ʻO nā mea hana pōhaku liʻiliʻi
ʻO ke koʻokoʻo drill tapered aliʻiliʻi liʻiliʻi.
ʻO ke koʻokoʻo ʻo tapered drill, kekahi inoa i kapa ʻia ʻo taper rod, tapered drill steels, Hāʻawi kēia i kahi ʻāpana hexagonal chuck e hāʻawi i ka leverage no ka rotation chuck bushing.Loaʻa iā ia kahi kola i hoʻopaʻa ʻia no ka mālama ʻana i ke kūlana o ke alo kuʻi ʻana o ka shank kūpono i ka lua pōhaku, a aliʻiliʻi liʻiliʻihopena.ʻO ka lōʻihi o ke kila liʻiliʻi— loaʻa mai ka 0.6 m a hiki i ka 8.0 m ka lōʻihi—e ana ʻia mai ke kola a hiki i ka hopena iki.
Shank Hexagon: 19 x108 mm, 22x 108mm, 25 x108 mm, 25 mmX159 mm, 7, 11, 12 degere taper i ka nui o ka lōʻihi, ʻo ke degere o ke kila drill ka hapa nui o ka lawe ʻia mai no ka huahana wili maikaʻi.
No ka wili ʻana i nā pōhaku ma waena-paʻakikī a paʻakikī a abrasive, hoʻohana maʻamau ʻia nā kihi liʻiliʻi o 11 a me 12-degere ma nā rig drill hou, e like me kāu kumu hoʻohālike no.PD-Y58 crawler hydraulic rock drill.No Y6, Y10, Y24, YT24, YT 27, Mobile rock drill pneumatic a hydraulic.
No nā haʻawina haʻahaʻa haʻahaʻa haʻahaʻa a me nā papa pōhaku palupalu, hoʻohana ʻia kahi ʻāpana lipine liʻiliʻi o 7 degere, e like me India, Saudi's granite a me marble quarry.
He laulā piha o nā ʻāpana pihi liʻiliʻi, nā ʻāpana keʻa a me nā ʻāpana chisel me 6, 7, 11, 12 degeretaper, anawaena puka lua: 28mm-57mm.
ʻOkoʻa ka ʻāpana pihi liʻiliʻi me ka ʻāpana pihi milo e like me ka ʻāpana puka lōʻihi e hoʻohana ai i ka paʻi liʻiliʻi me ka bit me ke koʻokoʻo e hoʻohana ʻia no ka wāwae ea a i ʻole ka lima paʻa ʻana i ka jack hammer driller i ka ʻeli ʻana, a me ka ʻeli ʻana.
