Ua māhele ʻia nā ʻāpana drill i nā kala? He aha ka ʻokoʻa ma waena o lākou? Pehea e koho ai?

ʻokoʻa drill bits

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.

Aia 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.
