He aha ka PDC bit Cutter?

ʻO Diamond ka mea paʻakikī loa i ʻike ʻia. Hāʻawi kēia paʻakikī i nā waiwai maikaʻi no ka ʻoki ʻana i nā mea ʻē aʻe. He mea koʻikoʻi ka PDC (Polycrystalline diamond compact) i ka wili ʻana no ka mea e hōʻuluʻulu ʻo ia i nā daimana liʻiliʻi liʻiliʻi, kūʻai ʻole, i hana ʻia e ke kanaka i loko o ka nui, intergrown nui o nā kristal i hoʻonohonoho pono ʻole ʻia i hiki ke hana ʻia i mau ʻano pono i kapa ʻia nā papa daimana. ʻO nā papa daimana ka ʻāpana o ka mea ʻoki e pili ana i kahi hoʻokumu. Ma waho aʻe o ko lākou paʻakikī, loaʻa i nā papa daimana PDC kahi hiʻohiʻona koʻikoʻi no nā mea ʻoki drill-bit: hoʻopaʻa maikaʻi lākou me nā mea tungsten carbide hiki ke hoʻopaʻa ʻia (hoʻopili ʻia) i nā kino bit. ʻAʻole hiki ke hoʻopaʻa ʻia nā daimana ma o lākou iho, ʻaʻole hoʻi e hoʻopili ʻia e ka brazing.

daimana synthetic

Hoʻohana pinepine ʻia ka daimana e wehewehe i nā kīʻaha liʻiliʻi (≈0.00004 in.) o ke daimana synthetic i hoʻohana ʻia ma ke ʻano he kī nui no nā mea ʻoki PDC. Ma ke ʻano o nā kemika a me nā waiwai, ua like ke daimana i hana ʻia me ke daimana maoli. ʻO ka hana ʻana i ka daimana kaʻina hana maʻalahi: ua wela ke kalapona maʻamau ma lalo o ke kaomi kiʻekiʻe a me ka wela. I ka hoʻomaʻamaʻa naʻe, ʻaʻole maʻalahi ka hana ʻana i ke daimana.

ʻO nā kristal daimana pākahi i loko o ka daimana grit he ʻano like ʻole. ʻO kēia ka mea i ikaika, ʻoi aku ka ikaika, a no ka paʻakikī o ke daimana i loko, ʻaʻole hiki ke ʻaʻahu. ʻO ka ʻoiaʻiʻo, ʻoi aku ka maikaʻi o ka hana maʻamau i loaʻa i loko o nā daimana synthetic i hoʻopaʻa ʻia ma ka ʻako ʻana ma mua o nā daimana maoli, no ka mea, ʻo nā daimana maoli he mau kristal cubic e haki maʻalahi ma ko lākou mau palena crystalline.

ʻAʻole paʻa ka paʻa o ka daimana ma nā mahana kiʻekiʻe ma mua o nā daimana maoli. No ka mea, ʻoi aku ka nui o ka hoʻonui ʻana o ka wela ma mua o ke daimana, ka hoʻonui ʻokoʻa e waiho i nā kaula daimana-a-daimana ma lalo o ke ʻoki ʻana, a inā he kiʻekiʻe nā ukana, e hāʻule. Inā hāʻule nā ​​paʻa, nalowale koke nā daimana, no laila, nalowale ka PDC i kona paʻakikī a me ka ʻoi a lilo i mea ʻole. No ka pale ʻana i kēlā hemahema, pono e hoʻomaʻalili maikaʻi nā mea ʻoki PDC i ka wā wili.

Nā papa ʻaina daimana

No ka hana ʻana i ka papaʻaina daimana, ua hoʻopaʻa ʻia ka daimana grit me ka tungsten carbide a me ka mea hoʻopaʻa metala e hana i kahi papa waiwai daimana. He ʻano wafer lākou, a pono e hana ʻia e like me ka mānoanoa e like me ka mea hiki ke hoʻonui ʻia ka nui o ke daimana. ʻO nā papa daimana kiʻekiʻe loa he ≈2 a 4 mm, a ʻo ka holomua ʻenehana e hoʻonui i ka mānoanoa papaʻaina daimana. He ≈0.5 inika ke kiʻekiʻe o nā substrate tungsten carbide a loaʻa ke ʻano keʻa a me nā ana like me ka papa daimana. ʻO nā ʻāpana ʻelua, ka papa daimana, a me ka substrate, he mea ʻoki

Hana ʻoki ʻoki PDC.

ʻO ka hoʻokumu ʻana i ka PDC i mau ʻano kūpono no nā mea ʻokiʻoki e pili ana i ka waiho ʻana i ka ʻeke daimana, me kāna pani, i loko o kahi ipu kaomi a laila sintering i ka wela a me ke kaomi.

ʻAʻole hiki ke ʻae ʻia nā mea ʻoki PDC ma mua o ka mahana o 1,382°F [750°C]. ʻO ka wela nui ka mea e hiki ai ke ʻaʻahu wikiwiki no ka mea ʻokoʻa ka hoʻonui ʻana i ka wela ma waena o ka mea hoʻopaʻa a me ke daimana e uhaʻi i nā kristal grit daimana intergrown i ka papa daimana. Hoʻopilikia pū ʻia nā ikaika paʻa ma waena o ka papa daimana a me ka substrate tungsten carbide e ka hoʻonui ʻana i ka wela.

Inā makemake ʻoe i nā huahana tungsten carbide a makemake ʻoe i ka ʻike hou aʻe a me nā kikoʻī, hiki iā ʻoe ke CONTACT US ma ke kelepona a i ʻole leka uila ma ka hema, a i ʻole SEND US MAIL ma lalo o ka ʻaoʻao.
