Kaʻina hana o ka wili wili

Wahi a nā ʻano hana hoʻoili like ʻole, ua māhele ʻia nā twist drills i kēia manawa ma ka mākeke i kēia mau ʻano:

1. wiliwili ʻōwili ʻia

Ma hope o ka hoʻomehana ʻia ʻana o ke kila kiʻekiʻe a puhi ʻia i ka ʻulaʻula, ua ʻōwili koke ʻia ke ʻano o ka drill twist i ka manawa hoʻokahi.Ma hope iho, kawiliwili wiliwili pono e hoʻomaʻamaʻa wela a hoʻomaʻamaʻa ʻia i luna e hoʻokala i ke poʻo ma mua o ka hoʻohana ʻana.

ʻO ka pōmaikaʻi nui loa o ke kaʻina hana ka hana kiʻekiʻe a me ka hoʻohana piha ʻana i nā mea maka;ʻO ke ʻano o loko o ke kino drill i hana ʻia he mau ka fiber, a hoʻomaʻemaʻe ʻia nā kīʻaha, hoʻohele like ʻia nā carbide, a kiʻekiʻe ka ʻulaʻula.

Eia nō naʻe, ʻo ke kaʻina o ka ʻōwili ʻana he mau hemahema maopopo, ʻo ia hoʻi, he maʻalahi loa ke kino drill e haki, a i ʻole e loaʻa kekahi mau māwae ʻaʻole maʻalahi ke ʻike, a no ka mea i hana ʻia i ka manawa hoʻokahi, ʻo ka pololei holoʻokoʻa o ka drill. ʻaʻole e kiʻekiʻe loa.

I kēia manawa, wilihoʻomaʻamaʻa mauHoʻohana maʻamau i kēia ʻano kaʻina hana, no laila ʻo ka ʻōwili wili ʻana i ka mākeke kālepa haole he ʻano haʻahaʻa a haʻahaʻa.

2. Ke wili i hopewiliwili wiliwili

Ma muli o ke ʻano o ka maʻalahi o ka ʻōwili ʻana i nā māwae, ʻoi aku ma mua o 98% o nā māwae o nā ʻōwili wiliwili i hana ʻia ma ka hui ʻana o ka ʻāina a me ke awāwa.

Eia nō naʻe, ʻo ka ʻōwili mua ʻana i ka ʻaoʻao o ka pahu ma luna o ka wili wili, a laila e wili maikaʻi i ka pōʻai o waho ma ka mea hana mīkini, e hoʻonā pono i kēia pilikia.

A ma ke kaʻina hana o ka wili maikaʻi ʻana i ka pōʻai o waho, ʻaʻole hiki ke hoʻoponopono wale ʻia ka pilikia o nā māwae, akā hiki ke hoʻomaikaʻi ʻia ka pololei o ka mīkini ʻana o ka drill bit a me ka pololei o ka radial circular runout.

I kēia manawa, ʻo ka ʻenehana wili wili ʻoi loa ma ka honua, nā wili wili i hana ʻia me nā huila wili mai ka ʻoki ʻana i nā mea, a hiki i ka wili ʻana, ka wili hope, ka ʻoki kihi a me ka ʻoki kihi.

He nani a maʻemaʻe ka hiʻohiʻona o ka drill twist piha a me ka poni, a ua hoʻomalu maikaʻi ʻia nā ʻāpana kī e like me ka radial runout, ka mānoanoa kumu, a me ka hoʻonui ʻana i ka mānoanoa kumu, a ʻoi aku ka kiʻekiʻe o ka pololei.

Eia nō naʻe, ʻo ka ʻoiaʻiʻo, ʻoiai ka lōʻihi o ke kaʻina o ka ʻōwili a me ka pae mālama wela, ʻoi aku ka maikaʻi o ka ʻōwili ʻana mai ke ʻano o ka lōʻihi.
