Aia kekahi pilina ma waena o ka kala drill a me ka maikaʻi

ʻO ka mea mua: ʻaʻole hiki ke hoʻokaʻawale i ka maikaʻi o ka drill bit mai ke kala.ʻAʻohe pili pololei a hiki ʻole ke pale ʻia ma waena o ke kala a me ka maikaʻi.ʻOkoʻa nā ʻāpana drill kala ʻokoʻa i ka ʻenehana hana.ʻOiaʻiʻo, hiki iā ʻoe ke hana i kahi hoʻoholo koʻikoʻi mai ke kala, akā ʻo nā ʻāpana drill maikaʻi ʻole o kēia manawa E hana i kā lākou mau kala ponoʻī e hoʻokō i ke ʻano o nā drills kiʻekiʻe.

He aha ka ʻokoʻa ma waena o nā kala like ʻole

Hōʻike pinepine ʻia nā mea hoʻoheheʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe piha i ke keʻokeʻo.ʻOiaʻiʻo, hiki ke hoʻomaʻemaʻe ʻia nā ʻāpana drill i ʻōwili ʻia e ka wili maikaʻi ʻana o ka pōʻai waho.ʻO ke kumu o ke kiʻekiʻe kiʻekiʻe ʻo ia ka hoʻohui ʻana i ka mea ponoʻī, ʻo ka mana o ka maikaʻi i ka wā o ka wili ʻana he koʻikoʻi nō hoʻi, ʻaʻohe wela ma ka ʻaoʻao o ka mea hana.ʻO ka ʻeleʻele kahi drill bit nitrided.He ala kemika ia e hoʻomaikaʻi ai i ka lōʻihi o ka mea hana ma ka waiho ʻana i ka mea hana i hoʻopau ʻia i loko o ka hui ʻana o ka ammonia a me ka mahu wai a waiho ʻia i kahi mahana o 540-560C °.

I kēia manawa, ʻeleʻele wale ka hapa nui o nā hana ʻeleʻele ma ka mākeke (i mea e uhi ai i ke kuni a i ʻole ka ʻili ʻeleʻele ma ka ʻili o ka mea hana), akā ʻaʻole i hoʻomaikaʻi maikaʻi ʻia ka hopena hoʻohana maoli.

ʻEkolu kaʻina hana no ka hana ʻana i nā bit drill.'Oloka'a 'ele'ele, 'o ka 'ino loa.Hoʻokiʻoki ʻia nā mea keʻokeʻo a hoʻonani ʻia.ʻAʻole like me ka ʻōwili ʻana, ʻaʻole ia e hoʻohua i ka oxidation wela kiʻekiʻe, ʻaʻole i hōʻino ʻia ke ʻano o ka palaoa o ke kila, a hoʻohana ʻia e wili iki i nā mea hana paʻakikī.Ua kapa ʻia ka drill bit tan drill i loko o ka ʻoihana.ʻO kēia ke kānāwai huna o kēia ʻoihana drill.

He keʻokeʻo mua nā daimana Cobalt a hana ʻia ma ka wili ʻana.I ka wā i ʻātomai ʻia ai lākou ma hope, ua hana ʻia lākou i melemele-ʻeleʻele (i kapa ʻia ʻo amber), ʻo ia ka mea maikaʻi loa i ke kahe ʻana i kēia manawa.M35 (Co 5%) he kala gula.Kapa ʻia kēia ʻano drill i ka titanium-plated drill, i hoʻokaʻawale ʻia i ka plating decorative a me ka plating industrial.ʻAʻohe hopena o ka pāpale hoʻonaninani, nani a gula.He maikaʻi loa ka hoʻopili ʻana i ka ʻoihana, hiki i ka paʻakikī ke hiki i ka HRC78, ʻoi aku ka kiʻekiʻe ma mua o nā daimana cobalt (HRC54 °).

No ka mea, ʻaʻole ʻo ke kala ke kumu no ka hoʻoholo ʻana i ka maikaʻi o kahi drill, pehea ʻoe e kūʻai ai i kahi drill?

Ma ka hoʻoholo ʻana mai ka ʻike, ma ka laulā, hana ʻia ke keʻokeʻo i ka bit drill bit kiʻekiʻe, ʻoi aku ka maikaʻi o ka maikaʻi.ʻO nā mea gula he titanium nitride i uhi ʻia a ʻoi aku ka maikaʻi a maikaʻi ʻole paha.ʻAʻole like ka maikaʻi o ka ʻeleʻele.Hana ʻia kekahi me ke kila kila kalapona maikaʻi ʻole, he maʻalahi ke hoʻopili a maʻalahi hoʻi i ka ʻōpala, no laila pono e ʻeleʻele.

ʻO ka maʻamau, ke kūʻai ʻoe i kahi drill, hiki iā ʻoe ke ʻike i ka hōʻailona ma ka shank drill a me ka hōʻailona hoʻomanawanui.Akaka ka hōʻailona, ​​a ʻaʻole maikaʻi loa ka maikaʻi o ka laser a i ʻole ka uila.Ina he ano embossed ia, ina ua bulging ka lihi o ke ano, ua ilihune ka maikai o ka drill, no ka mea, o ka contour o ka bulged ano e emi iho ai ka pololei o ka drill ma mua o ka pono, a me ka lihi o ke ano. akaka, maikaʻi loa a maikaʻi ke ʻano o ka ʻili cylindrical o ka drill shank Junctions.Eia kekahi, pili ia i ka ʻoki ʻoki o ka piko drill.He maikaʻi loa ka lihi o ka drill piha piha, kūpono ka ʻili spiral i nā koi, a maikaʻi ʻole ka maikaʻi ma ka ʻaoʻao kihi hope.
