He aha ke kila mīkini manuahi?
ʻO ke kila ʻoki manuahi kahi inoa kapakapa no ke kila kalapona me nā mea hoʻohuihui hou no ke kumu wale nō o ka hoʻomaikaʻi ʻana i ko lākou machinability a me ka mana chip. Ua kapa ʻia hoʻi lākou he mau mea Free-Cut a i ʻole Free-Cutting.
Ua māhele ʻia nā kila mīkini manuahi i 3 mau hui liʻiliʻi
lMoʻo 11xx: Ua hoʻonui ʻia ka nui o ka Sulfur (S) mai 0.05% i nā kila kalapona maʻemaʻe a i 0.1%. Hoʻohui ia ma kahi o 20% i ka machinability ke hoʻohālikelike ʻia me nā mea like ma ka moʻo 10xx. Ma ka ʻaoʻao ʻē aʻe, emi ka ikaika tensile ma kahi o 10%, a ʻoi aku ka palupalu o ka mea.
lMoʻo 12xx: Ua hoʻonui hou ʻia ka nui o ka Sulfur (S) i 0.25%, a ua hoʻonui ʻia ka nui o ka Phosphorus (P) mai 0.04% ma ka moʻo 10xx a i 0.5%. ʻO ka hopena, ua hoʻonui ʻia ka machinability e 40% hou aʻe ma ke kumukūʻai o ka emi hou ʻana o nā waiwai mechanical.
lSAE 12L14 he manuahi ʻoki ʻana i ke kila kahi i pani ʻia ai ka Phosphorus e 0.25% o ke kēpau (Pb), kahi e hoʻonui ai i ka mīkini ma kahi 35%. Hiki mai kēia hoʻomaikaʻi ʻana no ka mea hoʻoheheʻe ʻia ke kēpau ma kahi o ka ʻoki ʻana, no laila e hōʻemi ana i ka friction a hāʻawi i ka lubrication kūlohelohe. Eia nō naʻe, nui nā mea hana mea a me nā hale hana mīkini e hoʻāʻo e pale i nā mea hoʻohui kēpau ma muli o ka pōʻino o ke kaiapuni a me nā pilikia olakino.
Pehea e koho ai i ke kila ʻoki manuahi
ʻO Jindalai Steel he mea hana metala piha a alakaʻi, mea hoʻolako, mea hoʻokuʻu aku, mea hoʻolaha o nā ʻano huahana wili kila e like me ka paipu, ka tubing, ka pā a me ke koʻokoʻo. Pono e hana ʻia nā huahana kila e mākou mai nā mea maka maikaʻi loa a hiki ke hōʻoia piha ʻia i nā kikoʻī ʻoihana e like me ASTM a me ASME a i ʻole nā kūlana pili ʻē aʻe.ʻO Jindalai Steel hoʻolako a mālama i kahi waihona nui o ASTM 12L14, AISI 12L14, SAE 12L14 (SUM24L / 95MnPb28 /Y15Pb) nā ʻāpana mīkini poepoe e like me nā mea kani a me nā mika, nā ʻāpana wati, ke kaʻa, nā mea hana mīkini a me nā ʻano mīkini ʻē aʻe ma ka hoʻohana ʻana i nā ʻāpana maʻamau, e like me nā bolts, nā mea ʻokiʻoki, bushing, pine, a me ka wili mīkini, ka hoʻoheheʻe plastik, nā lako ʻokiʻoki a me nā niho, a pēlā aku. No ka ʻike hou aku, e ʻoluʻolu e kelepona mai iā mākou..
