He pōkole ka lōʻihi o ka Mīkini Drill Bits no ka ʻoi aku o ka rigidity a me ka pololei o ka wili ʻana. Manaʻo ʻia no ka hoʻoheheʻe ʻana i ka lau metala, ke kila kila, ke kalaka a me nā kino home mobile.
Screw Machine Drill i kapa ʻia ʻo "stub drill". ʻOihana kaumaha kiʻekiʻe māmā kila. Hana ʻia ka ʻokikene ʻeleʻele, 135 degere māhele wahi. ʻO ka puʻupuʻu pōkole a me ka lōʻihi holoʻokoʻa e hoʻonui i ko lākou rigidity, e hopena i ka pololei o ka lua a me ke ola mea paahana.
ʻO ka ʻohe pōkole a me ka lōʻihi holoʻokoʻa e hoʻonui i ka rigidity, e hopena i ka pololei o ka lua a me ke ola mea paahana.
ʻO ke kila ikaika kiʻekiʻe o ka cobalt no ka pale ʻana i ka wela a me ke ola mea hana lōʻihi.
ʻO ka wili ʻana pololei ma muli o 135 Degree Split Point
Manaʻo ʻia no ka ʻeli ʻana i nā mea tensile kiʻekiʻe e like me ke kila kila, ka titanium, ke kila manganese, ka pā kaua a me ka iconel.
Nā pono
★ʻOi aku ka lōʻihi, ʻoi aku ka ʻino
ʻO nā Mīkini Screw Drills (ʻike pū ʻia ʻo stub a stubby drills) he hana pōkole a ʻoʻoleʻa e hana maikaʻi ana i ka laulā o nā mea i loko o ka ʻohana hao a me ke kila.
He mea kaulana nā drills mīkini ʻuila i ka ʻoihana kaʻa a me ke kūkulu hale. Hoʻohana pinepine ʻia lākou i ka hoʻonohonoho mīkini screw kahi i kaupalena ʻia ai ka ʻae ʻana o ka spindle.
★ʻO nā hoʻoheheʻe ʻana a me ka ikaika
He like nā Screw Machine Drills me ke kila kiʻekiʻe, akā me ka cobalt hou aʻe no ka hoʻomaikaʻi ʻana i ka hana i ka wā e ʻoki ai i nā metala ʻoi aku ka paʻakikī e like me ke kila kila a i ʻole nā nickel alloys.
Hana ʻia lākou i ka Aerospace Standard 907 me kahi wahi hoʻokaʻawale 135 degere e hoʻokaʻawale iā ia iho a hōʻemi i ka pana. ʻOi aku ka liʻiliʻi ma mua o ka 1/16 a ʻoi aku ka nui ma mua o ka 1/2 i loaʻa ka helu maʻamau 118 degere.
★Manaʻo Kaumaha Kaumaha
ʻO Drill America Screw Machine Drills he hana koʻikoʻi 135 degere māhele wahi no ka hoʻokaʻawale ʻana iā ia iho a me ka hoʻohaʻahaʻa ʻana i ka pahu. ʻOi aku ka liʻiliʻi ma mua o ka 1/16 a ʻoi aku ka nui ma mua o ka 1/2 i loaʻa ka helu maʻamau 118 degere.
