Pehea e koho ai i kahi drill?

I kēia lā, e kaʻana like wau pehea e koho ai i kahi drill bit ma o ʻekolu mau kūlana kumu o kaʻūmiʻi wili, ʻo ia hoʻi: nā mea, ka uhi ʻana a me nā ʻano geometric.

Pehea e koho ai i ka mea o ka drill

Hiki ke hoʻokaʻawale ʻia nā mea i ʻekolu ʻano: kila wikiwiki, kila wikiwiki me ka cobalt a me ka carbide paʻa.

Kila wikiwiki kiʻekiʻe (HSS):

ʻO ke kila wikiwiki ka mea hana ʻokiʻoki i hoʻohana nui ʻia a makepono loa i kēia manawa. ʻAʻole hiki ke hoʻohana ʻia ka ʻāpana wili kila wikiwiki ma nā wili uila lima wale nō, akā ma nā wahi me ke kūpaʻa maikaʻi e like me nā mīkini wili. ʻO kekahi kumu no ke ola lōʻihi o ke kila wikiwiki, ʻo ia paha ka hiki ke wili pinepine ʻia ka mea hana i hana ʻia me ke kila wikiwiki. Ma muli o kona kumukūʻai haʻahaʻa, ʻaʻole ia e hoʻohana wale ʻia no ka wili ʻana i nā ʻāpana wili, akā hoʻohana nui ʻia hoʻi i ka hoʻohuli ʻana i nā mea hana.

ʻO ke kila wikiwiki kiʻekiʻe Cobalt (HSSCO):

ʻOi aku ka paʻakikī a me ka paʻakikī ʻulaʻula o ke kila wikiwiki i loaʻa i ka cobalt ma mua o ke kila wikiwiki, a ʻo ka hoʻonui ʻia o ka paʻakikī e hoʻomaikaʻi pū i kona kūpaʻa ʻana i ka ʻaʻahu, akā i ka manawa like e mōhai ana i kahi hapa o kona paʻakikī. ʻO ia hoʻi ke kila wikiwiki: hiki ke hoʻohana ʻia e hoʻomaikaʻi i ka helu o nā manawa ma ka wili ʻana.

 

ʻO ke kalapona (CARBIDE):

He mea hui metala ka carbide i hoʻopaʻa ʻia. I waena o lākou, hoʻohana ʻia ka tungsten carbide ma ke ʻano he matrix, a hoʻohana ʻia kekahi mau mea o nā mea ʻē aʻe ma ke ʻano he mea hoʻopaʻa e hoʻopaʻa ʻia e kahi moʻo o nā kaʻina hana paʻakikī e like me ke kaomi isostatic wela. Ke hoʻohālikelike ʻia me ke kila wikiwiki ma ke ʻano o ka paʻakikī, ka paʻakikī ʻulaʻula, ke kūpaʻa ʻana i ka ʻaʻahu, a pēlā aku, aia kahi hoʻomaikaʻi nui, akā ʻoi aku ke kumukūʻai o nā mea hana carbide i hoʻopaʻa ʻia ma mua o ke kila wikiwiki. ʻOi aku ka maikaʻi o ka Carbide ma mua o nā mea hana ma mua ma ke ʻano o ke ola o ka mea hana a me ka wikiwiki o ka hana ʻana. I ka wili pinepine ʻana o nā mea hana, pono nā mea hana wili ʻoihana.

Pehea e koho ai i kahi uhi drill

Hiki ke hoʻokaʻawale ʻia nā ʻaʻahu i loko o nā ʻano ʻelima e like me ka laulā o ka hoʻohana.

ʻAʻohe i uhi ʻia:

ʻO nā pahi i uhi ʻole ʻia ka mea makepono loa a hoʻohana pinepine ʻia e wili i nā mea palupalu e like me nā mea hao alumini a me ke kila palupalu.

