ʻEhia ka uhi ili no ka bit drill HSS? a ʻo wai ka maikaʻi?

Loaʻa pinepine nā ʻāpana hoʻoheheʻe kila kiʻekiʻe (HSS) i nā ʻili ʻili like ʻole i hoʻolālā ʻia e hoʻomaikaʻi i kā lākou hana a me ka lōʻihi. ʻO nā ʻili ili maʻamau no nā bit drill kila kiʻekiʻe:

1. ʻO ka ʻeleʻele Oxide Coating: Hāʻawi kēia uhi i kahi degere o ka pale ʻana i ka corrosion a kōkua i ka hōʻemi ʻana i ka friction i ka wā wili. He kōkua nō hoʻi i ka mālama ʻana i ka lubricant ma ka ʻili drill. He kūpono nā ʻāpana drill i uhi ʻia ʻeleʻele no ka hana maʻamau i nā mea e like me ka lāʻau, ka plastik a me ka metala.

2. Titanium Nitride (TiN) Coating: Hoʻonui ka uhi ʻana o TiN i ka pale ʻana i ka ʻaʻahu a kōkua i ka hoʻohaʻahaʻa ʻana i ka friction, a laila e hoʻolōʻihi i ke ola mea hana a hoʻomaikaʻi i ka hana ma nā noi wili wela wela. He kūpono nā ʻāpana drill i uhi ʻia ʻo TiN no ka ʻeli ʻana i nā mea paʻakikī e like me ke kila kila, ka hao, a me ka titanium.

3. Titanium carbonitride (TiCN): Hoʻohālikelike ʻia me ka uhi ʻana o TiN, ʻoi aku ka kiʻekiʻe o ka pale ʻana o TiCN a me ka pale wela. He kūpono ia no ka wili ʻana i nā abrasives a me nā mea wela kiʻekiʻe e hoʻomaikaʻi i ke ola mea hana a me ka hana i ke koi ʻana i nā noi wili.

4. Titanium alumini nitride (TiAlN) ka uhi: TiAlN ka uhi i ke kiʻekiʻe kiʻekiʻe o ke kapa komo a me ka wela wela ma waena o luna. He kūpono ia no ka wili ʻana i nā kila paʻakikī, nā ʻāpana wela kiʻekiʻe a me nā mea paʻakikī ʻē aʻe e hoʻolōʻihi i ke ola mea hana a hoʻomaikaʻi i ka hana ma nā kūlana wili paʻakikī.

ʻO ka uhi ʻoi aku ka maikaʻi ma muli o ka noi wili kikoʻī a me nā mea i wili ʻia. Hāʻawi kēlā me kēia uhi i nā pono kūikawā a ua hoʻolālā ʻia no nā ʻano mea like ʻole a me nā kūlana wili. No ka wili ʻana i nā mea maʻamau, lawa paha ka bit drill i uhi ʻia ʻeleʻele. Eia nō naʻe, no nā noi koi nui e pili ana i nā mea paʻakikī a kiʻekiʻe paha,ʻOi aku ka maikaʻi o nā pahu drill i uhi ʻia ʻo TiN, TiCN a i ʻole TiAlN ma muli o ko lākou ʻaʻahu maikaʻi a me ke kūpaʻa wela.
