ʻO ka DW1214 daimana wedge i hoʻonui ʻia i ka compact
I kēia manawa, hiki i ka ʻoihana ke hana i nā pepa hui ʻole planar o nā ʻano like ʻole a me nā kikoʻī e like me ke ʻano wedge, ke ʻano triangular cone (ʻano pyramid), ke ʻano truncated cone, ke ʻano ʻekolu ʻoi o Mercedes-Benz, a me ke ʻano arc pālahalaha. ʻOi aku ka ikaika o nā niho hui daimana ʻano wedge i ke kūpaʻa i ka hopena a me ka paʻakikī ma mua o nā niho hui pālahalaha, a he ʻoi aku ka ʻoi o nā lihi ʻoki a me ke kūpaʻa i ka hopena ʻaoʻao i hoʻohālikelike ʻia me nā niho hui tapered. I ka wā o ke kaʻina hana wili o ka ʻāpana daimana, hoʻololi ka niho hui daimana ʻano wedge i ke ʻano hana o ka pepa hui daimana planar mai ka "scraping" a i ka "plowing". Hoʻonui ka ʻoki ʻana i nā niho i ke kūpaʻa, a hoʻemi i ka haʻalulu ʻoki o ka ʻāpana wili.

CB1319 Dome- Conical DEC (paʻa i hoʻonui ʻia e ka daimana)
Hana ka ʻoihana i nā pepa composite non-planar me nā ʻano like ʻole a me nā kikoʻī e like me ke ʻano wedge, ke ʻano triangular cone (ʻano pyramid), ke ʻano truncated cone, ke ʻano triangular Mercedes-Benz, ke ʻano flat arc, a pēlā aku. Hoʻohana ʻia ka ʻenehana kumu o ka pepa composite daimana polycrystalline, a ua paʻi ʻia a hana ʻia ke ʻano o ka ʻili, nona ka ʻoi ʻoi aku ka ʻoi a me ka hoʻokele waiwai maikaʻi. Ua hoʻohana nui ʻia ia i nā kahua wili a me ka mining e like me nā ʻāpana daimana, nā ʻāpana roller cone, nā ʻāpana mining, a me nā mīkini wili. I ka manawa like, kūpono loa ia no nā ʻāpana hana kikoʻī o nā ʻāpana wili PDC, e like me nā niho nui/kōkua, nā niho ana nui, a me nā niho lālani ʻelua.

Hoʻokomo PDC Wedge DW1318
ʻOi aku ka maikaʻi o ke kūpaʻa ʻana o ka Wedge PDC Insert ma mua o ka Plane PDC, ʻoi aku ka ʻoi o ka lihi a ʻoi aku ka maikaʻi o ke kūpaʻa ʻana ma mua o ka Conical PDC Insert. I ke kaʻina hana o ka ʻeli ʻana o ka PDC bit, hoʻomaikaʻi ka Wedge PDC Insert i ka ʻano hana "scraping" o ka plane PDC i ka "ploughing". He kūpono kēia ʻano hana no ka ʻai ʻana i ka pōhaku paʻakikī, e paipai ana i ka hoʻokuʻu wikiwiki ʻana o nā ʻōpala pōhaku, e hōʻemi ana i ke kūpaʻa i mua o ka PDC Insert, e hoʻomaikaʻi ana i ka pono o ka haki ʻana o ka pōhaku me ka lesstorque. Hoʻohana nui ʻia ia no ka hana ʻana i ka ʻaila a me nā ʻāpana eli.

Nā Niho DEC Diamond Dome DB1315
Hoʻopuka nui ka ʻoihana i ʻelua ʻano huahana: ka pepa composite daimana polycrystalline a me ka niho composite daimana.
Hoʻohana nui ʻia nā niho hui daimana (DEC) i nā kahua ʻeli ʻenekinia a me ke kūkulu ʻana e like me nā ʻāpana cone roller, nā ʻāpana down-the-hole, nā mea hana ʻeli ʻenekinia, a me nā mīkini wili. I ka manawa like, hoʻohana ʻia ka nui o nā ʻāpana hana kikoʻī o nā ʻāpana wili PDC, e like me nā niho hoʻopūhoihoi, nā niho waena, a me nā niho ana. Ma muli o ka ulu mau ʻana o ka hoʻomohala ʻana o ke kinoea shale a me ka hoʻololi mālie ʻana o nā niho carbide cemented, ke ulu ikaika nei ke koi no nā huahana DEC.
