1. MayelanaI-Graphite milling cutter
Uma kuqhathaniswa nama-electrode ethusi, ama-electrode e-graphite anezinzuzo ezifana nokusetshenziswa okuphansi kwama-electrode, isivinini sokucubungula ngokushesha, ukusebenza kahle komshini, ukunemba okuphezulu kokucubungula, ukuwohloka okuncane kokushisa, isisindo esincane, ukwelashwa okulula kwendawo, ukumelana nokushisa okuphezulu, izinga lokushisa eliphezulu lokucubungula, nokunamathela kwe-electrode. .
Nakuba i-graphite iyinto elula kakhulu ukusika, impahla ye-graphite esetshenziswa njenge-electrode ye-EDM kumele ibe namandla anele ukugwema ukulimala ngesikhathi sokusebenza nokucubungula kwe-EDM.Ngesikhathi esifanayo, i-electrode shape (izindonga ezincane, amakhona ayindilinga amancane, izinguquko ezibukhali, njll.) futhi ibeka izidingo eziphezulu kusayizi wokusanhlamvu namandla e-electrode ye-graphite, okuholela ekutheni i-workpiece ye-graphite ijwayele ukuhlukana kanye nethuluzi. gqoka ngesikhathi sokucubungula.
2. Ithuluzi lokugaya i-graphiteimpahla
Izinto zamathuluzi ziyisici esibalulekile esinquma ukusebenza kwethuluzi, okunomthelela omkhulu ekusebenzeni kahle komshini, ikhwalithi, izindleko, nokuqina kwamathuluzi.Lapho into yamathuluzi iqina, kuba ngcono ukumelana kwayo nokugqokwa, ikhulisa ubulukhuni bayo, inciphisa ukuqina kwayo komthelela, kanye nokubola kwempahla.
Ukuqina nokuqina kuyaphikisana futhi kuyindaba esemqoka okufanele izinto zamathuluzi zixazulule.
Ngamathuluzi okusika ama-graphite, i-TIAIN evamile yokumboza ingakhetha izinto ezinokuqina okungcono kakhulu, okungukuthi, lezo ezinokuqukethwe kwe-cobalt ephakeme kancane;Ngamathuluzi okusika ama-graphite anedayimane, izinto ezinobunzima obuphakeme kakhulu, okungukuthi ezinokuqukethwe kwe-cobalt ephansi, zingakhethwa ngokufanelekile.
3. I-engeli ye-geometry yethuluzi
Amathuluzi okusika ama-graphite akhethekileUkukhetha i-engeli yejiyomethri efanele kusiza ekunciphiseni ukudlidliza kwamathuluzi, futhi ngokuphambene, ama-workpieces e-graphite nawo awajwayele ukuphuka.
i-angle yangaphambili
Uma usebenzisa i-engeli ye-rake engalungile ukuze kucutshungulwe i-graphite, amandla onqenqema lwethuluzi mahle, futhi ukumelana komthelela nokusebenza kokungqubuzana kuhle.Njengoba inani eliphelele le-engeli ye-raki enegethivu lincipha, indawo egugile yendawo yethuluzi elingemuva ayishintshi kakhulu, kodwa iyonke ibonisa inkambiso enciphayo.Uma usebenzisa i-engeli ephozithivu ye-rake ukucutshungulwa, njengoba i-engeli ye-rake ikhula, amandla onqenqema lwethuluzi aba buthaka, futhi esikhundleni salokho, ukuguga kwendawo yamathuluzi yangemuva kuyaqiniswa.Uma umshini nge-rake angle engalungile, ukumelana nokusika kuphezulu, okwandisa ukudlidliza kokusika.Lapho kwenziwa imishini nge-engeli enkulu ye-rake, ukugqokwa kwethuluzi kuba nzima, futhi ukudlidliza okusika nakho kuphezulu.
i-angle yokusiza
Uma i-engeli yangemuva inyuka, amandla onqenqema lwethuluzi ayancipha futhi indawo yokuguga yendawo yethuluzi elingemuva iyanda kancane kancane.Uma i-engeli yangemuva yethuluzi inkulu kakhulu, ukudlidliza kokusika kuyanda.
i-helix angle
Uma i-engeli ye-helix incane, ubude bonqenqema lokusika obunqamula ngesikhathi esisodwa ku-workpiece ye-graphite kuzo zonke iziphetho zokusika bude, ukumelana nokusika kuba kukhulu, futhi amandla okusika aphethwe yithuluzi makhulu, okuholela ekugqokeni okukhulu kwamathuluzi. , amandla okugaya, nokudlidliza okusikayo.Uma i-engeli ye-helix inkulu, isiqondiso samandla okugaya sichezuka kakhulu ebusweni bomsebenzi wokusebenza.Umthelela wokusika obangelwa ukuhlukana kwezinto ze-graphite uqinisa ukuguga, futhi umthelela wamandla okugaya kanye nokudlidliza okusika kuyinhlanganisela ye-engeli yangaphambili, i-engeli yangemuva, ne-engeli ye-helix.Ngakho-ke, kuyadingeka ukunaka kakhulu lapho ukhetha.
