Graphite yakajairika isiri-metallic material, dema, ine yakakwirira uye yakaderera tembiricha kuramba, yakanaka magetsi uye thermal conductivity, yakanaka lubricity uye yakagadzikana makemikari maitiro;yakanaka conductivity yemagetsi, inogona kushandiswa se electrode muEDM.Kuenzaniswa nemagetsi emhangura echinyakare, graphite ine zvakawanda zvakanaka senge tembiricha yekudzivirira, kuderera kwekuburitsa, uye diki deformation yekupisa.Inoratidza zviri nani kuchinjika mukugadzirisa kweiyo chaiyo uye yakaoma zvikamu uye yakakura-saizi maelectrode.Yakatsiva zvishoma nezvishoma ma electrode emhangura semapfava emagetsi.Iyo huru yekugadzira ma electrode [1].Mukuwedzera, magirafu asingagadziri zvinhu zvinogona kushandiswa pasi pekumhanya-mhanya, kutonhora kwepamusoro, uye kudzvinyirira kwakanyanya pasina mafuta ekuzora.Midziyo mizhinji inoshandisa zvakanyanya graphite zvinhu piston makapu, zvisimbiso uye mabhengi
Parizvino, magirafu zvinhu zvinoshandiswa zvakanyanya muminda yemichina, simbi, indasitiri yemakemikari, kudzivirira kwenyika uye mamwe minda.Kune akawanda marudzi ezvikamu zvegraphite, akaomeswa zvikamu zvimiro, yakakwirira dimensional kurongeka uye pamusoro pemhando zvinodiwa.Tsvagiridzo yemumba nezve graphite machining haina kudzika zvakakwana.Domestic graphite processing machine maturusi zvakare mashoma.Kune dzimwe nyika kugadzirisa magirafu kunonyanya kushandisa nzvimbo dzekugadzira magirafu epamusoro-kumhanya, iyo yave ikozvino ndiyo huru yekusimudzira nzira yegraphite machining.
Ichi chinyorwa chinonyanya kuongorora tekinoroji yegraphite machining uye maturusi emuchina wekugadzira kubva kune zvinotevera zvinhu.
① Ongororo ye graphite machining performance;
② Inowanzo shandiswa graphite kugadzirisa tekinoroji zviyero;
③ Zvishandiso zvinowanzo shandiswa uye kucheka paramita mukugadzirisa graphite;
Graphite yekucheka maitiro ekuongorora
Graphite chinhu chine brittle chine heterogeneous chimiro.Graphite kucheka kunowanikwa nekugadzira discontinuous chip particles kana upfu kuburikidza ne brittle fracture ye graphite material.Nezve magadzirirwo ekucheka kwezvinhu zvegraphite, nyanzvi dzekumba nekune dzimwe nyika dzakaita tsvakiridzo yakawanda.Nyanzvi dzekune dzimwe nyika dzinotenda kuti iyo graphite chip yekugadzira maitiro inosvika pakuchekwa kwechishandiso ichibatana neiyo workpiece, uye muromo wechombo unopwanyika, kugadzira machipisi madiki nemakomba madiki, uye A crack inogadzirwa, inozowedzera. kumberi uye kuzasi kwechishandiso tipi, kugadzira gomba rekutsemuka, uye chikamu chebasa chinoputswa nekuda kwekufambira mberi kwechishandiso, kugadzira machipisi.Nyanzvi dzemudzimba dzinotenda kuti ma graphite particles akanyanya kunaka, uye kucheka kwechishandiso kune yakakura tip arc, saka basa rekucheka rakafanana neextrusion.Iyo graphite zvinhu munzvimbo yekusangana yechishandiso - iyo workpiece inosvinwa nereki kumeso uye muromo wechishandiso.Pasi pekumanikidzwa, brittle fracture inogadzirwa, nekudaro ichigadzira chipping chips [3].
