He mea nui nā ʻāpana kila kila kiʻekiʻe (HSS) i ke ao o ka mīkini kikoʻī. Ua hoʻolālā ʻia kēia mau mea hana ʻoki e kū i nā mahana kiʻekiʻe a mālama i ko lākou paʻakikī, e kūpono ai lākou no nā ʻano hana mīkini like ʻole. Ma kēia ʻatikala, e ʻimi mākou i nā ʻano o nā ʻāpana kila HSS, kā lākou noi, a me nā pono a lākou e hāʻawi ai i nā mīkini a me nā mea hana.
Hana ʻia nā ʻāpana hana HSS mai kahi ʻano kila kūikawā nona nā pae kiʻekiʻe o ke kalapona, tungsten, chromium, vanadium, a me nā mea hoʻohuihui ʻē aʻe. Hāʻawi kēia ʻano hana kūikawā i nā ʻāpana hana HSS i ko lākou paʻakikī kūikawā, ke kūpaʻa i ka ʻaʻahu ʻana, a me ka hiki ke mālama i ko lākou ʻoi ʻoki i nā mahana kiʻekiʻe. ʻO ka hopena, hiki i nā ʻāpana hana HSS ke hana i nā ʻano mea like ʻole, me ke kila, ke kila kila, ka hao i hoʻolei ʻia, a me nā metala hao ʻole.
ʻO kekahi o nā pono nui o nā ʻāpana hana HSS ʻo ia ko lākou hiki ke mālama i ko lākou ʻoi ʻoki i nā wikiwiki kiʻekiʻe a me nā hānai. ʻO kēia ka mea e kūpono ai lākou no nā hana mīkini wikiwiki, kahi e hoʻopilikia ʻia ai ka mea hana ʻoki i ka wela nui a me ka friction. ʻO ke kūpaʻa wela o nā ʻāpana hana HSS e hiki ai iā lākou ke hana i nā wikiwiki ʻoki kiʻekiʻe me ka ʻole o ka hoʻopilikia ʻana i kā lākou hana, e hopena ana i ka hoʻomaikaʻi ʻana i ka huahana a me ka pono i nā kaʻina hana mīkini.
Ma waho aʻe o ko lākou kūpaʻa wela, hōʻike pū nā ʻāpana hana HSS i ke kūpaʻa maikaʻi loa i ka ʻaʻahu ʻana, kahi e hoʻolōʻihi ai i ko lākou ola hana a hoʻemi i ke alapine o ka hoʻololi ʻana i nā mea hana. He mea pono loa kēia i nā wahi hana nui, kahi e koʻikoʻi ai ka hoʻemi ʻana i ka manawa hana a me nā kumukūʻai hoʻololi mea hana. ʻO ke kūpaʻa o nā ʻāpana hana HSS e lilo ai lākou i koho kūpono no nā mea hana e ʻimi nei e hoʻomaikaʻi i kā lākou hana mīkini.
Eia kekahi, ua ʻike ʻia nā ʻāpana hana HSS no ko lākou ʻano hana like ʻole a me ka hiki ke hana i nā ʻano ʻoki like ʻole. Inā paha he huli ʻana, he alo ʻana, he wili ʻana, a he wili ʻana paha, hiki ke wili ʻia nā ʻāpana hana HSS i nā ʻano geometries like ʻole e hoʻokō ai i nā koi mīkini kikoʻī. ʻO kēia ʻano maʻalahi e hiki ai i nā mea hana ke hoʻokō i nā hana mīkini pololei a paʻakikī me ka maʻalahi, e hoʻolilo ana i nā ʻāpana hana HSS i waiwai nui i ka ʻoihana hana.
He ʻokoʻa nā hoʻohana ʻana o nā ʻāpana hana HSS, mai ka mīkini hana maʻamau a hiki i nā hana kūikawā i nā ʻoihana e like me ke kaʻa, ka mokulele, a me ka hana ʻana i nā mea lapaʻau. I ka hana metala, hoʻohana pinepine ʻia nā ʻāpana hana HSS i nā mīkini lathe, nā mīkini wili, a me nā lako wili e hana i nā ʻāpana me nā hoʻomanawanui paʻa a me nā hoʻopau ʻili maikaʻi loa. ʻO ko lākou hiki ke lawelawe i nā ʻano mea like ʻole a me nā kaʻina hana mīkini e lilo ai lākou i mea nui loa i ka hana ʻana i nā ʻāpana a me nā ʻāpana kikoʻī.
I ke koho ʻana i nā ʻāpana hana HSS, loaʻa i nā mīkini nā koho like ʻole e koho ai, me nā ʻano like ʻole, nā uhi, a me nā geometries. ʻO ke koho ʻana o ka ʻāpana hana HSS kūpono e pili ana i nā mea e like me ka mea e mīkini ʻia ana, ka hana ʻoki, a me ka hoʻopau ʻili i makemake ʻia. Hiki i nā mīkini ke hoʻopilikino i nā ʻāpana hana HSS e kūpono i kā lākou mau pono mīkini kikoʻī, inā paha he hana ʻana i nā ʻaoʻao ʻoki maʻamau a i ʻole ka hoʻomaikaʻi ʻana i nā geometries mea hana no ka hana i hoʻonui ʻia.
I ka hopena, he kuleana koʻikoʻi ko nā ʻāpana hana HSS i ka mīkini kikoʻī, e hāʻawi ana i ke kūpaʻa wela kūikawā, ke kūpaʻa ʻana i ka ʻaʻahu, a me ka versatility. ʻO ko lākou hiki ke kū i nā wikiwiki ʻokiʻoki kiʻekiʻe a me nā hānai, me ko lākou kūpaʻa a me ka hiki ke hana i nā ʻano ʻoki like ʻole, e hoʻolilo iā lākou i mea hana ponoʻī no nā mīkini a me nā mea hana. I ka hoʻomau ʻana o ke koi no nā ʻāpana kikoʻī kiʻekiʻe e ulu nei, e mau ana nā ʻāpana hana HSS i kihi o ka ʻoihana mīkini, e hoʻokele ana i ka hana hou a me ka maikaʻi loa i nā kaʻina hana hana.
