Pehea e hana ai i nā mea ʻoki PDC

Ua hoʻokumu mua ʻia ʻo PDC Cutter e General Electric (GE) i ka makahiki 1971. Ua hoʻokomo ʻia ma ke kālepa ma 1976 ma hope o ka hōʻoia ʻana i ʻoi aku ka maikaʻi ma mua o ka hana ʻoki ʻana i nā pihi pihi carbide. Noho ʻia nā bits PDC ma mua o 90% o ka nui o nā kiʻi wili i ka honua. Akā, ʻike ʻoe pehea i hana ʻia ai nā mea ʻoki PDC? Makemake au e kaʻana like me ʻoe ma aneʻi.

Mea lako

E koho i ke daimana premium, e ʻoki a hana hou ia, e hoʻonui i ka nui o ka ʻāpana, e hoʻomaʻemaʻe i ka mea daimana. No ka tungsten carbide substrate, hoʻohana mākou i ka pauka puʻupaʻa kiʻekiʻe a me ka pae carbide kūpono me ka hopena kiʻekiʻe.

HTHP sintering

1. mea hoʻohana ʻoihana a me nā ʻoihana kiʻekiʻe e hana i nā mea ʻoki PDC

2. E nānā i ka mahana a me ke kaomi i ka manawa maoli a hoʻololi i ka manawa. ʻO 1300 - 1500 ka mahana℃. ʻO ke kaomi ʻana he 6 - 7 GPA.

3. Pono ka hana ʻana i hoʻokahi ʻāpana PDC Cutters ma kahi o 30 mau minuke.

Nānā ʻāpana mua

Ma mua o ka hana nui ʻana, e nānā i ka ʻāpana mua e ʻike inā kūpono ia i nā koi o ka mea kūʻai aku no ka nui a me ka hana.

Ka wili ʻana

1. ana wili ana: wili i ke anawaena o waho a me ke kiekie. e hoʻohana i ka mea wili cylindrical e hana i ka wili waho i ka billet huahana. No ka mea ua loli paha ka mea i ka wā o ke kaomi kiʻekiʻe a me ka synthesis kiʻekiʻe, ʻaʻole i kūpono ke ʻano o ka huahana i loaʻa a hoʻokō i ke koi o ka helehelena huahana, a pono e loaʻa kahi cylinder kūpono ma o ka wili ʻana i waho.

2. chamfer wili: pono ka chamfer ma kahi o 0.1-0.5mm me ka huina o 45; kaHiki ke hoʻopaʻa ʻia ka chamfer i nā degere like ʻole e like me ka makemake o ka mea kūʻai.

Nānā i nā huahana i hoʻopau ʻia

No ka hōʻoia ʻana ua kūpono a kūlike nā mea ʻoki PDC āpau, pono mākou e nānā i nā mea ʻoki PDC hope loa. Pono e nānā ʻia ka nānā ʻana i nā mea e like me ke ʻano, ka nui, a me ka hana kino, a laila e hoʻokaʻawale a hoʻopaʻa i nā huahana ma hope o ka nānā ʻia ʻana i kūpono. He hana koʻikoʻi kēia e hōʻoiaʻiʻo ai i ka maikaʻi o ka huahana; ʻO ke ana ʻana o ka mānoanoa o ke daimana polycrystalline pono e hoʻoikaika ʻia i ka wā o ka nānā ʻana o ka huahana.

Hoʻopili

ʻO ka hiʻohiʻona a me nā ana o ka huahana i waho e kūpono i ka maʻamau ʻoihana, ʻoi aku, ʻaʻole pono e loli ke ʻano o ka huahana a me nā ana i ka wā o ka halihali lōʻihi. ʻO ka mua i loko o kahi pahu ʻilika, a laila i loko o kahi pahu pahu.

Ma ZZbetter, hiki iā mākou ke hāʻawi i kahi ākea o nā mea ʻoki kikoʻī.
