Makhalidwe a electrode yathu ya graphite

Makhalidwe athuelectrode ya graphite:

1. Mitengo yokhazikika komanso yoyenera:

Mtengo wa zinthu za graphite umangofunika 15% ya voliyumu yomweyo ya elekitirodi yamkuwa.Pakalipano, graphite yakhala chinthu chodziwika bwino cha ntchito za EDM, zotsika mtengo komanso zokhazikika poyerekeza ndi zipangizo za graphite.

1. Kudula ndi kukonza kosavuta
2. 4. Opepuka komanso otsika kachulukidwe
3. Kuchulukana kwa graphite nthawi zambiri kumakhala 1.7-1.9g / cm3 (mkuwa ndi 4-5 nthawi ya graphite).Poyerekeza ndi maelekitirodi amkuwa, ma electrode a graphite amachepetsa katundu wamakina panthawiyi.Ndizoyenera kwambiri kupaka nkhungu zazikulu.
4. 5. Good kudula processing
5. Poyerekeza ndi zipangizo zachitsulo, voliyumu ya graphite yapangidwa kuti ikhale yochepa.Iwo ali kwambiri makina processing ntchito.
6. 6. Kugwirizana kwenikweni
7. Inki ya miyala imatha kulumikizidwa kudzera pa zomatira, zomwe zimapulumutsa nthawi ndi ndalama zakuthupi.
8. 7. Kupambana kwakukulu
9. The resistivity (ER) imatsimikizira kukana kwa zinthu zomwe zikuyenda pakalipano.A m'munsi resistivity zikutanthauza madutsidwe.

Graphite ali ndi zida zabwino kwambiri zopangira makina.Kuthamanga kwa makina a maelekitirodi a graphite ndi 2-3 nthawi zambiri kuposa maelekitirodi amkuwa.Panthawi imodzimodziyo, palibe chifukwa chodandaula za burrs pambuyo pokonza graphite.

3. Coefficient yowonjezera yowonjezera kutentha

Malo osungunuka a mkuwa ndi 1080 ℃, pamene CTE ya graphite ndi 1/30 yokha yamkuwa pa 3650 ℃.Imakhala ndi ntchito yokhazikika ngakhale pa kutentha kotentha.Ngakhale pokonza ma elekitirodi a platinamu, ma elekitirodi a graphite ali ndi zabwino zambiri.
