He aha nā mea i hoʻohana pinepine ʻia no nā mīkini hana?

He kuleana koʻikoʻi ko nā mea hana lako i ke ola o kēlā me kēia lā a me ka hana ʻoihana. Hoʻopilikia pololei ke koho ʻana i kā lākou mau mea i ka hana a me ke ola lawelawe o nā mea hana. Eia kekahi mau mea i hoʻohana pinepine ʻia no nā mea hana lako a me ko lākou mau ʻano:

ʻO ka mea mua, ke kila kila kalapona
ʻO ke kila kila kalapona kekahi o nā mea nui no ka hana ʻana i nā mea hana, me ka paʻakikī kiʻekiʻe a me ke kūpaʻa i ka ʻaʻahu. Hoʻohana pinepine ʻia ia e hana i nā mea hana e like me nā hāmare lima, nā kī a me nā wiliwili. ʻO ka nui o ke kalapona o ke kila kila kalapona ma waena o 0.65% a me 1.35%. Ma hope o ka mālama ʻana i ka wela, hiki i kona paʻakikī ke hiki i ka HRC60-65. Hiki i nā mea hana i hana ʻia me kēia mea ke mālama i ka ʻoi maikaʻi o ka lihi i ka wā e hoʻohana ai a kūpono no ka hana maikaʻi ʻana.

ʻO ka lua, ke kila kila
Hoʻomohala ʻia ke kila kila ma ke kumu o ke kalapona mea hana kila ma ka hoʻohui ʻana i nā mea hao hao (e like me chromium, manganese, tungsten, vanadium, a pēlā aku) e hoʻonui i ka hana o nā mea hana. ʻOi aku ka paʻakikī o ke kila kila hao, ke kūpaʻa a me ka paʻakikī, a kūpono no ka hana ʻana i nā mea hana e pono ai ke kū i ka hopena nui a me ka ʻaʻahu, e like me nā chisels, nā punches a me nā mea ʻoki wili. Hiki i ka paʻakikī o ke kila kila hao ke hiki i ka HRC60-70, hiki ke hoʻokō i nā koi o ka hana kiʻekiʻe.

ʻO ke kolu, kila kila wikiwiki
ʻO ke kila kila wikiwiki kahi ʻano kila kila hana kiʻekiʻe, nona nā mea hoʻohuihui e like me ka tungsten, molybdenum, chromium a me vanadium. Hiki i nā mea hana i hana ʻia me kēia mea ke mālama i ka hana ʻoki maikaʻi loa ma lalo o nā kūlana ʻoki wikiwiki, e hōʻike ana i ka paʻakikī kiʻekiʻe, ke kūpaʻa kiʻekiʻe o ka ʻaʻahu a me ke kūpaʻa wela kiʻekiʻe. Hiki i ka paʻakikī o ke kila kila wikiwiki ke hiki i ka HRC63-70, e kūpono ai no ka hana ʻana i nā mea hana ʻoki e like me nā mea hana huli, nā mea ʻoki wili, a me nā wili. I ka wā o ke kaʻina hana ʻoki wikiwiki, hiki i ke kila kila wikiwiki ke mālama i ka ʻoi o ka ʻoi o ka ʻoki, hoʻemi i ka ʻaʻahu o ka mea hana a hoʻomaikaʻi i ka pono o ka hana ʻana.

ʻEhā, carbide sima
ʻO ke kinikini paʻakikī kahi mea kinikini i hana ʻia e ke kaʻina hana metallurgy pauka mai nā hui paʻakikī o nā metala refractory a me nā metala hoʻopaʻa. He paʻakikī kiʻekiʻe loa kona a me ke kūpaʻa ʻana i ka ʻaʻahu, me ka paʻakikī e hiki ana i ka HRA89-93, ʻoi aku ka kiʻekiʻe ma mua o ke kila mea hana maʻamau. Hoʻohana pinepine ʻia ke kinikini paʻakikī e hana i nā mea ʻoki e like me nā ʻāpana wili, nā mea ʻoki wili a me nā mea hana wili, a kūpono loa ia no ka hana ʻana i nā mea me ka paʻakikī kiʻekiʻe, e like me ke kila kila a me ka hao i hoʻolei ʻia. Ma muli o kona paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana i ka ʻaʻahu, ʻoi aku ka lōʻihi o ke ola lawelawe o nā mea hana kinikini paʻakikī a hiki ke hoʻomaikaʻi nui i ka pono hana.

ʻElima, kila kila
He kila kila kila me ke kūpaʻa maikaʻi loa i ka pala, aia ma ka liʻiliʻi he 10.5% chromium. He kūpaʻa maikaʻi ko nā mea hana kila kila i ka pala i nā wahi pulu a kūpono no nā wahi pulu e like me nā lumi kuke a me nā lumi ʻauʻau. ʻO ka paʻakikī o ke kila kila ma waena o HRC20 a me 30. ʻOiai ʻaʻole kiʻekiʻe kona paʻakikī e like me ke kila kila kalapona a me ke kila kila kila, ʻo kona kūpaʻa i ka pala a me ka paʻakikī e lilo ia i mea kūpono no ka hana ʻana i nā mea hana e like me nā wrenches, screwdrivers a me nā pliers. Nā mea hana kila kila ʻaʻole wale ka nani o ke ʻano akā he ola lawelawe lōʻihi a me nā kumukūʻai mālama haʻahaʻa.