3.i-end mill ye-graphite enamathela
I-PCD yokusika amathuluzi wokusika zinezinzuzo ezinjengokuqina okuphezulu, ukumelana nokugqokwa okuhle, kanye ne-coefficient ephansi yokungqubuzana.
Njengamanje, ukufakwa kwedayimane kuyisinqumo esingcono kakhulu samathuluzi omshini we-graphite futhi angabonisa kangcono ukusebenza okuphezulu kwamathuluzi e-graphite.Inzuzo yethuluzi le-carbide elihlanganiswe nedayimane ukuthi lihlanganisa ubulukhuni bedayimane lemvelo namandla kanye nokuqina kwe-Fracture ye-carbide.
I-engeli yejiyomethri yamathuluzi ahlanganiswe nedayimane ihluke ngokuyisisekelo kuleyo yezingubo ezijwayelekile.Ngakho-ke, lapho uklama amathuluzi ahlanganiswe nedayimane, ngenxa yemvelo ekhethekile yokucubungula i-graphite, i-engeli yejometri ingakhuliswa ngokufanelekile, futhi i-chip hold groove nayo ingakhuliswa, ngaphandle kokunciphisa ukumelana nokugqoka konqenqema lwamathuluzi.Ngezingubo ezijwayelekile ze-TIAIN, nakuba ukumelana kwazo nokugqoka kuthuthukiswa kakhulu uma kuqhathaniswa namathuluzi angamboziwe, uma kuqhathaniswa nezingubo zedayimane, i-engeli yejometri kufanele yehliswe ngokufanelekile lapho kwenziwa i-graphite ukuze kwandiswe ukumelana kwayo nokugqoka.
4. I-blade passivation
Ubuchwepheshe be-passivation bonqenqemeni luyindaba ebaluleke kakhulu engakaqashelwa kabanzi okwamanje.Ukubaluleka kwalo kulele eqinisweni lokuthi ithuluzi elidlulisiwe lingathuthukisa ngempumelelo amandla onqenqemeni, impilo yamathuluzi, nokuzinza kwenqubo yokusika.Siyazi ukuthi amathuluzi okusika “angamazinyo” wamathuluzi omshini, kanye nezici eziyinhloko ezithinta ukusebenza kokusika nempilo yamathuluzi.Ngaphezu kwento yamathuluzi, ipharamitha yejiyomethri yamathuluzi, ukwakheka kwamathuluzi, ukwenziwa ngcono kwepharamitha, njll., ngokusebenzisa inani elikhulu lezinqubo zokuphasa unqenqema lwamathuluzi, sibonile ukuthi ukuba nefomu elihle lonqenqema kanye nekhwalithi yokudlula unqenqema nakho kuyimfuneko yethuluzi. ukuze ukwazi ukwenza ukucubungula okuhle kokusika.Ngakho-ke, isimo somkhawulo wokusika futhi siyisici esingenakunakwa
5. Indlela yokusika
Ukukhethwa kwezimo zokusika kunomthelela omkhulu empilweni yamathuluzi.
Ukudlidliza okusikayo kokugaya phambili kuncane kunalokho kokugaya okubuyela emuva.Ngesikhathi sokugaya phambili, ukushuba kokusika kwethuluzi kuncipha ukusuka kokuphezulu kuye ku-zero.Ngemuva kokuthi ithuluzi lisike ku-workpiece, ngeke kube khona into ebhampisayo ebangelwa ukungakwazi ukusika ama-chips.Uhlelo lwenqubo lunokuqina okuhle nokudlidliza okuphansi kokusika;Ngesikhathi sokugaya okuphambene, ubukhulu bokusika bethuluzi bukhuphuka busuka ku-zero bufinyelele phezulu.Esigabeni sokuqala sokusika, ngenxa yobukhulu obuncane bokusika, kuzodwetshwa indlela ebusweni bomsebenzi wokusebenza.Ngalesi sikhathi, uma unqenqema luhlangana namaphoyinti aqinile kuzinto ze-graphite noma izinhlayiya ze-chip ezisele ebusweni bomsebenzi, kuzobangela ukuthi ithuluzi libhampa noma lidlidlize, okuholela ekudlidlizeni okubalulekile okusika ngesikhathi sokugaya okuhlanekezelwe.
Ukufutha (noma ukuhlanza) kanye nokucwiliswa kumshini wokukhipha uketshezi kagesi
Ukuhlanzwa ngesikhathi kothuli lwe-graphite endaweni yokusebenza kunenzuzo ekwehliseni ukuguga kwesibili kwamathuluzi, ukwandisa impilo yesevisi yamathuluzi, nokunciphisa umthelela wothuli lwe-graphite kuzikulufu neziqondiso zamathuluzi omshini.
