Ukusila ngeCylindrical
Ukugaya nge-cylindrical (okubizwa ngokuba yi-center-type grinding) kusetyenziselwa ukugawula imiphezulu ye-cylindrical kunye namagxa e-workpiece. I-workpiece ifakwe kwiziko kwaye ijikeleziswa sisixhobo esaziwa ngokuba yi-center driver. Ivili elirhabaxa kunye ne-workpiece zijikeleziswa ziimoto ezahlukeneyo kwaye ngesantya esahlukileyo. Itafile ingalungiswa ukuze ivelise ii-tapers. Intloko yevili ingajikeleziswa. Iintlobo ezintlanu zokugaya nge-cylindrical zezi: ukugaya nge-outside diameter (OD), ukugaya nge-inside diameter (ID), ukugaya nge-plunge, ukugaya nge-creep feed, kunye nokugaya ngaphandle kwe-centerless.
Ububanzi bokuGcada ngaphandle
Ukusila kwe-OD kukusila okwenzeka kumphezulu wangaphandle wento ephakathi kweziko. Iziko ziiyunithi zokugqibela ezinenqaku elivumela into ukuba ijikeleziswe. Ivili lokusila nalo lijikeleziswa kwicala elifanayo xa lidibana nento. Oku kuthetha ukuba ezi ndawo zimbini ziya kuhamba kwicala elichaseneyo xa kudityaniswa into, nto leyo evumela ukusebenza kakuhle kwaye amathuba okuxinana anciphe.
Ububanzi bokuGcada ngaphakathi
Ukusila nge-ID kukusila okwenzeka ngaphakathi kwento. Ivili lokusila lihlala lincinci kunobubanzi bento. Into ibanjwe endaweni yi-collet, ekwajikeleza into endaweni yayo. Kanye njengokuba kunjalo ngokusila nge-OD, ivili lokusila kunye nento zijikeleza kwicala elahlukileyo zinika unxibelelwano olubuyela umva lweendawo ezimbini apho ukusila kwenzeka khona.
Ukunyamezelana kokugaya okusilinda kugcinwe ngaphakathi kwe-±0.0005 intshi (13 μm) yobubanzi kunye ne-±0.0001 intshi (2.5 μm) yokujikeleza. Umsebenzi ochanekileyo unokufikelela kumlinganiselo ofikelela kwi-±0.00005 intshi (1.3 μm) yobubanzi kunye ne-±0.00001 intshi (0.25 μm) yokujikeleza. Ukugqitywa komphezulu kunokuqala kwi-2 microinches (51 nm) ukuya kwi-125 microinches (3.2 μm), kunye nokugqitywa okuqhelekileyo ukusuka kwi-8 ukuya kwi-32 microinches (0.20 ukuya kwi-0.81 μm)
