Graphite ndi chinthu chofala kwambiri chosakhala chachitsulo, chakuda, cholimba kutentha kwambiri komanso kotsika, cholimba magetsi ndi kutentha bwino, cholimba mafuta komanso mawonekedwe okhazikika a mankhwala; cholimba magetsi bwino, chingagwiritsidwe ntchito ngati electrode mu EDM. Poyerekeza ndi ma electrode amkuwa achikhalidwe, graphite ili ndi zabwino zambiri monga kulimba kutentha kwambiri, kugwiritsa ntchito pang'ono kutulutsa, komanso kusintha pang'ono kutentha. Imasonyeza kusinthasintha bwino pakukonza molondola komanso zinthu zovuta komanso ma electrode akuluakulu. Pang'onopang'ono yasintha ma electrode amkuwa ngati magetsi. Njira yayikulu yogwiritsira ntchito ma electrode [1]. Kuphatikiza apo, zinthu zosagwira ntchito za graphite zitha kugwiritsidwa ntchito pansi pa liwiro lalikulu, kutentha kwambiri, komanso kuthamanga kwambiri popanda mafuta opaka. Zipangizo zambiri zimagwiritsa ntchito kwambiri ma graphite, ma piston caps, seals and bearing.
Pakadali pano, zipangizo za graphite zimagwiritsidwa ntchito kwambiri m'magawo a makina, zitsulo, makampani a mankhwala, chitetezo cha dziko ndi zina. Pali mitundu yambiri ya ziwalo za graphite, kapangidwe ka ziwalo zovuta, kulondola kwakukulu komanso zofunikira pamtundu wa pamwamba. Kafukufuku wa m'nyumba pa makina opangira graphite si wozama mokwanira. Zipangizo zamakina opangira graphite za m'nyumba nazonso ndi zochepa. Kukonza graphite zakunja kumagwiritsa ntchito malo opangira graphite pokonza mwachangu, komwe tsopano kwakhala njira yayikulu yopangira makina opangira graphite.
Nkhaniyi ikufotokoza makamaka za ukadaulo wopangira graphite ndi zida zogwiritsira ntchito makina kuchokera mbali zotsatirazi.
①Kusanthula kwa magwiridwe antchito a graphite;

Kusanthula magwiridwe antchito a graphite kudula
Graphite ndi chinthu chophwanyika chomwe chili ndi kapangidwe kosiyana. Kudula graphite kumachitika popanga tinthu tating'onoting'ono kapena ufa wosasunthika kudzera mu kusweka kwa graphite. Ponena za njira yodulira zinthu za graphite, akatswiri akunyumba ndi akunja achita kafukufuku wambiri. Akatswiri akunja amakhulupirira kuti njira yopangira graphite chip imachitika pafupifupi pamene m'mphepete mwa chidacho mukhudzana ndi workpiece, ndipo nsonga ya chidacho imaphwanyidwa, ndikupanga tchipisi tating'ono ndi mabowo ang'onoang'ono, ndipo mng'alu umapangidwa, womwe udzafika kutsogolo ndi pansi pa nsonga ya chida, ndikupanga dzenje losweka, ndipo gawo la workpiece lidzasweka chifukwa cha kupita patsogolo kwa chida, ndikupanga tchipisi. Akatswiri akunyumba amakhulupirira kuti tinthu ta graphite ndi topyapyala kwambiri, ndipo m'mphepete mwa chidacho muli nsonga yayikulu, kotero ntchito ya m'mphepete mwa chidacho ndi yofanana ndi extrusion. Zinthu za graphite m'dera lolumikizirana ndi chidacho - workpiece imafinyidwa ndi nkhope ya rake ndi nsonga ya chidacho. Pakukakamizidwa, kusweka kwa brittle kumapangidwa, motero kupanga tchipisi tosweka [3].
