1. MalungaUmsiki wokugaya igraphite
Xa kuthelekiswa nee-electrode zobhedu, ii-electrode zegraphite zineenzuzo ezinjengokusetyenziswa kwe-electrode ephantsi, isantya sokucombulula ngokukhawuleza, ukusebenza kakuhle komatshini, ukuchaneka okuphezulu, ukuguqulwa kwe-thermal encinci, ubunzima obulula, unyango olulula phezu komhlaba, ukumelana nobushushu obuphezulu, ubushushu bokusebenza okuphezulu, kunye nokuncamathela kwe-electrode. .
Nangona i-graphite yinto elula kakhulu ukusika, izinto zegraphite ezisetyenziswe njenge-electrode ye-EDM kufuneka zibe namandla okwaneleyo ukuphepha umonakalo ngexesha lokusebenza kunye nokucutshungulwa kwe-EDM.Kwangaxeshanye, imilo ye-electrode (ebhityileyo, iikona ezincinci ezingqukuva, utshintsho olubukhali, njl.njl.) ikwabeka iimfuno eziphezulu kubungakanani bengqolowa kunye namandla e-electrode yegraphite, ekhokelela ekubeni i-workpiece yegraphite ithande ukuqhekeka kunye nesixhobo. ukunxiba ngexesha lokucubungula.
2. Isixhobo sokugaya igraphiteimpahla
Isixhobo sesixhobo yeyona nto ibalulekileyo emisela ukusebenza kwesixhobo, esinempembelelo enkulu ekusebenzeni kakuhle komatshini, umgangatho, iindleko, kunye nokuqina kwesixhobo.Ukuqina kwesixhobo sesixhobo, kokukhona ukuxhathisa kwayo kunxitywa, kokukhona ukuqina kwayo kuphezulu, kokukhona kusezantsi ukuqina kwayo kwempembelelo, kunye nokuqhekeka kwezinto.
Ukuqina kunye nokuqina kuyaphikisana kwaye ngumba ophambili ekufuneka izixhobo zesixhobo zijongane nazo.
Kwizixhobo zokusika i-graphite, iingubo ze-TIAIN eziqhelekileyo zinokukhetha izixhobo ezinobunzima obungcono, oko kukuthi, ezo zinomxholo ophezulu we-cobalt;Kwizixhobo zokusika i-diamond efakwe kwi-graphite, izixhobo ezinobunzima obuphezulu, oko kukuthi, kunye nomxholo ophantsi we-cobalt, unokukhethwa ngokufanelekileyo.
3. Isixhobo sejiyometri engile
Izixhobo ezikhethekileyo zokusika igraphiteUkukhetha i-engile yejometri efanelekileyo kunceda ekunciphiseni ukungcangcazela kwesixhobo, kwaye ngokuchaseneyo, ii-workpieces zegraphite nazo azikwazi ukuphuka.
i-engile yangaphambili
Xa usebenzisa i-engile yeharibi engalunganga ukusetyenzwa kwegraphite, amandla edge yesixhobo alungile, kunye nokumelana nempembelelo kunye nokusebenza kokukhuhlana kulungile.Njengoko ixabiso elipheleleyo le-engile ye-rake engalunganga liyancipha, indawo yokunxiba yendawo engasemva ayitshintshi kakhulu, kodwa iyonke ibonisa indlela ehlayo.Xa usebenzisa i-engile ye-rake esebenzayo, njengoko i-angle ye-rake isanda, amandla e-edge yesixhobo ayancipha, kwaye endaweni yoko, ukunxiba kwendawo yesixhobo yangasemva kuqiniswa.Xa umatshini nge-rake angle engalunganga, ukuchasana kokusika kuphezulu, oko kwandisa i-vibration yokusika.Xa umatshini nge-angle enkulu ye-rake, isixhobo sokunxiba sinzima, kwaye i-vibration yokusika nayo iphezulu.
i-angle yokukhulula
Ukuba i-angle yangasemva iyanda, amandla omgca wesixhobo ayancipha kwaye indawo yokunxiba yesixhobo sangasemva iyanda ngokuthe ngcembe.Xa i-angle yangasemva yesixhobo ikhulu kakhulu, i-vibration yokusika iyanda.
i-engile ye-helix
Xa i-angle ye-helix incinci, ubude becala lokusika elinqumla ngaxeshanye kwi-workpiece yegraphite kuzo zonke iindawo zokusika zide, ukuxhathisa ukusika kukhulu, kwaye impembelelo yempembelelo yokusika ethwalwa sisixhobo inkulu, kubangele ukunxiba kwesixhobo esikhulu. , amandla okuguba, kunye nokungcangcazela.Xa i-angle ye-helix inkulu, isalathiso samandla okugaya siyaphambuka kakhulu kumphezulu we-workpiece.Impembelelo yokusika ebangelwa ukuqhekeka kwezinto zegraphite iqinisa ukunxiba, kwaye impembelelo yamandla okugaya kunye nokusika i-vibration yindibaniselwano ye-angle yangaphambili, i-angle yangasemva, kunye ne-helix angle.Ngoko ke, kuyimfuneko ukunikela ingqalelo ngakumbi xa ukhetha.
