyeni ze-graphite ezinodonga oluncane, izizathu zokuqhekeka kwemiphetho namakhona zibangelwa ngokuyinhloko ukusika umthelela, ukuvumela ummese nommese wokunwebeka, kanye nokuguquguquka kwamandla okusika. Ukunciphisa amandla okusika kunganciphisa ummese nommese wenhlamvu, kuthuthukise ikhwalithi yokucubungula indawo yezingxenye ze-graphite ezinezindonga ezincane, futhi kunciphise ukuphuka nokuphuka kwamakhona.
Ijubane lokuphotha lesikhungo somshini wesivinini esikhulu se-graphite ngokuvamile sikhulu. Uma amandla okuphotha wethuluzi lomshini evumela, ukukhetha isivinini sokusika esiphezulu kunganciphisa ngempumelelo amandla okusika, futhi ukusebenza kahle kokucubungula kungathuthukiswa kakhulu; endabeni yokukhetha isivinini sokuphotha, Inani lokuphakelayo ngezinyo ngalinye kufanele liguqulelwe kusivinini sokuphotha ukuze kuvinjelwe ukuphakela okushesha kakhulu kanye nenani elikhulu lethuluzi ukuze libangele ukuphuka. Ukusika i-graphite kuvame ukwenziwa ngethuluzi lomshini okhethekile we-graphite, isivinini somshini ngokuvamile si-3000 ~ 5000r/min, futhi isivinini sokuphakela ngokuvamile singu-0. 5 ~ 1m/min, khetha isivinini esiphansi ngokuqhathaniswa somshini onzima kanye nesivinini esikhulu. yokuqeda. Ezikhungweni zemishini ye-graphite yesivinini esikhulu, isivinini sethuluzi lomshini siphezulu kakhulu, ngokuvamile siphakathi kuka-10000 no-20000r/min, futhi izinga lokuphakelayo ngokuvamile liphakathi kuka-1 no-10m/min.
Graphite High Speed Machining Center
Inani elikhulu lothuli likhiqizwa ngesikhathi sokusikwa kwe-graphite, okungcolisa imvelo, kuthinta impilo yabasebenzi, futhi kuthinte amathuluzi omshini. Ngakho-ke, amathuluzi omshini wokucubungula i-graphite kufanele afakwe izinto ezinhle zokuvikela uthuli nezisusa uthuli. Njengoba i-graphite ingumzimba we-conductive, ukuze kuvinjwe uthuli lwe-graphite olukhiqizwa ngesikhathi sokucubungula ukuthi lungene ezingxenyeni zikagesi zethuluzi lomshini futhi lubangele izingozi zokuphepha njengezifunda ezimfushane, izingxenye zikagesi zethuluzi lomshini kufanele zivikelwe njengoba kudingekile.
Isikhungo semishini ye-graphite high-speed machining samukela i-spindle kagesi enesivinini esiphezulu ukuze sifinyelele isivinini esikhulu, futhi ukunciphisa ukudlidliza kwethuluzi lomshini, kuyadingeka ukuklama isikhungo esiphansi sesakhiwo sokudonsela phansi. Indlela yokuphakelayo ngokuvamile isebenzisa isikulufu sebhola esinesivinini esikhulu nokunemba okuphezulu, futhi idizayina izinto ezilwa nothuli [7]. Ijubane lokuphotha le-graphite high-speed machining centre livamise ukuba phakathi kuka-10000 no-60000r/min, isivinini sokuphakela singaba phezulu size sifike ku-60m/min, futhi ukujiya kodonga lokucubungula kungaba ngaphansi kuka-0. 2 mm, ikhwalithi yokucubungula okungaphezulu kanye ukunemba kokucubungula kwezingxenye kuphezulu, okuyindlela eyinhloko yokufeza ukusebenza kahle okuphezulu nokucubungula okuphezulu kwe-graphite okwamanje.
Ngokusetshenziswa okubanzi kwezinto ze-graphite kanye nokuthuthukiswa kobuchwepheshe bokucubungula i-graphite esheshayo, imishini yokucubungula i-graphite esebenza kahle ekhaya nakwamanye amazwe iye yanda kancane kancane. Umfanekiso 1 ubonisa izikhungo zemishini ye-graphite enesivinini esikhulu ezikhiqizwe abanye abakhiqizi basekhaya nabangaphandle.
I-OKK's GR400 isebenzisa isikhungo esiphansi samandla adonsela phansi kanye nesakhiwo sebhuloho ukuze kuncishiswe ukudlidliza komshini kwethuluzi lomshini; yamukela i-C3 yokunemba isikulufu kanye nomhlahlandlela we-roller ukuze kuqinisekiswe ukusheshisa okuphezulu kwethuluzi lomshini, ukunciphisa isikhathi sokucubungula, futhi yamukele ukungezwa konogada be-splash Idizayini yeshidi leshidi elivalwe ngokugcwele lekhava yangaphezulu yomshini ivimbela uthuli lwe-graphite. Izinyathelo zokuvikela uthuli ezamukelwa yi-Haicheng VMC-7G1 akuyona indlela evame ukusetshenziswa yokuhlanza, kodwa ifomu lokuvala ikhethini lamanzi, kanye nedivayisi ekhethekile yokuhlukanisa uthuli. Izingxenye ezihambayo ezifana nama-rails omhlahlandlela kanye nezinduku ze-screw nazo zifakwe ama-sheaths kanye nedivayisi yokukhuhla enamandla ukuze kuqinisekiswe ukusebenza okuzinzile kwesikhathi eside kwethuluzi lomshini.
Kungabonakala kumapharamitha wokucaciswa kwesikhungo semishini yesivinini esikhulu se-graphite kuThebula 1, ukuthi isivinini sokuphotha kanye nesivinini sokuphakela sethuluzi lomshini kukhulu kakhulu, okuyisici se-graphite high-speed machining. Uma kuqhathaniswa namazwe angaphandle, izikhungo zasekhaya ze-graphite machining zinomehluko omncane ekucacisweni kwethuluzi lomshini. Ngenxa yokuhlanganiswa kwamathuluzi omshini, ubuchwepheshe kanye nomklamo, ukunemba komshini wamathuluzi omshini kuphansi kakhulu. Ngokusetshenziswa kabanzi kwe-graphite embonini yezokukhiqiza, izikhungo zomshini we-graphite ezinesivinini esikhulu ziye zadonsa ukunakwa okwengeziwe. Izikhungo ze-graphite machining ezisebenza kahle kakhulu nezisebenza kahle kakhulu zenziwa futhi zenziwa. Ubuchwepheshe bokucubungula obuthuthukisiwe bamukelwa ukunikeza ukudlala okugcwele kuzici zabo nokusebenza ukuze kuthuthukiswe i-graphite. Ukusebenza kahle kokucubungula kanye nekhwalithi yezingxenye kubaluleke kakhulu ekuthuthukiseni ubuchwepheshe bokucubungula ama-graphite wezwe lami.
ngamafuphi
Lesi sihloko sixoxa ngokuyinhloko ngenqubo ye-graphite machining kusukela ezicini zezimpawu ze-graphite, inqubo yokusika kanye nesakhiwo sesikhungo se-graphite high-speed machining. Ngokuthuthukiswa okuqhubekayo kobuchwepheshe bamathuluzi omshini kanye nobuchwepheshe bamathuluzi, ubuchwepheshe be-graphite high-speed machining budinga ucwaningo olujulile ngokusebenzisa izivivinyo zokusika kanye nezicelo ezingokoqobo ukuze kuthuthukiswe izinga lobuchwepheshe le-graphite machining ku-theory nokusebenza.
