Graphite ndi wamba sanali zitsulo chuma, wakuda, ndi mkulu ndi otsika kutentha kukana, wabwino magetsi ndi matenthedwe madutsidwe, lubricity wabwino ndi khalidwe khola mankhwala; magetsi abwino, amatha kugwiritsidwa ntchito ngati electrode mu EDM. Poyerekeza ndi maelekitirodi amkuwa amkuwa, ma graphite ali ndi zabwino zambiri monga kukana kutentha kwambiri, kutsika kwamadzi otulutsa, komanso kupunduka kwakung'ono kwamafuta. Imawonetsa kusinthika bwino pakukonza magawo olondola komanso ovuta komanso ma elekitirodi akulu akulu. Pang'onopang'ono yalowa m'malo mwa maelekitirodi amkuwa ngati zowala zamagetsi. Kuchuluka kwa ma electrode opanga makina [1]. Kuphatikiza apo, zida zolimbana ndi ma graphite zimatha kugwiritsidwa ntchito mothamanga kwambiri, kutentha kwambiri, komanso kupanikizika kwambiri popanda mafuta opaka mafuta. Zida zambiri zimagwiritsa ntchito makapu a pistoni a graphite, zisindikizo ndi mayendedwe
Pakali pano, zipangizo graphite chimagwiritsidwa ntchito m'minda ya makina, zitsulo, makampani mankhwala, chitetezo dziko ndi zina. Pali mitundu yambiri ya zigawo za graphite, mawonekedwe ovuta, kulondola kwapamwamba komanso zofunikira zapamwamba. Kafukufuku wapakhomo pa makina a graphite siwozama mokwanira. Zida zamakina opangira ma graphite apanyumba nawonso ndi ochepa. Kukonza ma graphite akunja makamaka kumagwiritsa ntchito malo opangira ma graphite kuti azitha kuthamanga kwambiri, zomwe tsopano zakhala njira yayikulu yopangira ma graphite Machining.
Nkhaniyi imayang'ana kwambiri ukadaulo wa graphite Machining ndi zida zamakina opangira zinthu kuchokera kuzinthu zotsatirazi.

Kusanthula magwiridwe antchito a graphite
Graphite ndi chinthu chosasunthika chokhala ndi mawonekedwe osasinthika. Graphite kudula zimatheka ndi kupanga discontinuous Chip particles kapena ufa kudzera Chimaona fracture wa graphite zakuthupi. Ponena za njira yodulira zida za graphite, akatswiri kunyumba ndi kunja achita kafukufuku wambiri. Akatswiri akunja amakhulupirira kuti graphite chip mapangidwe ndondomeko ndi pafupifupi pamene kudula m'mphepete mwa chida kukhudzana ndi workpiece, ndi nsonga ya chida waphwanyidwa, kupanga tchipisi tating'ono ndi maenje ang'onoang'ono, ndipo A crack amapangidwa, amene adzawonjezera. kutsogolo ndi pansi pa chida nsonga, kupanga mng'oma dzenje, ndi gawo la workpiece adzakhala wosweka chifukwa chida kupita patsogolo, kupanga tchipisi. Akatswiri apakhomo amakhulupirira kuti tinthu tating'onoting'ono ta graphite ndiabwino kwambiri, ndipo m'mphepete mwa chidacho chimakhala ndi nsonga yayikulu, motero ntchito yodulira ndiyofanana ndi extrusion. Zida za graphite zomwe zili pamalo olumikizirana ndi chida - chogwirira ntchito chimafinyidwa ndi nkhope yopangira ndi nsonga ya chida. Pansi pa kukakamizidwa, brittle fracture imapangidwa, motero kupanga tchipisi tating'onoting'ono [3].
M'kati mwa kudula graphite, chifukwa cha kusintha kwa njira kudula kwa ngodya zozungulira kapena ngodya za workpiece, kusintha kwa mathamangitsidwe a chida cha makina, kusintha kwa njira ndi ngodya ya kudula mkati ndi kunja kwa chida, kudula kugwedezeka. , etc., kukhudzidwa kwina kumayambika ku graphite workpiece, zomwe zimapangitsa m'mphepete mwa gawo la graphite. Kuwonongeka kwapakona ndi kupukuta, kuvala kwambiri zida ndi mavuto ena. Makamaka pokonza ngodya ndi mbali zowonda komanso zopapatiza za graphite, zimatha kuyambitsa ngodya ndi kupukuta kwa workpiece, zomwe zakhalanso zovuta kupanga ma graphite.
Graphite kudula ndondomeko 
Njira zamakono zopangira zida za graphite zimaphatikizapo kutembenuza, mphero, kugaya, kucheka, ndi zina zotero, koma amatha kuzindikira kukonzedwa kwa magawo a graphite ndi mawonekedwe osavuta komanso otsika kwambiri. Ndi chitukuko chofulumira ndi kugwiritsa ntchito malo opangira makina othamanga kwambiri a graphite, zida zodulira, ndi matekinoloje ogwirizana nawo, njira zamakina zachikhalidwe izi zasinthidwa pang'onopang'ono ndi umisiri wothamanga kwambiri. Zochita zawonetsa kuti: chifukwa cha mawonekedwe olimba komanso osasunthika a graphite, kuvala kwa zida kumakhala kovuta kwambiri pakukonza, chifukwa chake, tikulimbikitsidwa kugwiritsa ntchito zida zokutira za carbide kapena diamondi.
Kudula njira miyeso
Chifukwa chapadera cha graphite, kuti mukwaniritse kukonza kwapamwamba kwa magawo a graphite, njira zofananira ziyenera kuchitidwa kuti zitsimikizire. Pamene roughing graphite zakuthupi, chida akhoza mwachindunji kudya workpiece, ntchito ndi lalikulu kwambiri kudula magawo; pofuna kupewa kutsetsereka pakumaliza, zida zokhala ndi kukana kwabwino nthawi zambiri zimagwiritsidwa ntchito kuti muchepetse kuchuluka kwa chidacho, ndikuwonetsetsa kuti phula la chida chodulira ndi losakwana 1/2 la mainchesi a chida, ndikuchita ndondomeko. miyeso monga deceleration processing pamene kukonza mapeto onse [4].
M'pofunikanso kukonzekera bwino njira yodulira panthawi yodula. Pokonza mkombero wamkati, mizere yozungulira iyenera kugwiritsidwa ntchito momwe mungathere kuti muchepetse mphamvu ya gawo lodulidwa kuti likhale lolimba komanso lamphamvu, ndikuletsa chogwirira ntchito kuti chisaswe [5]. Mukamakonza ndege kapena ma grooves, sankhani chakudya cha diagonal kapena spiral 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 kodula pa mphero kumakhala kochepa poyerekeza ndi mphero. Kudula makulidwe a chida pa mphero pansi kumachepetsedwa kuchokera pazipita mpaka ziro, ndipo sipadzakhala chodabwitsa chodabwitsa chikadula chidacho. Choncho, mphero pansi nthawi zambiri amasankhidwa kuti apange graphite.
Pamene pokonza workpieces graphite ndi nyumba zovuta, kuwonjezera kukhathamiritsa luso processing zochokera maganizo pamwamba, miyeso ena apadera ayenera kumwedwa malinga ndi mikhalidwe yeniyeni kuti tikwaniritse bwino kudula zotsatira.
