Iimpawu ze-electrode yethu yegraphite

Iimpawu zethui-electrode yegraphite:

1. Amaxabiso azinzileyo nafanelekileyo:

Ixabiso lezinto zegraphite zifuna kuphela i-15% yomthamo ofanayo we-electrode yobhedu. Okwangoku, i-graphite ibe yinto eyaziwayo kwizicelo ze-EDM, kunye neendleko eziphantsi kunye nokuzinza ngakumbi xa kuthelekiswa nezixhobo zegraphite.

1. Ukusika ngokulula kunye nokusebenza
2. 4. Ubunzima kunye nobuninzi obuphantsi
3. Ubuninzi begraphite budla ngokuba yi-1.7-1.9g/cm3 (ubhedu ngama-4-5 amaxesha egraphite). Xa kuthelekiswa ne-electrode yethusi, i-electrode yegraphite iya kunciphisa umthwalo womatshini ngexesha le nkqubo. Kufanelekile ngakumbi ukusebenzisa ii-molds ezinkulu.
4. 5. Ukulungiswa kakuhle kokusika
5. Xa kuthelekiswa nezixhobo zetsimbi, umthamo wegraphite wenzelwe ukuba uphantsi. Inomsebenzi obalaseleyo wokulungisa oomatshini.
6. 6. Umphumela wokudibanisa
7. I-inki yeGravel inokudityaniswa nge-adhesive, egcina ixesha kunye neendleko zempahla.
8. 7. Ukuxhathisa okuphezulu
9. I-resistantivity (ER) inquma ukuchasana kwezinto eziphathekayo ukuhamba kwangoku. Ukuxhathisa okuphantsi kuthetha ukuqhuba.

Igraphite ineempawu ezibalaseleyo zokulungisa oomatshini. Isantya somatshini we-electrode yegraphite ngamaxesha angama-2-3 aphezulu kunee-electrode zethusi. Ngexesha elifanayo, akukho mfuneko yokukhathazeka malunga ne-burrs emva kokulungiswa kwegraphite.

3. I-coefficient yokwandisa i-thermal ephantsi

Indawo yokunyibilika kobhedu yi-1080 ℃, ngelixa i-CTE yegraphite iyi-1/30 kuphela yobhedu kwi-3650 ℃. Inomsebenzi ozinzile kakhulu nakwiqondo lokushisa elifudumeleyo. Naxa kusenziwa iplatinum electrode, iielectrode zegraphite zineengenelo ezibalulekileyo.
