I-Graphite iyinto evamile engeyona eyensimbi, emnyama, enokumelana nokushisa okuphezulu nokuphansi, ukuhanjiswa kahle kukagesi nokushisa, ukuthambisa okuhle kanye nezici zamakhemikhali ezizinzile; ukuhanjiswa kahle kukagesi okuhle, ingasetshenziswa njenge-electrode ku-EDM. Uma kuqhathaniswa nama-electrode ethusi endabuko, i-graphite inezinzuzo eziningi njengokumelana nokushisa okuphezulu, ukusetshenziswa okuphansi kokukhipha, kanye nokuguquguquka okuncane kokushisa. Ibonisa ukuzivumelanisa nezimo okungcono ekucutshungulweni kwezingxenye ezinembile neziyinkimbinkimbi kanye nama-electrode amakhulu. Kancane kancane ithathe indawo yama-electrode ethusi njengezinhlansi zikagesi. Okuyinhloko yama-electrode omshini [1]. Ngaphezu kwalokho, izinto ezingagugi ze-graphite zingasetshenziswa ngaphansi kwezimo zesivinini esiphezulu, izinga lokushisa eliphezulu, kanye nengcindezi ephezulu ngaphandle kokugcoba uwoyela. Imishini eminingi isebenzisa kakhulu izinkomishi ze-piston, izivalo nama-bearings ezinto ze-graphite.
Njengamanje, izinto ze-graphite zisetshenziswa kabanzi emikhakheni yemishini, i-metallurgy, imboni yamakhemikhali, ukuvikela izwe kanye neminye imikhakha. Kunezinhlobo eziningi zezingxenye ze-graphite, isakhiwo sezingxenye esiyinkimbinkimbi, ukunemba okuphezulu kanye nezidingo zekhwalithi yobuso. Ucwaningo lwasekhaya mayelana nomshini wokugaya i-graphite alujulile ngokwanele. Amathuluzi omshini wokugaya i-graphite wasekhaya nawo mancane kakhulu. Ukucubungula i-graphite yangaphandle kusebenzisa kakhulu izikhungo zokucubungula i-graphite ukuze kucutshungulwe ngesivinini esikhulu, manje esesiyindlela eyinhloko yokuthuthukiswa komshini wokugaya i-graphite.
Lesi sihloko sihlaziya kakhulu ubuchwepheshe bokubumba i-graphite kanye namathuluzi omshini wokucubungula kusukela kulezi zici ezilandelayo.
①Ukuhlaziywa kokusebenza komshini we-graphite;
② Izindlela zobuchwepheshe bokucubungula i-graphite ezisetshenziswa kakhulu;
③ Amathuluzi avame ukusetshenziswa kanye nemingcele yokusika ekucubunguleni i-graphite;
Ukuhlaziywa kokusebenza kokusika i-graphite
I-Graphite iyinto ephukile enesakhiwo esingafani. Ukusikwa kwe-Graphite kufezwa ngokukhiqiza izinhlayiya ze-chip ezingaguquki noma i-powder ngokuqhekeka okuphukile kwezinto ze-graphite. Ngokuphathelene nendlela yokusika izinto ze-graphite, izazi zasekhaya nakwamanye amazwe zenze ucwaningo oluningi. Izazi zakwamanye amazwe zikholelwa ukuthi inqubo yokwakheka kwe-graphite chip icishe ibe lapho unqenqema lokusika lwethuluzi luthintana nomsebenzi, futhi isihloko sethuluzi sichotshozwa, kwakha ama-chip amancane nemigodi emincane, bese kukhiqizwa uqhekeko, oluzodlulela phambili nangaphansi kwesihloko sethuluzi, kwakha umgodi wokuqhekeka, futhi ingxenye yomsebenzi izophulwa ngenxa yokuthuthuka kwethuluzi, kwakha ama-chip. Izazi zasekhaya zikholelwa ukuthi izinhlayiya ze-graphite zinhle kakhulu, futhi unqenqema lokusika lwethuluzi lune-arc enkulu yesihloko, ngakho-ke indima yonqenqema lokusika ifana nokukhipha. Izinto ze-graphite endaweni yokuxhumana yethuluzi - umsebenzi ucindezelwa ubuso be-rake kanye nesihloko sethuluzi. Ngaphansi kwengcindezi, kukhiqizwa ukuqhekeka okuphukile, ngaleyo ndlela kwakha ama-chip chips [3].
