Izinto eziluncedo kwii-electrode zegraphite
I-1: Ubunzima obuninzi bejometri yokubumba kunye nokuhlukahluka kwezicelo zemveliso kuye kwakhokelela kwiimfuno eziphezulu kunye neziphezulu zokuchaneka kokukhutshwa komatshini we-spark. Iingenelo zee-electrode zegraphite kulula ukusetyenzwa, izinga eliphezulu lokususa umatshini wokukhupha umbane, kunye nelahleko ephantsi yegraphite. Ke ngoko, abanye abathengi bomatshini wentlantsi esekwe kwiqela bashiya i-electrode yobhedu kwaye batshintshele kwii-electrode zegraphite. Ukongezelela, ezinye ii-electrode ezikhethekileyo azikwazi ukwenziwa ngobhedu, kodwa i-graphite ilula ukumila, kwaye i-electrodes yobhedu inzima kwaye ayifanelekanga ukusetyenzwa kwee-electrode ezinkulu. Ezi zinto zibangele ukuba abanye abathengi bomatshini we-spark abasekwe kwiqela basebenzise i-electrode yegraphite.
2: I-electrode yegraphite kulula ukuyiqhuba, kwaye isantya sokucubungula sikhawuleza kakhulu kunee-electrode zobhedu. Ngokomzekelo, ukusebenzisa iteknoloji yokugaya ukucubungula igraphite, isantya sayo sokusebenza siphindwe kabini-3 ngokukhawuleza kunomnye ukucubungula isinyithi kwaye ayifuni ukuqhutyelwa kwencwadana eyongezelelweyo, ngelixa i-electrodes yobhedu idinga ukugaya ngesandla. Ngokufanayo, ukuba i-high-speed graphite machining center isetyenziselwa ukuvelisa i-electrode, isantya siya kukhawuleza kwaye ukusebenza kakuhle kuya kuba phezulu, kwaye akuyi kubakho iingxaki zothuli. Kwezi nkqubo, ukukhetha izixhobo ezinobunzima obufanelekileyo kunye negraphite kunokunciphisa ukunxiba kwesixhobo kunye nomonakalo wobhedu. Ukuba uthelekisa ngokuthe ngqo ixesha lokugaya i-electrode yegraphite kunye ne-electrode yobhedu, i-electrode yegraphite i-67% ngokukhawuleza kune-electrode yobhedu. Kumatshini wokukhutshwa kombane ngokubanzi, ukusetyenzwa kwee-electrode zegraphite ngama-58% ngokukhawuleza kunee-electrode zobhedu. Ngale ndlela, ixesha lokucubungula liyancipha kakhulu, kwaye iindleko zokuvelisa nazo ziyancipha.
I-3: Uyilo lwe-electrode yegraphite luhluke kwi-electrode yobhedu yendabuko. Iifektri ezininzi zokungunda zidla ngokuba nezibonelelo ezahlukeneyo zokurhaxa kunye nokugqitywa kwee-electrode zobhedu, ngelixa ii-electrode zegraphite zisebenzisa phantse izibonelelo ezifanayo. Oku kunciphisa inani le-CAD / CAM kunye nokulungiswa komatshini. Ngenxa yesi sizathu kuphela, Kwanele ukuphucula ukuchaneka komgodi wokungunda kwinqanaba elikhulu.
Kakade ke, emva kokuba umzi-mveliso wokungunda utshintshile ukusuka kwi-electrode yobhedu ukuya kwi-electrode yegraphite, into yokuqala efanele icace yindlela yokusebenzisa izinto zegraphite nokuqwalasela ezinye izinto ezinxulumene noko. Kule mihla, abanye abathengi bomatshini wentlantsi esekwe kwiqela basebenzisa igraphite ukukhupha i-electrode machining, ephelisa inkqubo yokugulisa umngxunya wokungunda kunye nokupolishwa kweekhemikhali, kodwa bafezekise umphezulu olindelekileyo. Ngaphandle kokunyusa ixesha kunye nenkqubo yokupolisha, akunakwenzeka ukuba i-electrode yobhedu ivelise umsebenzi onjalo. Ukongeza, igraphite yahlulwe ngokwamabakala ahlukeneyo. Isiphumo esifanelekileyo sokusebenza sinokufezekiswa ngokusebenzisa amabakala afanelekileyo egraphite kunye neeparamitha zokukhutshwa kwentlantsi yombane phantsi kwezicelo ezithile. Ukuba umqhubi usebenzisa iiparitha ezifanayo njenge-electrode yobhedu kumatshini we-spark usebenzisa i-graphite electrode, ngoko umphumo kufuneka udane. Ukuba ufuna ukulawula ngokungqongqo izinto eziphathekayo ze-electrode, unokuseta i-electrode yegraphite kwimeko engalahlekiyo (ilahleko engaphantsi kwe-1%) ngexesha lokucoca kakubi, kodwa i-electrode yobhedu ayisetyenziswanga.
Igraphite inezi mpawu zilandelayo zomgangatho ophezulu ubhedu olungenako ukuhambelana nalo:
isantya processing: high-speed milling machining rough amaxesha 3 ngokukhawuleza kunobhedu; ukugqiba ukugaya ngesantya esiphezulu kumaxesha angama-5 ngokukhawuleza kunobhedu
Ukuchaneka okulungileyo, kunokuqonda imodeli enzima yejometri
Ubunzima bokukhanya, ubuninzi bungaphantsi kwe-1/4 yobhedu, i-electrode kulula ukuyibamba
inokunciphisa inani le-electrode enye, kuba inokudityaniswa kwi-electrode edibeneyo
Uzinzo oluhle lwe-thermal, akukho deformation kwaye akukho burrs processing
