1. ZaGraphite mphero wodula
Poyerekeza ndi maelekitirodi amkuwa, ma elekitirodi a graphite ali ndi zabwino monga kugwiritsa ntchito ma electrode otsika, kuthamanga kwachangu, kukonza makina, kulondola kwapang'onopang'ono, mapindikidwe ang'onoang'ono amafuta, kulemera kopepuka, chithandizo chosavuta cha pamwamba, kukana kutentha kwambiri, kutentha kwambiri, komanso kumatira kwamagetsi. .
Ngakhale kuti graphite ndi zinthu zomwe zimakhala zosavuta kudula, ma graphite omwe amagwiritsidwa ntchito ngati electrode ya EDM ayenera kukhala ndi mphamvu zokwanira kuti asawonongeke panthawi ya ntchito ndi EDM processing.Pa nthawi yomweyi, mawonekedwe a elekitirodi (wochepa thupi, ngodya zazing'ono zozungulira, kusintha kwakuthwa, etc.) amaikanso zofunika kwambiri pa kukula kwa tirigu ndi mphamvu ya electrode ya graphite, zomwe zimapangitsa kuti graphite workpiece ikhale yosavuta kugawanika ndi chida. kuvala panthawi ya processing.
2. Chida cha mphero cha graphitezakuthupi
Chidacho ndichofunikira kwambiri chomwe chimatsimikizira momwe chidacho chikugwirira ntchito, chomwe chimakhudza kwambiri luso la makina, mtundu, mtengo, komanso kulimba kwa zida.Chidacho chikavuta kwambiri, chimapangitsa kuti chisawonongeke, chimapangitsa kuti chikhale cholimba kwambiri, chimachepetsa kulimba kwake, komanso kuphulika kwake.
Kulimba ndi kulimba ndizotsutsana komanso nkhani yofunika kwambiri yomwe zida za zida ziyenera kuthana nazo.
Pazida zodulira ma graphite, zokutira wamba za TIAIN zimatha kusankha zida zolimba kwambiri, ndiye kuti, zokhala ndi cobalt wokwera pang'ono;Kwa zida za diamondi zokutira graphite, zida zolimba kwambiri, mwachitsanzo, zokhala ndi cobalt zochepa, zitha kusankhidwa moyenera.
3. Chida cha geometry angle
Zida zapadera zodulira ma graphiteKusankha ngodya yoyenera ya geometric kumathandiza kuchepetsa kugwedezeka kwa zida, ndipo kumbali inayo, zogwirira ntchito za graphite sizimakonda kusweka.
mbali yakutsogolo
Mukamagwiritsa ntchito ngodya yoyipa pokonza graphite, mphamvu ya m'mphepete mwa chida ndi yabwino, komanso kukana kwamphamvu komanso kuchita masewera olimbitsa thupi ndizabwino.Pamene mtengo wamtundu wa negative rake angle ukuchepa, malo ovala a chida chakumbuyo sikusintha kwambiri, koma zonse zikuwonetsa kuchepa.Mukamagwiritsa ntchito ngodya yabwino kuti muthe kukonza, pomwe mbali yake imachulukira, mphamvu ya m'mphepete mwa chida imafooka, ndipo m'malo mwake, kukhathamira kwa chida chakumbuyo kumakulirakulira.Mukamapanga ndi ngodya yolakwika, kukana kudula kumakhala kwakukulu, komwe kumawonjezera kugwedezeka kodula.Mukapanga makina okhala ndi ngodya yayikulu, chidacho chimakhala cholimba, komanso kugwedezeka kwake kumakhala kwakukulu.
angle yothandizira
Ngati mbali yakumbuyo ikuwonjezeka, mphamvu ya m'mphepete mwa chida imachepa ndipo malo ovala a chida chakumbuyo akuwonjezeka pang'onopang'ono.Pamene mbali yakumbuyo ya chidayo ndi yayikulu kwambiri, kugwedezeka kumawonjezeka.
ngodya ya helix
Pamene ngodya ya helix ndi yaying'ono, kutalika kwa m'mphepete mwake komwe kumadula nthawi imodzi muzitsulo za graphite pamphepete zonse zodula kumakhala kotalika, kukana kudula kumakhala kwakukulu, ndipo mphamvu yodulira yomwe imatengedwa ndi chida imakhala yaikulu, zomwe zimapangitsa kuti pakhale kuvala kwakukulu kwa zida. , mphamvu ya mphero, ndi kugwedeza kwamphamvu.Pamene ngodya ya helix ndi yaikulu, mayendedwe a mphamvu ya mphero amapatuka kwambiri kuchokera pamwamba pa workpiece.Kudula komwe kumachitika chifukwa cha kugawanika kwa zinthu za graphite kumawonjezera kuvala, ndipo mphamvu ya mphero ndi kugwedeza kwamphamvu kumaphatikiza mbali yakutsogolo, ngodya yakumbuyo, ndi ngodya ya helix.Choncho, m'pofunika kumvetsera kwambiri posankha.