3.isiphelo sokusila segraphite ukutyabeka
Izixhobo zokusika ze-PCD zokubeka zineengenelo ezinje ngobulukhuni obuphezulu, ukumelana nokunxiba kakuhle, kunye ne-coefficient ephantsi yokukhuhlana.
Okwangoku, ukugquma kwedayimani lolona khetho lubalaseleyo lwezixhobo zomatshini zegraphite kwaye zinokubonisa ngcono ukusebenza okuphezulu kwezixhobo zegraphite.I-advanteji yesixhobo se-diamond coated carbide kukuba idibanisa ubulukhuni bedayimane yendalo kunye namandla kunye nokuqina kwe-Fracture ye-carbide.
I-engile yejometri yezixhobo ezigqunywe ngedayimani zihluke ngokusisiseko kwiingubo eziqhelekileyo.Ke ngoko, xa uyila izixhobo ezigqunywe ngedayimane, ngenxa yobume obukhethekileyo bokusingathwa kwegraphite, i-engile yejometri inokwandiswa ngokufanelekileyo, kwaye i-chip yokubamba i-groove nayo inokwandiswa, ngaphandle kokunciphisa ukuxhathisa kokunxiba komphetho wesixhobo.Kwiingubo eziqhelekileyo ze-TIAIN, nangona ukuxhathisa ukunxiba kuphuculwe kakhulu xa kuthelekiswa nezixhobo ezingagqunywanga, xa kuthelekiswa neengubo zedayimani, i-engile yejometri kufuneka incitshiswe ngokufanelekileyo xa kusenziwa igraphite ukuze kwandiswe ukuxhathisa kwayo.
4. I-blade passivation
Itekhnoloji ye-passivation ye-cut edge ngumba obaluleke kakhulu ongekaqatshelwa ngokubanzi okwangoku.Ukubaluleka kwayo kuxhomekeke kwinto yokuba isixhobo esigqithisiweyo sinokuphucula ngokufanelekileyo amandla e-edge, ubomi besixhobo, kunye nokuzinza kwenkqubo yokusika.Siyazi ukuba izixhobo zokusika "ngamazinyo" ezixhobo zoomatshini, kunye nezinto eziphambili ezichaphazela ukusika ukusebenza kunye nobomi besixhobo.Ukongeza kwisixhobo sesixhobo, iiparamitha zejometri yesixhobo, ulwakhiwo lwesixhobo, ukwenziwa ngcono kweparamitha, njl.njl., ngokusebenzisa inani elikhulu leendlela zokugqitha, siye saqonda ukuba ukuba nefomu elungileyo yomphetho kunye nomgangatho wokugqitha kukwayimfuneko kwisixhobo. ukukwazi ukwenza umsebenzi wokusika kakuhle.Ngoko ke, imeko ye-cut edge nayo yinto engenakuhoywa
5. Indlela yokusika
Ukukhethwa kweemeko zokusika kunempembelelo ebalulekileyo kubomi besixhobo.
Ukungcangcazela okusikiweyo kokusila phambili kuncinci kunelo lokusila umva.Ngethuba lokugaya phambili, ukusika kwesixhobo kunciphisa ukusuka kwiqondo eliphezulu ukuya kwi-zero.Emva kokuba isixhobo sinqumle kwi-workpiece, akuyi kubakho into ephazamisayo ebangelwa ukungakwazi ukusika iichips.Inkqubo yenkqubo ine-rigidity elungileyo kunye ne-low cut vibration;Ngexesha lokugaya umva, ukusika kwesixhobo kwandisa ukusuka kwi-zero ukuya kubuninzi.Kwinqanaba lokuqala lokusika, ngenxa yobunzima obuncinci bokusika, umendo uya kutsalwa phezu kwendawo yokusebenza.Ngeli xesha, ukuba umgca wokusika udibana namanqaku anzima kwizinto zegraphite okanye i-chip particles eseleyo kumphezulu we-workpiece, iya kubangela ukuba isixhobo siqhume okanye singcangcazele, okubangele ukugungqa okubalulekileyo ngexesha lokugaya.
Ukuvuthela (okanye ukutshayela) kunye nokuntywiliselwa kumatshini wokukhutshwa kombane
Ukucocwa ngexesha lothuli lwegraphite kumphezulu womsebenzi kunenzuzo ekunciphiseni ukunxiba kwesixhobo sesibini, ukwandisa ubomi benkonzo yesixhobo, kunye nokunciphisa impembelelo yothuli lwegraphite kwizikrufu zesixhobo somatshini kunye nezikhokelo.