Pakudula graphite, chifukwa cha kusintha kwa njira yodulira ya ngodya zozungulira kapena ngodya za workpiece, kusintha kwa kuthamanga kwa chida cha makina, kusintha kwa njira ndi ngodya yodulira mkati ndi kunja kwa chida, kugwedezeka kwa kudula, ndi zina zotero, graphite workpiece imakhudzidwa, zomwe zimapangitsa kuti m'mphepete mwa gawo la graphite likhale lofooka komanso losalimba, kuwonongeka kwakukulu kwa zida ndi mavuto ena. Makamaka pokonza ngodya ndi zigawo za graphite zoonda komanso zopapatiza, nthawi zambiri zimayambitsa ngodya ndi kusweka kwa workpiece, zomwe zakhalanso zovuta pakupanga graphite.
Njira yodulira graphite 
Njira zachikhalidwe zopangira graphite zimaphatikizapo kutembenuza, kugaya, kupukuta, kudula, ndi zina zotero, koma zimatha kungopanga kukonza kwa zigawo za graphite ndi mawonekedwe osavuta komanso osalondola kwenikweni. Ndi chitukuko chachangu ndikugwiritsa ntchito malo opangira graphite othamanga kwambiri, zida zodulira, ndi ukadaulo wothandizira, njira zachikhalidwe zopangira graphite pang'onopang'ono zasinthidwa ndi ukadaulo wopanga mwachangu. Machitidwe awonetsa kuti: chifukwa cha mawonekedwe olimba komanso ofooka a graphite, kuwonongeka kwa zida kumakhala kwakukulu pakukonza, chifukwa chake, tikulimbikitsidwa kugwiritsa ntchito zida zokutidwa ndi carbide kapena diamondi.
Njira zodulira
Chifukwa cha graphite yapadera, kuti pakhale kukonza bwino kwa zigawo za graphite, njira zoyenera ziyenera kutengedwa kuti zitsimikizire. Mukakonza zinthu za graphite, chidacho chimatha kudya mwachindunji pa workpiece, pogwiritsa ntchito magawo akuluakulu odulira; kuti zipewe kusweka pomaliza, zida zomwe zimakhala ndi mphamvu yolimba nthawi zambiri zimagwiritsidwa ntchito kuchepetsa kuchuluka kwa kudula kwa chidacho, ndikuwonetsetsa kuti mtunda wa chida chodulira ndi wochepera theka la mainchesi a chidacho, ndikuchita njira zoyezera monga kuchepetsa processing pokonza mbali zonse ziwiri [4].
Ndikofunikanso kukonza bwino njira yodulira panthawi yodula. Pokonza mawonekedwe amkati, mawonekedwe ozungulira ayenera kugwiritsidwa ntchito momwe angathere kuti adule gawo lamphamvu la gawo lodulidwalo kuti likhale lolimba komanso lolimba nthawi zonse, komanso kuti chogwiriracho chisasweke [5]. Mukakonza mapulaneti kapena mipata, sankhani chakudya chozungulira kapena chozungulira momwe mungathere; pewani zilumba pamalo ogwirira ntchito a gawolo, ndipo pewani kudula chogwirira ntchito pamalo ogwirira ntchito.
Kuphatikiza apo, njira yodulira ndi chinthu chofunikira chomwe chimakhudza kudula kwa graphite. Kugwedezeka kwa kudula panthawi yodulira pansi kumakhala kochepa kuposa kwa kugaya pamwamba. Kukhuthala kwa chida panthawi yodulira pansi kumachepetsedwa kuchoka pamlingo wapamwamba kufika pa zero, ndipo sipadzakhala vuto lodumphadumpha chida chikadula mu workpiece. Chifukwa chake, kugaya pansi nthawi zambiri kumasankhidwa kuti kugwiritsidwe ntchito kwa graphite.
Pokonza zinthu zogwirira ntchito za graphite zokhala ndi zomangamanga zovuta, kuwonjezera pa kukonza ukadaulo wokonza zinthu kutengera zomwe zili pamwambapa, njira zina zapadera ziyenera kutengedwa malinga ndi mikhalidwe yeniyeni kuti mupeze zotsatira zabwino kwambiri zodulira.
