I-graphite iyinto evamile engeyona eyensimbi, emnyama, enokumelana nokushisa okuphezulu nokuphansi, ukuqhutshwa okuhle kukagesi nokushisa, ukuthambisa okuhle nezici zamakhemikhali ezizinzile;conductivity kagesi enhle, ingasetshenziswa njenge-electrode ku-EDM.Uma kuqhathaniswa nama-electrode ethusi endabuko, i-graphite inezinzuzo eziningi ezifana nokumelana nokushisa okuphezulu, ukusetshenziswa okuphansi kokukhipha, kanye nokuguqulwa okuncane kokushisa.Ibonisa ukuguquguquka okungcono ekucubungulweni kokunemba kanye nezingxenye eziyinkimbinkimbi kanye nama-electrode anosayizi omkhulu.Kancane kancane iye yashintsha ama-electrode ethusi njengezinhlansi zikagesi.Okujwayelekile kwama-electrodes machining [1].Ukwengeza, izinto ezikwazi ukumelana nokugqoka kwe-graphite zingasetshenziswa ngaphansi kwezimo zejubane eliphezulu, izinga lokushisa eliphezulu, nokucindezela okukhulu ngaphandle kwamafutha okugcoba.Imishini eminingi isebenzisa kabanzi izinkomishi ze-piston ezibonakalayo ze-graphite, izimpawu nama-bearings
Njengamanje, izinto ze-graphite zisetshenziswa kabanzi emkhakheni wemishini, i-metallurgy, imboni yamakhemikhali, ukuvikela kazwelonke neminye imikhakha.Kunezinhlobo eziningi zezingxenye ze-graphite, ukwakheka kwezingxenye eziyinkimbinkimbi, ukunemba okuphezulu kwe-dimensional kanye nezidingo zekhwalithi ephezulu.Ucwaningo lwasekhaya mayelana ne-graphite machining alujulile ngokwanele.Amathuluzi omshini wokucubungula i-graphite wasekhaya nawo mancane uma kuqhathaniswa.Ukucutshungulwa kwe-graphite kwamanye amazwe ikakhulukazi kusebenzisa izikhungo zokucubungula i-graphite zokucubungula ngesivinini esikhulu, manje osekuyisiqondiso esiyinhloko sokuthuthukiswa kwe-graphite machining.
Lesi sihloko sihlaziya kakhulu ubuchwepheshe be-graphite machining kanye namathuluzi omshini wokucubungula kusuka kuzici ezilandelayo.
①Ukuhlaziywa kokusebenza kwe-graphite machining;
② Izinyathelo zobuchwepheshe bokucubungula i-graphite ezivame ukusetshenziswa;

Ukuhlaziywa kokusebenza kwe-graphite
I-graphite iyimpahla ephukayo enesakhiwo esihlukile.Ukusika i-graphite kufinyelelwa ngokukhiqiza izinhlayiya ze-chip ezingaqhubeki noma impushana ngokuphuka kwe-brittle yezinto ze-graphite.Mayelana nendlela yokusika yezinto ze-graphite, izazi zasekhaya nakwamanye amazwe zenze ucwaningo oluningi.Izazi zakwamanye amazwe zikholelwa ukuthi inqubo yokwakheka kwe-graphite chip icishe ifane lapho unqenqema lwethuluzi luthintana ne-workpiece, futhi ichopho lethuluzi lichotshozwa, lenze ama-chips amancane nemigodi emincane, bese kukhiqizwa i-A crack, ezonweba. ngaphambili nangaphansi kwephuzu lethuluzi, ukwakha umgodi wokuphuka, futhi ingxenye ye-workpiece izophulwa ngenxa yokuthuthuka kwethuluzi, ukwakha ama-chips.Izazi zasekhaya zikholelwa ukuthi izinhlayiya ze-graphite zihle kakhulu, futhi umkhawulo wokusika wethuluzi une-arc enkulu ye-tip, ngakho-ke indima yokusika ifana ne-extrusion.Izinto zegraphite endaweni yokuxhumana yethuluzi - isiqeshana somsebenzi sikhanywa ubuso beraki kanye nesihloko sethuluzi.Ngaphansi kwengcindezi, i-brittle fracture ikhiqizwa, ngaleyo ndlela yakhe ama-chips chips [3].
