ʻO ke kila ʻoki manuahi e pili ana i ke kila kila e hoʻohui i kahi nui o hoʻokahi a ʻoi aku paha nā mea ʻoki manuahi e like me ka sulfur, phosphorus, lead, calcium, selenium, tellurium, etc. e hoʻomaikaʻi i kona machinability.Me ka automation, ka wikiwiki kiʻekiʻe a me ka pololei o ka ʻoki ʻana, he mea koʻikoʻi ke koi ʻana i ke kila e loaʻa ka machinability maikaʻi, ka mea i hoʻohana nui ʻia no ka hana ʻana i nā mīkini ʻoki ʻoki.Ke nānā aku nei kēia i nā ʻokoʻa ma waena o 1215 ʻoki kila manuahi a me 11SMn30 ʻoki kila manuahi.
ʻO 1215 kahi ʻano o ke kila ʻoki maʻalahi i ka moʻo maʻamau ʻAmelika ASTM/AISIBI.ʻO 1215 ke kila ʻoki manuahi he mea pili kaiapuni i loaʻa ʻole ke alakaʻi a i ʻole nā mea ʻino i ke kaiapuni.Loaʻa iā ia nā waiwai ʻoki maikaʻi a kūpono i nā shafts electroplating maʻamau, nā mea ʻokiʻoki, a me nā ʻāpana maʻamau.
