Kaʻina wili

01
Nā hiʻohiʻona o ka ʻeli ʻana
ʻElua mau kihi ʻoki nui i ka drill, i ʻoki ʻia i ka wā e huli ana ka drill.ʻOi aku ka nui a ʻoi aku ka nui o ka rake Angle o ka bit mai ke koʻikoʻi waena a i ka lihi o waho.ʻO ka pili kokoke i ka pōʻai waho, ʻoi aku ka kiʻekiʻe o ka wikiwiki ʻoki o ka bit.Hoʻemi ka māmā ʻoki i ke kikowaena, a ʻo ka wikiwiki o ka ʻoki ʻana o ke kikowaena rotary o ka bit he zero.Aia ka ʻaoʻao o ka drill ma kahi kokoke i ke axis o ke kikowaena rotary, a ʻo ka ʻaoʻao rake Angle o ka ʻaoʻao keʻa he nui, ʻaʻohe wahi hoʻomanawanui chip, a haʻahaʻa ka wikiwiki o ka ʻoki ʻana, no laila e hoʻopuka i kahi kūʻē axial nui. .Hiki ke ho'emi 'ia ke kū'ē 'oki 'ana a hiki ke ho'omaika'i maika'i 'ia ka hana 'oki 'ana inā ho'oma'ama'a 'ia ka lihi o ka 'ao'ao transverse i ke 'ano A a i 'ole C ma DIN1414 a 'o ka 'oki kokoke i ke axis waena he A positive rake Angle.

E like me ke ʻano o ka mea hana, ka mea, ka hale, ka hana, a me nā mea ʻē aʻe, hiki ke hoʻokaʻawale ʻia ka drill i nā ʻano he nui, e like me ka HSS drill (twist drill, group drill, flat drill), solid carbide drill, indexable shallow hole drill, deep hole drill. , wili pūnana a me ka wili poʻo hiki ke hoʻololi.

ʻO ka uhaʻi ʻana a me ka wehe ʻana i ka chip
Hana ʻia ka ʻoki ʻana i ka bit i loko o kahi puka haiki, a pono e hoʻokuʻu ʻia ka chip ma ka ʻaoʻao o ka bit, no laila ke ʻano nui ka mana o ke ʻano o ka ʻāpana i ka hana ʻoki ʻana o ka bit.ʻOpiʻi puʻupuʻu maʻamau, chip tubular, chip needle, chip spiral conical, chip lipine, chip fan, chip pauda a pēlā aku.
Ke kūpono ʻole ke ʻano o ka chip, e kū mai nā pilikia penei:

① Hoʻopaʻa nā ʻāpana maikaʻi i ka ʻaoʻao o ka ʻaoʻao, pili i ka pololei o ka wili ʻana, hōʻemi i ke ola drill, a hiki i ka haki ʻana o ka drill (e like me ka pauka, nā pahu pā, a pēlā aku);
② Hoʻopili ʻia nā ʻāpana lōʻihi a puni ka drill, ke keʻakeʻa nei i ka hana ʻana, e hōʻino ai i ka drill a i ʻole ke kāohi ʻana i ka wai ʻoki i loko o ka lua (e like me nā ʻāpana spiral, nā ʻāpana lipine, etc.).

Pehea e hoʻoponopono ai i ka pilikia o ke ʻano chip kūpono ʻole:
① Hiki ke hoʻohana ʻokoʻa a i hui pū ʻia e hoʻonui i ka hānai, ka meaʻai manawaleʻa, ka wili ʻana, ka ʻoki ʻoki a me nā ʻano hana ʻē aʻe e hoʻomaikaʻi ai i ka haki ʻana a me ka hopena wehe, hoʻopau i nā pilikia i hana ʻia e ka ʻoki ʻoki.
Hiki ke hoʻohana ʻia ka drill breaker chip professional no ka wili ʻana.No ka laʻana, ʻo ka hoʻohui ʻana i kahi pahi wāwahi chip i ke awāwa o ka bit e wāwahi i ka chip i nā ʻōpala i ʻoi aku ka maʻalahi.Wehe ʻia ka ʻōpala ma ka ʻauwaha me ka ʻole o ka pipili ʻana i ka ʻauwaha.No laila, hiki i ka mea wāwahi chip hou ke hoʻokō i nā hopena ʻoki maʻalahi ma mua o nā bits kuʻuna.

I ka manawa like, ʻoi aku ka maʻalahi o ka holo ʻana o ka mea hoʻomaha i ka piko drill, e hoʻomaikaʻi hou i ka hopena wela a me ka ʻoki ʻana i ka hana ma ke kaʻina hana.A ma muli o ka hele ʻana o ka mea wāwahi chip hou ma ke awāwa holoʻokoʻa o ka bit, e mau ana kona ʻano a me kāna hana ma hope o ka wili pinepine ʻana.Ma waho aʻe o kēia mau hana hoʻomaikaʻi, pono e haʻi ʻia e hoʻonui ka hoʻolālā i ka rigidity o ke kino drill a hoʻonui nui i ka nui o nā lua i wili ʻia ma mua o kahi ʻoki hoʻokahi.

pololei wili
ʻO ka pololei o ka puka ka mea nui i ka nui o ka puka, ka pololei o ke kūlana, ka coaxiality, ka pōʻai, ka ʻili a me ka orifice burr.
ʻO nā kumu e pili ana i ka pololei o nā lua i wili ʻia i ka wā wili:

(1) Bit clamping pololei a me ka ʻoki ʻana i nā kūlana, e like me ka clip cutter, ka wikiwiki o ka ʻoki ʻana, ka hānai ʻana, ka ʻoki ʻana i ka wai, etc.;
② ʻO ka nui o ka bit a me ke ʻano, e like me ka lōʻihi o ka bit, ke ʻano o ka lihi, ke ʻano kumu, a pēlā aku;
(3) ʻano mea hana, e like me ke ʻano ʻaoʻao orifice, ke ʻano orifice, ka mānoanoa, ke kūlana clamping, etc.
