Peb cov khoom siv raw yog los ntawm 320 * 480 loj-seem nruam nruam nruam camet los ntawm drilling cov yeeb nkab, thiab ua los ntawm 55simnmo lossis 95 crmo.Tag nrho cov khoom tsim muaj ntau yam txheej txheem, suav nrog steel dov, forging, quenching thiab tempering, thiab lwm yam. Raws li cov kev xaiv sib txawv ntawm cov neeg siv khoom, peb lub tuam txhab muaj cov khoom zoo sib txawv, xws li cov khoom siv ntxiv, zoo heev, zoo tib yam drilling pas nrig, thiab lwm yam. Cov neeg siv khoom tuaj yeem xaiv qhov tsim nyog drilling pas nrig raws li qhov sib txawv hardness ntawm pob zeb thiab hom jack rauj.Extra-zoo drilling pas nrig QSAAA thiab GTIII tuaj yeem siv rau cov pob zeb, III qib lossis siab dua thiab f≥12 pob zeb raws li Protodikonov's Hardness Coefficient of Rock.Qhov zoo tshaj plaws drilling pas nrig QSAA thiab G30 yog tsim rau IV qib lossis siab dua thiab f≥12 pob zeb, zoo tib yam drilling pas nrig haum rau IV qib lossis qis dua thiab f≤8 pob zeb.
