Nā ʻano like ʻole o nā ʻāpana wili

ʻO ka wili ʻana kekahi o nā kumu koʻikoʻi no ka hana maikaʻi ʻana o ka wili. No laila, he mea koʻikoʻi loa ke koho ʻana i nā pahu drill kūpono. ʻO ka wili no ka ʻaila ʻaila a me ke kinoea e loaʻa nā ʻāpana ʻoki ʻoki a me nā ʻoki ʻoki paʻa.

ʻOki ʻoki ʻāwili

Kapa ʻia nā ʻāpana ʻoki ʻoki ʻoki ʻia he ʻāpana cone wili a i ʻole ʻāpana tri-cone. ʻEkolu cones nā ʻāpana ʻoki ʻoki. Hiki ke hoʻololi i kēlā me kēia cone i ka wā e hoʻohuli ai ke kaula drill i ke kino o ka bit. Loaʻa i nā cones nā huila huila i hoʻokomo ʻia i ka manawa o ka hui ʻana. Hiki ke hoʻohana ʻia nā ʻoki ʻoki ʻōwili e wili i nā ʻano ʻano inā koho ʻia ka mea ʻoki kūpono, bea, a me ka nozzle.

ʻElua ʻano ʻāpana ʻoki ʻoki ʻia ʻo ia nā ʻāpana niho wili a me nā mea hoʻokomo tungsten carbide (TCI bits). Hoʻokaʻawale ʻia kēia mau ʻāpana e ke ʻano o ka hana ʻana o nā niho:

Nā ʻāpana niho wili

He mau mea ʻoki niho kila, i hana ʻia e like me nā ʻāpana o ka bit cone. Ua ʻoki ʻia nā ʻāpana a i ʻole ka hoʻopuʻi ʻana i waho i ka wā e kahuli ʻia ai. ʻOkoʻa ka nui a me ke ʻano o nā niho, ma muli o ka hoʻokumu ʻana. ʻOkoʻa nā niho o nā ʻāpana ma muli o ka hoʻokumu ʻana penei:

Hoʻokumu palupalu: Pono nā niho e lōʻihi, lohi, a ākea ākea. Na kēia mau niho e hana i nā ʻokiʻoki hou mai nā ʻano palupalu.

ʻO Tungsten Carbide Insert (TCI) a i ʻole Insert bits maʻamau loaʻa nā tungsten carbide inserts (niho) i kaomi ʻia i loko o nā cones bit. Loaʻa i nā mea hoʻokomo nā ʻano like ʻole e like me nā ʻano hoʻonui lōʻihi, nā mea hoʻokomo ʻano poepoe, etc.

ʻOkoʻa nā niho o nā ʻāpana ma muli o ke kūkulu ʻana penei:

Hoʻokumu palupalu: Hoʻokomo lōʻihi, hoʻokomo ʻano chisel

Hoʻokumu paʻakikī: Hoʻonui pōkole, hoʻokomo poʻe

ʻOki ʻoki paʻa

Aia nā ʻāpana ʻoki paʻa i nā kino bit a me nā mea ʻoki i hoʻohui ʻia me nā kino bit. Hoʻolālā ʻia nā ʻoki ʻoki paʻa no ka ʻeli ʻana i nā lua ma o ka ʻoki ʻana i nā ʻāpana ma mua o ka ʻoki ʻana a i ʻole ka ʻoki ʻana i nā ʻano, e like me nā ʻāpana ʻoki ʻoki. ʻAʻohe o kēia mau ʻāpana e like me nā cones a me nā bearings. Hoʻokumu ʻia nā ʻāpana o nā bits i nā kino bit i hana ʻia mai ke kila a i ʻole ka tungsten carbide matrix a me nā ʻāpana paʻa i hoʻohui ʻia me nā mea ʻoki abrasion-resistant. ʻO nā mea ʻoki i loko o nā ʻāpana i loaʻa ma ka mākeke ʻo Polycrystalline Diamond Cutters (PDC) a me nā mea ʻoki daimana kūlohelohe a i ʻole synthetic.

I kēia mau lā, me ka hoʻomaikaʻi ʻana i hana ʻia i ka ʻenehana ʻokiʻoki paʻa, hiki i nā bits PDC ke hoʻoheheʻe i nā ʻano ʻano like ʻole mai ka papa palupalu a paʻakikī.

Hana ʻia nā ʻāpana drill polycrystalline diamond compact (PDC) me nā mea ʻoki daimana synthetic i loko o ke kila a i ʻole nā ​​mea kino matrix. Ua hoʻololi ʻo PDC drill bits i ka ʻoihana wili me ka laulā noi ākea a me ka hiki ke kiʻekiʻe o ke komo ʻana (ROP).

Inā makemake ʻoe i ka mea ʻoki PDC a makemake ʻoe i ka ʻike hou aʻe a me nā kikoʻī, hiki iā ʻoe ke CONTACT US ma ke kelepona a i ʻole ka leka uila ma ka hema, a i ʻole SEND US MAIL ma lalo o ka ʻaoʻao.
