Kupera kwa Cylindrical
Kugaya kwa cylindrical (komwe kumatchedwanso center-type grinding) kumagwiritsidwa ntchito kugaya pamwamba pa cylindrical ndi mapewa a workpiece. Workpiece imayikidwa pa centre ndikuzunguliridwa ndi chipangizo chodziwika kuti center driver. Wheel abrasive ndi workpiece zimazunguliridwa ndi ma motors osiyana komanso pa liwiro losiyana. Tebulo likhoza kusinthidwa kuti lipange tapers. Mutu wa wheel ukhoza kuzunguliridwa. Mitundu isanu ya cylindrical grinding ndi: outside diameter (OD) grinding, inside diameter (ID) grinding, plunge grinding, creep feed grinding, ndi centerless grinding.
Kupera kwa M'mimba mwake wa Kunja
Kupera kwa OD ndi kuperedwa komwe kumachitika pamwamba pa chinthu pakati pa malo. Malo ndi mayunitsi omaliza omwe ali ndi mfundo yomwe imalola chinthucho kuzungulira. Gudumu loperedwa limazunguliridwanso mbali imodzi likakumana ndi chinthucho. Izi zikutanthauza kuti malo awiriwa azisuntha mbali zosiyana akakumana zomwe zimathandiza kuti ntchito ikhale yosalala komanso kuti pasakhale kugwedezeka.
Kupera kwa Mkati mwa Diameter
Kupukuta kwa ID ndi kupukuta komwe kumachitika mkati mwa chinthu. Gudumu lopukuta nthawi zonse limakhala laling'ono kuposa m'lifupi mwa chinthucho. Chinthucho chimagwiridwa ndi koleti, yomwe imazunguliranso chinthucho pamalo pake. Monga momwe zimakhalira ndi kupukuta kwa OD, gudumu lopukuta ndi chinthucho zimazungulira mbali zosiyana zomwe zimapangitsa kuti malo awiri omwe kupukuta kumachitika agwirizane mozungulira.
Kulekerera kwa chopukusira chozungulira kumakhala mkati mwa ±0.0005 mainchesi (13 μm) pa mainchesi ndi ±0.0001 mainchesi (2.5 μm) pa kuzunguliza. Ntchito yolondola imatha kufikira kulekerera kwakukulu mpaka ±0.00005 mainchesi (1.3 μm) pa mainchesi ndi ±0.00001 mainchesi (0.25 μm) pa kuzunguliza. Kumaliza pamwamba kumatha kuyambira 2 microinches (51 nm) mpaka 125 microinches (3.2 μm), ndipo kumaliza kwachizolowezi kumayambira 8 mpaka 32 microinches (0.20 mpaka 0.81 μm)