Enkambisweni yokusika i-graphite, ngenxa yezinguquko endleleni yokusika yamakhona ayindilinga noma amakhona ento yokusebenza, izinguquko ekusheshiseni kwethuluzi lomshini, izinguquko endleleni kanye ne-engeli yokusika ngaphakathi nangaphandle kwethuluzi, ukudlidliza kokusika, njll., kubangwa umthelela othile kunto yokusebenza ye-graphite, okuholela onqenqemeni lwengxenye ye-graphite. Ukuphuka kwamakhona nokuqhekeka, ukuguguleka okukhulu kwamathuluzi nezinye izinkinga. Ikakhulukazi lapho kusetshenzwa amakhona nezingxenye ze-graphite ezincane nezincane, kungenzeka kakhulu ukuthi kubangele amakhona nokuqhekeka kwento yokusebenza, okubuye kwaba yinkinga ekusetshenzisweni kwe-graphite.
Inqubo yokusika i-graphite 
Izindlela zendabuko zokugaya izinto ze-graphite zifaka phakathi ukujika, ukugaya, ukugaya, ukusaha, njll., kodwa zingasebenza kuphela ekucubungulweni kwezingxenye ze-graphite ngezimo ezilula kanye nokunemba okuphansi. Ngokuthuthuka okusheshayo nokusetshenziswa kwezikhungo zokugaya ezisheshayo ze-graphite, amathuluzi okusika, kanye nobuchwepheshe obuhambisanayo obuhambisanayo, lezi zindlela zendabuko zokugaya ziye zathathelwa indawo kancane kancane ubuchwepheshe bokugaya obusheshayo. Umkhuba ukhombisile ukuthi: ngenxa yezici eziqinile nezibuthakathaka ze-graphite, ukuguguleka kwamathuluzi kubi kakhulu ngesikhathi sokucubungula, ngakho-ke, kunconywa ukusebenzisa amathuluzi ambozwe nge-carbide noma ngedayimane.
Izindlela zokusika inqubo
Ngenxa yokubaluleka kwe-graphite, ukuze kufezwe ukucutshungulwa kwezingxenye ze-graphite ezisezingeni eliphezulu, kumele kuthathwe izinyathelo zenqubo ezihambisanayo ukuqinisekisa. Lapho kucutshungulwa izinto ze-graphite, ithuluzi lingadla ngqo ku-workpiece, kusetshenziswa amapharamitha okusika amakhulu kakhulu; ukuze kugwenywe ukuqhekeka ngesikhathi sokuqeda, amathuluzi anokumelana okuhle nokuguguleka avame ukusetshenziswa ukunciphisa inani lokusika lethuluzi, futhi aqinisekise ukuthi ukuphakama kwethuluzi lokusika kungaphansi kwe-1/2 yobubanzi bethuluzi, futhi enze izinyathelo zenqubo ezifana nokucubungula ukusheshisa lapho kucutshungulwa zombili iziphetho [4].
Kuyadingeka futhi ukuhlela ngendlela efanele indlela yokusika ngesikhathi sokusika. Lapho kucutshungulwa uhlaka lwangaphakathi, uhlaka oluzungezile kufanele lusetshenziswe ngangokunokwenzeka ukusika ingxenye yamandla yengxenye enqunyiwe ukuze ihlale ijiyile futhi iqine, nokuvimbela ingxenye yokusebenza ukuthi ingaphuki [5]. Lapho kucutshungulwa amapulani noma imifantu, khetha ukudla okuqondile noma okujikelezayo ngangokunokwenzeka; gwema iziqhingi ebusweni bokusebenza bengxenye, futhi ugweme ukusika ingxenye yokusebenza ebusweni bokusebenza.
Ngaphezu kwalokho, indlela yokusika nayo iyisici esibalulekile esithinta ukusika kwe-graphite. Ukudlidliza kokusika ngesikhathi sokugaya phansi kungaphansi kwalokho kokugaya phezulu. Ubukhulu bokusika kwethuluzi ngesikhathi sokugaya phansi buncishisiwe kusukela ku-maximum kuya ku-zero, futhi ngeke kube khona into yokugxuma ngemva kokuba ithuluzi lisike endaweni yokusebenza. Ngakho-ke, ukugaya phansi ngokuvamile kukhethwa ukuze kucutshungulwe i-graphite.
Lapho kucutshungulwa izingcezu zomsebenzi ze-graphite ezinezakhiwo eziyinkimbinkimbi, ngaphezu kokuthuthukisa ubuchwepheshe bokucubungula ngokusekelwe ezintweni ezicatshangelwe ngenhla, kumele kuthathwe izinyathelo ezithile ezikhethekile ngokwemibandela ethile ukuze kutholakale imiphumela emihle kakhulu yokusika.
