DW1214 wili daimana i hoʻonui ʻia
I kēia manawa hiki i ka hui ke hana i nā pepa huikau non-planar o nā ʻano like ʻole a me nā kikoʻī e like me ke ʻano wedge, triangular cone type (pyramid type), truncated cone type, three-edged Mercedes-Benz type, a me flat arc type structure. I ka wā o ka wili ʻana o ka bit daimana, ua hoʻololi ka niho i hoʻohui ʻia i ke daimana i ke ʻano hana o ka pepa daimana planar composite mai ka "scraping" a i ka "plowing". ʻO ka ʻoki ʻana i nā niho i mua o ke kūʻē ʻana, a hoʻemi i ka haʻalulu ʻoki ʻana o ka bit drill.

CB1319 Dome- Conical DEC (kopa i hoʻonui ʻia ke daimana)
Hoʻokumu ka hui i nā ʻāpana composite non-planar me nā ʻano like ʻole a me nā kikoʻī e like me ke ʻano wedge, triangular cone type (pyramid type), truncated cone type, triangular Mercedes-Benz type, flat arc structure, etc. Ua hoʻohana nui ʻia i ka ʻeli ʻana a me nā māla e like me nā bits daimana, nā ʻāpana cone roller, nā mining bits, a me nā mīkini ʻoki. I ka manawa like, kūpono loa ia no nā ʻāpana hana kikoʻī o nā pahu drill PDC, e like me nā niho nui / kōkua, nā niho ana nui, a me nā niho lālani lua.

DW1318 Wedge PDC Hookomo
ʻOi aku ka maikaʻi o ka hopena o ka Wedge PDC Insert ma mua o ka Plane PDC, ʻoi aku ka ʻoi aʻe a me ke kūpaʻa hopena maikaʻi ma mua o ka Conical PDC Insert. Ma ke kaʻina hana o ka PDC bit drilling, hoʻomaikaʻi ka Wedge PDC Insert i ka "scraping" hana hana o ka mokulele PDC i ka "ploughing". He mea kūpono kēia hale i ka ʻai ʻana i loko o ka pōhaku paʻakikī, e hāpai ana i ka hoʻokuʻu wikiwiki ʻana o nā ʻōpala pōhaku, e hōʻemi ana i ke kūpaʻa mua o ka PDC Insert, e hoʻomaikaʻi i ka maikaʻi o ka wāwahi pōhaku me ka lesstorque. Hoʻohana nui ʻia ia no ka hana ʻana i ka aila a me ka mining bits.

DB1315 Diamond Dome DEC Niho
Hana nui ka hui i ʻelua ʻano huahana: polycrystalline diamond composite sheet a me daimana composite tooth.
Hoʻohana nui ʻia nā niho hoʻohui daimana (DEC) i ka ʻeli ʻenehana a me nā kahua kūkulu e like me ka roller cone bits, down-the-hole bits, engineering drilling tools, a me nā mīkini ʻoki. Ma ka manawa like, hoʻohana ʻia ka nui o nā ʻāpana hana kikoʻī o nā ʻāpana drill PDC, e like me nā niho hoʻohāhā, nā niho waena, a me nā niho gauge. Loaʻa ka pōmaikaʻi mai ka ulu mau ʻana o ka hoʻomohala ʻana o ka shale gas a me ka hoʻololi lohi ʻana i nā niho carbide cemented, ke hoʻomau nei ka ulu ʻana o ka noi no nā huahana DEC.
