He aha ka ʻokoʻa ma waena o ka bit PDC kino kila a me ka bit PDC kino Matrix?

Ua hoʻokaʻawale ʻia nā ʻāpana wili PDC i ʻelua ʻano ma muli o kā lākou mea kumu: Kino Matrix a me ke kino kila, akā ʻokoʻa loa kā lākou hana hana. ʻAʻole i kaupalena ʻia nā ʻāpana PDC kino kila e ka ikaika o nā ʻaoʻao ʻoki, he ikaika lei aliʻi kiʻekiʻe, ikaika brazing kiʻekiʻe o nā papa composite, maʻalahi e hoʻoponopono ma hope o ka hoʻohana ʻana, he kaʻina hana pōkole, ʻoi aku ka maikaʻi o ka hana ʻana, a me nā kumukūʻai hana haʻahaʻa, e hāʻawi ana i nā pono hou aʻe ma mua o nā ʻāpana PDC kino Matrix. Hana ʻia nā ʻāpana PDC kino Matrix e ka impregnation pressureless a me ka sintering o ka pauka tungsten carbide i hoʻolei ʻia a me ka mea impregnating. Hoʻokō pololei ʻia ke ʻano o ke kino wili ma o ke ʻano o ka mold. Aia ka mold i ʻekolu ʻāpana: kahi mold lalo, kahi mold waena, a me kahi mold luna. He maʻalahi ka hoʻolālā a me ka mīkini ʻana o nā mold waena a me luna. Eia naʻe, he paʻa ka mold lalo me nā hiʻohiʻona ʻili piʻo paʻakikī. Hoʻokō ʻia nā ʻāpana ʻano lei aliʻi, ke kūlana niho ʻoki a me nā ʻāpana kuhikuhi, a me nā ʻāpana hoʻonohonoho hydraulic o ka PDC drill bit ma o ke ʻano o ka mold lalo. No laila, ʻo ka hoʻolālā a me ka mīkini ʻana o ka mold lalo ka ʻāpana koʻikoʻi o ka hoʻolālā a me ka mīkini ʻana i ka mold; ʻO kona ʻano hoʻolālā a me ka pololei o ka mīkini e pili pono ana i ka hana hope loa o ka drill bit. ʻO nā ʻōmole kiʻekiʻe kekahi o nā kumu nui i ka hōʻoia ʻana i ka maikaʻi o nā PDC drill bits.

Ma muli o ka manaʻo o nā mea kūʻai aku i kēia manawa, ʻo nā ʻāpana PDC kino kila ke ʻano nui i ka mākeke ʻāpana PDC. Ma muli o ka hoʻomohala ʻana o ka ʻoihana hou, hōʻike nā ʻāpana PDC kino kila i ka hana e like me nā ʻāpana PDC kino matrix. Eia kekahi, no ka mea, ʻo nā ʻāpana PDC kino matrix ke kumu o ka haumia o ka ea, ʻo nā ʻāpana PDC kino kila ke aliʻi nei i ka mākeke i kēia manawa.
