Lub phab ntsa tuab ntawm cov yeeb nkab yuav tsum, yuav muaj rau kev ua siab ntev ntawm +10%, yog ib qho ntawm cov nqi nyob hauv cov chaw nyob hauv qab no, tshwj tsis yog kev pom zoo ntawm cov khw thiab tus neeg yuav khoom.
-Strimness
Txhua qhov sib txawv ntawm cov yeeb nkab los ntawm txoj kab ncaj nraim, yuav tsis pub tshaj 0,2% ntawm qhov ntev ntawm cov yeeb nkab.
Ib qho tawm ntawm-ntawm-roundness (uas yog qhov tshwm sim los ntawm sag), ntawm cov kav dej ntawm sab nraud ntawm txoj kab uas loj dua li 500 ntawm cov taub sab nraud (izon) lossis 6 hli, qhov twg yog tsawg dua.
Thov nco ntsoov tias cov ntaub ntawv ntxaws ntxaws no muab cov ntaub ntawv qhia txogCov Ntxaib 719 Qib C Kav DejCov. Cov kev xav tau tshwj xeeb yuav txawv raws li txoj haujlwm thiab qhov tseeb ntawm cov yeeb nkab yuav tsum tau ua.
