Pehea e koho ai i nā mea ʻoki PDC kūpono?

ʻO ka PDC drill Bits Design o kēia lā ma ke ʻano he matrix ʻaʻole like me kēlā o nā makahiki i hala. Ua hoʻonui ʻia ka ikaika tensile a me ke kūʻē ʻana i ka hopena ma ka liʻiliʻi he 33%, a ua hoʻonui ʻia ka ikaika o nā brazes cutter e ≈80%. I ka manawa like, ua hoʻomaikaʻi ʻia nā geometries a me ka ʻenehana o ke kākoʻo ʻana i nā hale, ka hopena i nā huahana matrix ikaika a huahua.
Mea ʻokiʻoki
Hana ʻia nā ʻokiʻoki PDC mai ka substrate carbide a me ka grit daimana. ʻO ka wela kiʻekiʻe ma kahi o 2800 degere a me ke kaomi kiʻekiʻe ma kahi o 1,000,000 psi e hana i ka compact. Hoʻohana pū kekahi ʻāpana cobalt ma ke ʻano he catalyst no ke kaʻina sintering. Kōkua ka cobalt e hoʻopaʻa i ka carbide a me ke daimana.
Ka helu o na mea oki
Hoʻohana maʻamau mākou i nā mea ʻoki liʻiliʻi ma nā ʻāpana PDC palupalu e like me ka wehe ʻana o kēlā me kēia ʻoki i kahi hohonu o ka ʻoki. No nā hana ʻoi aku ka paʻakikī, pono e hoʻohana i nā mea ʻokiʻoki hou aʻe e uku i ka hohonu liʻiliʻi o ka ʻoki.

PDC Drill Bits – Ka nui o nā mea ʻoki
No nā hana palupalu, koho maʻamau mākou i nā ʻokiʻoki nui aʻe ma mua o nā ʻano paʻakikī. ʻO ka maʻamau, ʻo ka laulā maʻamau o ka nui mai 8 mm a i 19 mm ma luna o kekahi.

Hōʻike maʻamau mākou i ka hoʻolālā hoʻolālā ʻoki ʻoki ma nā kihi rake hope a me nā kihi rake ʻaoʻao.
● ʻO ka ʻoki hope rake ka huina i hōʻike ʻia e ka maka o ka mea ʻoki i ka hoʻokumu ʻana a ua ana ʻia mai ke kū pololei. ʻOkoʻa nā kihi rake hope ma waena, maʻamau, 15° a 45°. ʻAʻole paʻa lākou i kēlā me kēia bit, ʻaʻole hoʻi mai kahi iki a i kahi iki. ʻO ka nui o ke kihi ʻoki ʻoki no nā ʻāpana drill PDC e pili ana i ka Penetration Rate (ROP) a me ke kūʻē ʻana o ka ʻokiʻoki i ka lole. I ka piʻi ʻana o ke kihi rake, hoʻemi ʻia ka ROP, akā piʻi ke kūʻē ʻana i ka ʻaʻahu ʻoiai ua hoʻolaha ʻia ka ukana i hoʻopili ʻia ma kahi ʻāpana ʻoi aku ka nui. ʻO nā mea ʻoki PDC me nā ʻoki liʻiliʻi liʻiliʻi e lawe i ka hohonu o ka ʻoki ʻana a no laila ua ʻoi aku ka huhū, e hoʻoulu i ka Torque kiʻekiʻe, a hiki ke hoʻopaʻa ʻia i ka ʻaʻahu a me ka nui o ka pōʻino.

●ʻO ka ʻaoʻao ʻoki ʻoki he ana like ia o ka hoʻonohonoho ʻana o ka mea ʻoki mai ka hema a i ka ʻākau. He liʻiliʻi nā kihi rake ʻaoʻao. Kōkua ka ʻaoʻao rake angle i ka hoʻomaʻemaʻe ʻana i ka lua ma ke kuhikuhi ʻana i nā ʻokiʻoki i ka annulus.