Uhi ʻokikene ʻeleʻele:

Hiki i nā uhi oxidized ke hāʻawi i ka lubricity ʻoi aku ka maikaʻi ma mua o nā mea hana i uhi ʻole ʻia, a ʻoi aku ka maikaʻi ma ke ʻano o ka oxidation a me ke kūpaʻa wela, a hiki ke hoʻonui i ke ola lawelawe ma mua o 50%.

Uhi ʻia ʻana o ka titanium nitride:

ʻO Titanium nitride ka mea uhi maʻamau a ʻaʻole kūpono no nā mea hana me ka paʻakikī kiʻekiʻe a me ka mahana hana kiʻekiʻe.

ʻO ka uhi ʻana o ka titanium carbonitride:

Ua hoʻomohala ʻia ka Titanium carbonitride mai ka titanium nitride a he kiʻekiʻe ke kūpaʻa i ka mahana a me ke komo ʻana, ʻo ka poni a polū paha. Hoʻohana ʻia e mīkini i nā ʻāpana hana hao i hoʻolei ʻia ma ka hale hana ʻo Haas.

Uhi ʻana o ka Aluminium Nitride Titanium:

ʻOi aku ka paʻa o ka alumini titanium nitride i nā mahana kiʻekiʻe ma mua o nā uhi āpau i luna, no laila hiki ke hoʻohana ʻia i nā wahi ʻoki kiʻekiʻe. No ka laʻana, ka hana ʻana i nā superalloys. He kūpono nō hoʻi ia no ka hana ʻana i ke kila a me ke kila kila, akā ma muli o nā mea i loaʻa ka alumini, e hana ʻia nā hopena kemika i ka wā e hana ai i ka alumini, no laila e pale i ka hana ʻana i nā mea i loaʻa ka alumini.

ʻO ke ʻano o ka ʻūlū wili

Hiki ke hoʻokaʻawale ʻia nā hiʻohiʻona geometric i 3 mau ʻāpana:

Ka lōʻihi

Ua kapa ʻia ka lakio o ka lōʻihi i ke anawaena he anawaena pālua, a ʻo ka liʻiliʻi o ke anawaena pālua, ʻoi aku ka maikaʻi o ka paʻakikī. ʻO ke koho ʻana i kahi wili me ka lōʻihi o ka lihi no ka wehe ʻana i nā ʻāpana a me ka lōʻihi pōkole o ka overhang hiki ke hoʻomaikaʻi i ka paʻakikī i ka wā o ka mīkini ʻana, a laila e hoʻonui ai i ke ola lawelawe o ka mea hana. ʻO ka lōʻihi o ka pahi ʻaʻole lawa e hōʻino paha i ka wili.

Ke kihi o ka wēlau wili

ʻO ke kihi o ka wēlau wili o 118° paha ka mea maʻamau i ka mīkini ʻana a hoʻohana pinepine ʻia no nā metala palupalu e like me ke kila palupalu a me ka alumini. ʻO ka hoʻolālā ʻana o kēia kihi ʻaʻole ia he kikowaena ponoʻī, ʻo ia hoʻi, he mea hiki ʻole ke pale ʻia ka mīkini ʻana i ka lua kikowaena ma mua. ʻO ka kihi o ka wēlau wili 135° ka mea maʻamau he hana kikowaena ponoʻī. No ka mea, ʻaʻohe pono e mīkini i ka lua kikowaena, e lilo kēia i mea pono ʻole e wili kaʻawale i ka lua kikowaena, no laila e mālama ana i ka manawa nui.

Ke kihi helix

He koho maikaʻi kahi kihi helix o 30° no ka hapa nui o nā mea. Akā no nā wahi e pono ai ka hoʻoneʻe ʻana i nā ʻāpana maikaʻi a me kahi ʻoi ʻoki ikaika, hiki ke koho ʻia kahi wili me kahi kihi helix liʻiliʻi. No nā mea paʻakikī ke mīkini e like me ke kila kila, hiki ke koho ʻia kahi hoʻolālā me kahi kihi helix nui aʻe e hoʻoili i ka torque.
