Ke ʻano o nā ʻāpana Drill

ʻO ka drill bit kahi ʻano mea hana hoʻopau no ka hana ʻana i ka wili, a ʻo ka hoʻohana ʻana i ka drill bit i ka hoʻoheheʻe ʻana he mea nui loa;ʻo kahi drill bit maikaʻi hoʻi e pili ana i ke kumukūʻai hana o ka mold.No laila he aha nā ʻano maʻamau o nā drill bits i kā mākou hoʻoheheʻe ʻana??

ʻO ka mea mua, ua māhele ʻia e like me ka mea o ka drill bit, i hoʻokaʻawale pinepine ʻia i:

ʻO nā wili kila kiʻekiʻe (hoʻohana mau ʻia no nā mea palupalu a me ka wili ʻawaʻawa)

ʻO nā pahu pahu pahu kobalt (hoʻohana mau ʻia no ka hoʻoheheʻe ʻia ʻana o nā puka ʻeleʻele o nā mea paʻakikī e like me ke kila kila a me nā alloys titanium)

ʻO ke kila kila/tungsten carbide drills (no ka wikiwiki kiʻekiʻe, ka paʻakikī kiʻekiʻe, ka hana hole kiʻekiʻe)

Wahi a ka ʻōnaehana drill bit, maʻamau:

ʻO nā wili wili pololei (ke ʻano drill maʻamau)

ʻO nā drills micro-diameter (nā hoʻoheheʻe kūikawā no nā anawaena liʻiliʻi, ʻo ke anawaena o ka ʻili ma waena o 0.3-3mm)

Step drill (kūpono no ka hana ʻana i hoʻokahi ʻanuʻu o nā puka he nui, hoʻomaikaʻi i ka hana pono a me ka hōʻemi ʻana i nā kumukūʻai hana)

Ma muli o ke ʻano hoʻoluʻu, ua māhele ʻia i:

ʻO ka hoʻoheheʻe anuanu pololei (ka ninini ʻana i waho o ka mea hoʻoheheʻe, ʻo nā drills maʻamau ka mea maʻamau i nā drill anu pololei)

ʻO ka hoʻoheheʻe hoʻoluʻu kūloko (ʻo ka drill he 1-2 ka hoʻoluʻu ʻana ma nā lua, a hele ka mea hoʻomaha i nā lua hoʻoluʻu, e hoʻemi nui i ka wela o ka drill a me ka mea hana, kūpono no nā mea paʻakikī kiʻekiʻe a me ka hoʻopau ʻana)
