Cylindrical Akupera
Cylindrical akupera (omwe amatchedwanso pakati-mtundu akupera) amagwiritsidwa ntchito pogaya cylindrical pamwamba ndi mapewa workpiece.Chogwirira ntchitocho chimayikidwa pazigawo ndikuzunguliridwa ndi chipangizo chomwe chimadziwika kuti dalaivala wapakati.Gudumu la abrasive ndi workpiece amazunguliridwa ndi ma motors osiyana komanso kuthamanga kosiyana.Gome likhoza kusinthidwa kuti likhale ndi tapers.Mutu wa gudumu ukhoza kuzunguliridwa.Mitundu isanu ya kupera kwa cylindrical ndi: kugaya kunja kwake (OD) kugaya, kugaya mkati (ID) kugaya, kugaya, kugaya chakudya chokwawa, ndi kugaya kopanda pakati.
Kunja Diameter Akupera
Kugaya kwa OD ndikupera komwe kumachitika kunja kwa chinthu pakati pa malo.Malowa ndi mayunitsi omalizira okhala ndi mfundo yomwe imalola kuti chinthucho chizizunguliridwa.Chipwe chocho chikungunuka ngwo katamba kunyingika ngwo yuma yino yinasolola ngwo.Izi zikutanthawuza kuti mbali ziwirizi zikuyenda mosiyana pamene kukhudzana kwapangidwa komwe kumapangitsa kuti ntchito ikhale yabwino komanso mwayi wochepa wa kupanikizana.
Mkati Diameter Kugaya
Kupera kwa ID ndikupera komwe kumachitika mkati mwa chinthu.Gudumu lopera limakhala laling'ono nthawi zonse kuposa m'lifupi mwa chinthucho.Chinthucho chimagwiridwa ndi collet, yomwe imazunguliranso chinthucho.Monga momwe zimakhalira ndi OD kugaya, gudumu lopera ndi chinthucho zimazungulira mbali zosiyanasiyana zomwe zimapatsa kukhudzana kwa mbali ziwiri zomwe kugaya kumachitika.
Kulekerera kwa cylindrical mphero kumachitika mkati mwa ± 0.0005 mainchesi (13 μm) m'mimba mwake ndi ± 0.0001 mainchesi (2.5 μm) pozungulira.Ntchito yolondola imatha kufikira mainchesi ± 0.00005 (1.3 μm) m'mimba mwake ndi ± 0.00001 mainchesi (0.25 μm) pakuzungulira.Zomaliza zam'mwamba zimatha kuyambira 2 microinches (51 nm) mpaka 125 μm (3.2 μm), zomaliza zoyambira 8 mpaka 32 μm (0.20 mpaka 0.81 μm)
