Conventionally kugaya kunoratidzwa seyakaderera kubviswa kwezvinhu zvinokwanisa kupa zvese zviri zviviri kurongeka kwepamusoro uye kupedzisa kwepamusoro. Zvakadaro, kuuya kwemichina yekukuya nemavhiri akakwira zvakasimudza chimiro chekukuya kusvika kune abrasive machining uko kurongeka kwepamusoro uye kupera kwepamusoro pamwe nechiyero chepamusoro chekubvisa zvinhu zvinogona kuwanikwa kunyangwe pachinhu chisina kuomeswa.

Uchishandisa yakakosha yekubatanidza mumiriri uye yakasarudzika tekinoroji yekugadzira, vhiri rekukuya rine kugaya kwakapinza, kupisa kwakaderera kwekukuya uye kugona kukuru kwekukuya. Kuchengetwa kwakanaka kwechimiro cheiyo workpiece, hapana kutsva. Kurongeka kwedimensional yegumbo rekukuya kunoenderana, flatness iri pasi pe0.1 mm, uye coaxiality iri pasi pe 0.1 mm, iyo iri nyore kusanganisa nekushandisa. Inoshandiswa mukukuya kweakasiyana akarongeka etsvimbo muindasitiri inotakura uye indasitiri yemotokari.

Surface finishing; kucheka nekuparadzana; kuderera, kuderera; kubviswa kwemasheya kupera kwe flat pamwe ne cylindrical surface; kukuya midziyo nekucheka nekurodzazve zvimwe chetezvo.