Mukuita kwekucheka kwegraphite, nekuda kwekuchinja munzira yekucheka yemakona akatenderedzwa kana makona echishandiso, shanduko mukukwidziridzwa kwechishandiso chemuchina, shanduko munzira uye kona yekucheka mukati nekunze kwechishandiso, kucheka vibration. , nezvimwewo, kumwe kukanganiswa kunokonzerwa kune girafu workpiece, zvichiita kuti kumucheto kwechikamu chegirafu.Corner brittleness uye chipping, yakanyanya kupfeka maturusi uye mamwe matambudziko.Kunyanya kana uchigadzira makona uye dzakatetepa uye dzakamanikana-ribbed-ribbed graphite zvikamu, zvinowanzoitika kukonzeresa makona uye kucheka kweiyo workpiece, iyo yave zvakare yakaoma mukugadzira graphite.
Graphite yekucheka maitiro 
Iwo echinyakare machining maitiro ezvigadzirwa zvegraphite anosanganisira kutenderedza, kugaya, kukuya, kusaha, nezvimwewo, asi ivo vanogona chete kuona kugadziriswa kwezvikamu zvegraphite zvine maumbirwo akareruka uye kushomeka kwakadzika.Nekukurumidza kusimudzira uye kushandiswa kwemagraphite akakwira-kumhanya machining nzvimbo, maturusi ekucheka, uye ane hukama anotsigira matekinoroji, idzi nzira dzechinyakare dzemuchina dzakatsiviwa zvishoma nezvishoma neanomhanya-mhanya matekinoroji.Kudzidzira kwakaratidza kuti: nekuda kwekuoma uye brittle maitiro e graphite, kushandiswa kwezvishandiso kunonyanya kuoma panguva yekugadzirisa, saka, zvinokurudzirwa kushandisa carbide kana diamond coated tools.
Kucheka maitiro matanho
Nekuda kwekusarudzika kwegraphite, kuti uwane yepamusoro-yemhando yekugadzirisa yezvikamu zvegraphite, inoenderana maitiro matanho anofanirwa kutorwa kuve nechokwadi.Kana gadziriso graphite zvinyorwa, chishandiso chinogona kupa zvakananga pabasa rekushanda, vachishandisa ma parmeter akakura anocheka;kuitira kudzivirira kucheka panguva yekupedzisa, maturusi ane zvakanaka kupfeka kuramba anowanzo shandiswa kudzikisa huwandu hwekucheka kwechishandiso, uye Ita shuwa kuti nhanho yechishandiso chekucheka iri pasi pe1/2 yedhayamita yechishandiso, uye kuita maitiro. zviyero zvakadai sekuderedza kugadzirisa paunenge uchigadzirisa magumo ose [4].
Izvo zvinodiwawo kuronga zvinonzwisisika nzira yekucheka panguva yekucheka.Paunenge uchigadzira iyo yemukati contour, iyo yakatenderedza contour inofanirwa kushandiswa zvakanyanya sezvinobvira kucheka simba chikamu chechikamu chakachekwa kuti chigare chakakora uye chakasimba, uye kudzivirira workpiece kubva pakuputsika [5].Paunenge uchigadzira ndege kana grooves, sarudza diagonal kana spiral feed zvakanyanya sezvinobvira;dzivisa zvitsuwa pamusoro pebasa rekushanda kwechikamu, uye dzivisa kucheka workpiece panzvimbo yekushanda.
Mukuwedzera, nzira yekucheka zvakare chinhu chinokosha chinokanganisa girafu yekucheka.Kudengenyeka kwekucheka panguva yekugaya kudiki pane kwekukwira kumusoro.Ukobvu hwekucheka kwechishandiso panguva yekugaya pasi hunoderedzwa kubva pahupamhi kusvika ku zero, uye hapazove nekubvongodza chiitiko mushure mekunge chishandiso chacheka mukati mechishandiso.Naizvozvo, kugaya pasi kunowanzo kusarudzirwa graphite kugadzirisa.
Paunenge uchigadzira graphite workpieces ane yakaoma zvimiro, mukuwedzera kune optimize tekinoroji yekugadzira zvichibva pane zviri pamusoro apa, mamwe matanho akakosha anofanirwa kutorwa zvinoenderana nemamiriro chaiwo kuti uwane yakanakisa yekucheka mhedzisiro.