Enqubweni yokusika i-graphite, ngenxa yezinguquko endleleni yokusika yamakhona ayindilinga noma amakhona e-workpiece, izinguquko ekusheshiseni kwethuluzi lomshini, izinguquko endleleni kanye ne-angle yokusika ngaphakathi nangaphandle kwethuluzi, ukusika ukudlidliza. , njll., umthelela othile ubangelwa umsebenzi we-graphite, okuholela emaphethelweni engxenye yegraphite.Ukuqina kwekhona nokuqhekeka, ukuguga kwamathuluzi okunzima nezinye izinkinga.Ikakhulukazi lapho ucubungula amakhona kanye nezingxenye zegraphite ezizacile nezinezimbambo eziwumngcingo, kungenzeka ukuthi kubangele amakhona kanye nokuchotshozwa kwendawo yokusebenza, okubuye kube nzima ekwenzeni i-graphite machining.
Inqubo yokusika i-graphite 
Izindlela zendabuko zemishini yezinto ze-graphite zihlanganisa ukuphenduka, ukugaya, ukugaya, ukusika, njll., kodwa bangakwazi ukubona kuphela ukucutshungulwa kwezingxenye ze-graphite ezinobunjwa obulula nokunemba okuphansi.Ngokuthuthuka okusheshayo kanye nokusetshenziswa kwezikhungo zemishini ze-graphite ezinesivinini esikhulu, amathuluzi okusika, nobuchwepheshe obusekelayo obuhlobene, lezi zindlela zemishini zendabuko ziye zathathelwa indawo ubuchwepheshe bemishini bejubane eliphezulu.Ukuzijwayeza kubonise ukuthi: ngenxa yezici eziqinile neziqinile zegraphite, ukugqoka kwamathuluzi kuyingozi kakhulu ngesikhathi sokucubungula, ngakho-ke, kunconywa ukusebenzisa amathuluzi ahlanganiswe ne-carbide noma idayimane.
Izinyathelo zenqubo yokusika
Ngenxa yobuchwepheshe be-graphite, ukuze kuzuzwe ukucubungula okuphezulu kwezingxenye ze-graphite, izinyathelo zenqubo ehambisanayo kufanele zithathwe ukuze kuqinisekiswe.Lapho roughing graphite impahla, ithuluzi kungaba ngqo ukondla workpiece, usebenzisa imingcele ukusika kuqhathaniswa ezinkulu;ukuze ugweme ukuqoshwa ngesikhathi sokuqedwa, amathuluzi anokumelana nokugqokwa okuhle avame ukusetshenziselwa ukunciphisa inani lokusika lethuluzi, futhi Uqinisekise ukuthi iphimbo lethuluzi lokusika lingaphansi kwe-1/2 yobubanzi bethuluzi, futhi wenze inqubo. izinyathelo ezinjengokucubungula ukusheshisa lapho kucutshungulwa zombili iziphetho [4].
Kuyadingeka futhi ukuhlela ngendlela efanele indlela yokusika ngesikhathi sokusika.Lapho kucutshungulwa i-contour yangaphakathi, i-contour ezungezile kufanele isetshenziswe ngangokunokwenzeka ukusika ingxenye yamandla yengxenye esikiwe ukuze ihlale ishubile futhi iqine, futhi kuvinjwe ucezu lokusebenza ukuthi lungaphuli [5].Lapho ucubungula izindiza noma ama-grooves, khetha i-diagonal noma i-spiral feed ngangokunokwenzeka;gwema iziqhingi endaweni yokusebenza yengxenye, futhi ugweme ukusika i-workpiece endaweni yokusebenza.
Ngaphezu kwalokho, indlela yokusika nayo iyisici esibalulekile esithinta ukusika kwe-graphite.Ukudlidliza okusika ngesikhathi sokugaya kungaphansi kwalokho kokugaya phezulu.Ubukhulu bokusika bethuluzi ngesikhathi sokugaya phansi buyancishiswa ukusuka kokuphezulu kuye ku-zero, futhi ngeke kube khona into ebhampishayo ngemuva kokuthi ithuluzi lisike endaweni yokusebenza.Ngakho-ke, ukugaya phansi ngokuvamile kukhethelwa ukucutshungulwa kwe-graphite.
Lapho ucubungula ama-workpieces e-graphite anezakhiwo eziyinkimbinkimbi, ngaphezu kokuthuthukisa ubuchwepheshe bokucubungula ngokusekelwe kulokhu okucatshangelwayo okungenhla, ezinye izinyathelo ezikhethekile kufanele zithathwe ngokuvumelana nezimo ezithile ukuze kuzuzwe imiphumela engcono kakhulu yokusika.