ʻO ke ono, ka hui alumini
He mea metala māmā a ikaika hoʻi ka alumini me ka conductivity uila a me ka thermal maikaʻi loa. Hoʻohana pinepine ʻia nā mea hana alumini e hana i nā kukui uila, nā pahu mea hana, nā kī, a pēlā aku. He haʻahaʻa iki ka nui o ka alumini, hoʻokahi hapakolu wale nō o ke kila. No laila, he māmā ke kaumaha o nā mea hana alumini, maʻalahi ke lawe a hoʻohana. I kēia manawa, he kūpaʻa maikaʻi loa ka alumini i ka pala a kūpono no ka hoʻohana ʻana i nā wahi pulu. ʻO ka paʻakikī o nā mea hana alumini ma waena o HB60 a me 100. ʻOiai he haʻahaʻa iki ka paʻakikī, ʻo kona paʻakikī a me ka māmā e hāʻawi iā ia i nā pono kūikawā i kekahi mau hiʻohiʻona noi.

ʻEhiku, Palakiko
He mea māmā a hoʻokaʻawale ka palakiko me ke kūpaʻa maikaʻi loa i ka pala a me ka hoʻokaʻawale ʻana. Hoʻohana pinepine ʻia nā mea hana palakiko e hana i nā lima, nā mea hana hoʻokaʻawale, a pēlā aku. He haʻahaʻa ka nui o ka palakiko, he māmā, a maʻalahi hoʻi e lawe a lawelawe. I kēia manawa, he maikaʻi nā waiwai hoʻokaʻawale o ka palakiko a kūpono no ka mālama uila a me ka mālama ʻana i nā lako uila. ʻO ka paʻakikī o nā mea hana palakiko ma waena o HB20 a me 40. ʻOiai he haʻahaʻa ko lākou paʻakikī, hāʻawi ko lākou hoʻokaʻawale a me ka māmā iā lākou i nā pono kūikawā i kekahi mau hiʻohiʻona noi.

ʻEwalu, nā mea hoʻohui keleawe
He ʻano mea metala ka mea hoʻohuihui keleawe me ka conductivity uila a me ka thermal maikaʻi loa, a hoʻohana pinepine ʻia e hana i nā mea hana uila, nā hāmare keleawe, a pēlā aku. ʻO ka paʻakikī o nā mea hoʻohuihui keleawe ma waena o HB80 a me 120. ʻOiai he haʻahaʻa kona paʻakikī, ʻo kona conductivity uila maikaʻi loa a me ka paʻakikī e lilo ia i mea kūpono no ka hana ʻana i nā mea hana uila. Hoʻohana nui ʻia nā mea hana mea hoʻohuihui keleawe i ka mālama uila a me ka mālama ʻana i nā lako uila, e pale pono ana i ka hōʻino ʻana i nā lako i hana ʻia e nā mea hana.

ʻEiwa, Hōʻuluʻulu Manaʻo
Ke koho ʻana i nā mea o ka mīkini nā mea hana He hopena koʻikoʻi ko lākou i kā lākou hana a me ke ola lawelawe. He kūpono ke kila kila kalapona a me ke kila kila alloy no ka hana ʻana i nā mea hana e pono ai ka paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana i ka ʻaʻahu. He kūpono ke kila kila wikiwiki a me ke carbide cemented no ka hana ʻana i nā mea hana ʻoki kiʻekiʻe. ʻO ke kila kila kila a me ke alumini alloy, ma muli o ko lākou kūpaʻa maikaʻi loa i ka pala a me ka māmā, kūpono no nā wahi haumī a me nā hiʻohiʻona e pono ai nā mea hana lawe lima. He kūpono nā plastics a me nā mea hoʻohui keleawe no ka hana ʻana i nā mea hana kikoʻī ma muli o ko lākou mau waiwai insulating a me conductive. I ke koho ʻana i nā mea hana lako, pono e koho ʻia ka mea kūpono e pili ana i nā koi hoʻohana kikoʻī a me nā kūlana kaiapuni e hōʻoia i ka hana a me ke ola lawelawe o nā mea hana.

Manaʻolana ʻia e hiki i ka ʻike ma luna nei ke kōkua iā ʻoe e hoʻomaopopo maikaʻi i nā mea maʻamau a me nā ʻano o nā mea hana lako. Inā he mau nīnau kāu e pili ana i nā mea o nā mea hana lako a i ʻole makemake i ka ʻike hou aku, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou i kēlā me kēia manawa.
