Pali zifukwa zambiri zopangira zida za graphite elekitirodi, koma pali njira zinayi zazikulu:
1. The pafupifupi tinthu awiri a zakuthupi
The pafupifupi tinthu awiri a zinthu mwachindunji zimakhudza kumaliseche udindo wa zinthu.
Zing'onozing'ono za tinthu tating'onoting'onoting'onoting'onoting'onoting'onoting'ono tazinthuzo, zimakhala zofanana kwambiri ndi kutayika kwazinthuzo, kutulutsa kokhazikika, komanso khalidwe lapamwamba.
Popanga ndi kufa-kuponyera zisankho zokhala ndi zofunikira zochepa komanso zolondola, nthawi zambiri zimalimbikitsidwa kugwiritsa ntchito tinthu tating'onoting'ono, monga ISEM-3, ndi zina;kwa zisa kuumba pakompyuta ndi pamwamba ndi zofunika mwatsatanetsatane, Ndi bwino kugwiritsa ntchito zipangizo ndi pafupifupi tinthu kukula m'munsimu 4μm.
Kuonetsetsa kulondola ndi pamwamba mapeto a nkhungu kukonzedwa.
Zing'onozing'ono za kukula kwa tinthu tating'onoting'ono, kutayika kochepa kwa zinthu, komanso mphamvu yaikulu pakati pa magulu a ion.
Mwachitsanzo, ISEM-7 nthawi zambiri imalimbikitsidwa kuti ipange zisankho zolondola komanso zopangira.Komabe, makasitomala akakhala ndi zofunika kwambiri mwatsatanetsatane, tikulimbikitsidwa kugwiritsa ntchito zida za TTK-50 kapena ISO-63 kuti zitsimikizire kutaya kwazinthu zochepa.
Onetsetsani kuti nkhunguyo ili yolondola komanso yolimba.
Nthawi yomweyo, tinthu tating'onoting'ono tinthu tating'onoting'ono tomwe timatulutsa mwachangu komanso zazing'onoting'ono zimatayika.
Chifukwa chachikulu ndi chakuti mphamvu zamakono zomwe zimapangidwira zimakhala zosiyana, zomwe zimabweretsa mphamvu zosiyana siyana.
Koma pamwamba mapeto pambuyo kumaliseche amasintha ndi kusintha kwa particles.
2. Flexural mphamvu zakuthupi
Mphamvu ya flexural ya chinthu ndi chiwonetsero chachindunji cha mphamvu ya zinthu, kusonyeza kulimba kwa mkati mwa zinthuzo.
Zida zamphamvu kwambiri zimakhala ndi ntchito yabwino yokana kutulutsa.Kwa maelekitirodi omwe ali ndi zofunikira zolondola kwambiri, yesani kusankha zida zolimba kwambiri.
Mwachitsanzo: TTK-4 akhoza kukwaniritsa zofunika zimaumba ambiri cholumikizira pakompyuta, koma ena zisamere pachakudya cholumikizira pakompyuta ndi zofunika mwatsatanetsatane mwatsatanetsatane, mukhoza kugwiritsa ntchito tinthu zofanana kukula koma apamwamba pang'ono mphamvu zakuthupi TTK-5.
3. Kuuma kwa gombe kwa zinthu
Pakumvetsetsa kwa graphite, graphite nthawi zambiri imawonedwa ngati chinthu chofewa.
Komabe, deta yeniyeni yoyesera ndi zochitika zogwiritsira ntchito zimasonyeza kuti kuuma kwa graphite ndikwapamwamba kuposa zipangizo zachitsulo.
M'makampani apadera a graphite, muyeso wa kuuma kwapadziko lonse lapansi ndi njira yoyezera kuuma kwa M'mphepete mwa nyanja, ndipo mfundo yake yoyesera ndiyosiyana ndi zitsulo.
Chifukwa cha mawonekedwe osanjikiza a graphite, imakhala ndi ntchito yabwino kwambiri yodulira panthawi yodula.Mphamvu yodulira ndi pafupifupi 1/3 yokha ya zida zamkuwa, ndipo pamwamba pakupanga makina ndikosavuta kugwira.
Komabe, chifukwa cha kuuma kwake kwakukulu, chida chovala panthawi yodula chidzakhala chachikulu pang'ono kuposa zida zodulira zitsulo.
Panthawi imodzimodziyo, zipangizo zomwe zimakhala ndi kuuma kwakukulu zimakhala ndi mphamvu zowonongeka zowonongeka.
Mu dongosolo lathu lazinthu za EDM, pali zipangizo ziwiri zomwe tingasankhe pazitsulo za kukula kwa tinthu tating'ono zomwe zimagwiritsidwa ntchito mobwerezabwereza, zomwe zimakhala zovuta kwambiri ndipo zina zimakhala ndi zovuta zochepa kuti zikwaniritse zosowa za makasitomala omwe ali ndi zofunikira zosiyanasiyana.
kufuna.
Mwachitsanzo: zipangizo ndi pafupifupi tinthu kukula 5μm monga ISO-63 ndi TTK-50;zipangizo ndi pafupifupi tinthu kukula 4μm monga TTK-4 ndi TTK-5;zipangizo ndi pafupifupi tinthu kukula 2μm monga TTK-8 ndi TTK-9.
Makamaka poganizira zokonda zamitundu yosiyanasiyana yamakasitomala kutulutsa magetsi ndi makina.
4. The intrinsic resistivity wa zinthu
Malingana ndi ziwerengero za kampani yathu pa makhalidwe a zipangizo, ngati tinthu tating'ono tating'ono tating'ono tating'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'onoting'ono.
Pazinthu zomwe zimakhala ndi kukula kwa tinthu tating'onoting'ono, zida zokhala ndi mphamvu zochepa zokhala ndi mphamvu zochepa komanso zolimba kuposa zida zokhala ndi resistivity yayikulu.
Ndiko kuti, kuthamanga ndi kutayika kudzakhala kosiyana.
Choncho, ndikofunika kwambiri kusankha zipangizo malinga ndi zosowa zenizeni.
Chifukwa chapadera cha zitsulo za ufa, gawo lililonse la mtanda uliwonse lili ndi kusinthasintha kwapadera kwa mtengo wake woimira.
Komabe, zotsatira za kutulutsidwa kwa zipangizo za graphite za kalasi imodzi ndizofanana kwambiri, ndipo kusiyana kwa zotsatira zogwiritsira ntchito chifukwa cha magawo osiyanasiyana ndizochepa kwambiri.
Kusankhidwa kwa zinthu za electrode kumagwirizana mwachindunji ndi zotsatira za kutulutsa.Pamlingo waukulu, ngati kusankha kwa zinthuzo kuli koyenera kumatsimikizira mkhalidwe womaliza wa liwiro la kutulutsa, kulondola kwa makina ndi kuuma kwa pamwamba.
Mitundu inayi ya datayi imayimira ntchito yayikulu yotulutsa zinthuzo ndikudziwitsa mwachindunji momwe zinthuzo zikuyendera.