3.mapeto a graphite zokutira
Zida zodulira zokutira za PCD ali ndi maubwino monga kuuma kwakukulu, kukana bwino kuvala, komanso kugundana kocheperako.
Pakadali pano, zokutira za diamondi ndiye njira yabwino kwambiri yopangira zida za graphite ndipo imatha kuwonetsa bwino magwiridwe antchito apamwamba a zida za graphite.Ubwino wa zida za diamondi zokutira carbide ndikuti zimaphatikiza kuuma kwa diamondi yachilengedwe ndi mphamvu komanso kulimba kwa Fracture kwa carbide.
Makona a geometric a zida zokutira diamondi ndizosiyana kwambiri ndi zokutira wamba.Chifukwa chake, popanga zida zokutira za diamondi, chifukwa cha mawonekedwe apadera a graphite processing, ngodya ya geometric imatha kukulitsidwa moyenera, ndipo poyambira yokhala ndi chip imathanso kukulitsidwa, osachepetsa kukana kwa chida.Kwa zokutira wamba za TIAIN, ngakhale kuti kukana kwawo kuvala kumakhala bwino kwambiri poyerekeza ndi zida zosaphimbidwa, poyerekeza ndi zokutira za diamondi, ngodya ya geometric iyenera kuchepetsedwa moyenera popanga ma graphite kuti awonjezere kukana kwake.
4. Blade passivation
The passivation luso la kudula m'mphepete ndi nkhani yofunika kwambiri kuti si ambiri anazindikira panobe.Kufunika kwake kwagona pa mfundo yakuti chida passivated akhoza bwino kusintha mphamvu m'mphepete, moyo chida, ndi bata ndondomeko kudula.Tikudziwa kuti zida zodulira ndi "mano" a zida zamakina, ndi zinthu zazikulu zomwe zimakhudza ntchito yodula komanso moyo wa zida.Kuwonjezera zida zakuthupi, zida geometric magawo, chida dongosolo, kudula chizindikiro kukhathamiritsa, etc., kudzera chiwerengero chachikulu cha zida m'mphepete passivation zochita, tazindikira kuti kukhala ndi m'mphepete bwino mawonekedwe ndi m'mphepete passivation khalidwe ndi chofunikanso kuti chida. kuti athe kuchita bwino kudula processing.Choncho, chikhalidwe cha kudula ndi chinthu chomwe sichikhoza kunyalanyazidwa
5. Njira yodulira
Kusankhidwa kwa zinthu zodula kumakhudza kwambiri moyo wa chida.
Kugwedezeka kwa mphero yakutsogolo ndikocheperako kuposa mphero yobwerera kumbuyo.Pa mphero yopita patsogolo, makulidwe odula a chida amachepa kuchokera pazipita mpaka ziro.Chidacho chikang'ambika mu workpiece, sipadzakhala chodabwitsa chifukwa cha kulephera kudula tchipisi.The ndondomeko dongosolo ali olimba wabwino ndi otsika kudula kugwedera;Pa mphero mobwerera, makulidwe odula a chida amawonjezeka kuchokera ku ziro mpaka pamlingo waukulu.Mu gawo loyambirira la kudula, chifukwa cha makulidwe ang'onoang'ono odulidwa, njira idzakokera pamwamba pa chogwirira ntchito.Panthawi imeneyi, ngati kudula m'mphepete kukumana mfundo zovuta graphite zakuthupi kapena otsalira Chip particles pamwamba pa workpiece, izo zidzachititsa chida bounce kapena kunjenjemera, chifukwa chachikulu kudula kugwedera pa n'zosiyana mphero.
Kuwomba (kapena vacuuming) ndi kumizidwa mu makina amadzimadzi otulutsa magetsi
Kuyeretsa nthawi yake kwa fumbi la graphite pamwamba pa chogwiriracho ndi kopindulitsa kuchepetsa kuvala kwa zida zachiwiri, kutalikitsa moyo wautumiki wa zida, komanso kuchepetsa mphamvu ya fumbi la graphite pamakina ndi maupangiri.
