M'zaka zaposachedwapa, ndi ntchito yaikulu ya nkhungu graphite, pachaka mowa mtengo wa zisamere pachakudya mu makampani makina ndi 5 nthawi okwana mtengo wa mitundu yonse ya zida makina, ndi imfa yaikulu kutentha ndi yosiyana kwambiri ndi mphamvu alipo. -kupulumutsa ndondomeko ku China.The mowa waukulu wa zisamere pachakudya osati mwachindunji kumawonjezera mtengo wa mabizinezi, komanso kumabweretsa pafupipafupi kupanga mzere shutdowns chifukwa pafupipafupi m'malo zisamere pachakudya, potsiriza kuchititsa imfa yaikulu zachuma.
Malinga ndi kafukufuku, chifukwa nkhungu zopangira ndi mphamvu mitengo ananyamuka kwambiri ndi zifukwa zina, ndi nkhungu makampani mankhwala phindu anagwa chaka chatha; Kuti apulumuke ndi kukhala, mabizinesi ambiri kutengera
Kusintha kwazinthu kumagwiritsidwa ntchito ngati njira yayikulu yosinthira ndi chitukuko. Zimamveka kuti makampani ambiri adayambitsa zida zotulutsa ma graphite spark, mukupanga nkhungu ikuchita gawo lofunikira kwambiri. Poyerekeza ndi nkhungu zamkuwa zamkuwa, zinthu za graphite zili ndi zabwino zambiri Machining mwatsatanetsatane ndi zotsatira zabwino pamwamba, makamaka mu nkhungu patsekeke processing mwatsatanetsatane, zovuta, khoma woonda, mkulu zinthu zolimba ali advantage.Poyerekeza ndi mkuwa, graphite zakuthupi ali ndi ubwino monga kumwa mochepa, mofulumira kukhetsa liwiro, kulemera kuwala ndi zazing'ono. matenthedwe kukulitsa coefficient, kotero mkuwa elekitirodi pang'onopang'ono wakhala waukulu wa kumaliseche processing materials.Mosiyana, graphite elekitirodi zipangizo ali ndi ubwino zisanu ndi chimodzi zotsatirazi:
1. Kuthamanga kwachangu; Kutulutsa kwa graphite ndikothamanga kwambiri 2-3 kuposa mkuwa, ndipo zinthu sizili zophweka kuti ziwonongeke.Iwo ali ubwino zoonekeratu pokonza woonda analimbitsa elekitirodi.Kufewetsa kwa mkuwa kuli pafupifupi madigiri 1000, ndipo ndikosavuta kupunduka chifukwa cha kutentha.
2. Kulemera kopepuka;Kuchulukana kwa graphite ndi 1/5 yokha ya mkuwa.Pamene electrode yaikulu ikukonzedwa ndi kutulutsa, katundu wa chida cha makina (EDM) akhoza kuchepetsedwa bwino, omwe ali oyenera kugwiritsa ntchito nkhungu yaikulu.
3. Kuwonongeka kwakung'ono; Monga mafuta a spark ali ndi maatomu a C, kutentha kwakukulu kumapangitsa kuti maatomu a C mu mafuta a spark awonongeke panthawi yotulutsa utsi, ndipo filimu yotetezera imapangidwa pamwamba pa electrode ya graphite, yomwe imabwezera kutaya kwa electrode ya graphite.
4. Palibe ma burrs; Pambuyo pokonza electrode yamkuwa, ma burrs ayenera kuchotsedwa pamanja.Komabe, palibe ma burrs pambuyo pa kukonzedwa kwa graphite, zomwe sizimangopulumutsa ndalama zambiri ndi ogwira ntchito, komanso zimapangitsa kuti zikhale zosavuta kuzindikira kupanga.
5. Kupukuta kosavuta; Chifukwa kukana kudula kwa graphite ndi 1/5 yokha ya mkuwa, ndikosavuta kugaya ndi kupukuta ndi dzanja.
Vi.Mtengo wotsika; Chifukwa cha kukwera mtengo kwa mkuwa m'zaka zaposachedwa, mtengo wa graphite m'mbali zonse ndi wotsika kuposa wamkuwa. Pansi pa voliyumu yomweyi ya chilengedwe cha Oriental carbon, mtengo wa zinthu za graphite ndi 30% mpaka 60% kuposa. kuti yamkuwa, mtengo wake ndi wokhazikika, ndipo kusinthasintha kwanthawi kochepa kwamitengo kumakhala kochepa.Ndi kusungirako mphamvu, kuteteza chilengedwe ndi kukonza bwino kudzakhala cholinga cha makampani opanga zinthu, zipangizo za graphite electrode zidzalowa pang'onopang'ono m'malo mwa elekitirodi yamkuwa ndikusewera yofunika kwambiri. udindo mu EDM. Mofananamo, mumpikisano wowonjezereka kwambiri pamsika wa nkhungu masiku ano, kugwiritsa ntchito zipangizo zamakono zamakono kuti apange mankhwala apamwamba a nkhungu ndiyo njira yabwino kwambiri yopangira malonda kuti apambane msika ndi makasitomala.
