Tiav yeeb nkab OD WT ntev, nto zoo, Ncaj, polishing lub defected yeeb nkab Visual thiab Dimensional soj ntsuam.
1. OD kam rau ua: (-0.75%D, +0.75%D).
Cov yeeb nkab kawg OD kam rau ua: ± 0.005D.
2.WT kam rau ua: (+15%t, -12.5%t).
3. Ovality ntawm cov yeeb nkab lub cev: ± 0.020D, Ovality ntawm qhov xaus: ± 0.015D.
Lub WT ntawm ib qho chaw ntawm cov yeeb nkab yuav tsum ntau tshaj 87.5% ntawm nominal phab ntsa thickness.
WT ntawm cov kav dej xaus yog ntsuas nrog micrometer.
Phab ntsa thickness ntsuas ntawm cov yeeb nkab lub cev yog ua los ntawm phau ntawv UT rau WT npog 3 rings los yog seem tag nrho ntawm cov yeeb nkab lub cev nrog 6 nyeem ntawm txhua ntu.
4. Cov yeeb nkab lub cev khoov degree: 0.20% ntawm cov yeeb nkab ntev ntsuas nrog cov kab qhia.
5. Cov yeeb nkab kawg khoov degree: yuav tsum tsis txhob ntau tshaj 3.0mm hauv 1.2m.Ntsuas nrog ib tug ncaj bar.
