ʻO ka wili ʻana he ʻano hana maʻamau i ka hana ʻana.Ke kūʻai ʻana i nā ʻāpana drill, hele mai nā mea drill i nā mea like ʻole a me nā kala like ʻole.No laila pehea e kōkua ai nā kala like ʻole o nā bit drill?He pili anei ke kala me ka maikai o ka bit drill?ʻO wai ka bit drill kala ʻoi aku ka maikaʻi e kūʻai?
ʻO ka mea mua, pono mākou e hoʻomaopopo i ka maikaʻi o kahi drill bit ʻaʻole hiki ke hoʻoholo wale ʻia e kona kala.ʻAʻohe pili pololei a hiki ʻole ke pale ʻia ma waena o ke kala a me ka maikaʻi.ʻO nā waihoʻoluʻu like ʻole o ka drill bit ma muli o nā ʻenehana hana like ʻole.ʻOiaʻiʻo, hiki iā mākou ke hana i ka hoʻoholo koʻikoʻi e pili ana i ke kala, akā ʻo nā ʻāpana haʻahaʻa haʻahaʻa o kēia lā e hana pū i kā lākou mau kala ponoʻī e loaʻa i ke ʻano o nā ʻāpana drill kiʻekiʻe.
No laila he aha nā ʻokoʻa ma waena o nā ʻāpana drill o nā kala like ʻole?
Loaʻa pinepine ʻia nā ʻāpana kila kiʻekiʻe kiʻekiʻe i ka lepo piha i ke keʻokeʻo.ʻOiaʻiʻo, hiki ke hoʻomaʻemaʻe ʻia ka bit drill i ʻōwili ʻia ma ka wili maikaʻi ʻana i ka pōʻai waho.ʻO ka mea e hana ai lākou i ke kiʻekiʻe kiʻekiʻe ʻaʻole wale ka mea ponoʻī, akā ʻo ka mana maikaʻi hoʻi i ka wā o ka wili.He koʻikoʻi loa ia a ʻaʻohe ʻā ma ka ʻili o ka mea hana.ʻO nā mea ʻeleʻele he Nitride drill bits.He hana kemika ia e kau ai i ka mea hana i hoʻopau ʻia i loko o ka hui ʻana o ka ammonia a me ka mahu wai a hana i ka mālama mālama ʻana i ka wela ma 540 ~ 560C ° e hoʻomaikaʻi i ka lōʻihi o ka mea hana.ʻO ka hapa nui o nā pahu drill ʻeleʻele i kēia manawa ma ka mākeke he ʻeleʻele wale nō ka waihoʻoluʻu (i mea e uhi ai i nā kuni a i ʻole ka ʻili ʻeleʻele ma ka ʻili o ka mea hana), akā ʻaʻole i hoʻomaikaʻi maikaʻi ʻia ka hopena hoʻohana maoli.
He 3 kaʻina hana no ka hana ʻana i nā bit drill.ʻO ka ʻōwili ʻeleʻele ka mea ʻino loa.ʻO nā keʻokeʻo keʻokeʻo he mau ʻaoʻao maʻemaʻe.No ka mea, ʻaʻole koi ʻia ka oxidation kiʻekiʻe, ʻaʻole e luku ʻia ke ʻano o ka palaoa o ke kila, hiki ke hoʻohana ʻia no ka ʻeli ʻana i nā mea hana me ka ʻoi aʻe o ka paʻakikī.Loaʻa i nā ʻāpana drill melemele-ʻeleʻele i ka cobalt, kahi kānāwai i ʻōlelo ʻole ʻia ma ka ʻoihana drill bit.ʻO nā daimana Cobalt he keʻokeʻo mua, akā ma hope ua hoʻohui ʻia i ka melemele-ʻeleʻele (ʻike mau ʻia ʻo amber).ʻO lākou kekahi o nā mea maikaʻi loa i kēia manawa.Loaʻa iā M35 (Co 5%) kahi kala gula i kapa ʻia ʻo titanium-plated drill bit, i hoʻokaʻawale ʻia i ka uhi hoʻonaninani a me ka uhi ʻoihana.ʻAʻole maikaʻi ka hoʻopololei ʻana, nani wale ke nānā aku.He maikaʻi loa ka hopena o ka electroplating ʻoihana.Hiki i ka paʻakikī ke hiki i ka HRC78, ʻoi aku ka kiʻekiʻe ma mua o ka paʻakikī o ka cobalt drill (HRC54 °).
Pehea e koho ai i kahi drill bit
No ka mea, ʻaʻole ʻo ka kala ke kumu no ka hoʻoholo ʻana i ka maikaʻi o kahi drill bit, pehea e koho ai i kahi drill bit?
Mai ka ʻike, ʻo ka ʻōlelo maʻamau, ʻo nā ʻāpana wili keʻokeʻo ka mea maʻamau i hoʻopaʻa ʻia i nā bits drill steel kiʻekiʻe a pono e loaʻa ka maikaʻi maikaʻi loa.Loaʻa i nā mea gula he titanium nitride coating a ʻoi aku ka maikaʻi a maikaʻi ʻole paha a hiki ke hoʻopunipuni i nā kānaka.ʻOkoʻa hoʻi ka maikaʻi o ka ʻeleʻele.Hoʻohana kekahi poʻe i ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa carbon mea hana kila, kahi maʻalahi i ka anneal a me ka ʻōpala, no laila pono ia e ʻeleʻele.
Aia nā hōʻailona kūʻai a me nā hōʻailona hoʻomanawanui ma ka shank o ka drill bit, i maʻa mau, a ʻaʻole maikaʻi loa ka maikaʻi o ka laser a me ka electro-etching.Inā loaʻa nā ʻaoʻao convex o nā mea i hoʻoheheʻe ʻia, hōʻike ia he maikaʻi ʻole ka maikaʻi o ka drill bit, no ka mea, ʻo ka convex outline o nā huaʻōlelo e hoʻokō ʻole i ka pololei o ka wili bit drill i nā koi.Hoʻopili maikaʻi ʻia ka lihi o ka huaʻōlelo i ka ʻili cylindrical o ka mea hana, a ʻo ka drill bit me ka ʻaoʻao maopopo o ka huaʻōlelo he maikaʻi maikaʻi.Pono ʻoe e ʻimi i kahi drill me kahi ʻoki maikaʻi ma ka piko.He maikaʻi loa ka ʻokiʻoki ʻana i nā ʻāpana ʻāina piha a hoʻokō i nā koi no nā ʻili helix, ʻoiai ʻaʻole maikaʻi ʻole ka maikaʻi o nā ʻili ʻili.
