Anamaliza chitoliro OD WT kutalika, khalidwe pamwamba, Kuwongoka, kupukuta chitoliro chopunduka Kuwona ndi Dimensional Inspection.
1. Kulekerera kwa OD: (-0.75%D + 0.75%D).
Chitoliro chimatha kulolerana kwa OD: ± 0.005D.
Kulekerera kwa 2.WT: (+ 15% t, -12.5% t).
3. Ovality ya thupi la chitoliro: ± 0.020D, Ovality ya mapeto: ± 0.015D.
WT pa malo aliwonse a chitoliro adzakhala oposa 87.5% mwadzina khoma makulidwe.
WT pamapaipi kumapeto amayezedwa ndi micrometer.
Kuyeza makulidwe a khoma pa thupi la chitoliro kumachitidwa ndi buku la UT la WT lophimba mphete 3 kapena gawo lonse la chitoliro ndikuwerenga 6 pagawo lililonse.
4. Digiri yopindika thupi la chitoliro: 0.20% ya kutalika kwa chitoliro Kuyesedwa ndi mzere wophunzitsidwa.
5. Chitoliro mapeto bend digiri : Siyenera kukhala oposa 3.0mm mu 1.2m.Kuyezedwa ndi bala yowongoka.
