Umshini wokupholisha ibhande le-GRINDMASTER crankshaft abrasive abrasive usetshenziselwa ukupholisha intamo yesivalo sikawoyela, ijenali eyinhloko, kanye nentamo yenduku yokuxhuma ye-crankshaft. Lapho upholishwa, i-workpiece iyafafazwa futhi ihlanzwe, bese izingxenye zipholishwa ngebhande eliqhumayo.
Kunezikhombisi-ndlela ezimbili zokuzungezisa ngesikhathi sokupholishwa, futhi isiqondiso sokugcina sokupholisha siyefana nendlela evamile yokugijima yenjini (ebukwa ohlangothini lwe-flywheel); ngemva kokupholishwa, ukupholishwa komiswe kanye nomsebenzi wokukhipha amafutha, futhi okokusebenza kudinga uhlelo lwayo lokwelapha uketshezi lokupholisha.
