Hoʻopili nā mea hana abrasive i ke kaʻina hana holoʻokoʻa o ka bearing, e like me ke apo bearing a me ka roller cross-section grinding, centerless grinding, loko a me waho apo channel grinding, bearing internal grinding, etc.

ʻO ka huila wili i hoʻohana ʻia e ʻoki i ka raceway o ka bearing e hoʻohana i nā abrasive hui ʻia kiʻekiʻe a me nā mea hoʻopaʻa hana kūikawā e hana i nā hiʻohiʻona pulverization maikaʻi i nā abrasive wili a mālama i kāna hana ʻoki. I ka manawa like, ʻo ka mea hoʻopaʻa paʻa he ikaika kulou maikaʻi a me ka elasticity mold liʻiliʻi, maʻalahi ka mālama ʻana i ke ʻano i hoʻololi ʻia, a hiki ke hōʻoia i ka pololei o ka wili ʻana o ka raceway.
