Umatshini wokupolisha imigca ethe tye weglasi usetyenziswa kakhulu ngoku, oku kulandelayo kukwazisa ngeenzuzo zomatshini wokupolisha/wokuhombisa iglasi.

1. Umatshini wokugquma iglasi unezibonelelo zesakhiwo esiphambili, ukuqhobosha ngokuzenzekelayo, ukuchaneka okuphezulu kunye nokusebenza kakuhle kwiindawo zokucubungula iglasi. Ungasetyenziselwa ukugquma okunzulu kweemveliso zeglasi ezifana neetafile zekofu zeglasi kunye neengcango ezingenafreyimu, kwaye usetyenziswa kakhulu kwiifektri ezahlukeneyo zefenitshala.

2. Ngokubanzi, umatshini wokugquma iglasi ulungele iiglasi ezahlukeneyo ngobukhulu nobukhulu bokugrumba, ukujija kunye nokupolisha umphetho weglasi ethe tyaba. Umphetho orhabaxa, ukugrumba okucolekileyo, ukupolisha, umphetho osezantsi kunye nezinye iinkqubo zigqitywa ngexesha elinye, kwaye umphezulu weglasi emva kokugrumba unokufikelela esipilini; Isantya sinokulungiswa, isantya sinokutshintshwa, kwaye isantya sokondla sinokulungiswa ngokungakhethiyo ngexesha lenkqubo yokugrumba; Ubukhulu beeglasi ezahlukeneyo bunokucutshungulwa ngokutshintsha umqadi ongaphambili.

3. Ngokusebenza ngesandla nangokuzenzekelayo, kukho iintlobo ngeentlobo zeemodeli ezikhoyo, kwaye intloko yokusila ingadityaniswa kwiintlobo ngeentlobo zeefom, nto leyo enokwenza iglasi ibonise iimilo ezahlukeneyo kunye nembonakalo.
