Kupera kozungulira ndiye ntchito yofala kwambiri yopera. Ndi njira yomaliza yomwe imagwiritsa ntchito gudumu lozungulira lozungulira kuti liwongolere pamwamba pa zinthu zachitsulo kapena zosakhala zachitsulo kuti ziwoneke bwino kwambiri pochotsa oxide wosanjikiza ndi zinyalala pamalo ogwirira ntchito. Izi zipangitsanso kuti malo ofunikira akhale ogwirira ntchito.
Chopukusira pamwamba ndi chida chamakina chomwe chimagwiritsidwa ntchito kupereka malo olondola apansi, kaya kukula kofunikira kapena kuti pamwamba pake pakhale bwino.
Kulondola kwabwino kwa chopukusira pamwamba kumadalira mtundu ndi kagwiritsidwe ntchito kake, komabe ±0.002 mm (±0.0001 in) iyenera kukwaniritsidwa pa zopukusira pamwamba zambiri.
