He aha ka ʻokoʻa ma waena o Sinker EDM a me Wire EDM?
Hoʻohana ʻo Sinker EDM i kahi electrode i hoʻohana ʻia e mīkini i nā lua makapō a me nā geometries kūloko.
Hoʻohana ʻo Wire EDM i kahi uwea e neʻe mau ana e ʻoki i nā mea uila a hoʻohana mua ʻia no nā profiles., Nā Punches, make, a me nā hiʻohiʻona.
No ke aha i hoʻohana mau ʻia ai ka graphite a me ke keleawe e like me nā electrodes EDM?
Hāʻawi nā mea ʻelua i ka conductivity uila maikaʻi a me ka machinability.
Hoʻohana nui ʻia ka Graphite no nā electrodes paʻakikī a me nā noi EDM wela kiʻekiʻe, ʻoiai hiki i ke keleawe ke hāʻawi i nā kikoʻī kikoʻī maikaʻi loa a me ka maikaʻi o ka ʻili i nā kūlana machining kūpono.
Hoʻopilikia anei ʻo EDM i ka ʻili o ka mea hana?
Hoʻopuka ʻo EDM i kahi ʻili wela a hiki ke hana i kahi papa hana hou. Me nā palena hoʻopau hoʻomalu pono ʻia, hiki ke hoemiia ka papa i hoopiliia.
Pono paha nā ʻāpana koʻikoʻi i ka hoʻopau ʻana a i ʻole ka nānā ʻana.
Pehea ka pololei o ka sinker EDM?
Hoʻopaʻa mau nā mīkini EDM sinker kiʻekiʻe i ka hoʻomanawanui ʻana o ± 0.002 a ± 0.005 mm no ka hapa nui o nā hiʻohiʻona, me nā mīkini ultra-precision hiki ke ± 0.001 mm ma lalo o nā kūlana hoʻomalu.
Pili ka pololei i ka paʻa o ka mīkini, ka mālama ʻana i ka mahana a me ka hoʻokele pono ʻana i ke kapa electrode.
Hiki iā Sinker EDM mīkini paʻakikī kila?
ʻAe. Hiki i ka Sinker EDM ke mīkini i nā mea conductive, me ka nānā ʻole i ka paʻakikī. ʻO kēia kekahi o kāna mau pono mua ma mua o ka mīkini maʻamau.
He kumukūʻai ʻo Sinker EDM?
Ka mea paahana (hana electrode) he pipiʻi, a he kumu kūʻai ka manawa mīkini ma muli o ka lohi o ka lawe ʻana i nā mea.
Akā naʻe,, no nā geometries paʻakikī a me nā mea paʻakikī, ʻO Sinker EDM ke koho ʻoi loa ka uku.
