Kodi ubwino ndi kuipa kwa ma electrode a graphite ndi kotani poyerekeza ndi ma electrode achitsulo achikhalidwe?

Ubwino

1. Liwiro la Machining Mofulumira
   Ma electrode a graphite amapereka liwiro lotha kutulutsira zinthu zotayira nthawi ziwiri kapena zitatu kuposa ma electrode amkuwa, makamaka pokonza ma electrode a thin-rib. Ndi kukana kudula kwa 1/5 yokha kuposa kwa mkuwa, graphite imalola kuti ntchito yokonza zinthu ikhale yogwira mtima kwambiri ndipo imachepetsa kwambiri nthawi yokonza.

2. Wopepuka
   Graphite ili ndi kuchuluka kwa 1/5 kokha kuposa mkuwa, zomwe zimachepetsa katundu pa zida zamakina ndikuchepetsa kuwonongeka kwa zida, zomwe zimapangitsa kuti ikhale yoyenera kwambiri pa nkhungu zazikulu ndi ma electrode.

3. Kuchuluka kwa Kutentha Kotsika
   Kuchuluka kwa kutentha kwa graphite ndi 1/30 yokha kuposa mkuwa, zomwe zimapangitsa kuti pakhale kusintha kochepa panthawi yopangira zinthu zotentha kwambiri komanso kusunga kulondola kwakukulu kwa makina, makamaka pa nthiti zozama, zopapatiza komanso mbali zopyapyala.

4. Zovala Zochepa
   Pa nthawi yotulutsa madzi, maatomu a kaboni mu dielectric fluid amawonongeka kutentha kwambiri ndikupanga filimu yoteteza pamwamba pa graphite electrode, zomwe zimapangitsa kuti ma electrode awonongeke. Mosiyana ndi zimenezi, ma electrode amkuwa nthawi zambiri amapanga ma burrs, zomwe zimafuna kumalizidwa ndi manja.

5. Yopanda Burr komanso Yosavuta Kuipukuta
   Ma electrode a graphite sasiya ma burrs akatha kupangidwa, zomwe zimapangitsa kuti pasakhale kufunikira kokonza zinthu pambuyo pake komanso kuthandizira kupanga zinthu zokha. Kuphatikiza apo, kukana kwawo kudula pang'ono kumathandiza kupukuta ndi kupukuta.

6. Yotsika Mtengo
   Chifukwa cha kukwera kwa mitengo ya mkuwa m'zaka zaposachedwa, ma electrode a graphite akadali okhazikika pamtengo. Komanso, ma electrode a graphite ndi otsika mtengo ndi 30%–60% kuposa ma electrode amkuwa omwe ali ndi voliyumu yomweyo.

7. Magwiridwe Abwino Kwambiri Pakutentha Kwambiri
   Ma electrode a grafiti ali ndi kutentha kwa sublimation mpaka 3650°C, komwe kumaposa kwambiri kusungunuka kwa mkuwa (1083°C), kuonetsetsa kuti zinthu zikuyenda bwino m'malo otentha kwambiri komanso kuti zigwiritsidwe ntchito popanga zinthu pogwiritsa ntchito mphamvu zambiri.

8. Wapamwamba pa Machining Complex Shapes
   Ma electrode a grafiti amapangidwa mosavuta kukhala ma geometries ovuta, kukwaniritsa zofunikira za nkhungu zolondola komanso ziwalo zosawoneka bwino, pomwe ma electrode amkuwa amakumana ndi zovuta zazikulu pakupanga mawonekedwe ovuta.

Zoyipa

1. Mphamvu Yotsika ya Makina
   Ma electrode a graphite ali ndi mphamvu yochepa yamakina, zomwe zimapangitsa kuti azing'ambika m'makona akuthwa, makamaka panthawi yokonza zinthu mopanda dongosolo. Kudula pang'ono komwe kumakhala ndi kuchuluka kwa chakudya kumafunika kuti pasakhale kusweka kapena kusweka kwa ngodya.

2. Kupanga Fumbi
   Ma electrode a graphite opangira makina amapanga fumbi lalikulu, zomwe zimapangitsa kuti pakhale njira zapadera zotsekera ndi kuchotsa fumbi kuti ateteze thanzi la zida zamakina ndi ogwiritsa ntchito.

3. Kugwira Ntchito Koyipa mu Wire EDM
   Mu makina odulira mawaya (Wire EDM), ma electrode a graphite amawonetsa liwiro lodulira pafupifupi 40% pang'onopang'ono kuposa ma electrode amkuwa ndipo amatha kusweka mawaya, zomwe zimapangitsa kuti asagwiritsidwe ntchito podulira mawaya molondola kwambiri.

4. Zolepheretsa Kukhwima Pamwamba
   Kukwaniritsa milingo yolimba pamwamba pansi pa VDI12 (Ra0.4μm) n'kovuta ndi ma electrode a graphite. Pa makina otulutsira zinthu pogwiritsa ntchito galasi, ma electrode amkuwa amakhalabe chisankho chabwino.

5. Kuvuta Pobwezeretsanso Zinthu
   Zidutswa za ma electrode a graphite zili ndi mtengo wotsika wobwezeretsanso zinthu ndipo zimakhala zovuta kuzigwiritsanso ntchito, zomwe zimawonjezera ndalama zogwiritsira ntchito komanso zimakhudza chilengedwe.

6. Kusalimba ndi Kusakhazikika kwa Kusweka kwa Mphuno
   Ma electrode a grafiti ndi ofooka, makamaka ma electrode owonda kapena opapatiza, omwe amatha kusweka ndi mphamvu zakunja, zomwe zimafuna kusamalidwa mosamala.

7. Sizoyenera Kukonza Machining Otulutsa Madzi Pamwamba Pang'ono
   Pa makina otulutsira madzi pang'ono pamwamba omwe amafuna kuti pamwamba pakhale pansi pa VDI12 (Ra0.4μm), ma electrode a graphite sagwira ntchito bwino poyerekeza ndi ma electrode amkuwa, zomwe zimapangitsa kuti zikhale zovuta kukwaniritsa zofunikira zapamwamba pamwamba.
