Precision steel yeeb nkab yog ib yam ntawm cov khoom siv tau zoo steel yeeb nkab tom qab txias txias lossis kub dov. Vim tias qhov zoo ntawm tsis muaj txheej txheej oxide ntawm sab hauv thiab sab nrauv ntawm cov yeeb nkab steel, tsis muaj xau nyob rau hauv siab, siab ua tiav, ua tiav siab, tsis deformation thaum txias dabtsi yog khoov, tsis nthuav dav, flattening thiab tsis tawg, nws tsuas yog siv rau tsim cov khoom siv pneumatic lossis hydraulic, xws li lub tog raj kheej cua lossis lub tog raj kheej roj, uas tuaj yeem ua cov yeeb nkab lossis cov yeeb nkab txuas.
