ʻEhia mau uhi ʻili no ka HSS drill bit? a ʻo wai ka mea maikaʻi?

ʻO nā ʻāpana wili kila wikiwiki (HSS) pinepine he mau uhi ʻili like ʻole i hoʻolālā ʻia e hoʻomaikaʻi i kā lākou hana a me ke kūpaʻa. ʻO nā uhi ʻili maʻamau no nā ʻāpana wili kila wikiwiki:

1. Uhi ʻokikene ʻeleʻeleHāʻawi kēia uhi i kahi kekelē o ke kūpaʻa ʻana i ka pala a kōkua i ka hōʻemi ʻana i ka friction i ka wā e ʻeli ai. Kōkua pū ia i ka mālama ʻana i ka lubricant ma ka ʻili o ka ʻeli. He kūpono nā ʻāpana ʻeli i uhi ʻia me ka oxide ʻeleʻele no ka ʻeli ʻana i nā mea e like me ka lāʻau, ka plastic a me ka metala.

2. Uhi ʻana o Titanium Nitride (TiN): Hoʻonui ka uhi ʻana o TiN i ke kūpaʻa o ka ʻaʻahu a kōkua i ka hōʻemi ʻana i ka friction, no laila e hoʻolōʻihi ana i ke ola o ka mea hana a hoʻomaikaʻi i ka hana i nā noi wili wela kiʻekiʻe. He kūpono nā ʻāpana wili i uhi ʻia ʻo TiN no ka wili ʻana i nā mea paʻakikī e like me ke kila kila, ka hao i hoʻolei ʻia, a me ka titanium.

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

4. ʻO ka uhi ʻana o ka titanium alumini nitride (TiAlN): ʻO ka uhi ʻana o TiAlN ka pae kiʻekiʻe loa o ke kūpaʻa ʻana i ka ʻaʻahu a me ke kūpaʻa wela ma waena o nā uhi i luna. He kūpono ia no ka ʻeli ʻana i nā kila paʻakikī, nā mea hoʻohuihui wela kiʻekiʻe a me nā mea paʻakikī ʻē aʻe e hoʻolōʻihi i ke ola o ka mea hana a hoʻomaikaʻi i ka hana i nā kūlana ʻeli paʻakikī.

ʻO ka uhi ʻoi aku ka maikaʻi ma muli o ka noi wili kikoʻī a me ka mea e wili ʻia ana. 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, ua lawa paha kahi ʻāpana wili i uhi ʻia me ka oxide ʻeleʻele. Eia nō naʻe, no nā noi koi nui e pili ana i nā mea paʻakikī a i ʻole nā ​​​​mea wela kiʻekiʻe,ʻOi aku ka kūpono o nā ʻāpana wili i uhi ʻia me TiN, TiCN a i ʻole TiAlN ma muli o ko lākou kūpaʻa ʻana i ka ʻaʻahu a me ka wela.
